"It went great. I highly recommend them. They were a pleasure to deal with. The person that came out for the estimate answered all of my questions. The estimate was fair. The work was done on schedule and with no problem. At completion, everything was explained to me. I used their electrician which worked out fine. After completion the radon test showed that my level was now undetectable."

"We hired PureTech to advise us on a real estate inspection that included a radon test. That test came back over the safety threshold. After meeting with Zach C, he advised us to make some repairs in the basement and to schedule a retest. We did and the results speak for themselves; the levels came back well into the safe zone. I couldn't be more pleased with the recommendations made by PureTech and Zach C specifically. Saved us a bundle in what could have been a nightmare, and now the sale of our home can proceed. Thank you PureTech!"

"We were looking for a next-day inspection, and House Detective was the first firm to respond to the emails we sent out. Because we weren’t working off a referral, we didn’t know what to expect, but Kevin exceeded our expectations! He arrived on time, provided an overview of the inspection plan, highlighted the issues he’d be highlighting in his report during the inspection and generally inspired confidence. Although the firm charges a flat rate for inspections, Kevin spent an hour longer than planned with us, answering all of our questions. We were incredibly lucky to have chosen House Detective and will definitely recommend Kevin to our friends!"

"The Gaidish crew arrived early and completed all work in three days. They attached a plastic film around the perimeter of my basement to minimize dust and did a wonderful job cleaning up. We've had some heavy rains since then and my basement was dry for the first time in many years. Although I was completely satisfied with the work, I was most impressed with the time the owner Jeff took to answer some questions. I had stopped by the Gaidish office on a Saturday morning and although Jeff had already left, someone called him and he returned, opened the office and he proceeded to answer my questions. I certainly wasn't expecting that! These are the people you want working on your foundation/Basement problems. You won't be disappointed!"

"I used this company for my furnace/central air cleaning and they were very professional as well as for this job.  Mike arrived on scene and suggested some things to me and got the job done within an hour.  I will use them again in the future.

FAQs for radon detection and reduction projects in Wales, WI

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.
