"Ken came out same day to remove the asbestos. He was quick and efficient with his work. He charged a great price. This is the second time I have used K&E Mold Removal and I will continue to use them in the future."

"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."

"It was apparent they were very skilled. They quickly dropped the huge limbs without a scratch on the house, fence or sheds surrounding the tree. They arrived on time and cleaned the area to my satisfaction before leaving. And they were competetively priced! I can't say enough good things about this company."

Lead Testing and Removal questions, 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.

DIY kits are available for basic air quality testing, but professional services provide more comprehensive results and recommendations. While a DIY kit may seem cost-effective, a professional assessment is more thorough. Inspectors are better equipped to catch all pollutants and hazards, and you'll still need a professional to verify and act on DIY test results. Furthermore, some kits don't test for certain pollutants or only detect their presence without measuring specific levels (like mold spores). It's generally better to opt for a detailed professional assessment.

The average cost of a lead paint inspection is about $600, but it can cost as low as $150 or as much as $800, depending on the size of the area, geographic location, and the inspection methods. Some of the most common lead paint inspection methods include:

  • Visual inspection: $150–$400

  • Paint sampling: $200–$600

  • X-ray fluorescence (XRF): $250–$700

  • Risk assessment: $300–$800

Testing typically costs between $200 and $600, depending on the number of samples and laboratory analysis.

Costs depend on the number of samples, testing method, lab fees, and whether on-site inspections are required.
