Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home's energy efficiency can also have a considerable impact on home energy conservation. Outdated windows can cost you in electricity bills. In fact, the Department of Energy estimates that 25-30% of your house's heat or cool air could be lost through your windows.
Replacement windows improve the insulation in your home, not only making you and your family more comfortable during the summer and winter, but also saving you money and helping the environment.
Because windows are so important for your home, selecting the best company for you is a big decision to make. That's why the EcoWatch team has put together this list of the best window installation companies, so you can make an informed decision more easily.

How Installing Energy-Efficient Windows in Dover Saves You Money
By switching to energy-efficient windows, you can enjoy several benefits, including:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Dover, that's about 497 pounds per year on average.
- Save money on electricity bills: After you install energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your house.
Estimated Cost of Window Replacement in Dover
Let's take a look at the cost of updating your windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
The national average cost to install one window is about $600 but can range from $200 to $1,200. Costs will differ significantly based on your location, the number of windows you need, the current condition of your home and the quality of your products. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. Additional services will increase your overall project costs.
It's important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Dover homeowners $439+ a year when replacing single-pane windows.
We advise getting free quotes from several window companies to find the one that works best for your budget.
What Services do Window Installers Offer?
The first thing to ask yourself when considering a window replacement is: Do you want a full-frame installation or a pocket installation?
A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. As this type of installation requires more time, it will cost more than a pocket installation. A pocket installation involves installing a new window within the old frame. This means instead of removing the whole window and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window replacement company will be able to help you understand what's best for your needs. In Dover, the decision will mostly depend on the age of your windows and if there's any damage. Wood can decay if not properly maintained over the years, so it's good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Dover
The EcoWatch Reviews team differs from other reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Dover, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Dover.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including cost, warranty, quality of parts, professionalism, quality of installation and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a serious investment, so you'll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Dover, WI Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost to install one window is around $600 but can range between $200 and $1,200, based on several factors. The price is often influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
Which type of window should I get?
A window's energy efficiency depends on a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
Do I really have to use a window installation company?
Unless you have experience with home improvement projects and have all the tools you need to replace your own windows, we recommend hiring the pros. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer option.
When is the best time of year to replace windows?
Though you can install windows any time of year, warmer weather is generally better for installing replacement windows. In addition, the weather should be dry, since rain can make the installation more difficult.
How often should you replace windows?
Windows generally have a lifespan of around 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have an expert take a look at them to determine if they need any repairs or replacements.
