20 Best Window Companies in Sun Prairie, WI (2025 Reviews)

How Installing Energy-Efficient Windows in Sun Prairie Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to take the plunge and make the switch:

• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
• Reduce your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 715 pounds per year on average.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Save on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% since you use less energy.

Estimated Cost of Window Replacement in Sun Prairie

Each window replacement company provides varying services and has varying price points depending on several factors.

How Much Do New Windows Cost?

Generally, Sun Prairie homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. These estimates are based on specific characteristics of your installation, including material, the location of your home, number of windows, size, type and more.

Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $505 a year on your energy bills in Sun Prairie.

How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

Generally, there are two kinds of window installation services companies provide: full-frame and pocket installations.

A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re still debating which type of installation you should get, you can talk to your installer and get their advice. The choice mostly is influenced by how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Sun Prairie

EcoWatch reviews are different from other reviews, as we assess these companies through a sustainability lens. We have reviewed the top window replacement companies in Sun Prairie mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Sun Prairie area so you can find the right window installation company near you.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company featured in our guide to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have good things to say about their service from a certain window installation company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installers are not going to provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a substantial investment, so you’ll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Sun Prairie’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Sun Prairie window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
