“Brennan Enterprises did storm doors—I thought it was great. They did a great job. I think the sales person was extremely good, very informative—took time to answer all my questions—and the installer was exceptional. The installer was amazing, and really did a great job. I did two custom, sliding-glass doors, so they were a little bit more complicated than the average order—so they did a great job. I'd give them an A; I have nothing but good things to say. They did a great job.”

“Great. They repaired the siding that was ruined from the storm. They did my house about 15 years ago—the siding, new windows, and all. They've always been real good. They're just good people. They do good work, they clean up after it—everything. They're just real easy to deal with, so it was an A. They even went out of their way—Mr. Brennan did—to take care of problems we were having with my insurance company. He did some excellent work for me as far as providing them with everything they needed to make sure I got the best deal possible.”

“It was excellent. They do everything great. This is the second time we bought their windows. We love their quality and services. I'd rate them an A.”

“They're fantastic—I mean, just their customer service was good. They were timely. The product looks fantastic up on the windows, so it's just all-around great. They just replaced solar screens; they replaced those for us. I'd give them an A+ for sure.”

“They're fantastic. The quality of their products is excellent. Their communication is good. They're timely, their quality of work is good. I don't really have any complaints at all. They installed about 15 windows, and they also installed a front and back door for us. Two separate installations, about a year apart. I would give them an A+. We would call them again.”

“The workers that they had doing the work were very excellent. They went beyond the call of duty in what they did. They were willing to help and do side jobs. I volunteered to pay them if they would do it, and they did; the windows went in beautifully and we've been totally pleased. I just had windows. I would give them an A.”

“They were fabulous. I liked the quality of the product. I've worked with them for many years. I had a small issue with the window. They came back, replaced the whole thing—no charge or anything. For the second round of windows at the front of the house, they came and had an excellent service provider and excellent quality work so I'm very, very pleased. I couldn't be happier. I had no complaints—A's across the board.”

“They did our windows. They were excellent. We've used them a couple of times now, and their work is very good—they're timely, and they're clean. They have excellent products. They've done windows in two different houses. It's an A+.”

“They just came out, and he was very interested in making sure what we wanted to happen, happened. He explained all the different kinds of windows they had, and then showed us what we needed to make it all work. They were fast, cleaned up after themselves, and they were very polite. I just couldn't have asked for anything better. It's definitely an A+, and I would recommend them to anybody. They were awesome.”

“They replaced a patio door. One: they were just very friendly. Two: they were very knowledgeable about the various products that I could swap out, and during installation they were very professional, cleaned up, and didn't leave a mess. It was awesome; I'd rate it an A+.”

“We did the windows. They were fantastic, so I'll give them an A.”

“I had a good experience with them. I was satisfied. They just did a pretty good job as far as I was concerned. It was just some doors. As far as I was concerned, they did a good job. They just installed a couple doors. I'd give them an A, because they were real friendly people, and they did a good job, as far as I was concerned. Overall I thought they did a pretty good job on customer service. The windows have been in for about six, seven months now. The door's been in for about seven months, and I haven't had any problem with them. They did a great job.”

“It was awesome. They replaced several windows; I don't recall exactly the extent, but large, plate glass windows. It was all A work.”

“The customer service, the salesman, and the window installers did a fantastic job. They went out of their way to make sure we were happy, and I really thought they went above and beyond everything that they needed to do. They replaced the windows at home. They were an A.”

“They're fantastic. Very, very good work. They put in seven-foot windows in the front of the house. It'd be an A. They're very good.”

“They've just always have been reliable, on time, great work, great cleanup—and just very personable. They've done windows for us. They are an A.”

“Brennan Enterprises replaced a set of door and window sets. They did their stuff on time. They were very professional about it; everything fit, and then they came back and painted it like they were supposed to do, and everything was clean and tidy at the end—no issues. I'd give them an A+. The deal was that, I had an area that was sort of rotten, and my windows were leaking. So, it's been over a week, and my doors and windows don't leak and they still look good. When they finally finished cleaning up and doing stuff, after the painting, everything was nice, neat, and no problem. They seemed to be knowledgeable. I wouldn't have had them if I thought otherwise.”

“Brennan Enterprises did what they said they were going to do and did it in a timely manner. They did windows, siding, and a patio cover. It was very good.”

“I dealt with Brennan before. They're the one that I purchased my windows and screens from, and they did all my siding. They did my soffit when I was building my house, and Brennan Enterprises has been really good. They replaced my French doors recently, so my experience has been positive. I'd grade them an A.”

“Brennan Enterprises just worked with me as far as, what I needed, they arranged it—because I just needed a replacement window, and they got it; they picked it up, and there weren't any problems. I'd rate them an A.”

“Brennan Enterprises replaced the windows in our house. I thought it was good, and I had no complaints. I'd rate them an A.”

“I'm doing gutters for them, and windows. It's been good. I've got no complaints.”

“It was good.”

“The salesman made it positive. Everything is an A.”

