Window & Door Installation
Set tight, flashed right,
warmer all winter.
Replacement windows and exterior doors in Duluth and across Northern Minnesota — old units pulled, every opening flashed and air-sealed in the right order, then trimmed to match the house. The way a window stops leaking heat is the install, not the sticker.
The draft
You feel it before
you see it.
Drafty old windows and doors bleed heat all winter, and the cause is usually hiding behind the trim: an opening that was never flashed right the first time. A new unit set into a bad opening leaks just as much as the old one — the gap behind the trim is where the cold comes in.
So we open it up and fix the part you can't see. We pull the old units, get the rough opening flashed and air-sealed correctly, set each window and door plumb, and trim it back in to match. Here's what's in the job:
- Removal of old units. Out come the old windows and doors — and we open the rough opening to see what the last install left behind.
- Proper flashing & air-sealing. The opening flashed in the right order and the gap sealed, so wind and water stay out — the step most drafts trace back to.
- Window & door install. Each unit set plumb and level into an opening sized to fit it, not forced into a guess.
- Interior & exterior trim. Finished inside and out, so the opening reads as part of the house, not a patch.
- Match to the existing home. New units lined up to the style and finish already there — they sit alongside the old ones, not against them.

Window & door questions
Answered.
Why are my new windows still drafty after a recent install?
Almost always the flashing and air-sealing, not the window. A unit can be a good window and still leak heat if the rough opening was never flashed in the right order or the gap behind the trim was left unsealed. When we pull old units in Duluth and Hermantown, that's the most common thing we find and fix.
Do I have to replace every window at once, or can I do a few at a time?
You can do as few or as many as you want — we quote to the exact count and type of unit, so a three-window job and a whole-house job are both priced honestly. Many homeowners start with the worst north- and west-facing openings that take the brunt of the wind off Superior.
Will the new windows and doors match the rest of my house?
Yes. Matching the existing home is part of the job — we trim inside and out to fit the original style and finish so the new units don't read as add-ons. If you're swapping a few openings, they'll sit alongside the old ones without looking like patches.
Do you supply the windows and doors, or do I buy them?
We handle it. We measure every opening ourselves and order units sized to what's actually there, which is the part that goes wrong when windows are bought to a guess. You're welcome to tell us a brand or look you want, and we'll quote to it.
How long does a window and door job take?
It's scoped up front — the schedule depends on the count and type of unit and how long the order takes to come in, so we set real dates with you before we start rather than quote a generic week. ProCon is licensed in Minnesota under #QB807406 and insured.
