Estimated Cost of Window Replacement in Westerly
When looking into window installation, each company provides varying services and prices. Let’s take a look at some typical costs and services.
How Much Do New Windows Cost?
According to our research, the national average cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. How much it will cost is based on several factors, like material, the location of your home, size, number of windows, type and more.
Whether or not you want energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $382 a year on your energy bills in Westerly.
We advise getting free quotes from several window companies to find the one that works best for you.
What Services do Window Installers Offer?
In general, there are two kinds of window installation services companies provide: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In Westerly, the decision will mostly depend on how much damage there is currently and the age of your existing frames.

Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.

Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including cost, quality of parts, quality of installation, warranty, professionalism and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies won’t always provide the most quality service. Still, 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 previously, windows are a sizable investment, so you’ll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience

Westerly, RI Window Replacement FAQs
How much should a window install cost?
The typical cost to install one window can range from $450 to $650. There are many factors that affect the cost, such as local labor costs, the number of windows, how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows and your property’s location.
What type of window is the most energy-efficient?
A window’s energy efficiency is affected by a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
What services do window installation companies provide?
Window installers travel to your property to remove your old windows and replace them with new ones. Some providers install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation is done.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, you probably need to replace all of them. At that point, they are usually less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
How long does it generally take to install windows?
Each window takes around 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
