We were referred by our neighbors and were really nervous about such an important purchase of new windows. We are so glad we went with Brennan. From start to finish everything was easy, fast, and delivered as promised. The people who came and installed the windows were very clean (especially during these CoVid times) and you couldn't even tell they were at our house and installed windows. They covered our furniture and really did a great job. Love our windows and final product! read more

Ordered a patio door to replace a door and window. It took almost 4 months to come in and then I found out that it was damaged. The sad part is that Brennan enterprise didn't tell me but I found out. I asked if they would offer discount since it was damaged then repaired and they said NO because it comes with a warranty. Also what was surprising is that I was told that if they wouldn't have told me I wouldn't have known so I replied and told them they didn't tell me but I found out and that's when integrity comes in to play. Also they want to explain that they order door from another company but I told them that I ordered from them not their supplier. I needed a front door too but I will do business elsewhere. read more

We had 19 windows replaced and had another structural issue that we needed addressed. From the time Carolyn came to give us a quote and show us the windows, to Will, who came out and installed a small window in our bathroom and constructed a wall in which brick will be laid, to Pete and his crew came out to install the 19 windows, it's been smooth as can be. The installers were careful, considerate of our property and quick. The took down our wood blinds and replaced them after the window was installed. So they left and my house it totally back together and I have absolutely beautiful windows! They deserve more than 5 stars! I was kept in the loop from start to finish, so no surprises! And the best part is the entire project cost about 1/2 of what we had originally anticipated. read more

I was SO hoping I would have a 5 star review, but honestly I just don't. I would give it 3.5 but I can only choose between 3 or 4 so I have to rate a 3. This is based on the initial stress of 5 days of work, and it not being done right the first time. Also, having to contact the company numerous times to even get someone out to look at the issues. I will say the owner is very nice, and obviously expects his workers to do a great job.. the problem was I don't think anyone in the company was willing to notify him of issues until I posted a review. I was concerned they were sending the initial installer to do corrections, even though they sent a supervisor out to work with him. In my heart, I knew the windows weren't sealed properly the first time, but I also knew maybe this was a teaching experience for him and that's why they were sending him out. They agreed to remove all exterior trim and fill in the gaps... when that was done it was obvious it wasn't done right the first time. The supervisor told me this was a bigger job than the installer could handle the first time and should have asked for help. So they removed all trim and sprayed the foam filler to seal the windows... the foam filler came in through the trim on the inside of my windows, so obviously there were huge gaps before trim was placed the first time. I pointed this out , and that it was concerning . The supervisor told me well at least now you know it's really sealed now and there shouldn't be a problem. I'm glad, and positivity is great, but this shouldn't have happened in the first place. After they were finished there were 2 window ledges on the outside that had damage.. you could see where something was used to pry the trim off.. there were dents in the siding. These were windows where the first installer was removing the trim in the back. When I pointed it out to the supervisor he told me they didn't use any tools that would have caused that, insinuating that the damage was already there. It wasn't. I could see where the paint had been scuffed and dents. To his credit , he did come out to replace the siding on that window the next day, but I felt he was irritated they were having to do this. So job was complete, and I couldn't be there the next day as I had to work.. I had already taken a day off again to be present for the work. When I got home i noticed there was a long strip of white caulk on on of the front windows , down the brown trim. I'm thinking why would anyone think this is okay? It looked like they ran out of the brown so just thought they could seal it with the white. So frustrating. I messaged the supervisor and he did come the next day and fixed it. This whole job on my 1000 sq ft house took 7 days to complete. I am not bashing the company, I think they probably do great work for the most part, just not sure why I had this experience and had to fight so hard to get them back out. Windows seem good now... not noticing drafts like I was before. This just took way too long, and should have been done correctly the first time. I had to take vacation time at work to be here on the extra days. Just thankful they finally agreed to fix the issues. read more

Great work, wonderful windows!!! I couldn't believe that new windows would make difference in appearance of the insider and outside of my house. Great company and great work. I would recommend them to any one. My sales lady Carolyn was very professional and I would use her again. read more

