"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."

"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."

If radon is present in your home, you can expect to pay around $1,000 for a radon mitigation system or between $780 and $1,250 in most cases. The exact price will depend on the severity of the radon leak, home size, and the protocol the radon specialist develops to remove radon from your home and keep it out. Your foundation type will also affect your radon mitigation system cost, as unfinished basements will cost about $4,600 to seal and ventilate, while crawl spaces without a foundation slab may need extra encapsulation, costing $1,500 to $15,000.
You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional.
Radon testing costs depend on whether you hire a professional radon inspector or DIY test. You can expect to pay $150 to $800 to hire a local radon inspector, and home-testing kits range in price from $15 to $250 from home improvement stores. However, it’s best to trust a professional inspector with this task to ensure accurate results. Plus, if you have radon in your home, your testing company can develop a mitigation protocol to keep you and your family safe from the dangerous gas, so it’s well worth the money to hire a professional.
Yes, radon testing is absolutely necessary if you suspect the presence of this hazardous gas, and the Environmental Protection Agency (EPA) recommends testing for all homes in the country. Radon is a pervasive natural gas that can leak through your home’s foundation and seep into the living areas. Unfortunately, the gas is highly carcinogenic and is the second leading cause of lung cancer. Radon testing is crucial for keeping you and your family safe from harm, so hire a radon mitigation specialist to test your home if you suspect its presence in your home.
In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.
