Replacement window colors

Whether you’re looking for a modern, classic, or rustic look for your replacement windows, we’ve got exterior and interior color options to fit any Wisconsin home aesthetic.

Modern window colors:

Modern windows typically feature clean lines, minimalistic design, and an emphasis on functionality. They tend to have a sleek appearance and are often made with materials like metal, glass, or composite materials. Window colors that fit this category include cool tones such as white, gray, black, and metallic finishes.

Classic window colors:

Classic windows are characterized by their traditional designs and timeless appeal. They often feature detailed moldings and ornate patterns that add a touch of elegance to any home. Window colors that might fit under this category include warm tones such as cream, beige, brown, and wood finishes.

Rustic window colors:

Rustic windows have a natural and rugged appearance that complements homes with a country or farmhouse style. They typically feature wood frames and may have decorative hardware or distressed finishes. Window colors that might fit under this category include earthy tones such as green, brown, or red, as well as natural wood finishes.


When to replace your windows

Consider replacing your windows if you’re experiencing drafts, mold, cracking, warping, or a suddenly increased energy bill. Some windows have a shorter lifespan than others, but the rate at which windows need to be replaced is highly dependent on how they were installed. Poorly installed windows will need to be replaced much more often than windows that are properly installed, reinforced, and insulated. Pick a window brand and contactor with credibility. Going the cheap route with window replacement usually results in more frequent repairs.


7 signs your windows need to be replaced

  1. Drafts or leaks: If you feel a draft coming from your windows or notice water leaks, it's likely that the seals around the window have failed and need to be replaced.
  2. Condensation: If there’s condensation between the panes of glass, it means that the seal around the window is no longer airtight and needs to be replaced.
  3. Difficulty opening or closing: If your windows are difficult to open or close, the problem may be worn-out parts such as the balance system or sash.
  4. Rot or damage: If you notice rot or damage around the window frame or sill, it's likely that the window needs to be replaced.
  5. High energy bills: If your energy bills are higher than usual, it could be due to inefficient windows that aren't properly insulating your home.
  6. Noise: If you can hear a lot of outside noise when your windows are closed, it may be time to replace them with more soundproof windows.
  7. Age: Windows generally have a lifespan of around 15-20 years. If your windows are older than that, it may be time to replace them with newer, more energy-efficient models.

Frequently asked window questions

How do you know when you should replace your windows in Wisconsin?

If your windows is cracked, warping, molding, or causing drafts, you most likely need to replace your windows. Sometimes drafting is caused by poor insulation and not your window itself - be sure to consult with a window expert before pulling the trigger on a full window replacement project.

How much does window replacement cost in Wisconsin?

On average, window replacement will cost somewhere between $750 and $1,350 per window in Wisconsin. Price usually depends on the size and style of the window.

Can you replace your windows in the winter in Wisconsin?

Yes. The cold weather from the winter months is often what signals a homeowner their windows are causing a cold draft. If you notice your electric bills are higher this winter compared to previous years, this is a sign your windows may need to be replaced.

Is it cheaper to replace all your windows at once?

Yes. Usually, the more windows you replace, the less each window will cost. For example, the per window cost for 1 replacement window will be higher than the per window cost if you replace 15 windows.
