Why you can trust EcoWatch
Although eco-friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house’s efficiency can also have a big impact on home energy conservation. If your house has outdated, drafty windows, your HVAC system could be working overtime to heat or cool your home. This means spending more on electricity bills.
Luckily, saving you energy with upgraded windows also aligns with our goals of conserving energy and the resources it takes to generate it.
Efficient windows are especially important in Watertown, where winters are long and cold. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $504 per year.

How Installing Energy-Efficient Windows in Watertown Saves You Money
By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, including:
- 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.
- Save on energy bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged.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.
- Reduce your carbon footprint: By using less energy after upgrading to energy-efficient windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Watertown
Windows come in different shapes and sizes, so costs and services will vary remarkably. Here are the average costs and services that you’ll find from window installation companies.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range from $200 to $1,200. Costs will differ significantly depending on the quality of your products, the current condition of your home, the number of windows you need and your location. Many window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase overall project costs.
It’s also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star estimates that switching out the windows on your Watertown home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
How much your window installation costs will also vary based on the kind of window material you choose for the frames. Wood windows are usually the most expensive, though it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
When it comes to window replacements, in general there are two types that your provider will offer: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has a lot of rot. With this service, your professionals will replace the complete window, including the sill, trim and frame. Pocket installations (or retrofits) entail 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 damage or rot, you should opt for a full-frame installation instead.
If you’re not sure which kind of window installation service you should get, your installer can advise you. Generally, the choice is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Watertown
In our search to make your home improvements easier and more eco-friendly in Watertown, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company featured in our guide to make sure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have good things to say about their service from a certain installer, it won’t be featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Watertown, WI Window Replacement FAQs
What is the typical cost to install windows?
The average cost of installing a window ranges between $450 and $650. There are many factors that influence how much it costs, including how energy-efficient the windows are, local labor costs, styles and sizes of windows, the materials used in designing the windows, the number of windows and your property’s location.
What are the most common types of replacement windows?
There are several different kinds of windows you can get for your home, such as transom windows, casement windows, awning windows, picture windows, bay windows, double-hung and single-hung windows and slider windows.
What services do window replacement companies offer?
Window installation companies will do the entire process — from replacing your old windows with new ones to cleaning up after the installation. In addition, many companies offer window manufacturing, customization and repairs.
Should I replace my windows all at once?
If you’re upgrading your windows to save on your energy bills, replacing all the windows at once is the only way to gain that benefit. On the other hand, if you have just a few windows that are broken or leaky, you can replace just those.
