[GET ESTIMATED NOW](https://maingreenconstruction.com/contact-us/) ## What mold remediation includes One team from the first test to the finished wall Wiping mold off a wall is cleaning. Remediation means removing what the mold has damaged, stopping the water that fed it, and putting the room back together. ### **Inspection and testing** We look for the moisture as much as the mold: under sinks, behind tubs and showers, around windows, in the attic and along slab floors. Samples go to licensed and certified labs when the spread is unclear or older materials may also hold asbestos. ### **Safe removal** Moldy drywall, insulation and carpet are removed, not painted over. The EPA notes that absorbent materials such as ceiling tiles and carpet may have to be thrown away once they are moldy, and that mold on hard surfaces can be scrubbed off and the surface dried completely. ### **The source, fixed** A leaking pipe, a failed shower pan, a roof leak or a bathroom with no working exhaust fan is repaired as part of the same job, since Maingreen also does [plumbing](https://maingreenconstruction.com/plumbing/) and [roofing](https://maingreenconstruction.com/roofing-contractor-los-angeles-ca/). Stopping the water is what lowers the chance of mold coming back. ### **Rebuild** New drywall, insulation, flooring, tile or cabinets go back in, finished to match the room. If you were already planning a [bathroom](https://maingreenconstruction.com/bathrooms/) or [kitchen](https://maingreenconstruction.com/kitchens/) remodel, the rebuild can become that remodel. ## Signs you have a mold problem - A musty smell that stays after you air the room out. - Dark or fuzzy spots that come back after you clean them. - Stains on a ceiling under a bathroom, an AC unit or the roof. - Paint that bubbles or peels, or drywall that feels soft. - Water on window sills every morning, or a bathroom mirror that never clears. - Any leak, overflow or flood that was not dried out within a day or two.

The EPA says that if the moldy area is less than about 10 square feet, roughly a 3 by 3 foot patch, in most cases you can handle the job yourself. Small spots on tile grout or a window frame usually fall in that group. Call a professional when the patch is bigger, when it keeps coming back, when it is inside a wall or ceiling, or when the water came from a sewer backup. The EPA also warns not to run the HVAC system if you suspect it is contaminated with mold, because it can spread mold through the house. **Before you scrub:** in an older home, do not sand or tear out walls, ceilings or vinyl flooring yourself. The EPA lists textured paint, patching compounds and vinyl floor tiles among the materials that may contain asbestos. We test for both, and [old insulation](https://maingreenconstruction.com/insulation/) can be tested before it comes out. ## Why mold comes back, and how we stop it Mold needs water. The EPA's own summary is that the key to mold control is moisture control, and it advises drying water-damaged areas and items within 24 to 48 hours to prevent mold growth. Remove the mold without stopping the water and it is likely to return. Common sources of that water: - PlumbingSlow leaks under sinks and behind toilets, failed shower pans, and pinhole or slab leaks that stay hidden inside walls and floors. - RoofsA leak around flashing, vents or skylights that wets the attic insulation before any stain shows on the ceiling. - VentilationBathrooms with no exhaust fan or one that vents into the attic, and attics that trap warm, damp air. - After a flood or overflowCarpet, pad and the bottom of drywall that were left to dry on their own (see [water damage restoration](https://maingreenconstruction.com/water-damage-restoration/)). Because Maingreen also does [plumbing](https://maingreenconstruction.com/plumbing/), [roofing](https://maingreenconstruction.com/roofing-contractor-los-angeles-ca/) and remodeling, the repair that stops the water is part of the same job, not a second contractor you have to find. ## Questions to ask any mold contractor Whoever you hire, these answers tell you how the job will be done: - Where is the water coming from, and who fixes it?If nobody repairs the source, the mold is likely to return. - How will the work area be closed off from the rest of the home?Ask how the room is sealed off from the rest of the home and how the air is handled while the work goes on. - What comes out, and what is cleaned?Ask for the materials that will be removed as a list, so you can compare estimates line by line. - Will anything be tested first?Mold testing helps when the mold is hidden; in an older home, ask whether the walls or flooring should be tested for asbestos before they are opened. - How will I know it is done?You can hire an independent inspector to check the area before the walls are closed. Ask whether the schedule leaves room for that. ## What sets the cost and the timeline The mold assessment and the estimate are free: one of our licensed asbestos and mold inspectors comes to your home first, because two jobs that look alike from the outside can be very different inside the wall. These are the things that move the price and the schedule, so you can compare estimates on the same terms: - How far it has spreadA spot on the surface is a small job. Mold that has reached the back of the drywall, the insulation or the framing means more material comes out and goes back in. - What it is growing onTile and glass clean up. Drywall, carpet and insulation are replaced. - Where it isAttics, crawl spaces and the space under a slab take more setup and protection than an open bathroom wall. - The repair behind itA new shut-off valve is quick. A repipe, a new shower pan or a roof repair is its own piece of work and is priced as such. - Drying timeWet framing and subfloor have to dry before the room is closed up again; the EPA advises drying water-damaged areas within 24 to 48 hours to prevent mold growth. - TestingLab testing for mold or asbestos is added when the extent is unclear or the materials are old enough to need it. - The finish you wantPutting back what was there costs less than upgrading the room while the walls are open. Ask for the inspection findings, the scope of removal and the repair of the source as separate lines, so you can see exactly what you are paying for.

Who should I call?If the patch is small and on tile or grout, you can usually clean it yourself. If it is larger than about 10 square feet, keeps coming back, or is on the ceiling or inside the wall, call a contractor who can remove the damaged material and fix the leak or ventilation problem behind it. That is the work we do in Los Angeles homes, along with the rebuild.Is black mold more dangerous than other mold?Not by color alone. The EPA guidance is the same for every kind of mold you can see: in most cases, if visible mold growth is present, sampling is unnecessary; the mold is cleaned up or removed and the moisture problem is fixed. If someone in the home has health concerns, talk to a doctor.Do I need mold testing before removal?Not always. When the mold is visible and the cause is clear, the work can be scoped from an inspection. Testing helps when you smell mold but cannot see it, when you need to know how far it has spread, and in older homes where the walls, ceilings or flooring may contain asbestos. We work with licensed and certified labs for both.Does homeowners insurance cover mold in California?It depends on your policy and on what caused the water. Read the mold and water damage sections of your policy, call your insurer before the damaged material is thrown away, and take photos of the mold and the leak first.How long does mold remediation take?It depends on how much material has to come out, whether the moisture source needs a plumbing or roof repair first, how long the area takes to dry, and how much has to be rebuilt. The EPA advises drying water-damaged areas within 24 to 48 hours to prevent mold growth, so plan for a drying step before the walls are closed. After the inspection, ask for the steps in order.Can you fix the leak and rebuild the wall too?Yes.