I had 16 windows replace by Brennan Enterprises. I was really pleased with the experience. Cindy came out to my home several times with window to show color, durably and grades. I was on a budget so she really worked hard to get me a great window to fit my budget. Priced out several manufactures and held the quote for several months. When I made my decision sh came back out with the window I chose. Work was set up and the crew did a fantastic job. Took a day plus 1/2. They cleaned up was done so well I had NO dust or debris to clean myself. fantastic job and the windows are not only wonderful but have saved $$, as well. I highly recommend this company that has been in business for 30 plus years. No worries about the disappearance of the fly by night companies that offer a great deal today and gone in a few years or even months. read more

Don't request a quote from here unless you like to be woken up at 6a. Katherina was our wake up call this morning. Not a good way to get business. read more

Our sales rep Devon was great, our installer Willy was excellent, and the products are good as well. Brennan is our favorite contractor. We recommend them to everyone. read more

When a double pane insulated window (1 of 4 custom 8'x4' windows) lost its seal, Brennan offered me a great deal on replacing all 4 since they were past their expected end-of-life. They promptly sent a senior level expert to measure all four window openings. They had several quality/price levels to choose from and gave me a firm delivery date, which they met. The installation was expertly done in a timely fashion and the improvement in the view and how the room looked was amazing! The caulking and finish work was as good as I have ever seen, and the clean-up was nearly flawless. I have no reservations about recommending Brennan for glass work. read more

I have spoken to several window companies in Dallas. Although Brennan doesn't offer the particular windows that I want, the salesman stood out because he is the only person out of the many who left me with a quote and followed up. That says he is more legitimate than the many who tried to lock me into a price on the spot, which is very shady when you are making a huge investment. One needs time to compare and research when making such a decision. The Brennan pricing was a little above some but not near the pricing of Andersen Renewal. I will consider them as an alternative if I am not able to find the exact windows I want for my home. read more

Good service and good installation. If you are looking at doors or windows, I would recommend them. They carry several lines of products. I tried the Lowe's / Home Depot route, but that was a mistake b/c they sub everything out. With Brennan you are dealing with them the entire process. They are also cheaper than Pella. read more

A great company! We just had them replace all our house windows and were so impressed with the professionalism of all the people we interacted with from the person who did the quote to the office staff to the installers. They gave us multiple choices of windows to choose from and listened carefully to our issues/concerns/wishes. We are thrilled with the windows...we only wish we had called Brennan sooner than we did! read more

I was very impressed with Brennan. We had an old carport torn down and a new one put in it's place. They were here on time and finished in one day. They were very professional and even cleaned up everything. They actually went above and beyond by hauling off some extra scrap metal that I had and when they dug the holes for the posts, they placed the extra dirt in a low spot that I had in my back yard. We will absolutely use them again when needed for any outside remodeling. Great company, Great customer service! read more

My wife and I had a patio cover installed a couple of months ago. The process was so smooth from the quote process to the crew installing the patio. It was done on time and no trash was left behind. I would use them again in a heartbeat for another home project. read more

They deliver what they promise! great windows, great install, great follow up - all from a local business. I couldn't be happier. And oh, by the way, how many contractors have you heard of that say "wait, don't pay me anything until the job is complete." That's how they roll! read more

Our window replacement experience was perfect from the initial consultation to the final installation and billing. Everyone we worked with was polite and professional. There were two manufacturers defects on two of the windows, but Brennan made sure they were fixed promptly, and our bill for the project was not presented to us until all of our new windows were perfect. I would gladly recommend Brennan Enterprises to anyone, based on my experiences with them. read more

Five stars aren't sufficient. Brennan is our favorite contractor. They respond well and do excellent work. Their prices might be higher than some, but their work product is worth it. Devon has been our sales manager for our doors and our windows, and Willy has been the installer. They are both excellent. Thanks, Brennan! read more

Brennan is probably the best services company I've ever worked with. I say this simply because of my personal experience with this company over the past ten years. Almost 10 years ago I paid Brennan to strip the rotted "wood" off my 2-story chimney and rebuild it using vinyl siding. So late in 2018 I found that the chimney was starting to shift and called Brennan out to take a look. Keep in mind I never expected anything more than an estimate to fix something, and at least I expected an argument over responsibility for fixing the new issues. But Brennan sent a team that started at the top of the chimney and stripped it back to reveal that somehow a slow leak caused some harsh wood rot over these years and the current condition was bad. At that point Brennan told me that THEY WARRANT THEIR WORK TO THE ORIGINAL BUYER FOR LIFE. They then got to work and stripped the chimney from the top to the ground and rebuilt it, frame and all. This job took nearly 3 days plus the use of an elevator. When they completed this, they shook my hand and thanked me for being a customer. Who else does this these days?? I worked with Emelda & Frank for the most part - a super nice team and extremely happy with every aspect of my dealings with this company. read more

