I have to thank John and his crew for going out of the way to finish the work on our rental. We had a very short time frame to get the project completed before a tenant moved in and the were able to accomodate us. The fionished project is wonderful and I am sure the new tenant will not have any issues with noise from the adjoined apartment.

Thank to everyone at Granahan Construction from the owner to the techs that did the install, that life is much more quiet now. The noise reduction is incredible, I truly did not expect as much reduction in the noise from the neighbors. I could not be more satisfied.

John did exactly what he said he was going to do and within the time frame he gave us. The work was done professionally and he is very conscientious about his work. He even did some touch up painting that was not paid for in the bid because he wanted us to be happy with the end result!
