"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

While home mold tests can provide a simple identification of mold presence, they lack accuracy and reliability. These kits may detect mold spores but can't pinpoint the source or identify the type. Professional testing, combined with an inspection, is more comprehensive and leads to actionable next steps. 

Mold is a blight on your home but over time, can be an extreme health risk, especially for immunocompromised individuals. Depending on the type of mold you’re dealing with, you could even experience neurological symptoms, or in extreme cases, you can be hospitalized. Even a tiny speck of toxigenic mold can cause a whole slew of very serious health issues. Deal with any mold issues immediately. 

Knowing what to expect during a mold inspection can help make the process easier. Prepare by closing doors and windows for 48 hours, turning off HVAC systems for at least two hours, and avoiding disinfectant chemicals for at least 48 hours. 

The mold inspection process takes between 24 and 48 hours. Your professional will check walls, fireplaces, air ducts, vents, and windows for visible spores. They will also take an outdoor base air sample. Your pro will send these samples to a lab for testing and advise you on the findings.

If you’re unsure whether you have mildew or mold, you can hire a professional to test the material. The mold inspection cost can range from about $300 to $1,000, depending on the size of the growth area. Once the testing professional tells you whether you have mold or mildew, you can then take the necessary steps to get rid of it.

Black mold on wood is a very serious issue. Besides compromising the structural integrity of the wood, it poses significant health risks. Stachybotrys chartarum, commonly known as toxic black mold, produces mycotoxins that can lead to respiratory issues, allergies, skin irritations, and other health problems. If left untreated, it can spread rapidly and compromise the structural stability of the affected wooden structures. Immediate remediation and preventive measures are essential to mitigate the risks associated with black mold on wood.
