"We contacted Sherlock's because my daughter tested high for lead.  We rushed to find a company to help us identify where the contamination was coming from.  I found Sherlock through google and had the best first impression of them than from the other companies I called.

Sally explained the process of lead testing our home clearly.  They performed the lead test less than 2 days from when I called them.  Sally and Chuck came to our home together and tested inside and out for 2 hours.  In the end, we found no source of lead contamination at our home (meaning it must be coming from an outside source).  They provided a thorough report and the price was reasonable.  They are also easy to get a hold of.

Since having them perform the testing, I have heard other positive reviews of this company.  And I will recommend them to anyone who is unfortunate enough to have a poor blood lead score.

I will also never buy a new home without them inspecting it first."

Lead Testing and Removal FAQs, answered by experts

Hiring a professional for mold and toxic material testing ensures precise identification of harmful substances within a home. Professionals utilize specialized equipment and techniques, providing accurate results that inform proper removal strategies, safeguarding occupant health.

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.

Avoid disturbing suspected lead-containing materials and follow professional guidance on sample collection.

Lead exposure poses significant health risks, including neurological, developmental, and behavioral disorders, especially critical in young children and fetuses.

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.
