Lead Testing and Removal questions, answered by experts

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.

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

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.

Professionals use specialized equipment and techniques to detect asbestos, radon, and VOCs.

If the lead paint is in a place that is not easily disturbed and is not flaking or deteriorating, you do not necessarily need to remove it. Lead is toxic when dust particles or flakes from peeling lead paint are ingested. If people are not in the area with the lead paint, it may be safe to leave it in place. You still may want to consider encapsulation with a paint formulated for covering lead-based paint, just for an added layer of protection.
