The workmanship was inconsistant at best. Some of the work was done well, yet there were quite a few costly mistakes and poor follow through. Though the owner of the company initially promised customer satisfaction and agreed to take responsibility for the mistakes made (resulting in going way over the timeline for completion and increasing costs considerably for me) he ended up going back on his word. The experience of working with Gannon Construction was extremly frustrating and disappointing.

GCI was a life saver. We did a massive remodel including a kitchen/family room/basement (the entire back of the home) bump out along with a master bedroom/bathroom put in above the garage. We encountered multiple unexpected developments including an unmarked underground stream, County bureaucratic delays, and an unexpected change in the terms of our home equity line that was being used to finance the project. GCI came up with solutions each time we had a problem.--my wife and I recommend them highly.
