Calculate how much you can expect to pay for window installation and replacement in Sun Prairie, WI using our customized window cost calculator.
Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.
How Installing Energy-Efficient Windows in Sun Prairie Saves You Money
When you switch to energy-efficient windows, you may see several benefits, including:
- Save money on electricity bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll use less energy to heat or cool your home.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Better temperature control in your home: When you reside in a city like Sun Prairie where the summers can be pretty warm, you often have to rely on your air conditioner to keep your home cool. Energy-efficient windows can lower how hard your AC needs to work to cool your home.
Estimated Cost of Window Replacement in Sun Prairie
Windows come in various shapes, purposes and styles, so costs and services will vary tremendously depending on several factors. Below, we describe the average cost and services that you'll find from window installers.
How Much Do New Windows Cost?
Even though the typical to replace a single window is around $600, it can range anywhere from $200 to $1,200. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which carry a higher price tag.
Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $505 a year on your energy bills in Sun Prairie.
Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
In regard to window replacements, in general there are two types that your provider will offer: full-frame and pocket installations.
Full-frame installations are necessary when you want a new style or your window has a lot of rot. With this service, your installers will replace the total window, including the trim, sill and frame. Pocket installations are on the simpler end and won't cost as much, as they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.
If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Sun Prairie, the decision will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Sun Prairie
In our hunt to make your home improvements easier and more eco-friendly in Sun Prairie, the EcoWatch team evaluated many companies before settling on these. We've assessed the best window installation companies in Sun Prairie primarily based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Sun Prairie, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Sun Prairie.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company included in our guide to ensure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, warranty, quality of parts, cost, quality of installation and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Sun Prairie, WI Window Replacement FAQs
How much should a window install cost?
The average cost to install a single window can range from $450 to $650. There are many factors that influence how much it costs, which include the number of windows, how energy-efficient the windows are, local labor costs, styles and sizes of windows, your property's location and the materials used in designing the windows.
What type of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
What services do window installation companies provide?
Window installation companies cover the entire process — from replacing your old windows with brand new ones to cleaning up afterward. Additionally, some companies offer window manufacturing, customization and repairs.
How long does it typically take to install windows?
Because the average installation time is 30 minutes per window, about 16 windows can be installed in a typical 8-hour work day.
Should I replace my windows all at once?
If your windows are greater than 20 years old, you probably need to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