“Their schedules were on time. They said what they were going to do, and they did a good job—cleaned up everything after they were done. They did windows—replaced the front door, and all the windows. I'd say it's an A. They knew what they were doing.”

“They completed the work, and they did what they said. They changed the windows, out. Things like that. I'd rate them an A. Quality of work was very good.”

“They installed my windows. They did well. They did a good job on the windows. It's an A.”

“They were easy to work with, they kept me informed about everything, and handled the insurance with ease. It was a window replacement. It was an A.”

“They were on time, and they did quality work. They did windows for me, and I would rate them an A.”

“We had some windows replaced, and a door replaced in the back and we moved before that work was completed. We had them do work for us many times. They were very good. The quality of work was good as well.”

“We just liked the installer and the sales person—they weren't pushy, they were professional, and they did a good job. They cleaned up when they were finished, didn't break anything. They replaced windows. I would give it an A.”

“They installed windows for us. The windows are great. I think they did a nice job, like, they cleaned up after themselves, because they had to take out windows and put new ones in. They cleaned up after themselves, and they were very friendly—the installers. The salesman was very responsive, even, through text messages and emails about different pricing—and things like that. I'd say it's an A+. I have no complaints.”

“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.”

“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.”

“They did a very good job with the window installation. They were on time and finished when they said they would. We had a problem with the replacement French door which took three reworks of the door to get it to the proper size and door opening configuration. This wasn't a problem with the installer but from their door vendor. It was resolved and looks great.”

“Brennan was recommended by a friend who was very satisfied with the work they performed during their renovation. I too am very satisfied with the windows they installed for me. The quality of the windows is excellent and the workmanship is top-notch.”

“I am extremely satisfied with my new windows.”

“I needed windows for my new home and Kerry and the staff at Brennan were fantastic to work with. Great customer service, and they gave great advice on my purchase.”

“Brennan replaced a window for us, and we are very pleased with the results. The people were very friendly, and easy to work with.”

“We liked that they helped us understand the different types and features of various windows and then helped us identify the brand that met our preferences. They were very neat and dependable during the installation. They caught any flaws in the windows or caulking and repaired without prompting. Great communication.”

“I love my new windows, and Brennan Enterprises did an excellent job. I would use them again.”

“We are very happy we chose Brennan for new windows. Quality product and excellent customer service. The installers are truly craftsmen. Very skilled and knowledgeable regarding home construction.”

“As a homeowner for 40 years, this was the best experience with major repair I've ever had. Service was superb. I will never use another company for widow/door, etc. they are the best.”

“Each step of the window replacement process was great. Each employee we dealt with was fabulous. The windows look so good we haven't even put up window treatments on some of them.”

“We were very pleased with the job that Brennan did in replacing the windows in our home. Cindi Brennan was very knowledgeable and went out of her way to get us the windows that met our needs and she followed up to make sure that we were satisfied with the results.”

“My windows were done professionally. The service guy was timely and was efficient.”

“Was recommended to Brennan to replace windows. They did a fantastic job, and I'm very pleased with the work. I will definitely use them to replace other windows in house and recommend them to others.”

“Very nice job for replacement windows.”

“I had a custom window made and they were very helpful in getting it made correctly.”

“The installers were very knowledgeable and skilled. They had to remove my shutters, and I was terrified they would ruin my painted paneling not to mention the shutters. I was shocked at how perfectly they removed and replaced the shutters and the casing. There was no damage and I was thrilled. They caulked and filled holes, looks just like it did originally. The windows are perfect too.”

“I liked their customer service and their product. I would say the sales rep was very good and seemed very honest. We also heard something good about it. Also, the installers—Frank, and I think a guy name Willie was with him—were the best we have ever seen, and we are kind of picky. They were so careful with our house, and they walked through the process of what they were doing. They were fast, but their workmanship was beautiful. Their caulk lines were beautiful. They installed windows and doors for the whole house. It took them two days, and they were gone by four on the second day. Frank, the installer, noticed when he unwrapped our sliding glass door that the handle had rubbed against something. He noticed it before I did, and he said, 'We are not going to install that.' He had the warranty people come out and replace it very fast. I only have good stuff to say about Brennan and the installers. If I could have him do all the work at my house, I would—he was awesome. They did a good job. Tom Leopard was our salesman, and he was very good.”

“They had good workmanship and good people that were working there. They did windows for us. We hope for them to come back and finish them up soon; we just keep having things get in the way. We want to get more windows and doors, so there are more to get done by Brennan. We researched a couple of places, and then one day down in our neighborhood, we saw a couple of trucks and saw Brennan on them. The next day, I knocked on the person's door and said, 'Tell me about your windows.' She said, 'Come in; let me show you.' She was real excited about them. She was willing to talk about them and say how wonderful they had been, so I said, 'OK, let's put them on the list.' I think the first day I went, they were still working on them, and they gave me a business card. I was happy with the people that took the measurements and told me about the windows. I think it was wonderful—a great experience.”

