TWS Remodeling has been the window contractor Twin Cities homeowners trust for 25 years, licensed in Minnesota under #BC773859. Here's what we tell everyone comparing contractors: on a Minnesota window job, who installs the window matters more than the brand. A premium unit set into a sloppy, under-flashed opening leaks air by the second winter; a mid-priced vinyl window air-sealed correctly holds for 20-plus years. The same employee crew that measures your openings sets the glass. Call (612) 445-4352 for a free in-home estimate.

This page isn't a checklist of questions to grill an installer with. Our companion guide to vetting a Minneapolis window company already covers those. This page is about what a window contractor actually does on your house, why the flashing and air-seal details are where jobs succeed or fail in this climate, and how we run a job start to finish so nothing gets handed off to a crew you never met.

What a Window Contractor Actually Does (and Where the Job Is Won)

A window contractor's real work happens in the two hours you never watch: pulling the old unit, checking the rough opening for rot and square, air-sealing the gap, and flashing the exterior so water sheds away from the wall instead of into it. That sequence, not the window brand, is what decides whether the room stays warm and dry through a Minnesota winter. After 25 years installing across the Twin Cities, our read is blunt: the single most common failure we're called to fix is a window that was dropped in fast with foam and caulk and no proper flashing. Much of the older Minneapolis and St. Paul housing stock, the pre-1940 bungalows in Longfellow and Nokomis, the story-and-a-halves near the lakes, has rough openings where nothing is square. A contractor who quotes over the phone without seeing those openings is guessing. We measure every opening in person, flag out-of-square headers and rotted sills before we quote, and price the real job instead of the easy one. Want a straight read on your openings?

Employee Crews vs. Subcontractors: The Difference That Shows Up Three Winters Later

Here's how a lot of the window industry actually works in the Twin Cities. A company runs the ads, closes the sale, then hands your install to a subcontracted crew they found that week. The person who quoted you is never the person on your roofline in February, and when a seal fails in year two, accountability evaporates because the crew has already rotated on to the next job.
"The company that quotes you should be the company that's standing behind the work when something goes wrong three winters later. If those are two different companies, you have a problem the low bid never mentioned."
We don't work that way, and it's the single biggest thing to check when you compare window contractors. Our own employees do the install, start to finish. That's been the standard since Tyler Ganz founded the company in 2001. It's also why our reviews describe the same crew arriving on time, finishing most homes in a single day, and cleaning up before they leave, one homeowner with a 1948 house specifically noted that our flashing matched the existing detail perfectly because the installers knew what they were doing. One company measured it, installed it, and owns the result.

Is a Window Remodeling Company Different From a Window Contractor?

In practice the terms overlap, but there's a useful distinction. A window remodeling company handles the whole exterior envelope, not just the glass, so when your windows go in, the same crew can address the siding, trim, and flashing they tie into. That matters more than it sounds. On an older Twin Cities home, a window opening shares its water-shedding details with the siding and fascia around it, and splitting that work across two companies is where the seams leak. TWS is a full-envelope remodeling company that installs windows, doors, and siding with one crew and one point of accountability. We're a GAF certified installer on the roofing side, which is the same standard of manufacturer-backed workmanship we bring to the building envelope as a whole. Several of our longtime customers came to us for windows and then had us back for siding, doors, and roofing, because a single contractor who already knows the house is easier to trust than a fresh crew every time. If your project touches more than the glass, our full window replacement services and door and siding work run through the same team. Ready when you are. Call (612) 445-4352 and we'll walk the whole envelope, not just the windows.

How to Choose a Window Contractor in Minnesota

Choosing a window contractor in Minnesota comes down to fit for this climate, not just price. Three things separate a contractor who'll still be standing behind the work in year five from one who won't. 1. **They install with their own employees.** Ask directly: do your crews install, or do you subcontract? A vague answer is the answer. Subcontracted installs are the source of most window problems that surface a few winters later. 2. **They're licensed in Minnesota, and they'll hand you the number.** A residential building contractor here must be licensed through the Department of Labor and Industry. Ours is #BC773859, and you can verify any number on the state's public lookup in about a minute. The license carries the bonding and insurance that stands between you and a lien on your home. 3. **They've installed in the Twin Cities specifically, for years.** A contractor who has only worked milder climates doesn't know how Minneapolis freeze-thaw punishes a lazy flashing detail. Local time is what tells them where the shortcuts show up later. When you're past that point, the crossover to replacement is real seal failure, drafts you can feel on a January night, or sashes that won't hold open. That's when the contractor you pick starts to matter. We'll give you a straight read on which situation you're in at the in-home estimate before anyone talks numbers.

Why Twin Cities Homeowners Choose TWS as Their Window Contractor

The crew on your property is our employee crew, and they've been detailing Twin Cities windows long enough to know where a shortcut turns into a callback three winters later.

We work both sides of the river, so the same crew handles residential window replacement across Minneapolis and St. Paul under one warranty. A Twin Cities address never changes who shows up.
