"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."

Water Fire Fix, LLC
Water Fire Fix, LLC
Our family owned business provides professional, eco-friendly cleanup and restoration services throughout Connecticut. We specialize in residential and commercial damage due to water, fire, mold, and natural disaster.
"Tim was wonderful. I put in this project on a Saturday night after finding mold behind a piece of furniture in my finished basement. The next morning Tim already reached out looking to set up an appointment Monday morning. Over the phone he explained the possible process of this project and put me in the books first thing Monday morning. He arrived right on time, looked at the area, and again explained everything. After about 15 minutes of doing his inspection, Tim gave me two estimates, which were both fairly priced. I selected the estimate that worked best for me, and Tim got working right away. Throughout the project, he continued to update me with what he was doing and what he had left. From when Tim arrived to when he left, it took him roughly 3.5 hours for the whole project. He did an excellent job, and I would recommend him to anyone."
