"They did a good job. They came out pretty much when they say they would and they did get it done. I found them from Angie's List and they have a lot of good reviews but the thing that I didn't like was he said that it would only take like a day or two and it sounds like he didn't communicate well. The first time I called they didn't call me back and I tried to contacted them through the e-mail from Angie's List and the owner that comes checked that out really quick. So he came, he check and saw that I e-mailed and I talked to one of his workers between that. He got right back to me as soon as he got involved. He got the estimate and we talked about the job. They came out here and they ended up working week and what it sounds like was however he delegated the job, he didn't delegate enough people for the job that needed to get done. It rained when they are in the middle of working and they covered my porch roof but it leaked a little bit. It didn't turn out that anything was really injured, they really felt sorry about that and offered to do anything that I needed to to make it right. I got my job done and got it done well but there were definitely some glitches. They cleaned up nicely. The employees were nice and the employee that was on site felt terrible, he felt that it was taking so long for it to go through, he felt that he must calculated and I guess what happened was he had ordered the roofing for the porch and it was suppose to be delivered but our delivery time was off. He felt like it can get it done before the rain comes but then because it wasn't delivered on time he was not able to do that and got into trouble. Then the owner came out to find out what was going on, he's going 'Oh my God, we really didn't put enough people on this job which the guy actually out here didn't say all along', but generally they were professional group and they know what they were doing."

"Very knowledgeable and thorough inspector. I HIGHLY recommend 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.
