Tiger Group, Inc. is a Connecticut family owned business providing Inspection Services since 1992. We are licensed and insured. Our 22 highly trained and specialized inspectors provide thorough Residential and Commercial Inspections throughout CT, Western MA, and Westchester, NY. Additionally, we provide Radon and Well Water Testing, and Mold Assessments. We inspect 7 days/week. We look forward to the opportunity to work with you.

"This review is from a seller where an inspection was performed. The heat was not shut off after the inspection and my family and I walked into 90 degree temperatures because the heat was never turned off when the inspection was complete and it was on for 7 hours until we got home. In addition the mud room has a thermostat and electric heater and that was also left on high which we did not realize until the next day. In addition, to prove a point to a potential buyer he forced a hole through the wood in our detached garage reporting that there are signs of water damage. The garage is from 1930, there has been water in the garage especially when we had the hurricane last year but they could have just written that in the report not damage our property to prove a point. Coincidentally, the same inspector came back with another interested buyer and yet another piece of wood was pulled off from the garage. If that is not bad enough, the same inspector gave confidential information from a previous inspection to a new potential buyer which led to another buyer terminating the deal. I know this as our lawyer communicated with the potential buyers attorney and said that the inspector passed on information about a previous inspection he did at our house a week earlier.. in addition, our neighbor and friends were outside during the outside portion of the inspection and they heard the inspector give the potential buyers and their real estate broker information about the last inspection and what the other potential buyers said. So much for confidentiality."

Radon Detection and Reduction questions, answered by experts

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

A radon test has no effect on humans—only the radon in the air does. The test does not redistribute the radon that is already present so yes, it’s safe to be around the testing kit even if it isn’t safe to be in the room itself. The test absorbs and measures the radon, but doesn't absorb enough of it to make the room any safer.

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.

The only way to determine if you have a radon problem in your home is to have professional testing done. You can buy DIY radon test kits, but these are sometimes inaccurate in certain temperatures and humidity levels, and they don’t paint the entire picture in terms of your radon exposure. Scheduling testing once every two to five years is best. You can also look out for the following symptoms, which, according to the American Cancer Society, are symptoms of radon exposure:

  • Shortness of breath

  • Cough

  • Tightness in the chest

  • Difficulty swallowing

  • Hoarseness

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.
