At SK Windows & Doors, we believe that home improvement should be a comfortable, positive experience — not a high-pressure sales pitch. Since 1990, we have been serving homeowners in Jefferson, Fort Atkinson, Lake Mills, and the surrounding communities with a simple philosophy: treat every customer like a neighbor.
Based in Jefferson, Wisconsin, SK Windows & Doors is locally owned and operated, meaning the money you spend with us stays right here in our community. Whether you need a single garage door repair or a full home exterior makeover, we are dedicated to providing the highest quality craftsmanship at a fair, honest price.
The story of SK Windows & Doors began in 1990 when Shawn Krause founded the company with a focus on overhead garage doors. As the business grew and our reputation for reliable service spread, we recognized a need in Jefferson County for a window and siding contractor that homeowners could truly trust.
In 1995, Lloyd Gleisner joined the team, and together, Shawn and Lloyd expanded the company's services to include residential window, door, and siding installation. Over 30 years later, we have grown into the area's premier exterior remodeling company, but we have never lost sight of our roots.
SK Windows & Doors is still the team you call when you want it done right, the first time.
In an industry full of high-pressure tactics and fly-by-night contractors, we pride ourselves on being different. Here is what you can expect when you work with SK Windows & Doors:
We don't chase storms, and we don't travel all over the state. SK Windows & Doors chooses to work within a roughly 30-mile radius of Jefferson because we love our community. By keeping our service area local, we can respond quickly to your needs and build lasting relationships with our customers.
When you hire SK Windows & Doors, you aren’t just hiring a contractor; you are hiring a neighbor who cares about the result. Strong family and community values are important to us, and we support community and school programs as well as youth leadership programs.
