Replacement Windows

A home that feels warm and bright for your whole family.

In a Wisconsin winter, bad windows turn rooms cold, dark, and drafty. The right windows bring back the warmth, fill your home with natural light, and make every room a place your family wants to be.

Windows We Install

Comfort, Light & Living

The rooms you avoid can become the rooms you love.

In a Wisconsin winter, old windows leave whole rooms too cold to sit in. The drafts never quit, the glass fogs, and the blinds stay shut against the chill. New windows fix the cold at the source, so your home feels warm and even from one room to the next.

They change how a room feels, too. Natural light pours back in, and you can finally throw the blinds open and enjoy the sun without cooking yourself out of the room. That is the difference between a house you just get through in January and a home your family loves in every season.

Signs it's time

→Cold spots and drafts you can feel
→A room too cold to use in winter
→Fog or moisture between the glass
→Windows that stick or won't stay open
→Rooms that stay dark, or bake in the sun
→Outside noise you can't shut out

Signs It's Time

You've seen these before. Maybe on your own home.

When a window starts to go, it shows. This is what worn-out and failed windows actually look like, and exactly what new ones put an end to.

Cloudy fog trapped between the panes of a window with a failed seal — **Fog trapped in the glass**The seal failed. No cleaning brings the view back, only new glass does.

Frost and ice built up on the inside of an old window in winter — **Ice on the inside**Worn-out windows give up in a Wisconsin January. Cold gets in, heat leaks out.

Rotted, peeling wood at the corner of an old window frame — **Rotted, soft wood frames**Water got in years ago. Rot doesn't stop on its own, it spreads into the wall.

Torn window screen with ripped mesh and a bent frame — **Torn, broken screens**Ripped mesh and bent frames. The fresh air comes with everything else, too.

For the spec-minded: the performance behind the comfort

The comfort you feel comes from the glass. We build every window on a North Star package engineered for our Wisconsin winters. Here is what makes it perform, and why each piece keeps your home warm, quiet and bright.

Center-of-glass U-Factor0.20How well the glass holds your heat in. Lower is better. This 0.20 is the glass on its own; the whole-window NFRC number runs a bit higher, and 0.20 puts this double-pane glass in triple-pane territory.

Solar Heat Gain0.27Enough winter sun to help warm the room, without the summer glare cooking you out of it.

The glassTriple-silver Low-ETriple-coated silver Low-E over low-iron glass. Clearer view, more daylight, less heat lost through the pane.

The sealDual-sealedStainless-steel warm-edge spacer with a dual seal, backed by a lifetime seal warranty, so no fog between the panes down the road.

One straight answer on that U-Factor: 0.20 is the center-of-glass number, the glass by itself. Whole-window NFRC always runs a little higher once you count the frame, and we will hand you the exact NFRC label for the package you choose. We would rather show you the real number than a marketing one.

Behind the glass: an insulated frame with composite reinforcements stronger than aluminum, built on virgin vinyl that will not yellow or warp. Triple-pane is available when you want the absolute top of the line, and it is the package to ask about if you want the whole window to clear the ENERGY STAR Northern-zone bar.

The Low-E glass, warm-edge seal and lifetime warranty behind your comfort, straight from the manufacturer.

View the glass

DEV: wording now says "ENERGY STAR-rated packages available" + "match you to a package" (not a blanket "every window is certified"), and the U-Factor row/straight-talk note label 0.20 as center-of-glass and point the whole-window buyer to the triple-pane package, all defensible as written. Still: pull the actual NFRC/CPD certificate number for the exact package(s) Northcraft sells so we can name the whole-window U-factor and confirm which config carries the ENERGY STAR Northern-zone mark. SHGC 0.27 and U 0.20 are placeholder center-of-glass figures, replace with North Star's published NFRC/CPD numbers for the exact package Northcraft sells.

Windows FAQ

Common questions.

Why don't you show window prices online?

Because a real window price depends on the count, sizes, styles, frame material, and glass. It varies too much to fake a number on a page. We'd rather give you a real, exact quote than a range that misleads you. For real ballpark ranges and what drives them, read our guide to what replacement windows cost in Wisconsin.

How long does window replacement take?

Most projects are completed in one to two days depending on the number of windows.

Do you offer financing?

Yes, including 0% for 24 months on qualifying projects. Pre-qualify with no impact to your credit.

What warranty do I get?

Both workmanship and manufacturer warranties, with extended coverage on higher tiers.
