Mold spores are present in nearly every home in America. Mold causes allergies, asthma, and other health issues. Our certified mold inspectors can help you discover what's causing mold growth in your home, and help to make sure it doesn't return.


Lead poisoning remains the #1 preventable childhood disease in the United States. Most parents don't know that a speck of lead dust, as small as a grain of sand, is enough to poison a child. If you live in a home built before 1978, you are likely to release lead dust every time you open a window. Before you renovate, always conduct a lead inspection.


Dangerous asbestos fibers are too small to be visible. But, once inhaled, they lodge in the lungs forever. Many older homes have asbestos in roofing and siding, textured paint, patching compounds, vinyl floor tiles, insulation, and other building materials. Our certified asbestos inspectors can pinpoint where asbestos may present a danger in residential and commercial buildings.

RTK mold lead testing

Not all environmental testing companies are alike. Some, like RTK, restrict their business to only environmental testing, while others are “one-stop shops” that do both testing and remediation. What’s the difference? An independent, certified testing-only service has no incentive to magnify the problem and increase profits through remediation services. RTK’s pledge is to do right by our customers, and make sure you have accurate, unbiased information you need to make educated decisions. Read more
