A supply line lets go behind the washing machine on a Tuesday. By Thursday the back of that drywall can be growing mold. The Georgia Department of Public Health puts the window at 24 to 48 hours: when a wet surface or material is not dried or discarded promptly, molds can grow in that time, and the example the department gives is water from a burst pipe.
GA Water Damage is a free referral service that connects callers with independent local mold and water damage providers. It is not a remediation company or a contractor, and it does no testing, cleanup or repair work itself. Call the number on this page and you are connected with an independent provider; the scope, the price and the schedule are settled between you and that provider.
This page stays on one subject: mold that follows water. It covers how fast growth starts, what to do before anyone arrives, what a remediation job should include, what Georgia does and does not regulate, and what published guides say about cost and insurance.
Mold after water damage can start within two days
The state’s figure is not an outlier. The federal sources in the table below give the same window, and one of them starts the clock earlier. The EPA’s flood cleanup page says mold can grow on wood, drywall, carpet and furniture left wet for more than 24 hours.
| Source | What it says about timing |
|---|---|
| Georgia Department of Public Health | Mold can grow within 24 to 48 hours where a wet surface or material is not dried or discarded promptly |
| EPA | Water-damaged areas and items need to be dried within 24 to 48 hours to prevent mold growth |
| FEMA | Mold colonies can start to grow on a damp surface within 24 to 48 hours |
| OSHA (workplace bulletin) | A response within 24 to 48 hours, with thorough cleanup, drying or removal of wet materials, prevents or limits mold growth |
| Joint federal mold guide | A flooded home that was not dried within 24 to 48 hours should be assumed to have mold growth |
Treat the 48 hour mark as a guideline and not a guarantee in either direction. The EPA notes that mold does not always appear after 48 hours, and that it may have started even in materials that were dried inside that time. A wall that looks fine on day three has not been cleared, and a wall that sat wet for a week is not automatically ruined.
What the numbers do settle is the order of work. Drying a building before growth starts is a smaller job than taking growth out afterward, which is why the Department of Public Health advises cleaning, drying or removing anything water damaged within 24 to 48 hours. If the water is recent and nothing is growing yet, the page on water mitigation in Georgia is the one to read first.
If water has sat for more than a day or mold is already showing, one free call connects you with an independent local provider.
Mold removal and mold remediation: what each word covers
Mold removal means taking out the growth and the material it has ruined. Mold remediation includes that and two more things: correcting the moisture that fed the growth, and bringing the space back to a normal indoor condition. A quote that says only removal may be leaving the cause in place, so ask which one is being priced.
The trade standard for this work is the IICRC S520, Standard for Professional Mold Remediation, now in its Fourth Edition, published in 2024. Training summaries of the S520 describe a building by three conditions. Condition 1 is a normal indoor level of spores, Condition 2 is settled spores that have spread from a growth area, and Condition 3 is actual mold growth. The aim of remediation is to return the space to Condition 1.
The public guidance puts the water first as well. OSHA says a remediation plan should include steps to permanently correct the water or moisture problem. The joint guide issued by the CDC, EPA, FEMA, HUD and NIH says to fix the moisture problem as well as clean up the mold.
What to do today
The first hours are about stopping the water, staying safe and not making the growth worse. None of the steps below needs special equipment, and several of them are things not to do.
- Stop the water. Close the fixture valve or the main shut-off, or catch a roof leak, so the wet area stops growing.
- Turn the power off if wiring is wet or moldy. FEMA’s mold brochure says the main power should be off in that case. If reaching the panel means standing in water, the CDC’s advice is to leave it alone and call an electrician.
- Photograph everything before you move it. The joint federal guide puts contacting the insurer and photographing the home and belongings ahead of cleanup.
- Do not run fans once mold has started. Federal guidance says moving air can spread it.
- Do not touch mold or moldy items with bare hands.
- Do not paint or caulk over it. The EPA says moldy surfaces must be cleaned and dried before any painting, and the federal guide says covering mold will not stop the growth.
- Do not use a heating and cooling system that floodwater has touched. The EPA says such a system must not be used to help dry the house.
- Keep children out of the cleanup. The federal guide adds that people with asthma, other breathing problems or weakened immune systems should stay out of moldy spaces.
If the water was not clean
Water from a sewer backup, a river or a street carries more than moisture. The EPA’s advice when water or mold damage came from sewage or other contaminated water is to bring in a professional with experience in contaminated-water buildings, and not to set up fans until the water is known to be clean.
