The company itself may be good, the windows were installed on time! But installers are a wild horror! From the beginning, I noticed one jamb, they came to fix everything by running on otiabis' and made it even worse! On the street side, they left a gap of 2-3 mm between the window and the window sill, I covered it with sealant myself! When I began to trim the foam, I noticed that after dismantling the old frames, they did not clean the surface and foamed directly onto the garbage! There is a draft from all the window sills! There was a void under the slopes, the joints did not miss at all, and a through hole was left near the balcony door! In general, you need to dismantle all the slopes and re-foam! Everything was done very carelessly! (The installers are two big Russian men, maybe in combination with a puny mustachioed one)))
