Tiger Home & Building Inspections
Tiger Home & Building Inspections
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."
