How Installing Energy-Efficient Windows in Oxford Saves You Money
When you switch to energy-efficient windows, you may see several perks, including:
- Reduce your carbon footprint: By using less energy after you switch to Energy Star certified windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that number, which helps you save $420 a year on your bills.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Oxford
Each window installer provides varying services and has varying price points depending on several factors.
How Much Do New Windows Cost?
According to our research, the national average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. These estimates vary depending on the specifics of your installation, like material, the location of your home, type, size, number of windows and more.
With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Oxford homeowners $420+ per year after replacing single-pane windows.
Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also provide 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?
In regard to window installations, in general there are two kinds that your installer will have: full-frame and pocket installations.
Full-frame installations involve replacing the full window, including the frame, trim and sill. You most likely need a full-frame installation when you want a new style or your window has significant damage or rot. Because these installations are more involved, they will increase the overall cost. Pocket installations are on the simpler end and won’t carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.
If you’re still trying to decide which type of installation to get, you can ask your installer and get their recommendation. The decision mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Oxford
The EcoWatch Reviews team differs from most reviewers, as we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:
Service Area
This one is 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
When it comes to new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, cost, warranty, quality of parts, professionalism and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies may not provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a wide 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 with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Oxford, CT Window Replacement FAQs
How much should a window install cost?
The average cost of installing one window ranges between $450 and $650. There are many factors that affect the cost, which include how energy-efficient the windows are, local labor costs, styles and sizes of windows, the number of windows, your property’s location and the materials used in designing the windows.
What are the most common kinds of replacement windows?
There are various kinds of windows you can get for your home, such as awning windows, slider windows, transom windows, bay windows, double-hung and single-hung windows, picture windows and casement windows.
What do window installers do?
Window installers go 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.
What time of year is the best time to replace my windows?
Even though you can install windows any time of year, warmer weather is generally better for replacing windows. In addition, the weather should be dry, because rain can make the installation more difficult.
How long does it take to install windows?
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 have a lot of windows that need to be installed.
