"Jon came by for a consult to look at some ugly looking black staining that was growing in my basement. He was very professional and punctual and thoroughly explained why it was not mold, but harmless mildew and how to rectify it. I was so appreciative for his integrity and honesty and I will absolutely use Indoor Environmental if I ever do get mold in my house."

"We were selling our house and the radon test came back high so we needed quick and effective service. The appointment was scheduled a week from our call. The technician arrived on time and helped identify the best location for the system that was both effective and as aesthetic as possible. The install went quickly and he took the time to explain how it worked and what we should look for in terms of monitoring and maintenance. Overall, it was a good experience."

Lead Testing and Removal FAQs, answered by experts

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.

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

Some of the signs that could mean your water is contaminated, such as cloudiness or bubbliness, could also be non-problems that don’t affect your water’s potability. However, if your water smells or tastes strange, it’s a good idea to stop drinking it and test it immediately. If your well water is contaminated, the best way to discover that is to test it.

At-home lead tests can provide accurate results if used correctly, and if the kits are reputable and certified. They vary in sensitivity and methodology, influencing their accuracy. Follow instructions meticulously, ensuring proper sample collection and test execution. While they can detect elevated lead levels, for precise confirmation or if results are concerning, consider professional testing or lab analysis for comprehensive accuracy and guidance on addressing any issues.

You should ask a few questions to ensure that your potential lead removal professional is experienced and qualified to handle lead-paint abatement safely, legally, and properly.

  • What are your qualifications and experience removing lead-based paint?

  • Are you licensed and certified to remove lead-based paint?

  • How do you test for lead paint?

  • What methods do you use for lead-based paint abatement?

  • What do you plan to do with the hazardous material when you remove it from the home?

  • Do you do replacement and painting work or removal only?
