Why you can trust EcoWatch
Although green energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's efficiency can also have a large impact on home energy conservation. If you have old or damaged windows, your AC or heating system could be working overtime to heat or cool your home. This means higher energy bills.
Replacement windows improve your home's insulation, not only making you and your family more comfortable during extreme temperatures, but also saving you money and helping the environment.
As windows have such a considerable impact on your home, picking the right company for you is a big choice to make. That's why the EcoWatch team has created this list of the best window installation companies, so you can more easily make an informed decision.

How Installing Energy-Efficient Windows in Watertown Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could help you:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Save on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
- Better temperature control in your home: Living in a warm place like Watertown usually means relying on your AC to keep your house cool. Energy-efficient windows can lower the amount of cool air lost through your windows when cooling your home.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Watertown
Each window installer provides varying services and has varying prices based on a few factors.
How Much Do New Windows Cost?
Typically, Watertown homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. But costs vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will make your project cost more.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially during the winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Watertown homeowners $504+ a year after replacing single-pane windows.
Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first step when considering an installation is to decide whether you need a full-frame or pocket installation.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation means replacing a window without taking out the entire frame, which is usually cheaper than a full-frame installation.
If you're still debating which type of installation you need, you can consult with your provider and get their advice. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Watertown
EcoWatch differs from most reviewers because we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Watertown and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the Watertown area so you can find the right window installation company near you.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive feedback about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installers won't always provide the most quality service. Still, 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
Protecting your investment in new windows is important. That's why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Watertown's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Watertown window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Watertown, WI Window Replacement FAQs
What is the typical cost to install new windows in a home?
The typical cost of replacing one window can range from $450 to $650. There are several factors that affect the price, such as the number of windows, local labor costs, the materials used in designing the windows, styles and sizes of windows, how energy-efficient the windows are and your property's location.
What are the most common types of replacement windows?
The most common kinds of windows for homes are bay windows, picture windows, awning windows, slider windows, transom windows, double-hung and single-hung windows and casement windows.
Can I replace my own windows?
While it is possible to install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
When is it time to replace your windows?
Windows generally last about 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 see if they need any repairs or replacements.
Should I replace all my windows at once?
If you're upgrading your windows to get more efficient windows, replacing all of your windows at once is the only way to see a noticeable difference. However, if you have just a few windows that are damaged or drafty, you can replace just those.