Used Brennan Enterprises before for window replacement. Loved their work, courteous employees, efficient. When it was time for siding replacement, we called them for a quote and hired them for the job. I had changed my days in the office to be present during installation - I was working from home. Day one of installation was fine. Day two was where the disaster started. At 9:30 AM, while I was on a conference call, my phone, tv and internet go out. I walk out to find one of the contractors holding the FIOS box by the wires, after having removed it from the outside wall. Each of the 3 panels of the box were open (assuming they couldn't determine what screws mounted the box to the wall). That started a 100 hour nightmare in getting our services back up. I did have a Verizon/Frontier technician come out within 2 hours of the incident and advise Brennan Enterprises, over the phone, that the outage was directly related to how the box was handled and that a port within the box was broken. Thus, I was unable to continue working - 6 hours gone. The siding installation was finished that same day, but Brennan had to schedule a walk through for a future day (after I complained that a few items were not done correctly). The siding installations problems were resolved, but I had sent an email to the company requesting a credit on the cost due to the problems THEY CREATED when removing my FIOS box. That email went unanswered. 4 days later, I received an email from the company with a Completion Certificate to sign as well as payment due. I emailed the signed Completion Certificate with payment instructions, once again attaching the email I sent 4 days earlier asking for a response. Here I sit, one week later and have received NO RESPONSE to my email. I cannot believe that a company would not want to attempt to compensate their customer for a loss in services that they created. Not only just a loss in use of my phone, tv and internet for a total of 100 hours, but the loss in work productivity. However, no written response to my emails is completely unacceptable. read more

I unfortunately had a terrible experience with Brennan Enterprises. I used them based on a referral from someone and was disappointed with both the number of service issues as well as the response to my attempts to receive remediation for the issues. To install replacement four windows in my house, it took 9 visits by the installers. I wish I had a better experience to share. Glad to hear that others have fared better. read more

These guys installed two new windows on my den upstairs and replaced rotted wood and painted them to match colors. I couldn't be happier with the quality of the windows and the work these guys did. Will definitely use them again to replace rest of windows and doors. read more

We had 17 windows replaced and will have another 23 done next year. Brennan will also be replacing courtyard doors and one other exterior door. One comment - We'd like to suggest that the time is taken to explain to customers that there is going to be a considerable amount of "dust and debris" generated from the removal and installation of windows and it takes a few days for all the dust to settle and not be floating in the air. Rooms that were a distance from where the installation occurred had a great deal of dust in them and it took a few weeks before all the clean up from the install was done. We'd like to suggest that perhaps a check list be handed out prior to an install would be beneficial to customers so Brennan can remind them to be sure to close all doors to rooms throughout the house to help eliminate the spreading of dust. We'd also suggest that where there are open areas (with no doors) leading from one room to the other, a plastic cloth should be hung. In addition, drop clothes should be put down in rooms where work is being done. Having hand scraped wood floors with all the dust was not pretty. Nothing was protected in our home except a cloth was put over our television in our family room which only came down part way. The crew was very professional and I think quite good. The windows are lovely and add so much to the appearance of our home. Much less noise is being transmitted into our home. One final comment. It would be beneficial if a demonstration on how the windows work was done before the crew departed. It would have helped us to see the window mechanics after install. read more

Having Brennan Enterprises put siding on my house was the worst idea I ever had!!!!!!!! I am now going to have to pay for someone else to take it all off and put new siding on right. Even after multiple attempts to fix their mess, my siding still runs down hill, but not as bad as it did before. It is also starting to fall off. If you want to get RIPPED OFF BAD, call Brennan Enterprises. I wish that I had just flushed the money down the drain, I would not have to go back and fix the mess they made before having someone competent install my siding read more
