I replaced the old wooden frames with plastic ones. The guys are friendly and eager to provide the best service. They work well and are unobtrusive. They were very attentive, took my wishes into account, and promptly resolved our issues. Now, our whole family can't get enough of it; we'll celebrate the New Year in warmth, comfort, and with beautiful windows. Thank you to everyone who helped us choose the optimal option for us. I recommend them for collaboration!
