Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home's energy efficiency can also have a big impact on home energy conservation. During the cold winter months, the last thing you want is your heat to leak out of your outdated, drafty windows.
Replacement windows improve your home's insulation, not only making you more comfortable during extreme temperatures, but also saving you some money and helping the environment.
Efficient windows are especially important in Deforest, where winters are long and cold. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $505 each year.

How Installing Energy-Efficient Windows in Deforest Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could benefit you:
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Save money on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Decrease your carbon footprint: By using less energy after you upgrade to Energy Star certified windows, you'll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Deforest
Windows come in different shapes and sizes, so costs and services will differ tremendously. Here are the typical costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
According to our research, the average cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. How much it will cost you depends on several factors, including the location of your home, material, number of windows, size, type and more.
With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Deforest homeowners $505+ per year after replacing single-pane windows.
We advise getting free quotes from several window companies to find the one that works best for you.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the full window, including the frame, sill and trim. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you will likely 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 Deforest, the choice will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Deforest
The EcoWatch Reviews team is different from other 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 using the following methodology:
Service Area
Because this is a guide for Deforest, we gave more points to companies that cover the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Deforest.
Work Quality
We're certain 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 make sure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, quality of parts, professionalism, cost, warranty and more.
Cost
This one is a give-and-take: as with most services, cheap window installers won't always provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a hefty 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
Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Deforest, WI Window Replacement FAQs
How much should a window install cost?
The national average cost of installing a single window is around $600 but can range between $200 and $1,200, based on several factors. The price is usually dependent on the size of the window, the location of your property and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the most common kinds of replacement windows?
The most common types of windows for homes include: awning windows, picture windows, slider windows, bay windows, casement windows, transom windows and double-hung and single-hung windows.
When do I have to use a window installation company?
You should hire a window installation company whenever you need to upgrade your windows. Installing windows is a complicated process that can be difficult and time-consuming, so it's best handled by the professionals.
What time of year is the best time to replace my windows?
Although you can install windows any time of year, warmer weather is often better for replacing windows. In addition, the weather should be dry, because rain can make the installation more difficult.
Should I replace my windows all at once?
If your windows are greater than 20 years old, it's probably time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
