Sergey was great to work with throughout this project. He came out on time for the initial quote and was very helpful in explaining the different types of windows to me. His crew came out to do the actual installation and they were quick and efficient. They could have been slightly better about cleanup afterwards but really nothing I can complain about. They got the job done in 1 day as promised and they windows look great! Two of the handles for the casement windows didn't quite install right as the set screws were stripped and cannot be tightened down. When I contacted Sergey about this he was already aware of the situation and had put in a repair request to the manufacturer. Should be resolved in the next couple days and couldn't be happier.

I first went to Bestoff's show room on Monument Blvd. in Concord.  I met the owner, Sergey's, son and he showed me several different options and  went into great detail about the pros and cons of each brand/type of window.  His son is young, but very knowledgable.  I made an appointment that day to have Sergey come over to give me an estimate.  He was on time, and very nice.  He measured all my windows, talked to me about how long it would take to manufacture the windows, and how long installation would take.  I had done some research beforehand, and had an idea of how much it was going to cost, and Sergey's estimate was lower than I had expected.  It took a couple of weeks to get the windows made, and then at exactly the time of the morning that Sergey had said his workers would show up, they did.  There were 2 men who took out all my old windows and installed the new ones, and they had it all done, and all cleaned up, in less than 8 hours.  Removing and installing windows has some inherent noise involved, but I work graveyard shift and was able to sleep through most of the installation.  One of the windows I had replaced was a really poorly thought out kitchen window.  Several of my neighbors who had had new windows put in did not have the lousy kitchen window done because the companies they had used had told them it would cost several thousand dollars for just that one window, because it was considered custom (I just considered it stupid and ugly looking).  Sergey told me he didn't anticipate any problems with the kitchen window, and didn't overcharge me for its replacement cost. That kitchen window is now my favorite window of all.  I have no blinds, curtains or anything on it, because the framing for the window is so nice.  I love all of my windows actually.  I am writing this review 9 months after I had the windows installed, and I have had no problems at all with them.  The amount of noise they block out is incredible, and during the summer I really noticed how much cooler it was in the house.  The difference in winter was even more pronounced.  The final cost of the windows was exactly what Sergey had quoted me.

From the estimate to completion of work was around 3 weeks (mostly due to fabrication time with the factory). Serge (the owner) and his crew were very professional. It took 2 installation days to complete the entire project. I will recommend Bestoff to anyone.

The windows are really nice and they did an excellent job installing them. I've referred them to other people. The windows are very well insulated and are tinted, which helps keep the hot sun out in the summer. I thought they did a pretty good job overall. I didn't really have any complaints.
