"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

Soil, Water & Air Technologies provides solutions to customers in need of vapor intrusion services. We custom design sub slab depressurization systems to effectively mitigate radon gas, TCE, petroleum vapors, and various other VOC's. Most real estate transactions, financing and/or re-financing activities require an environmental review which includes air quality testing. Our experienced office staff understands the need for quick, complete, and accurate information in order to provide solutions so transactions are not put at risk. We offer detailed upfront pricing, best in class warranties, and proudly offer discounts to senior citizens, service members and repeat customers.

"Be careful. I called to have a radon mitigation system installed and the sales rep on the phone took down the information and scheduled the appointment. I was upfront about an interior drain being installed. When the technician arrived, he said he'd be happy to install the system, but that it would be worthless because of the interior drainage system. I then received a $200 invoice for the site visit. Frustrating scenario to have a sales rep schedule the appointment, knowing full-well that I had an interior drain, and then the technician tell me there's no point to install a mitigation system, but then charge me for the inconvenience of it all."

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

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

Properties should ideally be tested for radon every 2 to 5 years or sooner when changes to the property structure or ventilation occur that might impact airflow.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

Avoid opening windows and keep doors closed during testing to obtain accurate readings.
