HOMEOWNER REVIEWS SELECTED FROM SURVEYS COLLECTED:

“They did a great job. They did new windows and they did new siding. They were just quick, thorough, and kept everything clean. I'd give them the highest grade—A+.”

“The entire work was exceptional. They did a window, siding, and roof on my house in Dickinson, and then they did a roof and siding here in Tech City. They did A+ work.”

“It was an excellent experience. They came, they did the job fast and clean—well-done, and I was very satisfied. They replaced all the windows. They're A+.”

“They were just great all around, from sales all the way to installation and clean-up. I haven't had any issues with them. They installed ten windows in my house. I'd give them an A+.”

“I liked the salesperson—his presentation and ability to detail the product, and what the difference is. The installers pretty much cleaned up after themselves. They knew what they were doing, and I haven't had any issues—no worries. They did window replacement. I'd grade them A+.”

“They were very quick and thorough. They were doing window replacements. I'd give them an A+.”

“I had no problems whatsoever. They've done siding in the past, and then they've done my windows. They've also done my front door. I'd grade them A+.”

“They came out, did all the installation as expected, and left everything as it was before. It was what we'd hoped for. They did both siding and window replacement. I'd give them an A.”

“They put in 27 double-pane windows for me. They were straight to the point. When the subcontractor/installer came by, he had up-to-date, new equipment, showed up when he said he was going to show up, and had good workmanship. I'd give them an A.”

“It was a good experience. I'd done business with them before. This wasn't the first time, so it was a repeat. They did siding, windows, and also a roof. I'd give them an A.”

“The crew was friendly. They provided siding and windows for me. I would give them an A-. I'm still cleaning up some of their stuff. The weather's been bad, but they used my hoses to wash off their paint and cleaning apparatuses, and now I have to clean the hoses.”

“They did window replacement for me. They're dependable. The customer service was fine. They get an A.”

“They did some work for us. They put in windows for me—whole house—and they did some Hardie plank. I thought they were very professional. They got the job done quickly and cleaned up well.

“We had a great experience. A lot of those big window companies will come in and give you a sales pitch, and your husband has to be home. They want two hours of your time. We went to use one and—first of all, I'm not spending $30,000 on a window, but also—we just needed 8 windows. We weren't super worried about the argon caught between the windowpanes. It was more, 'Is this going to hold up?'; 'Is this the right window for us?', in terms of wear-ability and price. Greg Fisher got it. He was like, 'I can give you the speech, or I can just tell you that these are the options', and that's what we did. I'd give them an A.”

They were very thorough, worked really hard, and cleaned up after themselves. They did replacement windows for all the windows in my house, and they did HardiePlank siding. I'd give these guys an A—they did a really good job. It all depends on the crew you get, but these guys were pretty good. They did a good job.”

“They took the other windows I had in, and they're supposed to be double-paned windows right now. They were real good. Plus, they cleaned up the back after they finished.”

“They did a good job. I had new windows put in. I'd give them an A rating.”

“They did the windows for the whole house. Their customer service was pretty good. We had to call back because some of it was not fitting well, and they had to come back. I would recommend them, and I would say they're an A.”

“I liked their thoroughness and their customer service, and they had a kind work crew that was always nice to my kids and accommodating. They got the job done as scheduled.

“Everything they said they were going to do, they did, and they did everything in a timely manner. They worked very professionally. They installed some new windows in the whole house. I would suggest them. They deserve an A.”

“My experience with Allied Siding & Windows was excellent. The product is excellent, and their crews were really good, informed, and very helpful. I have absolutely nothing bad to say about them at all. They installed panel windows upstairs and downstairs, and they installed double French doors in the back. The product is guaranteed for life. I'd rate them as an A.”

“Allied Siding & Windows did a good job. They changed all the windows, and their customer service was wonderful and professional. They deserve an A grade for their excellent work.”

“It was done quickly and professionally, and it was very good quality. They put wall windows in, and their customer service was very good. I'd recommend them highly—they're an A.”

“They did an excellent job, and they were honest. They replaced all the windows in our home, and I would give them an A.”

“Allied Siding & Windows replaced the windows for my whole house, and it was good. They had a good product to begin with, and the people who replaced the windows were very good. They could answer all my questions, and they knew exactly what they were doing. It was 13 or 14 windows, and they did it all in one day. They got it all done to my satisfaction. It was an A+, and I am very picky, so it says a lot that I would rate them highly.”

“They're excellent. I would use them again. They took care of windows and doors for me. I did get some estimates from other companies, but I decided to go with Allied based on some of the things they told me. I think they brought pictures in a catalog, too. My expectations matched the final product, so they get an A.”

