How soon does mold start after a flood?
Mold can begin to grow on wet material within a short period, especially where moisture stays in a closed cavity and the air is warm. The exact timing depends on the material, the temperature and how long the material stays wet, so the drying is the control that matters.
Surfaces that dry quickly and are kept in moving air are much less likely to support growth than cavities that stay closed and wet. A wall that was soaked to the top plate and then sealed over is the classic case, because the moisture has nowhere to leave.
This is why the drying plan is measured and not assumed. Readings show whether the moisture is still moving out of the materials, and the crew adjusts the plan until it is. The owner gets the readings, so the progress can be seen.
Can mold be cleaned off framing and subfloors?
Framing and subfloors that are sound can often be cleaned and dried, but porous material such as drywall, insulation and carpet cannot be cleaned to a safe standard once growth is established. The crew decides which materials are kept and which are removed, and it records the reasons.
Solid wood framing with a light surface growth can sometimes be cleaned with a brush or a damp cloth and then dried. Deeper growth in wood, or growth on the plates and the sill, may need more work, and the crew explains what it finds before it does more.
Insulation and drywall are different. Once growth is in the paper or the fibers, the material is removed and replaced, because cleaning does not reach it. The crew explains this to the owner before any removal begins, so that the decision rests on what was found.
Do I need a professional mold assessment?
A professional assessment is worth asking for when growth covers a large area, is inside a wall or under a floor, or returns after cleaning. Ask for the readings and the photographs, and ask who will check the area after the work is finished.
Some owners prefer an independent check of the work, and that is a reasonable request. An assessment can be a separate visit from the cleanup, with its own record. The crew can explain what it looks for and what it would recommend, and the owner decides whether to ask for a second opinion.
Ask any company that offers mold work to show you its credentials, and check any license it names with the Louisiana State Licensing Board for Contractors, where a license applies to the work being done.
What should I do before the crew opens a wall?
Photograph the room and the area you suspect, note any smell or stain, and keep the room closed off from the rest of the house. Do not open or tear out a wall yourself, because disturbing growth spreads spores into the air.
Closing the room with the door shut and the air return sealed where you can reach it helps keep the spores in one place. Keep children, older adults and people with breathing problems out of the room until the crew has looked. Mask up if you must enter, and wash your hands and clothes after contact.
The crew uses containment for larger jobs, which means sealing an area off and keeping the air moving in a controlled direction. The method depends on the size of the area and the material, and the crew explains it before the work begins.
What does the mold work cost?
Lafayette Water Damage Restoration does not publish a price for mold work. The cost depends on the area, the depth of the growth, the materials that have to come out and the number of visits. The price is explained on site and approved before any work starts.
A price given without seeing the growth would be a guess. The crew measures the moisture, opens what needs opening, and then explains the scope and the cost factors. Nothing is removed or added to the plan without the owner's approval.
Whether an insurer pays for mold depends on the policy, and many policies limit or exclude mold. Read the policy and ask the insurer, and keep the readings and photographs from each visit, because they are the record the insurer will look at.
