"H&G is fantastic - extremely professional, timely, and by far the best bang for your buck. I was able to talk directly to the owner and easily schedule an emergency appointment for that same day. Mr. Garvin himself came out the the property to locate and treat standing water and mold in our crawl space and kitchen and conduct an air quality test. He worked hard and quickly to identify and fix the issue, didnâ t overcharge for anything unneeded, and even took the time to be sure we understood exactly what he was doing. Overall I appreciated their urgency, care and precision. Iâ ll be using H&G from now on!"

"I was very pleased with the service and work done by SWAT environmental. Lance was very helpful in explaining the process when he booked my appointment and the two techs who installed the radon remediation system were professional and courteous. The system itself isn't inconspicuous but I feel safer knowing that our radon levels are significantly lower now."

"I had a pipe burst in the basement of our rental property, Flood Crew was referred by our realtor. They arrived quickly after the pipe was fixed by our plumber, demoed, and dried out the areas, even handled packing out our furniture and placing carefully in a pod storage while the work was being done. They did mold testing and made sure everything was safe, the best part was that they dealt with the insurance and we didn’t have to do anything."
