What started as a two person remodeling company in 1979 has grown into a multi-state construction and home improvement enterprise boasting more than 100,000 happy customers. Delighting our customers, whether they are building new, remodeling or upgrading their home with a new gutter system or roofing installation, is easy to do with the great products we offer and our staff of hardworking and talented employees. Additional DBA: Midwest LeafGuard. Additional service area: Chippewa, Dunn, Eau Claire, Pepin, Pierce, Saint Croix & Trempealeau Counties

"We had a french patio door and 11 windows replaced in our home in Stillwater, Mn. We were extremely pleased with all areas of the process. Although the project was originally planned for mid November and did not start until mid-December and the weather created a few issues, the project was completed in a timely manner once it was started. I was very pleased with our installation crew: Chris, Gabe and Tanner. They worked very hard, were very considerate and punctual. Our sales person, Chris, did an excellent job in explaining the construction and product, Marvin Infinity windows and doors. The QC inspector, Josh was extremely thorough. Very little work had to be redone but Josh made sure every scratch and defect was replaced. We were extremely pleased with the thoroughness of his work. Every member of the Lindus team was professional, polite, informative and respectful. We listen to Andy Lindus on WCCO radio and that was the reason we choose Lindus Construction. The cost of our project was high and more than I expected to pay but we are very pleased with the end result."

Windows questions, answered by experts

Installing energy-efficient windows costs between $325 and $2,000, averaging about $400 per window. You’ll have to consider cost factors like the window’s size, frame material, and type. Labor costs in your area will also impact the overall cost of the project, with window installation professionals charging about $40 per hour on average. Different types of energy-efficient windows include:

  • Single-hung: $150–$2,500

  • Casement: $150–$600

  • Double-hung: $250–$3,000

  • Picture: $200–$650

  • Bay: $480–$1,920

There are many high-quality window companies on the market, although Andersen, Pella, and Marvin continue to be the most popular nationwide. Some brands, like Sunrise and Soft-Lite, are popular regionally but may not be available in all parts of the United States. When comparing brands, look for features like increased energy efficiency, strong and durable materials, and long-lasting and all-encompassing warranties.

Consider energy performance ratings, durability, aesthetics, and ease of maintenance when selecting windows for different environments.

The type of casement window you have depends on where the hinges are located, the number of sashes, the style, and how the windows open. Single casement windows are popular casement windows that use a handle or crank to open. If you have two casement windows side by side, you likely have double casement windows. 

Windows that swing inward can tip you off to having in-swing casement windows, while windows that open from the bottom and swing outwards are top-hinged. If you can open your windows by pushing them outwards like a door, you may have a type of push-out window.

A garden window is about 16 inches to 24 inches deep. This extra space makes room for small potted plants, which is how the garden window, also called a greenhouse window, got its name. Because garden windows jut outward from the house, they need to be installed in a place where they won’t obstruct walkways.
