"Words cannot fully express how grateful I am to have found Biotek Environmental! Ted took a lot of time compassionately listening to my concerns and explaining the initial process over the phone. Tyler patiently shared his extensive knowledge on how mold develops along with natural ways to clean clothes and surfaces. He also explained the meter reads of mold counts and humidity levels as I tagged along from room to room during the home inspection. Every step of the process was clearly explained creating a great sense of confidence in me and Dad. Crew members Jermaine, Ray, and Matt were friendly, considerate, and diligent in their hardworking task of removing the mold source. Donna was very professional and prompt to respond to any questions by email. I could go on and on with how pleased and relieved I am to have found Tyler and company but I will just close by stating the obvious: health is vital. My elderly father's health and general quality of life have improved substantially since we hired Biotek Environmental. They are also a clean company with a generous warranty. I highly recommend them to anyone in need of a healthier home."

Lead Testing and Removal questions, answered by experts

Results from professional lead testing are typically available within a few days to a week (2-7 days), depending on factors like laboratory processing times and the volume of samples being analyzed. Expedited services may also be available for urgent situations.

Lead removal is crucial in older homes to eliminate risks of lead poisoning, which can severely affect health, particularly in children, by impacting development and cognitive functions.

Structural problems with the foundation or roof, water damage, and significant plumbing or electrical issues are all considered major red flags in a home inspection. Of these, a structural problem related to the foundation is often the most severe. Foundation repairs are typically the most expensive and intrusive to carry out, averaging around $5,000 but sometimes reaching up to $16,000. Because these problems can pose safety risks and be costly to fix, you should ask your inspector detailed questions about any identified issues. You will need to carefully consider how major problems affect what you’re willing to pay for the home, or if you want to proceed with the sale at all.

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

While not all homes built before 1978 contain lead paint, enough do, so you’ll still want to test to be on the safe side. The federal government banned lead-based paint for homes in 1978, but your state may have banned lead before that time. Around 24% of homes built between 1960 and 1977 contained lead-based paint, while 87% of homes built before 1940 contained lead-based paint.
