I have been very pleased with Brennan. We have a large number of windows in our house and were able to get one price that was guaranteed, while having our windows installed a few at a time. They have always been very pleasant to work with and timely. The windows are of good quality. When looking at other companies, it was an 'all at once' installation, which made the cost daunting for us. Over time, we have almost completed all of our windows and I'm extremely pleased with everything overall. I highly recommend their services

I had a great experience from beginning to the end. The installers left the area cleaner than they found it! ;) The sales lady was extremely knowledgeable and super friendly! I never felt pressure to purchase anything, but I ended up buying several picture windows that overlooks my pool area. I absolutely love my new windows, and they've proven to be energy efficient! I would really love to replace all of the rest of the windows, in fact, I hope they reach out to me and make me a deal that I can't refuse! I highly recommend Brennan Enterprises!

5 Stars for all areas: sales, installation, clean-up, customer service

I highly recommend Brennan Enterprises based on the experience I had with them in the matter of Window replacement and patio enclosure

I love my new windows! I'm amazed at how much sound & heat they keep out. The installers were quick & professional. Brennan gave me options other vendors didn't take the time to consider. The quote was exactly what I paid - no price changes! I absolutely recommend Brennan Enterprises for new windows & doors. :)

Over the course of 3 years we replaced all the windows in our home and could not be happier with the results!! Energy Efficiency, Easy installation and they look GREAT!! Brennan is the real deal and highly recommend their sales, service and install teams!!

This Company will back their product and make sure the job is done right.

This company is the real deal. From sales to completion, the process was professional and every detail was 100% accurate. There's no hard sales pitch. The communication is excellent. The product is great and the installation team is stellar! We had several projects done over a 6 month time frame and I only wish they all went as smoothly as this one.

Brennan Enterprises replaced all of our windows and replaced all of our eaves and overhangs. Anytime we had a problem they were there to take care of us. I highly recommend them.

Brennan did an excellent job on my new windows. When I had an issue with a couple of the windows a few months later, they were prompt in getting it fixed.
