Last spring Big Sky Exterior Designs replaced 14 windows in our 1980’s house with Simonton 5500 series windows. Our old windows leaked badly, and, in some areas, had rotted out the sill & supporting studs. Mark and his crew rebuilt those areas and installed the new windows plus put maintenance free trim on the outside. On the inside, new wood moldings were installed. The workmanship was excellent. When winter arrived, we found the house seemed much warmer and our power bill was less even though this winter was colder than last.

One of the double-hung windows cracked for unknown reasons. Rob of Big Sky Exterior Designs immediately ordered a new window free of charge, and we replaced it before the end of the year. We couldn’t be happier with our new windows.
