Window Replacement That Feels Clear From the Start
New windows can make your home more comfortable, more efficient, and easier to live in, but choosing the right products should not feel like sitting through a long, high-pressure sales pitch. At Heins Contracting, we keep the process straightforward. We review your openings, talk through your goals, explain your options, and provide clear pricing without making the decision harder than it needs to be.
We install replacement windows for homeowners across Southern Wisconsin using trusted products from Andersen and Polaris. With factory direct pricing, product-specific warranties, and a 10-Year Workmanship Warranty, you get a window project built around performance, value, and the realities of Wisconsin weather.
Windows We Install on Southern Wisconsin Homes
The right window material depends on your home, your budget, and what you want from the finished project. Heins Contracting offers several window material options, and our team can help you compare them during your estimate.

Aluminum-clad wood-frame windows pair a warm wood interior with durable exterior cladding that helps protect against weather exposure. They are a strong option for homeowners who want the look of wood inside with added exterior performance and lower maintenance.

Fiberglass windows are a premium option known for strength, stability, and long-term performance. They resist expansion and contraction with temperature changes, making them a smart choice for homeowners who want a durable frame with a refined look.

Wood windows bring natural character, warmth, and classic detail to a home. They are often chosen for historic homes, traditional architecture, or projects where interior finish options and authentic styling are important parts of the design.

Composite windows offer a durable alternative to traditional frame materials, with strong performance and a clean appearance. They are a good fit for homeowners who want stability, energy efficiency, and a low-maintenance window option.
Window Replacement, Installation, and Repair Services
Heins Contracting provides window installation for both existing homes and new construction projects. We also offer window repair when it makes sense, given the window's condition. Not every issue requires a full replacement, and we will tell you when a repair is the more practical option.
If your home has been affected by hail, ice, wind, or severe weather, our team can assess the damage and determine whether your windows need repair or replacement. In some cases, damaged windows can be addressed as part of a larger storm restoration project involving roofing, siding, or gutters.
We also offer financing options for qualified homeowners, including same-as-cash and extended payment options. Qualifying replacement windows may also be eligible for Energy Star-related federal tax credits, depending on the products selected and current IRS guidelines. Your tax professional can confirm what applies to your project.Â
We See Through Walls
The most common calls we receive about windows are about water leaks. Because water leaks around windows are not always easy to trace from the surface, Heins Contracting uses infrared scanning when needed to identify areas of concern without unnecessary demolition. Just as importantly, this process can help confirm which areas are not part of the problem, so you are not paying for work your home does not need.

Window Styles and Customization Options
Frame material is only one part of the decision. Heins Contracting also offers a range of window styles, configurations, colors, finishes, and grid patterns to help your new windows fit the look and function of your home.
Double-Hung Windows: A popular option for many homes, double-hung windows offer classic style, easy operation, and ventilation from the top or bottom sash.
Casement Windows: Casement windows open outward with a crank and are well-suited for areas where you want strong ventilation and a clear view.
Picture Windows: Picture windows do not open, but they bring in natural light and work well in rooms where views and efficiency are priorities.
Sliding Windows: Sliding windows open horizontally and can be a practical fit for wider openings or rooms where easy operation matters.
Bay and Bow Windows: These window styles add dimension, natural light, and curb appeal while creating a more open feel inside the home.
These are just a few of the style options we offer. During your estimate, we can walk you through the styles that make the most sense for your layout, goals, and budget.

Excellent company to deal with! Kyle was very knowledgeable about the roofing products and what we should expect. Aston and his crew had the roof completed under 6hrs. and did an excellent job on the clean up. Highly recommend, and their prices are very reasonable!
I hired Hein’s Contracting to replace siding on my insurance office in Dodgeville and they were amazing to work with on the project! Very detailed estimate, great communication and extremely organized. I worked with DJ Burris on the estimate and Josh was the project manager- I highly recommend them!
Heins Contracting recently installed new windows and siding on my home. They were professional, efficient and communicative to work with from sales rep DJ Burris, Project Manager Josh Smith and both the siding and window crews that completed the work on my home. They left behind no mess! The work was completed on schedule and within budget. I love how beautiful my house looks now!
