"Cal Coast communication through the whole process was what I needed. I didnâ t know the questions I should ask. I was scared and nervous. Iâ ve never been through this before. Cal Coast took care of everything and problem solved for me throughout the whole process. Not only did he do the water mitigation and mold removal, I hired him to do the put back as well. Everything was done on time. I highly recommend them."

"We were getting our house ready to put on the market when we found mold in the crawl space and one of the closets. MacCraft came out the same day we called— Alex walked us through exactly what needed to happen, gave us an estimate, and got it handled. They documented everything so we had paperwork to show buyers. House passed inspection without any issues. Highly recommend them"

Mold Testing and Remediation FAQs, answered by experts

Wood stain is not considered toxic after it dries. The solvents in wood stain are what give off volatile organic compounds (VOCs), which are toxic, but these dissolve as the product dries, leaving behind a non-toxic product. When working with wood stain, you should always wear a respirator and rubber gloves to protect yourself, but once it dries fully, it’s not toxic, according to the manufacturer’s instructions.

Mold is not guaranteed to grow on wet drywall, but the risk increases significantly the longer the material remains wet. Mold and mildew can begin to grow in as little as 24 to 48 hours, especially in optimal conditions, which include moist, dark places with temperatures between 77 and 86 degrees Fahrenheit. If the drywall is too wet to dry within that timeframe, mold can grow and spread. In any instance of water damage, it is wise to get a mold inspection to be certain that none has taken up residence in your home.

The high humidity of steam showers creates the ideal environment for mold growth, so it’s important to stay proactive against it. Along with regular cleaning, run your bathroom fan during and after your steam shower. Keep your shower door open and any doors and windows in the bathroom to allow the space to air out properly. If you come across ugly mold spores, spray them with undiluted vinegar, let it sit for at least an hour, and then scrub away the mold.

Dog vomit slime mold is not toxic to humans, plants or pets. However, it can act as an allergen to people with allergies. Dog vomit slime mold is considered more of a cosmetic nuisance. However, it is beneficial to its ecosystem as it helps break down organic matter, releasing nutrients for plants.

Beyond looking for visible signs of mold in a home, you can tell if your house has mold by undertaking testing. You can hire a local mold testing company to run the test for you, giving you a sure answer. Professional testing is often the best way to determine whether you have mold, as some types of mold may grow in places where you can’t easily see them, such as behind walls.
