"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

Some causes of brown well water—like excess tannins or dissolved iron—don’t pose a health risk. In other cases, harmful bacteria might be the culprit. If your well water has suddenly turned brown, it’s a good idea to use a home water test kit to get a better sense of what’s going on with your water. Consider calling a professional for an expert opinion before drinking the water and hoping for the best.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

No, you can’t place hazardous waste in a dumpster unless you specifically ordered a dumpster for hazardous waste removal. If the dumpster company finds hazardous waste that it didn’t approve for dumping, the company will return the waste to you, and you’ll likely face a fine for illegal dumping.

You can paint over lead paint, or “encapsulate” it with a special paint that includes an ingredient called an encapsulant. The EPA approves encapsulation as a lead paint removal method as long as the paint remains undisturbed. Standard types of paint without an “encapsulant” from the big box stores or hardware stores do not meet EPA standards for remediation of lead-based paint.
