O'Sullivan Installs

Recently had windows installed. Excellent experience. Brian, Estaban, Dan and Christina all knowledgeable and professional. Also very present, down to earth and good listeners. Five stars for sure.

We’ve used them on 3 separate occasions. For our windows, doors, and most recently siding. Great experience each time.

After using O'Sullivan Installs to replace our front door, two years later we had had them back to add a storm door and most recently they replaced windows in our house. Their quality and workmanship is top notch and I have referred them to at least 3 or 4 people who need windows and doors. They do quality work and you can tell by their craftsmanship that they care about what they do and take the time to install things correctly and also come back to check on things if you have any issues. When the building inspector came to close out our permit, he said they also did a good job. I bet he sees a lot of bad work! They clean up after themselves and leave no mess behind. I am so happy with our new windows and when we need the rest of our windows done, I know who I am calling!

Initial Disclaimer: I did not have any actual work performed by O'Sullivan Installs. I contacted them about getting a quote for replacing a storm door for my house. While I did not have O'Sullivan Installs perform any work for me the conversation I had with the company over the phone was enough to give me an idea of what working with the company would be like. The employee who called to discuss my request for getting a quote was polite, knowledgeable, honest, and up front about the type and quality of work that they perform. If you are looking to try and get something done as cheapy as possible and don't care how long it will last, you should look elsewhere. O'Sullivan Installs has a focus on quality and durability. I was given a very thorough explanation of why the company would not replace a storm door without also replacing the exterior door. This was not due to wanting to push more work on customers but because replacing a storm door without redoing the doorway would result in a storm door that would become misaligned within 6 to 12 months of being installed (my current storm doors issue). While I did not move forward with having work performed with O'Sullivan Installs due to plans on moving in the near future, I will be reaching out to first if I ever need to have any work done as the up front honestly about their company and work was extremely refreshing.

Great responsiveness, service and product. Other reviews were right, these guys deserve their rating. Have already recommended them to others.
