How Installing Energy-Efficient Windows in Vernon Saves You Money
There are quite a few perks of switching to energy-efficient windows. A few reasons you may want to consider making the switch are the following:
- Save on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
- Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Vernon, that’s about 147 pounds per year on average.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Vernon
Let’s take a look at the cost of window replacement and the types of services you may need for your home.
How Much Do New Windows Cost?
According to our research, the typical cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. This is because window installations are based on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Vernon homeowners $461+ a year after replacing single-pane windows.
How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are usually the most expensive, although it depends on whether they are solid 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?
There are generally two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations entail replacing the complete window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant rot or deterioration. These installations are more involved and will raise overall costs. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you’re unsure which window installation service you should get, your installer can advise you. In general, 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 Vernon
In our search to find the most reliable, eco-friendly window installers in Vernon, EcoWatch chose the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed each installer and ranked them using the following methodology:
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 the right window installation company near you.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company included on this list to ensure its contractors are well-qualified and that the company has received plenty 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, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including quality of parts, quality of installation, professionalism, cost, warranty and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Vernon’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Vernon window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Vernon, CT Window Replacement FAQs
How much should window installation cost?
The national average cost to replace a single window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is usually dependent on the type and material of the window, the location of your property and the size 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.
Which type of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. To be sure you’re getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.
What do window installers do?
Window installers visit your property to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.
What time of year is the best time to replace my windows?
Although you can install windows any time of year, warmer weather is generally better for replacing windows. Additionally, it shouldn’t be raining, because rain can make the installation more difficult.
