Allstate Siding & Windows replaced every window in my house. They came in, took all the old windows out, and put the new windows in. They were spotless—inside and out. I never knew they were there. Overall, I'd say they're an A+.
Everything was great. They installed double-paned windows on the house. I'd give them an A+. Everything was wonderful.
We really like the windows. The installers were very nice and polite, and the salesman was excellent. We'll give them an A. We were satisfied.
They got it done quickly, and we were really happy about it. They replaced all of our windows. It was a really good experience. I'd rate them as an A+.
They did good work. The guys that came were really good—A.
They did a good job. They worked on my windows and doors, and they were excellent—an A.
The salesman came and talked and talked and talked. He was a real nice guy. They changed all the windows and the door to the patio. Let's give them an A, but not an A+ because they told us they were going to pay us if they referred somebody, but when my neighbor across the street got her windows done, they didn't do anything with the referral. Our work was great.
They installed new windows. Everything was as promised. It doesn't get any better than that. They promised me an installation time and a price, and they delivered on all that. The work crew was very respectful of my property and plants. I would recommend them to anybody. I'd give them an A+. I was very pleased.
Allstate Siding & Windows replaced most of the windows upstairs in the second story of our house. They did what they said they would do when they said they would do it for the price they said they would do it, so they were honest with me. They're an A+.
They replaced all the windows in my house. The way Allstate Siding & Windows went about doing the work was very efficient. Also, they were very aware of the home environment, so they did things in a very clean manner as far as installation was concerned. I would give them an A+.
