"It all went wonderfully. We'd been lead to think that releasing would be horrible, but MKJ made it painless. They got everything done on time (tenants were expecting a baby) and passed re-inspection on first attempt. Extremely honest guy; saved us money in ways we wouldn't have thought of without compromising on outcome. Tenants are very happy with the new windows, too! Not as much communication as my husband is used to (e.g. no blow by blow updates) and not a particularly "slick" operation, but good solid trustworthy work for a very reasonable price. Glad we'll never have to delead again, but if we did it would be with MKJ!"

"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

When a surface that contains lead dust is disturbed, the dust can float about in the air for roughly an hour before settling again. Since you cannot see the dust, it is important always to wear protective gear when working with any materials that may contain lead paint and to keep children, pets, and others away from the area for as long as possible

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. 

According to the EPA, there is no safe level of lead in the blood, and so the maximum contaminant level goal (MCLG) for lead in water is zero. Even at low levels, lead is harmful to human health. It can also remain in the body and build up over time with repeated exposure.

Lead removal services typically cost between $1,000 and $5,000, depending on the extent of lead presence, the property size, and the complexity of the abatement process.

Exterior paint contains a higher level of VOCs, which can be dangerous if you’re exposed to it for a long period of time. The good news is that paint’s toxicity reduces significantly once fully dried and cured. Do not keep open exterior paint cans in your home, basement, or garage, exposing your household to harmful chemicals over time.
