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!

I am very pleased with the work completed by Granahan Construction. The process was completed quickly and the entire team was professional, and polite and a pleasure to have in our home.

Our home has 2 newer apartments attached but we designed the upstairs apartment with wood floors. When our tenant could not take the echoing noise from above, we contacted Granahan Construction. He provided us with studio quality soundproofing,while the price intially seemed high, It saved us from loosing our tenant and the mortgage.

Thanks to the entire crew at Granahan Construction for the fabulous soundproofing job they did in the master bedroom of our condo. Courteous , professional and efficient. Every day the work area was cleaned before they left and on the final day the room was back to normal.

Great experience with Granahan Construction. John worked around our schedule to come out and give us an estimate after making an assessment of our noise issues. Work began a couple of days later and I must say we were very impressed with how clean they kept the work area during the entire process. All work was completed quickly and we could not be happier.

Thanks to Granahan Construction I have slept like a baby for the last three nights- this is something that has not happened in many years. I don't have to get up when my neighbors are getting ready for work. My sleep is not disturbed at random hours of the night. I even took a nap yesterday afternoon! My dogs are no longer neurotic and traumitized by the booming and creaking from upstairs. They are miracle workers!

Professional and friendly, did an excellent job with the soundproofing.

John and his crew were able to finish the job in a week like we were quoted. It was nice to get a follow up call to make sure we were happy and we are!
