"Mat is the inspector realtors hate... tongue-in-cheek. He is extremely knowledgeable, has great attention to detail, and is very honest. If there is something wrong with the property, you better believe he's going to find it. He takes the time and does a thorough job. I highly recommend him!"

"This is a high quality mold/fungi/fungus testing company, with excellent customer service and follow-up. The phones were picked up on the first call each time, and arranging for an appointment was very easy. They arrived on time, were efficient, informing, and friendly in their work, and brought commercial equipment to perform the test samples. The follow up phone call and email on the test results was good, and they provided a potential remediation plan for us to follow on the test results. The third party lab utilized by them had easy to understand numbers, graphs, and descriptions of what was tested. We will do business with Gardner Services again in the near future, and will recommend them to others."

"Nick contacted me almost immediately after scheduling my initial appointment through home advisor. He was timely with his appointments, professional during his conversations, and he worked efficiently during the project itself. I love that his work has a transferable written guarantee!!! His prices are competative, and his work is great. I would highly recommend him to anyone that needs to mitigate their home for radon gas."

"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."

"When we bought this house we were planning to renovate the basement.  The previous owner had represented that it had never taken on water.  The first weekend we were here, however, a torrential rainstorm caused the basement to flood.  We realized we needed to waterproof it before we could do anything else, and decided that drain tiling was the safest way to go.
Greg was phenomenally responsive from the start.  He was very clear about what needed to be done and how they would do it.  He also described some optional work but was explicit that it was optional and if it didn't fit within our budget that was that, and he wasn't going to push it the slightest bit.  His quote blew away the bigger, well-known firm and was less than or on a par with some others.  He also agreed to demo the walls for a slight extra charge, which otherwise would have been a huge convenience for us.  Between then and the start of work I emailed him repeatedly with various questions and he responded almost instantly.  When his workers took down the paneling we got the unpleasant news that we had huge cracks in the walls that would need to be tuckpointed and in one area a big chunk of foundation was jutting from the wall.  That section of the foundation would need to be replaced and a support beam installed.  We were more or less at Greg's mercy at this point -- we weren't going to halt work and bring in a series of guys to quote the tuckpointing & repair -- but Greg gave us an estimate of $2,600-$3,000.  We can't know for sure, but suspect that this price was more than fair, and Greg stuck to it even though we think the work turned out to be more than they expected.
The project manager, Jim, was fantastic to work with throughout, very communicative and accomodating, and the crew of five guys or so was extremely friendly and professional.  All in all, A Perfect Crawlspace was a pleasure to work with and we could not be happier with the results.

Radon Detection and Reduction questions, answered by experts

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.