“I love my windows. Allied was quick and efficient. They did the windows in the whole house, and they knew what they were talking about—they were knowledgeable. I chose them because my husband's coworker was using them, too, and he had a positive experience. I was referred to them by a trusted friend. I would give them an A rating.”

“Allied Siding & Windows did all the windows in my house—about 15 of them. They broke everything down about the stuff I was buying, and that made it a positive experience. It was cold when they installed, and they helped us keep our house warm. They offered advice on what to do when getting the windows installed. I heard what type of work they do, and I just went with them. I would give them an A+ grade because they did a great job.”

“They did some windows for me. The crew showed up on time, and they finished ahead of time. They charged what they quoted me; there were no additional charges. The windows look like they came with the house. I chose Allied for two reasons. Number one, they have been in business for so long. The other reason I chose them was their product—they had a better window than anybody else. They deserve an A+.”

“Allied Siding & Windows replaced some windows in my home. This was my first time using Allied. I would give them an A+.”

“I thought they were wonderful—they were fabulous. They replaced all the windows in my house. That was my first time using the company. A friend of my husband's had them do windows in their house, so that's how I heard about them. I'd give them an A+; I really would.”

“The work Allied Siding & Windows did was fantastic. They replaced windows for me. The quality of the windows was excellent. The cleanup was great, too. I would put them at an A+, and I would use them again.”

“I thought they were great—they did a great job on the windows. I hadn't used them before. I would give them an A+ grade.”

“They were great. Allied Siding & Windows replaced all of our windows. It makes a mess, but they cleaned it all up, inside and out. They even had a lady that dusted and swept inside, and they were very nice people. I had no problems with them. We had a few little issues after they left; not anything bad—it was just they forgot caulking a couple places and little things like that, but they came back and fixed it all, and they were great. Everything's held up fine. The windows are great, and they shut out a lot of the noise—we noticed that right away. And I don't notice my air conditioning going on as much as it did, which means they are being energy efficient, I think—because I can walk up to the windows now and not feel the heat or the cold. Before, we had single-pane windows that the builder put in, and you could go up to the window in the summer feel the heat and in the winter feel the cold, and I even had somebody power wash my sidewalk, and the overspray came through around the windows. But I don't expect these windows to do that at all. They're easy to clean, easy to pull out—I've already tried them, and they're very nice. And the neighbors all have commented how nice they look. I had three companies come out, and we had three estimates, and we picked Allied because of the quality of the window itself. We plan to use them again to build on a back porch; we have one, but it needs some work. I would give them an A+.”

“They replaced all of the windows in our home. The quality of the work was very good. I would definitely use the company again. I'd have to give them an A+—they were very professional, very quick to call me back when I emailed them about possibly doing a bid. The called me back within probably 15 minutes, put up the estimate, and it was very well in order. As far as the windows, they came on time to install them, had them all done in one day, and did a great job, so I would definitely tell a friend or someone to call them.”

“I liked Allied's customer service, the quality of the product, and the quality of their work. They replaced windows in my home. They did an outstanding job. I loved it. They did it all in one day. We called them in the spring of this year, and three weeks later they had our windows in, and the work was done. I would give them an A+ grade. I was very pleased with the service and the work that they did.”

“Allied Siding is a great company. They did all my windows. I heard about the company from a friend that I work with. I would use them again. I would give them an A+ because everything was great.”

“The two installers from Allied were extremely professional. They took a lot of care with all our belongings. We have antique furniture, and so they were very, very careful with moving anything that needed to be moved, which tickled me. They installed new windows on the entire house. I would give them an A+.”

“They came in and replaced all of my windows. There was a team of guys that came in, and they were very professional, cleaned up after themselves. They did a really good job. They finished job quickly. In fact, they got it all in on a Thursday. All of the windows were in on Thursday. Friday, all they did was came and caulked, cleaned the windows, cleaned up things, and they were out of there. It was a really, really good amount of time, very much so. A friend of mine had told me about them; she used them, so I just went off of her lead, and then I was really pleased with it. So far, everything's held up wonderful. They should be in there for a lifetime, but so far it's really good. They're an A+.”

“Allied Siding & Windows replaced windows for us. They came out when they said they would and did the job when they said they would, and the guys that did the work did a real good job. It was a good experience. I actually called them just a couple days ago to come out and give me another estimate on some more windows, so it was great—it was no problem. I would grade them an A+.”

“Allied installed windows for me. Everything was good. I purchased single-hung windows. The cleanup was good. I'd give them an A.”

“I think they came in here and every day they cleaned up. Whenever they messed up something, they cleaned up, and they are kind of on schedule. It's kind of a new company to us—we got to try it out, and it's pretty good. I would rate them an A.”

“Allied Siding & Windows did windows for me. They did really good. I'd grade them an A. The workers were great.”
