It was fine, though—they came and did the work, and it was no problem. I'd recommend them, and I would give them an A.”

“I had no negative experience with them at all. They did a wonderful job. The windows were very appreciated in this cold winter. They are very energy efficient and easy to operate. They match very well with the original windows in the house. The quality of the trim work they did outside is very nice. The people cleaned up after themselves very well, and just everything that they did, they seemed to do it very professionally. They were very careful to keep the inside of the house clean while they were working—laid down tarps and cleaned up after themselves. Everything was great. They were one of the window companies that was highly rated in our area, so we picked them, and I'm very glad we did. I would give them an A+. They did everything correctly—period.”

“I've only had two windows done by WindowWorks so far because we're doing it in phases—it's more for efficiency purposes. So far, the technicians have been good, and their cleanup is wonderful. I have no complaints at all. I would give them the A+ grade.”

“A year ago, they installed one set of windows for me, and it was so good that I had them put in new windows two weeks ago. Their salesman was very thorough—he explained everything very well—and I was satisfied with the product. I got the double-hung windows for easy cleaning; those were put in two weeks ago. They showed me how to work them, and the cleanup was excellent. They would be an A+ company.”

“WindowWorks did excellent work. They did good, quality work—quick and quality. They did six windows, I think. They have not had to come back out. I give them a grade of A.”

“It was quick, easy, and simple. My window wasn't opening, so I needed a new window. The cleanup on the job was good. I got the double-hung windows—the ones that tilt in for easy cleaning—and they showed me how to work the mechanism with the windows. I would definitely give them an A+.”

“They were here when they said they were going to be here, and they got the windows done in good time. The workers just worked continuously in the heat; they put in ten double-pane windows, and I was impressed. They took care of everything. I would use WindowWorks again. They provided quality work and quality equipment. I'd give them an A grade.”

“They did some windows for me sometime around the end of last summer. I thought they were all right. That was my first time using them. I think I looked up several people, and as I recall, I think they came back and did an estimate. Everything went smoothly. It was an A+.”

“I was happy with WindowWorks. They installed a door; the quality of the door was exceptional, and the installation was very, very good. This was the first time I have used this company; I found them in the Best Pick Reports. There was a little bit of a sloppy caulking job, and I did get them to come out and take care of that. They took care of it just fine; they came back immediately. I would say they've earned an A.”

“The company's employees were very professional. We had a window on the outer portion of our house, and there were drafts. I could tell a difference with the new windows. I got a new type of window, and they showed me how to work it. I chose WindowWorks over other companies because our neighbors did. I give them an A+.”

“The way that the technicians worked made it positive. They put in some windows. I did not notice a decrease in my utility bill after they were installed, but the quality of the work was very good, as far as I could see. It was my first occasion using the company. If I needed to, I would probably use them again. I selected them because they had done other work in the complex here. It was very good; I have no complaints. I would probably rate it as an A+.”

“Everything was done by when they said, and I liked the way everything looked after it was done. They replaced several windows—so far, so good as to how they are holding up. From what I remember about the experience, I would give the company an A.”

“I particularly liked the cleanliness with which they did the job and their efficiency as well. They installed 15 or 16 windows, and I have noticed a difference in my heating and electric bill. I would rate them an A.”

“They did windows for me; we got triple-pane windows. They got the job done, and they cleaned up well after their service. They communicated well, too. They deserve an A.”

“We used WindowWorks; they replaced doors for me. They did what they said they were going to do. They replaced two entry doors, and everything has held up well since the work has been completed. The workers were courteous and professional. My husband heard about the company, and that was the first time we'd used them. I would use their services again. They were an A. We had to have them come back because they ordered the wrong door handle. If it hadn't been for that little thing, it would have been an A+, but they did fix it right away.”

“The salesperson from WindowWorks was knowledgeable and friendly, and the work was very good quality. They put in a storm door. That was my first time using them, and I would possibly use them again. They cleaned up well after their service, and they were very respectful of my home. They communicated well with me. I would give them an A because I had no complaints. They were fine.”

“The man who came out to show me examples of what they have done was very, very nice. I felt like he took more time trying to sell me on his product, and I appreciated his time because so many of these businesses don't really care. They don't go out of their way at all, but he did—that's what made me want to go with them. They replaced two windows. They were very respectful of my home and cleaned up well. They communicated well with me. I would grade them an A. They're good—they know what they're doing, and they do a nice job.”

“Everything was fine, great, and OK with the work; they put windows in. I would rate WindowWorks as an A. I liked them.”

“WindowWorks did my windows. That was my first time using them, and I would use them again. They cleaned up well afterward.”

“I liked their response; it was scheduled and confirmed, and everything was on time. The people were pleasant, and they were very clean and neat in the installation. The customer service people were very responsive. They did windows. I found out about their service through my association. They get an A for great service, installers—everything.”

“The door that WindowWorks did for me is very satisfactory. I have no complaints whatsoever.”

“They replaced the patio doors on my house. It was done reasonably quickly, particularly on the day they installed it. They got there at about 9:00, and in three hours, they were done. So that was fine. It was during the summer, and it gets really hot; I didn't have to have the doors off very long. Their customer service was fine; I liked it. They came out and showed us the patio doors. I'm in a townhouse condo, so they had to be pretty much an exact replacement of what I had. I'd give WindowWorks the A grade. I would use them again.”

“I think their service is good. They did windows, and I think, overall, I can rate them well. I would use the company again. They showed up on time, and they cleaned up well after their service.”

“We had windows put in last year toward the end of the summer. They replaced all of them. They came out, they did a proposal, and they explained everything to us. We thought it was a good company. My husband was more impressed than anything, and I trusted him because I don't know that much about windows. We haven't had any problems with the windows. The technicians left our property very clean. I want to say they earned an A, but there's always room for some sort of improvement, so let's give them an A-. He was pleased with them, and I can't think of anything more than that.”
