Double-hung windows
The classic choice. Both sashes open for easy cleaning and great ventilation.
Windows & Doors · Our specialty
Tight, warm, and done right the first time.
We've installed thousands of windows across northwest Minnesota. We measure carefully, source quality product, and install with a team that takes pride in its work.
What we install
Every window type, every door style, measured and installed by our team.
Casement & awning
Crank-operated windows that seal tighter than most, ideal for energy efficiency.
Picture & bay windows
Big, beautiful views. We frame them perfectly and seal them so no cold air sneaks in.
Slider windows
Simple, durable, and low-maintenance, great for wider openings.
Entry doors
Steel, fiberglass, or wood. A new front door improves security, curb appeal, and energy efficiency in one shot.
Patio & sliding doors
French doors, sliding glass doors, and multi-panel options for back and side entries.
Storm doors
An affordable layer of protection that extends the life of your entry door and cuts drafts.
Full-frame replacement
When the frame itself is rotted or damaged, we replace everything, properly flashed and sealed.
Energy efficiency
Minnesota winters are no joke. Your windows shouldn't be either.
A drafty window doesn't just waste heat. It costs you every month. We spec the right glass package for your climate, budget, and how long you plan to stay in the home.
Triple-pane glass
Three layers of glass with two insulating gaps, which dramatically cuts heat loss in Minnesota winters.
Low-E coating
Reflects infrared heat back in during winter and keeps solar heat out in summer.
Argon gas fill
Denser than air, argon slows heat transfer through the pane. Standard on our mid-grade and up.
Warm-edge spacers
Reduces condensation at the edge of the glass and improves the overall U-value.
Why Stonegate
Experience that shows up in the details.
Measured by the people installing them
We don't subcontract. The person who measures your windows is on the team that installs them, which means the fit is right the first time.
Licensed & lead-safe certified
Minnesota licensed contractor (BC809149) and lead-safe certified for work on pre-1978 homes.
Manufacturer warranty + our workmanship guarantee
Every window comes with a manufacturer warranty. Our install work is guaranteed: if it leaks or drafts because of how we put it in, we come back and fix it.