One more caution from the flood clean-up guide that the Department of Public Health links to: tell the insurer at once and photograph the damage, but do not wait for the adjuster before removing wet and moldy materials. Waiting costs days the building does not have.
Water stopped and photos taken? Call to be connected with an independent local provider who can look at what is wet and what is growing.
What a mold remediation job should involve
Providers differ in method and equipment, and the provider you are connected with sets its own scope for the job. The public guidance still describes a recognizable sequence, and knowing it lets you read a written scope and ask useful questions.
- Find and fix the moisture. A leak that is still feeding the wall makes every later step temporary. If a plumber or roofer is needed, that repair comes first or alongside.
- Assess the extent. Mold is often out of sight. Federal guidance names the space under or behind carpet, cushions and walls, and FEMA adds air ducts, attics, basements and wall cavities.
- Contain the work area. The EPA’s remediation guide, written for schools and commercial buildings, calls for limited containment for roughly 10 to 100 square feet of mold and full containment above 100 square feet, so that disturbed spores stay in the work area.
- Remove what cannot be saved. The same guide says unsalvageable moldy building materials and furnishings are double-bagged in 6-mil polyethylene for removal.
- Clean and dry what stays. Hard surfaces are cleaned and the structure is dried. FEMA’s published figure is that a wet area usually takes two to three days to dry completely.
- HEPA vacuum last. The EPA guide places HEPA vacuuming at the final cleanup of the remediation area, after the materials have been thoroughly dried.
- Rebuild only when dry. FEMA says rebuilding should wait until the area has dried completely. New drywall or paint over damp framing restarts the problem.
Size drives much of this. OSHA sorts mold jobs into four levels by area: 10 square feet or less, 10 to 30, 30 to 100, and more than 100 contiguous square feet. A written scope that states the square footage, the containment planned and the materials coming out is easier to compare with a second quote than a single lump sum.
The federal test for a finished job is plain enough to check yourself: no visible mold, no mold odor and no remaining signs of water damage. If any of the three is still present at the walk-through, raise it before the walls are closed.
Why Georgia grows mold
NOAA’s state climate summary describes Georgia as a place of long, hot and humid summers and short, usually mild winters. The outdoor air carries a lot of moisture for much of the year. NOAA’s long-term record for Atlanta, covering 1945 to 2018, shows average relative humidity of 81 percent in the morning and 55 percent in the afternoon, peaking at 87 percent on August mornings. Savannah’s average outdoor relative humidity across the year is 71.7 percent in the climate table of 1991 to 2020 normals.
Those are outdoor figures at two stations, not readings from inside anyone’s house. They matter because the indoor target is lower. The Georgia Department of Public Health advises keeping humidity in the home below 60 percent, ideally between 30 and 50 percent, and lists ventilating or dehumidifying attics, crawl spaces and basements among its prevention steps.
University of Georgia Extension gives similar advice: keep indoor relative humidity under 50 to 60 percent, and it lists water collecting in crawl spaces or basements among the sources of moisture that lead to mold. Its home inspection checklist, Circular 1083, suggests a dehumidifier when indoor humidity is over 50 percent and a 6 to 8 mil plastic vapor barrier over crawl-space soil.
After a flood
The flood clean-up guide linked by the Department of Public Health says to assume a building’s interior is seriously contaminated with mold if it was under water or wet for more than 48 hours. It also says a flooded crawl space has to be opened to air, with openings at opposite ends, for the house to dry. The claims and cleanup side of storm water has its own page: flood damage restoration in Georgia.
After a freeze
A split pipe in an attic, a crawl space or an outside wall can soak insulation and framing where nobody looks. Georgia’s emergency management agency told residents during the January 2025 winter weather to let pipes drip or insulate them so they would not freeze. When one does fail, the wet cavity is where mold starts; the first hours are covered under burst pipe water damage in Georgia.
By region
Conditions differ across the state, and the city pages on this site carry the local detail. For the coast, see water damage in Savannah, GA. For the Chattahoochee valley, see water damage restoration in Columbus, GA, and for northeast Georgia, water damage in Athens, GA. The metro Atlanta city pages are listed at the end of this page.
Does Georgia license mold remediation?
The Department of Public Health states the position directly. Indoor air quality is not a regulated program in Georgia, and mold inspections, testing and remediation practices have no enforceable state or federal standards. For indoor air quality the department’s Environmental Health Section regulates only tourist accommodations such as hotels and motels, and it offers no specific services for indoor mold growth.
