How Installing Energy-Efficient Windows in Lake Mills Saves You Money
By upgrading to energy-efficient windows, you can take advantage of several benefits, such as:
- Better temperature control in your home: Energy-efficient windows can decrease how hard your AC needs to work to cool your home.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on energy bills: Because energy-efficient windows reduce the amount of energy needed to heat or cool your home, the switch can help you save around $494 annually on your energy bills in Lake Mills.
Estimated Cost of Window Replacement in Lake Mills
When considering window installation, each company provides different services and prices. Let's take a look at some typical costs and services.
How Much Do New Windows Cost?
On average, Lake Mills homeowners can expect their window installations to range from $250 to $1,200. The average cost is at approximately $600. But costs differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door replacements, which will make your project cost more.
It's important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Lake Mills homeowners $494+ a year when replacing single-pane windows.
We advise requesting free quotes from several window companies to find the right windows and the company that works best for you.
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 is a total window replacement. It involves taking out the old window, the sill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which increase the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won't cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Lake Mills, the choice will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Lake Mills
EcoWatch reviews are different from other reviews since we look at these companies through a sustainability lens. We've assessed the best window replacement companies in Lake Mills mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Lake Mills, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Lake Mills.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company included in our guide to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including quality of installation, professionalism, quality of parts, warranty, cost and more.
Cost
This one is a give-and-take: as with most services, cheap window companies may not provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Lake Mills' climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Lake Mills window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Lake Mills, WI Window Replacement FAQs
How much does a window install cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is typically influenced by the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which kind of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
Can you install your own windows?
Although it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
Should I replace my windows all at the same time?
If you're upgrading your windows to save on your energy bills, replacing all of the windows together is the only way to gain that benefit. However, if you have only one or two windows that are broken or leaky, you can replace just those.
