"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

Unfortunately, lead dust does not look different from any other type of dust. You cannot detect it with the naked eye. To determine if you have lead dust in your home, you will need to hire a local company to take a sample from the paint and test it for you in a lab.

Several different measurements may be used to determine the amount of lead in water. The most common unit of measurement is micrograms per liter (µg/L), which is the same as parts per billion. Another measurement is milligrams per liter (mg/L), which is the same as parts per million.

With regular testing, treatment, and maintenance, water from a community well should be safe to drink. Unfortunately, the EPA does not regulate private wells, and contamination can happen. 

If you have doubts about the quality and safety of your drinking water, you have options for testing. You can pick up kits from your local home supply store or harvest samples and send them to a local testing facility. To get the most complete water quality testing and system diagnosis, seek a local well professional. They know what to test for and can recommend and implement a longer-lasting solution.

If lead is detected in a property, steps should include arranging for professional removal or containment, notifying all occupants, and implementing interim safety measures to reduce exposure.

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