On licensing, here is what the research for this site found. None of the Georgia sources reviewed names a state license or certification specific to mold remediation or water damage restoration companies. Those sources were the contractor and construction licensing chapters of the Georgia code, the Attorney General’s consumer guidance, the contractor board’s consumer tips and the Department of Public Health mold page. That is a finding from those sources, not a legal opinion, and a provider can confirm how it is licensed for the work it proposes.
What the state does license is the building work a mold job can lead to. The Attorney General’s office says general contractors, electricians, plumbers, and heating and air conditioning contractors must be licensed through the Secretary of State’s office. The statutory definition of a residential contractor applies where the value of the work exceeds 2,500 dollars, so a rebuild above that figure is worth a license question.
The Attorney General’s Consumer Ed site gives the steps for checking a contractor license: go to sos.ga.gov, choose Licensing, click Licensee Search, open the Building and Contractors tab and select Residential and General Contractors. Run the search before work starts, not after a dispute.
What to check when the state sets no mold standard
- Affiliation or certification. The joint federal guide tells people hiring help to look for a professional affiliated with or certified by NEHA, AIHA, the IICRC or the ACAC.
- Liability insurance. Ask for a certificate naming the provider, and read what it covers.
- A written scope. Area in square feet, containment, materials to be removed, how the moisture source is being corrected, and who rebuilds.
- Licenses for the licensed parts. Plumbing, electrical and heating and air work each need their own license in Georgia.
- How done will be judged. The federal three-part test is a fair starting point: no visible mold, no odor, no remaining water damage.
The footer of this site says the same thing in formal terms: providers are independent, and it is the owner’s responsibility to verify that the contractor hired carries the license and insurance the work requires. With no state mold standard behind the job, that check falls to the person signing the agreement.
Call to be connected with an independent local provider, and ask the questions above before you agree to a scope.
Is a mold test worth it before the work?
Federal guidance does not recommend routine mold sampling or testing. The reasoning in the joint guide is practical: whatever the type of mold, it has to be cleaned up and the moisture fixed, so a lab report naming the species does not change the job. Georgia has no enforceable standard to compare a result against either.
Some owners still pay for a separate inspection, and there are understandable reasons. One is wanting an assessment from someone who is not also pricing the removal. Others are a suspected source that cannot be seen, or a buyer, landlord or insurer asking for something in writing. Whether any of that is worth the fee is the owner’s call; this site makes no claim about how any provider handles testing.
What you can clean yourself
Public sources draw the line in different places, so the honest answer is a range. The state’s figure and the EPA’s sit close together, since a patch 3 feet by 3 feet is 9 square feet, and FEMA’s is higher. The Department of Public Health says a patch of surface mold smaller than 3 feet by 3 feet on hard plastic, tile, wood and some drywall can usually be cleaned by the homeowner, with a professional consulted for larger areas.
| Source | Size threshold | What it says |
|---|---|---|
| Georgia Department of Public Health | Under 3 feet by 3 feet | Surface mold on hard materials can usually be cleaned by the homeowner |
| EPA | About 10 square feet | The size limit for do-it-yourself cleanup |
| FEMA | More than 25 square feet, visible and concealed together | Consult a professional contractor |
| Flood clean-up guide linked by Georgia DPH | More than 100 square feet | Reports that EPA and CDC recommend trained mold remediation professionals |
For a small patch, the department says to wear plastic gloves, an N-95 rated filter mask and goggles, and that people sensitive to mold should not do the cleaning. The EPA’s routine method for hard surfaces is scrubbing with detergent and water and drying completely. Porous material that has grown mold, such as carpet, is a different matter; FEMA’s brochure says carpet that is soaked or already moldy is discarded.
What kills mold, answered honestly
People search for the product that kills mold, and the public guidance points somewhere less satisfying. The Department of Public Health says a bleach solution may be used to disinfect after cleaning but does not stop mold from coming back. The EPA does not recommend bleach or other biocides as a routine part of cleanup at all. FEMA’s brochure adds that disinfectants are meant for surfaces that have already been cleaned.
If bleach is used, the CDC’s mold page gives one cup in one gallon of water as the upper limit, and the state and federal guidance carries the same warning: never mix bleach with ammonia or other cleaners, because the fumes are toxic. No cleaner replaces drying the material and fixing the leak. Mold that is scrubbed off a surface that stays damp has every reason to return.
What mold does to health, stated plainly
The Department of Public Health says the most common health problem from mold is allergy symptoms, and that research has not established what levels of indoor exposure clearly cause serious health effects. That is a more measured statement than much of what is published about mold, and it is the state’s own.
