"Very easy to get an appointment on short notice when I had limited time to get a radon test done in the process of purchasing a home. Their price was also slightly lower than an estimate I'd received from another company, and the technician was more thorough about explaining the process than the other company I considered."

"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."

"The estimator examined the basement walls and identified four cracks through which water might be coming in and gave a quote.  We agreed to have the work done.  One service man came and filled the cracks in less than the estimated time.  The work involved surface patching the cracks on the inside of the wall, drilling approximately six holes through each crack and injecting a sealant into each crack.  Since we haven't had a hard rain since then, we haven't had a real test of whether it holds water out.

"Chuck asked all the right questions before giving a quote and gave us multiple options to address the problem leaks. His serviceman, Josh, was courteous and professional, clean and efficient. They filled two basement cracks with the injection sealant and we are pleased with the results. I would use them again.

Radon Detection and Reduction questions, answered by experts

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.
