Growth on drywall behind a leak
Common behind a wall or ceiling that held water. The paper facing feeds the growth, and the board is cut out where the growth is visible. The framing behind it is cleaned and dried before the new board goes up.

Mold grows on wet organic material, such as paper facing, wood, carpet pad and dust, and it can begin within a day or two of a water loss if the material stays wet. The remedy is to dry the material quickly, remove the parts that cannot be cleaned and find the moisture that fed the growth. The cleanup records the readings and the removed material, and it does not promise that mold will never return.
Mold is a fungus that grows from spores that are present in most indoor and outdoor air. It needs moisture, a food source and time to take hold. A water loss supplies the moisture, and the paper on drywall, the wood in a subfloor and the carpet pad supply the food. The question after a water loss is not whether spores are present, but whether the wet material is drying quickly enough to stop growth from starting.
Mold after water damage often shows as a musty smell before it shows as a stain. The smell is a sign that growth is under way somewhere that is not visible, such as behind a wall, under a floor or in the insulation. A surface that has been wiped clean can still have growth in the material below, and the cleanup has to find the source of the moisture that fed the growth.
Do not disturb a large area of visible growth without containment and a mask. Wear a respirator rated for particles, gloves and eye protection for removal. People with asthma, allergies or a weakened immune system should not enter the work area while it is open. Keep children and pets out of the containment.
The first step is to find the water or the moisture that is feeding the growth. A leak, a damp cavity, a wet subfloor or a basement wall that has taken water must be stopped or dried, or the growth will return after it is removed.
Where there is visible growth, the area is sealed off with plastic sheeting and kept under negative air pressure, so spores are not carried into the rest of the house during removal. The work area is kept as small as the job allows.
Drywall, carpet pad, insulation and wood with visible growth that cannot be cleaned are removed and bagged. The removed material is taken out of the building promptly, and the removal is recorded with photographs.
Non-porous surfaces such as concrete, metal and sealed tile are cleaned with a detergent and then treated with an antimicrobial suited to the surface. A HEPA vacuum is used to remove loose spores and dust from the area before the containment is lifted.
The structure is dried to the dry standard, and the readings are kept as proof that the moisture that fed the growth has been removed. The repaired area is checked after the next heavy rain to confirm the moisture has not returned.
It can begin within a day or two when wet material stays wet, and the time depends on the material, the temperature and the air. Federal mold guidance is clear that drying wet material within about two days greatly reduces the risk.
The EPA guidance on mold after water damage is the usual reference for this timing, and it is written for clean water. Contaminated water starts the same growth but with more material to handle, so the cleanup is set to the category of the water.
The clock starts when the water arrives, not when the cleanup begins. A wet area left closed overnight can already be growing mold behind the surface, and that is why the drying is prioritized.
Sometimes, when the growth is on the surface of a non-porous material. Growth on drywall paper, wood that is soft or carpet pad is generally removed, because it cannot be cleaned to a safe level.
A surface cleaning can work on hard, non-porous material, but the same cleaning on drywall paper leaves the growth inside the board. The porous material is removed and replaced, and the framing behind it is cleaned and dried.
The decision is recorded for each material. The homeowner is shown where growth was found and what was removed, so the work can be checked against the record.
This site does not name a state license for mold work, because one has not been confirmed. Ask the company what it holds for the work, and ask what the local building department requires for any structural repair.
A homeowner should not rely on any license claim that a company makes without checking it. The question to ask is which credentials the company holds for mold remediation, which permits the job needs and which insurance covers the work. A company that cannot answer those questions is one to avoid.
The Colorado Division of Insurance is the state regulator for insurers, and it is the right office to call if a mold claim is denied. This site does not state what any policy covers for mold.
The record of the water event, the date it was found, the readings, the photographs of the growth and the material removed. A claim for mold is judged on when the moisture started and how quickly it was dried.
Many policies cover mold only when it follows a covered water loss and only up to a limit, and the limit and the conditions vary. The timing of the drying is part of the claim, so the record of when the water was stopped and when the structure was dried matters as much as the removal itself.
Keep the photographs, the readings, the removed material list and the invoice. Ask the insurer to explain in writing how it has treated the mold, and keep that letter with the file.
Common behind a wall or ceiling that held water. The paper facing feeds the growth, and the board is cut out where the growth is visible. The framing behind it is cleaned and dried before the new board goes up.
Basements and crawl spaces hold moisture and cool air, and growth can appear on the joists, the subfloor and the back of the wall. The soil and the framing are dried, and the source of the damp is found and corrected.
Pad and stored boxes that were wet for more than a day or two can show growth. These materials are generally removed, and the room is cleaned and dried before anything new is placed in it.
Mold in Colorado Springs homes is most often found in the basements, the crawl spaces and the closets on exterior walls after a water loss, where the air is cool and the moisture stays longest.
A house that had a storm or a burn-scar runoff event on its lower level should be checked for growth after the drying, even if the surfaces look clean. The 2013 runoff and the storms of 2016 and 2018 are the local reference points for water that reached lower floors.
A dry climate does not prevent growth inside a wall. The moisture in a damp cavity is what matters, and the readings show whether a cavity is still wet.
A crew is dispatched as fast as one is available, and you approve the estimate before any work starts.

Not always, but a musty smell after a water loss is a reason to look. The smell can come from wet material, dust or a drain, and the readings and the inspection show which.
Bleach is not a reliable answer on porous material, and it can give off fumes. Non-porous surfaces can be cleaned with a detergent, and porous material that is affected is generally removed rather than cleaned.
It can, if the moisture that fed it is not stopped. The cleanup finds and records the moisture source, and the homeowner should watch the area after the next heavy rain.
It is not always necessary. A visible growth area is removed whatever the test would show. A test can help where the source of a smell is unclear, and the homeowner can ask for one from a qualified tester.