The joint federal guide lists the effects of exposure as asthma attacks, eye and skin irritation and allergic reactions, with severe infections possible in people with weakened immune systems. Nothing on this page is medical advice. Anyone with symptoms they connect to a damp home should talk to a doctor, and the people the guide names should stay out of moldy rooms until the work is done.
Cost ranges from published guides
GA Water Damage does not set prices and has no price list. The provider quotes the job after seeing it. The only figures printed here are HomeAdvisor’s own national estimates, with their dates, as a rough frame for reading a quote.
| HomeAdvisor figure | Amount | Page and date |
|---|---|---|
| Average mold remediation cost | 2,368 dollars | Mold page, updated June 19, 2026 |
| Typical range | 1,223 to 3,757 dollars | Mold page, updated June 19, 2026 |
| Per square foot, most jobs | 10 to 25 dollars | Mold page, updated June 19, 2026 |
| Mold remediation range quoted in its water damage guide | 1,100 to 3,400 dollars | Water damage guide, updated June 17, 2026 |
These are national figures from one publisher, not Georgia prices and not a provider’s quote. What moves a real job within or beyond them is predictable: the area affected, where it is (an open wall is simpler than a crawl space or an attic), how much material has to come out, the level of containment, and whether the price includes putting the room back together. Ask whether the rebuild is in the number or quoted separately.
Insurance and mold in Georgia
Coverage turns on the wording of your own policy, and the insurer decides the claim. The standard reference is the ISO HO-3 homeowners form, and the 10 00 edition sample published by the Insurance Information Institute shows the usual shape. It excludes mold, fungus and wet rot, with one exception: mold concealed inside walls, ceilings or under floors that results from an accidental discharge or overflow of water.
Read plainly, that separates two cases. Mold hidden behind a wall after a pipe suddenly fails is the kind of case the sample form’s exception describes. Mold from a slow leak that went unrepaired runs into other language: the sample form excludes wear and tear, deterioration and faulty maintenance, and it excludes loss caused by neglect, meaning the owner’s failure to use all reasonable means to save the property at and after a loss. A real policy can differ from the sample, so the wording that counts is the wording in yours.
Flood insurance is stricter. FEMA’s flood insurance site says National Flood Insurance Program policies do not cover damage from mold, so the policyholder is expected to do everything possible to stop mold growing and spreading. After a flood, drying quickly and documenting it is part of protecting the claim as well as the house.
For questions or a dispute, the Consumer Services Division of Georgia’s Office of Commissioner of Insurance and Safety Fire answers insurance questions and helps resolve disputes between policyholders and insurers. Its phone lines are listed on that page.
A covered leak with mold behind the wall is time sensitive, so call to be connected with an independent local provider and notify your insurer the same day.
Renters and landlords
Renters search this topic as often as owners, and the state’s answer is short. The Department of Public Health regulates tourist accommodations but not private residences or rental properties, and it says that local housing codes generally contain no mold standard. Its advice to renters is to learn how the landlord-tenant relationship works in order to resolve a dispute.
The department points renters to three places: county or city officials, for questions about the local housing code; georgialegalaid.org; and the Georgia Landlord Tenant Handbook. This page states no rule on who must pay for mold work in a rental, because the sources reviewed for it do not set one out. Report the leak to the landlord in writing, keep dated photos, and use those three resources for the legal question.
Calling, cities and related pages
When you call, you are connected with an independent provider, who scopes and prices the job. Some participating providers take emergency calls at night and on weekends, but that depends on the provider and the location, as the availability notice in the footer states. More on how the service works is on the page about GA Water Damage, and the statewide overview is at water damage restoration in Georgia.
Each city page carries that place’s own water utility, permit office and flood history, which matter once mold work turns into a rebuild. Pick the one nearest the property.

Questions people ask
Mold removal or remediation: which word should be on the quote?
Remediation is the fuller word. Removal covers taking out the growth and the ruined material. Remediation also covers correcting the moisture that caused it and returning the space to a normal indoor condition, which summaries of the IICRC S520 call Condition 1. Whichever word a provider uses, ask whether the written scope names the moisture source and says who is fixing it.
How soon does mold start after a leak or flood?
The Georgia Department of Public Health says mold can grow within 24 to 48 hours where wet material is not dried or discarded promptly. FEMA and OSHA give the same window, and the EPA’s flood cleanup page says growth can begin on wood, drywall, carpet and furniture left wet for more than 24 hours. The EPA also notes the 48 hour mark is a guideline, not a guarantee either way.
