We recently had our windows upgraded through Brennan and are very pleased. The entire process was smooth. Jeff and Pat, installers, were fantastic making what could have been a nerve-racking experience positive. I highly recommend this company.

Concerns with prior door and jamb replacement that were addressed by Brennan Enterprises to complete satisfaction. Brennan dealt with the manufacturers for warranty, supplied free labor for replacement. The whole process took a while, but was completed with total satisfaction. Thank you

Carolyn did a wonderful job helping me select the perfect window and gave me a quote right on the spot. So many other places take days to get you a quote. The installers were efficient and professional and made sure it was done perfectly. My new windows were for the master bedroom and it changed the entire look of the room and now the view is so clear and the room seems so much more insulated. There was no pressure to do my whole house at once and she reassured me that many people redo their house in stages. It is perfect for us. Great company and we will be continuing on until our house is done!

6 years after our original level 4 roof install we started to upgrade the paint scheme of the house. We started to remove the gutters so the fascia could be painted and behold we discovered that Brennan installed the drip edge on top of the felt instead of directly on the roofing plywood! Now we have to get a contractor out here to repair over 200 linear feet of drip edge and roofing before we can paint and rehang the gutters!!

My windows were installed and although the installation team had to come back 3 times on two different to complete everything I am very happy with the windows, they look fantastic. The only reason I am not giving a 5-star rating is because the installation team broke the bed in my master bedroom when they moved it away from the window. Other than having to repair the bed, the overall experience with Brennan was great and I would recommend them to friends and family.

Took quite awhile after the measuring to get the parts ordered and in hand, then another few weeks to get the installation done, but I chalk that up to them being busy and working through their work load. Initial appointment 4/22/2019, signed contract 5/6/2019, 5/13/2019 measurements taken, 5/16/2019 materials ordered, 6/14/2019 I inquired about how much longer for the installation, 7/6/2019 the installation was performed. Once the installers arrived, they tore out the old door, installed the new door, cleaned and picked up everything and the job was complete in one day. After about a year, the door was sticking and operation was getting harder as time went on, I wasn't worried at all since the door has a lifetime warranty I called and a technician was dispatched checked out the problem, ordered parts came and installed the new parts and the door is back to working as it should. I am a little concerned as some of the cladding had to be reordered and redone, which now has seams in it rather than one solid piece, but again with a lifetime warranty I trust if there's ever an issue Brennan with uphold my warranty.

We had all our windows replaced by Brennan’s in 2016. They are beautiful, easy to clean, and we’ve definitely saved money on our utilities. In addition, the new windows cut the outside noise from the nearest freeway way down. Five years later, they still look brand new. They did the job in a timely manner and cleaned up after themselves. I would use them again and definitely recommend them.

Excellent overall experience. Installation was handled very well despite some challenges. One of the installers even came back on a weekend to finish details and touchups. Pricing and product were generally a good value. Products have held up very well since installation. Would recommend. (Been meaning to post this review for a while now)

Over the last 10 years Brennan has done several jobs for us. Some were very large and some were very small. Recently we needed a gable vent replaced. Certainly not a large project, but Brennan executed it as if were a 30K job. They are responsive, courteous, and on time for appointments. Most importantly, they executed the project flawlessly and at a fair price. If you are looking for a contractor that does what they say they will do look no further than Brennan.

After researching several doors and companies, I selected Brennan Enterprises to provide the patio door and installation. The Anderson door installed is top quality, very durable, and I am extremely happy with it. It should last a lifetime. The installation was outstanding and performed relatively fast by two professionals. They knew exactly what to do, took care to protect my house, and cleaned up thoroughly when complete. I highly recommend Brennan Enterprises and Anderson doors. I will definitely use Brennan again in the future.

The time frame was great , they came out and went over with us on what type of doors were available and the prices, we then picked out the ones we wanted and they then had the installer come out and measure the places that the new ones were to go. When the new ones came in they called and set a time and day to do the installation. When the job was finished all was top notch.

I would highly recommend this company. They were very professional, returned calls promptly, arrived in time, and did a great job putting a beautiful new front door with sidelights and a back door on our house. They did the work quickly with very good attention to detail so that both doors are beautiful and well insulated.

Brennan Enterprises did a great job installing our new windows and patio doors! Garrett and Brody were very nice to work with, worked efficiently, and cleaned up very well every day. They worked around our unpredictable spring weather to get all windows and doors installed in a timely manner. The new windows and doors look great, and we're looking forward to improved utility bills! Excellent job!

Brennan Enterprises did an excellent turn-key job from old door removal to replacement to painting. The replacement door does not look like a replacement.
