quick and courteous service

I am very thankful and appreciate the help and concern shown to me by Tim and his employees. A large piece of home siding had gotten loose and was hanging down from the backside of my house. I had called Tim's company for advice or a recommendation as I was worried an impending storm might make matters worse. Tim was kind enough to have his men stop by. His men reattached the siding and also made sure the piece was secure. Tim and his men were so very helpful and courteous in solving my problem. I'm very thankful for all their help.

VERY HAPPY With O'Sullivan!!!

O'Sullivan Installs just replaced 8 regular windows and 1 large bay window in my home. I am so thrilled with the professionalism and talent of the crew! They are meticulous with every detail, no "cutting corners", and they treated the work as if the home were their own. Tim O'Sullivan is very easy to talk with and visited the house twice to talk about the job - once before to measure the windows to be replaced and next as the new windows were being installed. REALLY glad I hired O'Sullivan Installs! Thank you! I will be getting siding soon and now I know who to hire!

Five Stars All Around

This is my third time working with Tim and his team, each project bigger. The job entailed working with another vendor for roofing and they coordinated timing. Covid didn’t help the schedule as supply was limited everywhere but Carol Ann kept me updated on the schedule close to weekly. Once we were scheduled, the crew worked like a Toyota line, following each other’s movements. Anatoli and his team onsite were respectful of the property, neighbors and my going in and out. The detail of the work from the corner trim to the bottom caps was meticulous. Another contractor for a different job commented on how well done the work was! Once the siding and trim was complete, the final details of electrical blocks, garage door seals was finished. I couldn’t be happier with the quality of the work and how amazingly different the house looks (100%+ better). The attention to detail that Tim does through his workers and himself show. I had a separate area of the front sided with ‘rock’ and they made sure that I saw what it looked like by hanging samples up so I could decide. That actually made me change my mind to the better of another color. Tim and Anatoli take constructive input seriously. From my concern of trash cleanup to sending and resending staff to finish the work properly, I appreciated being heard. I’ve recommended O’Sullivans many times and will continue to. Thanks to Tim, Anatoli, Brian, Ken and Carol Ann.
