Good specialists, selected and assembled the right windows. Gave a guarantee. It has its own specialists who can adjust the windows if necessary.
Completely unreliable company. The window mechanism broke down after a month of use, we fought for the replacement for more than a month. The window has been replaced, but the damaged exterior and interior trim has not been repaired, it has been ignored for 4 months. If you want to live in peace, choose a reliable company.
I applied for door adjustment because in the cold season, outside doors pass through the cold. Within 1 month did not contact the master to arrange a visit. Then stopped answering calls.
