How Installing Energy-Efficient Windows in Terryville Saves You Money
By switching to energy-efficient windows, you can enjoy several benefits, such as:
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 147 pounds.
- Save money on energy bills: Since energy-efficient windows decrease the amount of energy used to heat or cool your home, the switch can help you save around $437 annually on your energy bills in Terryville.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Terryville
Windows come in different shapes and sizes, so costs and services will vary tremendously. Here are the typical costs and the primary services that you'll find from the average window installation company.
How Much Do New Windows Cost?
On average, Terryville homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost is at around $600. But prices vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which will make your project cost more.
It's also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star estimates that switching out the windows on your Terryville home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Another factor that affects the total cost is the material you select for your frame. Aluminum frames are usually the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
When it comes to window replacements, in general there are two kinds that your installer will offer: full-frame and pocket installations.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
If you're not sure which window installation service you need, your installer should be able to assist you. Typically, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Terryville
In our hunt to find the most reliable, eco-friendly window installers in Terryville, the EcoWatch Reviews team evaluated many companies before landing on these. Along with energy efficiency, we evaluated window companies all across the state and ranked them using the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the Terryville area so you can find the right window installation company near you.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer in our guide to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have positive feedback about their service from a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. On the other hand, we want to ensure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a hefty investment, so you'll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Terryville, CT Window Replacement FAQs
What is the average cost to install windows in a home?
The national average cost of replacing one window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is typically dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the most common kinds of replacement windows?
The most common kinds of windows for homes include: slider windows, awning windows, transom windows, picture windows, bay windows, double-hung and single-hung windows and casement windows.
Do you really have to use a window installation company?
Unless you have experience with home improvement projects and have all the tools you need to replace your own windows, we recommend hiring a professional installer. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer alternative.
What time of year should I replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the house, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
Should I replace all my windows at the same time?
If your windows are more than 20 years old, it's probably time to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
