Knowledgeable, professional, and and quite good at their jobs. Everyone was polite, mindful of what needs to happen with social distancing, but also more then willing to explain everything they were doing. I would highly recommend CT Basement!

They were wonderful to deal with, quick to return phone calls. The crew was courteous, and efficient. The Radon system worked and we went from a rating of 7 to a rating of 2. So I am very happy with the product.

They scheduled an appointment and came out to the house quickly, even during the pandemic. They replaced the radon fan at a fair price. Definitely recommend them!

I called them in for radon ventilation services. They gave me a certain plan to install the system a certain way. I paid them a deposit and scheduled the service. When they came in, their team wanted to drill my concrete floor and close a certain drain, which was completely different than the plan they had marketed to me before. I didn&amp;#39;t allow them to start their work and sent them away, and I asked for my deposit back. They wouldn&amp;#39;t agree to give the deposit back. They wouldn&amp;#39;t even answer my letters... I sued in small claims court. They didn&amp;#39;t even answer. I won the suit. They didn&amp;#39;t pay. I had to use a Marshall&amp;#39;s help to get my money back. Don&amp;#39;t EVER use these guys. I deal with 30 vendors for my house. These guys are an outstanding group (to the negative).
Response by Connecticut Basement Systems Radon, Inc.: It is unfortunate that Mr. Medina chose to give a negative review and attempted to tarnish our reputation. There is more to this story than can be posted here. For the record, our refund check was in fact returned to us. We are the oldest radon mitigation contractor in CT (1987), with tens of thousands of successful mitigations and satisfied customers. We are a team of qualified radon industry professionals that takes pride in the work we do, and the services we provide. Our longevity in this industry is a testament to this.

Review by in Carmel, NY
I was so impressed with the level of communication between the company and its customer. I had to contact them many times due to problems with my water and the requests of my buyers inspector. My calls were returned promptly by all involved. They have a professional and qualified staff
Response by Connecticut Basement Systems Radon, Inc.: My apologies on the late response to this review...I really appreciate you having taken the time!

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
