How Installing Energy-Efficient Windows in Oxford Saves You Money
There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Save on energy bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll need less energy to heat or cool your house.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Reduce your carbon footprint: In Oxford, you can lower your indirect greenhouse gas emissions by about 147 pounds per year after you install energy-efficient windows.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged.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.
Estimated Cost of Window Replacement in Oxford
Windows come in varying shapes, styles and purposes, so costs and services will differ greatly based on your project. Below, we describe the average cost and services that you'll find from window installers.
How Much Do New Windows Cost?
Although the typical to install a single window is about $600, it can range anywhere from $200 to $1,200. This is due to the fact that window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.
It's also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star predicts that switching out the windows on your Oxford home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using 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?
There are typically two types of window installation services: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which increase the total cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.
Your window replacement company should be able to help you understand what's best for your needs. In Oxford, the decision will mostly be based on the age of your home and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Oxford
EcoWatch reviews are different from other reviews since we examine these companies through a sustainability lens. We have evaluated the best window installation companies in Oxford mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the Oxford area so you can find a quality window installation company near you.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer on this list to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including warranty, quality of parts, professionalism, cost, quality of installation and more.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the most quality service. Still, we want to ensure 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 well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Oxford, CT Window Replacement FAQs
What is the typical cost to replace windows?
The national average cost to replace one window is around $600 but can range from $200 to $1,200, based on a few different factors. The price is generally dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What kind of window is the best for energy efficiency?
Generally, double-pane windows will be 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'll get 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.
Do you really need to use a window installation company?
You should hire a window installation company whenever you want new windows. Installing windows is a complicated process that can take a lot of time, so it's best handled by the professionals.
How long does it typically take to install windows?
Each window takes around 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is generally better for installing replacement windows. Additionally, it shouldn't be raining, as rain can make the installation harder.
