They're cognizant of the house and of making everything look the way it's supposed to. They're very personable. I ask for the same crew back every time. I can't afford my whole house at once, and they have been very receptive about that. They're just great guys. It's Kevin and Kyle, and they're the best of the best. We're in New England, and we had a terrible winter. We started in November with measurements and stuff, but we couldn't actually start the job until January because of all the snow. They came, they did a few, and they're actually at my house today. I'm going to have them back in the fall because this is the summer home that they're doing, and I can't get here all the time. They've been very receptive to scheduling when my schedule is available, so it's been great. I would definitely say they get an A. The other person that's been very helpful is Karen at the main office.
They replaced the windows. I would recommend them to a friend or neighbor. I didn't have any issues with them when they were out. I'd give them probably an A. They did what they said they were going to do, and they did a good job.
Well, it was done when they said they were going to do it, and it was done in a day. It was 11 windows. My son had used him, and he recommended him, so they're actually going to do more work for him next month. I would have more work done with them if I needed more. I'd give them an A.
We had a very positive cleanup and everything. He had left some spots where the air was coming in, and he came right back when we called them and sealed all my windows. I would use them again. We had no complaints. I would say they're an A.
Castle replaced windows. The guy that came to install them was very neat and very clean. I had some paint left on the trim outside. They painted the trim after they put the window in because it was a big front window. They painted all underneath and on top of it. Before he left, my door had blown open, and he screwed it back in for me—the piece that came out—which he didn't have to do at all. I said, 'Oh, thank you so much,' and then I went to tip him for doing that. He said, 'Oh, absolutely not. I can't accept that.' I said, 'Oh my God, thank you.' So it was very positive. I'd give them an A.
They have done windows for me before, about three or four years ago. There was just one more, a picture window, that I had to wait to do, so I've called them back. I'm a return customer. It was just windows they did before—replacement windows, and this is a picture window where the others were just double-hung. I would give them an A.
That was a year ago, and everything was fine. They just replaced a window. That was my first time using them, and they did a good job. I would use them again.
They showed up fairly promptly. They did the work, they cleaned up afterward, and they were pretty much in and out—no problem. Everything was good. That was my first time using them. I would use them in the future. I would say they're an A.
Castle Windows did a sliding door for me, and it was excellent. I can't praise them enough. When I saw the way they worked, it was unbelievable. They were the best—A+. I was very satisfied.
I liked Castle's service. I've worked very well with them, and I love the way it looks. My windows were very old, and they needed to be done, so it was good. I thought they were excellent. They always have been an A+.
