A selection of 700+ homeowner reviews:
“Brennan did the install of 16 windows. I'm still amazed at how professional and knowledgeable they were. I had no mess to clean up at any window. They even covered the shrubs outside the windows and worked around things that couldn't be moved. I can give them the best referral ever—an A+++. I would use them again without hesitation.”
“Brennan Enterprises did a great job replacing our windows. Everyone was very professional and knowledgeable. Follow-up was immediate. We'd absolutely recommend Brennan.”
“The install experience was wonderful. They handled taking down any window treatments and moving furniture. They cleaned up after, and they replaced the window treatments. Overall, I would give them a A+++ rating.”
“They did an excellent job. It was a quick and easy process.”
“We have used Brennan to replace 20 windows The Andersen windows meet and beat the reputation. The experience with Brennan is first class from the estimate to the install.”
“Very professional company from start to finish. Our salesman, Tom, was experienced, professional and low pressure. He listened to our concerns and addressed them. The installer, Howard and his assistant provided a clean and professional install. The windows look great.”
“We recently used Brennan for window replacement for our entire house and had a very positive experience with Brennan. Everything was managed in such a professional manner from the initial meeting for a quote, to the scheduling, to the installation and all communications throughout. The installers worked quickly and cleanly. We continue to be very satisfied with the windows we purchased, they are really great quality.”
“Brennan Enterprises did a great job, from selecting the windows through final installation and clean up.”
“My new windows are even better than I expected, and the installers were amazing.”
“Brennan installed my patio doors and a few windows. I have 10 more windows to go. It was really nice to have the same installer Frank perform the installation. I cannot give him enough accolades for his professionalism and skill. You wouldn't have known he installed windows because he cleaned up the space very well.”
