Your leading experts for Window Replacement

Blue Line Exteriors offers top-of-the-line windows built to beat Minnesota’s weather extremes. We work with window manufacturers whose windows have been engineered and finely tuned to perfectly combat the coldest winters and the hottest summers.

Roofs and siding near the end of their lifespan are more susceptible to storm damage. If you’re in need of an exterior restoration, we’ll promptly make your home water tight before the next storm. Since we have an in-house storm damage repair crew, you won’t have to waste valuable time waiting for subcontractors to become available.

We offer:

  • Free design consultations and estimates
  • Customizable windows options
  • Competitive prices on every project
  • Industry – leading warranties
