Professional mold remediation follows a set process: find and fix the moisture source, contain the work area, filter the air with HEPA equipment, remove contaminated porous materials, clean remaining surfaces, dry the structure, and confirm the area is clean before rebuilding. The IICRC S520 standard lays out these steps for mold remediation work.
If you’ve found mold after a leak in your Buckhead condo or your family home in Dunwoody, it helps to know what the crew will actually do once they arrive. Knowing the steps makes the whole thing feel a lot less mysterious, and it helps you ask good questions.
We work across Buckhead, Sandy Springs, Brookhaven, Chamblee, Dunwoody, Vinings and North Druid Hills, and the process is the same whether the job is a single bathroom wall or a full finished basement.
What is the difference between mold remediation and mold removal?
You’ll hear both terms, and people use them interchangeably. Mold spores exist naturally indoors and outdoors, so no one can honestly promise to remove every spore from a home.
Remediation means bringing mold back to normal levels, removing the growth and the damaged materials, and correcting the moisture problem that caused it. That last part matters most. The EPA is clear that if you don’t fix the water source, mold will come back.
What are the steps of professional mold remediation?
The IICRC S520 standard gives restoration companies a consistent framework. Here’s how it usually plays out on a real job.
- Inspection and moisture mapping. Technicians look at visible growth, then use moisture meters and thermal imaging to find wet materials you can’t see. The goal is to understand how far the moisture reached.
- Fixing the moisture source. A leaking pipe, a failed appliance line, or water entering from outside has to be stopped or repaired, or the work won’t hold.
- Containment. The crew seals off the affected area with plastic sheeting and often sets up negative air pressure. This keeps spores and debris from spreading into clean rooms while materials are disturbed.
- HEPA air filtration. Air scrubbers with HEPA filters run during the job to capture airborne particles stirred up by the work.
- Removal of contaminated porous materials. Drywall, insulation, carpet pad and ceiling tiles with growth usually can’t be cleaned well enough, so they’re cut out, bagged and removed.
- Cleaning. Framing, subfloors and other materials that stay are cleaned with HEPA vacuuming and appropriate cleaning methods.
- Drying. Dehumidifiers and air movers bring the structure back to normal moisture levels.
- Clearance. Before any rebuilding, the area is checked to confirm the remediation met its goals. Some homeowners also choose independent post-remediation testing.
What gets removed and what can be cleaned?
This is one of the first questions homeowners ask, because nobody wants to lose more of their home than they have to. The general rule under IICRC S520 is that porous materials with growth are removed, while non-porous and some semi-porous materials can often be cleaned.
| Material | Type | Typical approach |
|---|---|---|
| Drywall and ceiling tiles | Porous | Removed when growth is present |
| Fiberglass insulation | Porous | Removed and replaced |
| Carpet and carpet pad | Porous | Usually removed if growth is present |
| Wood framing and subfloor | Semi-porous | Often cleaned and dried if structurally sound |
| Tile, glass, metal | Non-porous | Cleaned in place |
Every job is judged on its own. A technician will explain what needs to go and why before anything is cut out.
How does remediation work in Atlanta condos and multi-level homes?
Buckhead has a real mix of housing, and each type changes how a remediation job is set up.
In high-rise condos and apartments along Peachtree Road, units often share walls, ceilings and plumbing stacks. A leak in one unit can affect the unit below or beside it. Containment has to respect those shared spaces, and building management is usually involved in scheduling, elevator access and approving work in common areas. If mold is found on your side of a shared wall, the source may be on the other side, so coordinating with the building matters.
In older multi-level homes in Brookhaven, Vinings and Sandy Springs, finished basements are a common place for remediation. These homes are often built into sloped, wooded lots, and water finds its way to the lower level. Crews may need to contain the basement from the stairwell up so work below doesn’t spread to living spaces above.
Atlanta’s humid climate also affects the drying step. With humid outdoor air for much of the year, containment and dehumidification have to be managed carefully so the work area actually reaches normal moisture levels instead of pulling in damp air from outside.
How do I know the remediation is actually finished?
Before walls go back up, you should be able to see a clean, dry work area with no visible growth or dust left behind. The crew should be able to show you final moisture readings that match normal, unaffected materials in your home.
Ask for a written summary of what was removed, what was cleaned, and what readings were taken. Those notes are useful for your own records, for your insurance company, and for a future buyer if you ever sell the home.
How can I prepare my home for a mold remediation crew?
A little preparation helps the job go smoothly and keeps your belongings safe.
- Move valuables, electronics and personal items out of the affected room if you can do so without disturbing moldy materials.
- Avoid running a central HVAC fan through an affected area until the crew advises you, since it can move particles through the ductwork.
- Let your condo association or building manager know about the work ahead of time.
- Photograph the damage and keep notes on when you found it. Document everything for your insurance company and check your policy for what it covers.
- Keep pets and kids out of the work area once containment goes up.
Frequently Asked Questions
How long does professional mold remediation take? It depends on how large the affected area is, how much material has to be removed, and how long drying takes. A technician can give you a working timeline after the inspection.
Do I have to leave my home during mold remediation? Often you don’t, because containment keeps the work area separate from the rest of the house. For larger jobs or in small condos, some families choose to stay elsewhere for part of the work.
Will mold come back after remediation? Mold returns when moisture returns. That’s why fixing the water source and drying the structure are part of the process, not optional extras.
Can I paint over mold instead of removing it? Paint doesn’t remove the growth or fix the moisture behind it. The growth can continue under the paint, and staining and odor usually come back.
Mold is stressful, but the fix follows a clear, proven process. Our IICRC-certified technicians follow the IICRC S520 standard for Mold Remediation and Removal, from containment to clearance, and we’ll walk you through every step, so call Best Option Restoration of Buckhead 24/7.
