I saw an advertisement from the company offering wooden larch windows at reasonable prices. I decided to reach out. I first read reviews about GK Okna, and then I asked them a few questions, which didn’t raise any suspicions. I decided to work with them. The measurer came to my place within the day; I made the request in the morning. They installed everything perfectly. A 5-year warranty is quite serious. The installers finished in just 1 hour; they worked very quickly.
