Calculate how much you can expect to pay for window installation and replacement in Cottage Grove, 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 Cottage Grove Saves You Money
When you switch to energy-efficient windows, you may see several benefits, including:
- Better temperature control in your home: When you live in a place like Cottage Grove 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 decrease how much cool air is lost through your windows when cooling your home.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
- Save on energy bills: Installing energy-efficient windows lowers your energy bills by about 12% since you need less energy.
Estimated Cost of Window Replacement in Cottage Grove
Each window replacement company provides various services and has varying prices depending on a few factors.
How Much Do New Windows Cost?
According to our market research, the national average cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. These estimates are based on the specifics of your installation, like number of windows, type, size, material, the location of your home and more.
With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Cottage Grove homeowners $505+ each year after replacing single-pane windows.
Getting free quotes from several companies is the best way to find out which one is right for you.
What Services do Window Installers Offer?
There are typically two types of window installation services: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the full window, including the sill, trim and frame. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you're unsure which window installation service you should get, your installer should be able to assist you. Typically, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Cottage Grove
The EcoWatch Reviews team is different from most reviewers, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Cottage Grove, we gave more points to companies that serve the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Cottage Grove.
Work Quality
When picking new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have good feedback about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window companies may not provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you'll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Cottage Grove's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Cottage Grove window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
