"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."

We're BBB Accredited and for the past three years have been awarded the BBB Certificate of Customer Satisfaction and Excellence! Our mold inspections evaluate both external and internal conditions of your property and identify when there is mold.

Our inspections also identify conditions that could cause mold in the future and can save thousands on expensive remediations. In the event of a small mold contamination, we can remediate to return the area to a pre-mold healthy condition. For larger remediations, we can refer you to a number of excellent remediation companies that we work with. Our radon measurements use state of the art CRM's (Continuous Radon Monitor) that provide important data on radon levels within the environment.

"Our 60+ year old well tank started to leak (original to house, used only for outside watering). Eric came to price out the replacement of the tank. Because we have an existing bleeder system, the newer tanks with bladders were not a fit. Eric took extra time to assess our situation to make sure we got the right tank kind and size for our needs. We very much appreciate the extra time he took to "get it right" and to explain things to us. He was later able to return, replace our tank and remove our very old and large tank. We value his attention to detail and patience, and we appreciate that as this is his business, he takes pride in his reputation. We would definitely recommend his company to others."

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."
