How Installing Energy-Efficient Windows in Woodstock Saves You Money
There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- More efficient energy use in your household: In Woodstock where the winters can be very cold, energy-efficient windows decrease the amount of heat that is lost through your windows, making it easier to keep your home warm.
- Save money on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty.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 Woodstock
Each window installation company offers varying services and has different prices based on a few factors.
How Much Do New Windows Cost?
On average, Woodstock homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost you is based on several factors, like type, size, number of windows, the location of your home, material and more.
Whether or not you want to install energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $457 a year on your energy bills in Woodstock.
The cost of your window installation will also vary based on the type of window material you choose for the frames. Wood windows are typically the most expensive, although it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat 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 offer: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails installing a new window without replacing the frame. This means instead of removing the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installer should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Woodstock
EcoWatch reviews are different from most reviews because we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them based on the following methodology:
Service Area
Because this is a guide for Woodstock, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Woodstock.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each company featured on this list to make sure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have good feedback about their experience with a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies may not provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a 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 offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Woodstock's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Woodstock window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Woodstock, CT Window Replacement FAQs
How much should window installation cost?
The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, depending on several factors. The price is generally influenced by the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which type of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — 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 handiness. Using a window replacement company can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
How long does window installation take?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
