How Installing Energy-Efficient Windows in Rochester Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Better temperature control in your home: Residing in a cold city like Rochester often means relying on your heater to keep your house cool. Energy-efficient windows can cut back on how hard your heating system needs to work to heat your home.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
- Save on electricity bills: After you install energy-efficient windows, you can see a reduction in your bills by about 12% because you'll need less energy to heat or cool your home.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Rochester
Let's go over the cost of updating your windows and the kinds of services you may need for your home.
How Much Do New Windows Cost?
On average, Rochester homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at around $600. This is because the cost of window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly during the winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Rochester homeowners $459+ a year after replacing single-pane windows.
How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services companies provide: full-frame and pocket installations.
A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation entails replacing a window without replacing the frame. So, instead of removing the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're unsure which type of window installation service you should get, your installer can help you out. Typically, the decision is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Rochester
EcoWatch differs from most reviewers because we examine these companies through a sustainability lens. We have reviewed the top window installation companies in Rochester mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Rochester, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Rochester.
Work Quality
When choosing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you opt for. 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 very important review factor is customer feedback. If the majority of customers don't have nice things to say about their experience with a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window companies are not going to provide the most quality service. On the other hand, 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
As discussed previously, windows are a sizable investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Rochester, NH Window Replacement FAQs
What is the average cost to install windows in a home?
The average cost of replacing a single window can range from $450 to $650. There are many factors that influence the price, which include your property's location, styles and sizes of windows, local labor costs, the materials used in designing the windows, how energy-efficient the windows are and the number of windows.
Which kind of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you'll have 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 I replace my own windows?
Although it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. 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 the best time of year to replace windows?
While you can install windows any time of year, warmer weather is often better for replacing windows. Additionally, the weather should be dry, because rain can make the installation more difficult.
