"This contractor was excellent. He took his time and did the job right. He filled all holes and crack, took his time doing proper prep work, which is the base for having any project turn out looking good. He was courteous and professional . He is a 5 star out of five star. If there are problems that were hidden and come to light he will assess them, make you aware of them and fix them. I highly reccomend his service."

"The basement king was a pleasure to work with. His knowledge is unmatched in the Texas area for sure. I received multiple quotes and talked to multiple companies and he was the best. He's passionate about his work and the manner in which it's done. If he says something, it happens. An added benefit was their cleanliness. Usually a job site of this size and complexity is a mess, but not with the basement kings. 10/10!"

Mold Testing and Remediation FAQs, answered by experts

Pressure-treated wood offers some protection from the elements but doesn’t protect against mold. However, if you spot mold growing on pressure-treated wood, it doesn’t indicate rot or an interior fungal infection—the treatment process ensures that the mold stays on the exterior. Keep the wood dry, but if you spot some mold, remove it immediately and clean the area.

Mold is very likely if you do not take action to fully dry your home within around 24 to 48 hours after water damage occurs. This can happen even faster in warm, dark locations with extensive water damage. In areas of the home that receive ample sunlight and only have slight moisture issues, it can take weeks for mold to appear.

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

Dehumidifiers do not directly remove mold or spores from the air. However, by lowering the room’s humidity, spores are less likely to flourish when landing on surfaces.

If dresser drawers are damp or dirty, they could be transferring odors to your clothes. Make sure to only store clean, dry clothes in dresser drawers. Plan to thoroughly clean out the drawer interiors at least two times per year.
