Our Promise: No Conflict of Interest


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. We don’t bait you with “free testing”, and have nothing to gain financially by inventing problems in your home or business, therefore can potentially save you thousands on unnecessary repairs. 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.
