"Major project was installation of a radon remediation system."

"Ryan was great! I had some hesitations about radon mitigation in an older home and Ryan assured me it would be no problem. He was honest and straight forward with how to tackle the issue, and didn’t hard sell on doing every possible thing, but made his suggestion to try the mitigation system, then seeing where the levels tested to determine if next steps were necessary. He did great clean work and was priced well. I appreciate his hard work to make my new home safe."

"Easy to work with, fair and honest."

With years of experience in HVAC, plumbing, electrical, and general contracting, we entered the radon industry when we saw a lack of quality. We design every system specific to your home with quality and longevity in mind. Many competitors have a focus on money and speed, we focus on quality and efficiency.

"I called because a listing tested high for Radon. They were prompt & very considerate to seller."

"Radon gas in my house’s lower level was 3.6 picocuries per liter: below 4.0 pCi/L, at which EPA urges remediation, but high enough that it’s recommended. Beginning a week after SWAT installed gas elimination system (for $850), radon level dropped to 0.3 pCi/L: about the same amount of radon as is found in fresh air. Nuff said."

"I hired Double Check to do an inspection for a personal decision of "Repair or Replace". Justin came out, performed the inspection, took photographs and answered all my questions. He found some issues like a few shingles missing, popped nailheads and the like. We discussed the Repair or Replace decision. Very knowledgeable and easy to deal with. Highly recommended."

"I had a hard time contacting this company at first but when they finally responded, the service was great. Chuck met with me and explained what he thought would work best for the crawlspace in our new home. We originally wanted to install drain tile to avoid any possible water seepage in the future but he told us it wasn't necessary. Unlike PermaSeal who tried to sell us everything under their roof! Buyer beware of PermaSeal! Anyway, Chuck offered to provide a payment plan since we couldn't afford it all in one lump sum. We had a few issues at the beginning with things unrelated to them but Chuck was very responsive and advised us regarding some issues with our village permit. Even though we called and e-mailed him several times in one day, he maintained his great customer service. We finally scheduled an appointment and then had to re-schedule which they accommodated. The day they showed up, they came a bit late but Chuck sent a message letting us know. He showed up to check out the installation as well and warn us of the strong smell of the foam to see if we wanted to leave the house. We stayed but the foam smell was very strong for a few weeks and even up to today, we have not used it yet due to the smell. We may not end up using the crawlspace for storage as originally planned because we've noticed there's still a lot of insects getting through there since we left the entrance open for the smell to dissipate. Well, the crawlspace looks good and we are very happy that they installed a light switch by the entrance and a bulb in the middle so we could see the entire space if we want to go in there. We also got excited when Chuck mentioned they would do a radon test to show us the difference with the insulation. This has not been done yet but I hope they still come out and do it. I really enjoyed working with Chuck. He is a great guy and I highly recommend using this company. Stay away from PermaSeal! I say this because they tried to take advantage of us prior to us contacting this company."

"Very professional and very satisfied with the service provided"

"Excellent. The inspector was very thorough, and identified numerous concerns that we hadn't noticed ourselves. Thank you!"