How much does mold remediation usually cost?
Only a provider who has seen the job can price it, and GA Water Damage sets no prices. As a published reference, HomeAdvisor’s mold page, updated June 19, 2026, gives a national average of 2,368 dollars, a typical range of 1,223 to 3,757 dollars and 10 to 25 dollars per square foot for most jobs. Area, location in the house, containment and rebuild all move the figure.
Does homeowners insurance cover mold remediation?
It depends on your policy and the cause, and the insurer decides. The ISO HO-3 sample form, 10 00 edition, excludes mold except mold concealed in walls, ceilings or under floors that results from an accidental discharge or overflow of water. The same sample excludes deterioration, faulty maintenance and neglect. Real policies vary, so read yours and ask your agent before assuming either way.
Does flood insurance pay for mold?
FEMA’s flood insurance site says National Flood Insurance Program policies do not cover damage from mold, and that the policyholder is expected to do everything possible to stop mold from growing and spreading. In practice that means starting to dry the building and removing soaked material promptly after a flood, and keeping photos and receipts that show you did.
Does bleach stop mold from coming back?
No. The Georgia Department of Public Health says a bleach solution may be used to disinfect after cleaning but does not stop mold from returning, and the EPA does not recommend bleach or other biocides as a routine part of cleanup. Mold returns when the material stays damp, so drying it and fixing the leak is what prevents regrowth. Never mix bleach with ammonia or other cleaners.
Does Georgia license mold remediation companies, and what should I check before hiring one?
The Department of Public Health says mold inspection, testing and remediation have no enforceable state or federal standards, and none of the Georgia sources reviewed for this site names a state mold license. Check for liability insurance, a written scope, and affiliation with or certification by NEHA, AIHA, the IICRC or the ACAC, as the joint federal guide suggests. Plumbing, electrical and heating and air work need their own Georgia licenses.
How big a mold patch is too big to clean myself?
The published limits differ. Georgia’s Department of Public Health says under 3 feet by 3 feet of surface mold on hard materials can usually be handled by the homeowner. The EPA’s figure is about 10 square feet. FEMA says to consult a professional contractor above 25 square feet. Any amount tied to sewage or other contaminated water is not a household job, according to the EPA.
Is my landlord responsible for mold in a Georgia rental?
This page cannot answer that as a legal matter. The Department of Public Health says it does not regulate private residences or rental properties and that local housing codes generally contain no mold standard. It points renters to county or city officials, to georgialegalaid.org and to the Georgia Landlord Tenant Handbook. Report the leak in writing and keep dated photos while you get advice.
Do I need a mold test before remediation?
Federal guidance does not recommend routine mold sampling or testing. The joint guide from the CDC, EPA, FEMA, HUD and NIH reasons that whatever the type of mold, it has to be cleaned up and the moisture fixed. Georgia’s Department of Public Health adds that mold testing has no enforceable state or federal standards. Some owners still pay for a separate inspection when the source is hidden, or when a buyer, landlord or insurer wants something in writing.
Is black mold worse for health than other colors of mold?
The public sources used for this page do not rank mold by color. The joint federal guide says that whatever the type of mold, it has to be cleaned up and the moisture fixed. The Georgia Department of Public Health says the most common health problem from mold is allergy symptoms, and that research has not established what levels of indoor exposure clearly cause serious health effects. Anyone with symptoms should talk to a doctor.
Will mold come back after it is remediated?
It can if the material gets wet again, and nobody can honestly promise otherwise. OSHA says a remediation plan should include steps to permanently correct the water or moisture problem, and the joint federal guide says to fix the moisture as well as clean up the mold. The Georgia Department of Public Health advises keeping humidity in the home below 60 percent, ideally between 30 and 50 percent. Ask the provider what was done about the source.
Is this a mold remediation company? Who does the work when I call?
No. GA Water Damage is a free referral service, not a remediation company or a contractor. The call connects you with an independent local provider, and that provider inspects, scopes, prices and performs any work under its own agreement with you. Verifying the provider’s license and insurance for the work is the owner’s responsibility, as the footer of this site explains.
Does it cost anything to call?
No. GA Water Damage is a free service for callers, as the disclaimer in the footer says. Any work you go on to agree to is quoted and billed by the independent provider, and this site sets no prices. Before work starts, ask the provider for a written scope and a price, and ask whether an inspection or a visit carries a charge of its own.
