One of my colleagues told me that he had ordered windowtech windows and doors . He was so enthusiastic about the service that it made me think that I should also replace the old windows in my house. I decided to do the same and opted for double-glazed windows from them. They offered me a great option for our climate. The order was placed quickly, and the delivery didn't take long - everything was delivered on time. I agreed in advance with the installers, although windowtech also offers installation.
