What to Know Before You Replace Your Windows in Wisconsin
Replacing your windows is one of the bigger projects a homeowner takes on, and a few key choices shape how the result looks, performs, and holds up to Wisconsin weather.
Here is what goes into a window replacement project:
- The frame material you choose, vinyl or composite
- The window styles that fit your home
- The glass that stands up to Wisconsin winters
- The company and crew that handle the installation
Vinyl or Composite Frames
One of the first choices you will make is the frame material. Where many companies build on vinyl replacement windows, our composite windows use a solid-core frame that resists rot, chipping, and fading, stays maintenance-free, and does not expand or contract with Wisconsin’s temperature swings.
Our composite frames are also 400% stronger than vinyl, which removes the need for the metal reinforcements that vinyl windows rely on to hold their hardware and resist warping.
Window Styles That Fit Your Home
Replacement windows come in several styles, and the right combination depends on your rooms and how you use them.
A double hung window is a classic, popular choice with a top and bottom panel that both open. Casement windows open outward on a crank and seal tightly against the frame. Sliding windows glide side to side for a simple look.
For rooms where you want more light or dimension, bay windows project outward with a large center picture window and two angled side units, while bow windows create a gentle curved projection. Both are custom made to fit your opening. If a window serves a bedroom or basement, an egress window may be required by code, and for openings that fall outside the standard shapes and sizes, specialty windows can be built to fit.
Glass Built for Wisconsin Winters
The glass inside the frame does a lot of the work in our climate, and it makes up roughly 87% of a window’s surface, so its quality matters more than most people expect.
We use triple-pane glass exclusively, built to outperform traditional double-pane windows on energy efficiency, sound insulation, and durability. Each unit is a full 1 1/8 inch insulated glass package filled with krypton gas and finished with Low-E coatings. Together they keep your home comfortable year-round, cutting heat transfer in the summer and holding warmth inside through the winter.
The Company and Crew Behind the Install
The windows matter, and so does who puts them in. When you compare window companies, it is worth knowing who actually does the work.
We have never used subcontractors. As a window installation company, we handle every install with our own in-house crew, the same approach we have used across more than 15,000 installs in Wisconsin. Our windows are custom-made to fit each opening, and our certified team makes sure code requirements are met.
Our work is backed by some of the strongest warranties in the industry: a 50-year transferable, non-prorated manufacturer’s warranty, a 50-year workmanship warranty, and a 10-year glass breakage warranty, so our customers enjoy long-term confidence knowing both the product and the installation are fully protected.