“Mostly, I liked their responsiveness, and they were thorough in what they did. We did have one issue after installation that I probably would have never noticed, and they pointed it out and said that they were going to fix it. They were out a few days later and fixed it. They did 13 windows. The quality was great; I was very pleased. I think their responsiveness stood out, but even when I would call early on, they were very easy to work with. I heard from a friend about a specific brand of windows, and Brennan was one of the people that you could go through. When I talked with them, it was a no-brainer to go with them. The windows are holding up beautifully; we're just trying to figure out when to get more done.”

“They created a whole room for me out of glass. They're neat and clean, and they call you if they think they are going to be late, even though they're not. Even if it's ten minutes, they call. I have a deaf dog, and he fell asleep out there, and they didn't know that I was listening—I work at home. They are very quiet, and I heard Pete say, 'Walk around him—he's asleep.' How can anybody be so polite about somebody else's dog? That's wonderful—that's not part of their service. When they leave, the windows are clean, and they try not to step on anything when they replace windows. They put a sliding glass door in the dungeon of my laundry room. Now you can look out at the garden so you don't mind being there. They did several different projects. They are wonderful, and they are always real prompt. The first time, they put up a great, big wall, and it had to get special glass because, instead of having a solid glass wall, people usually have two windows—one above and one below it. I didn't want that, so they made it so that it could go all the way to the ground with two different doors. It goes out to the pool, so they put in a sliding door. If the weather gets too hot like it does in Texas, you can close it, or you can have an outdoor room. They went above and beyond to meet my needs. They would have come out and cleaned it for me, but they told me how to do it, and I did it myself. They fixed the screen because my dog ran through it. It was so clear that he ran into it, and it wasn't their problem, but they fixed it for me. I can think of a million more things for them. They are very polite, and that doesn't happen often; not many people are considerate of your privacy. My electric bill has gone down over 30 percent. I'm really upset that they don't do interior remodeling.”

“The salesman was not telling me a bunch of stuff; he was just a normal-speaking person—down-to-earth. I wanted somebody local who had been in business a long time. They had an accident—they dropped a pane of glass. They replaced two windows, and there were two slabs of glass, maybe four by seven. They took the old one out, and as they got to the front door, they dropped one in the front hall. They weren't frantic or anything like that, but they got after it. They got it cleaned up; of course, they didn't get every last piece of glass, but they worked on it for about 20 to 30 minutes to get it up. They didn't just halfway do it, and I thought that was nice. They were neat and clean. The people that came to do the windows were of course different than the one that came out to talk to us. I think they are OK, and everybody in the neighborhood said they look nice.”

“Brennan Enterprises was very efficient—they were just in and out, and it was just real easy. My neighbor watched when they did the work and said they were really quick. They were very professional, and the guy that came and checked the work also checked my doors. I'm glad I got my windows done with them.”

“We had doors done by Brennan Enterprises, and the installation went very well. We had new exterior doors put on and new storm doors. They totally get an A.”

“They did a good job on the windows they replaced for us, and they were professional. They weren't pushy. I liked the work they did, and I liked their attitudes. They gave a quote, and they stuck to it. They did it within the time frame that they said they would, and I've had no problems with it. At the time that we decided to replace the windows, Andersen was the only brand name that came to my mind. I heard good things about that. I picked the top three people and gave them a call, and they were the only ones who called me back. I liked them because it was family owned and had been owned for a long time. It wasn't a national chain. It was a local, family-operated thing, and that's why I picked them. They just seemed like they knew what they were doing.”

“We had used them before on the front half of our home, and we were remodeling the inside of our home somewhat, so we decided to go ahead and finish off the back side. We decided to go back to Brennan because we had a good experience with them the first time. They were prompt and responsive to our needs, and we didn't have a negative that we could attach to them. It wasn't like we were under any kind of a deadline, but we wanted to try and get the windows done in conjunction with the remodeling, and they were helpful in making that happen. When my wife and I talked about it, they came to mind because they had been easy to work with.”

“We only met one salesman, and he was only here one time to make the deal. Then, one man came out and took all the measurements. They were very efficient.”

“Brennan replaced my windows—excellent quality of work, and excellent customer service and communication.”

“Brennan removed several old external entry doors, and installed new doors. They were on time, did a professional job, cleaned up, and took away any debris or trash.”

“Brennan installed two large sliders and two bathroom windows.”

“Brennan replaced windows and doors throughout the house. Everyone at Brennan was responsive and helpful. The installation crew was hardworking, polite, efficient, and neat.”

“Brennan removed all my existing windows and replaced them with vinyl double-pane windows. Good communication, no haggling, and I got a fair price from the beginning. They honored a six-month-old quote even though pricing had increased on the product. The installers were on time, and completed the work in less time than expected.”

“Brennan replaced my entire house's windows, and added a window where a brick wall was—good customer service, delivered on time, and installed quickly.”
