How Installing Energy-Efficient Windows in Bethel Saves You Money
When you switch to energy-efficient windows, you may see several benefits, such as:
- Protect your investment: Upgrading 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 from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Installing energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: In Bethel, you can reduce your indirect greenhouse gas emissions by about 147 pounds per year once you upgrade to energy-efficient windows.
Estimated Cost of Window Replacement in Bethel
Let's go over the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Though the typical of installing a single window is around $600, it can range from $200 to $1,200. But costs vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which will make your project cost more.
It's also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that upgrading the windows on your Bethel 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 upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
There are typically two types of window installation services: full-frame and pocket installations.
Full-frame installations entail replacing the total window, including the sill, trim and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable rot. Full-frame installations are more involved and will increase the overall cost. A pocket installation involves replacing a window without replacing the frame. This means instead of taking out the whole window and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installer should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Bethel
In our hunt to find the most reliable, eco-friendly window installers in Bethel, the EcoWatch Reviews team assessed many companies before settling on these. Along with energy efficiency, we evaluated window companies all across the state and ranked them using the following methodology:
Service Area
Since this is a guide for Bethel, we gave more points to companies that serve the city. There are other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Bethel.
Work Quality
When choosing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends 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, professionalism, quality of parts and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. 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 installers 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.
Bethel, CT Window Replacement FAQs
What is the typical cost to install new windows in a home?
The typical cost to install a window ranges between $450 and $650. There are a variety of factors that influence how much it costs, which include the materials used in designing the windows, local labor costs, styles and sizes of windows, the number of windows, your property's location and how energy-efficient the windows are.
What are the most common kinds of replacement windows?
The most common types of windows for homes are transom windows, casement windows, awning windows, picture windows, bay windows, slider windows and double-hung and single-hung windows.
When do I have to use a window installation company?
Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional. The process of installing windows is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer alternative.
How often do you need to replace windows?
Windows usually have a lifespan of 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have them checked by an expert to determine if they are in need of a repair or replacement.
Should I replace all my windows at once?
If you're upgrading your windows to save on your energy bills, replacing all your windows together is the only way to see a noticeable difference. On the other hand, if you have only a few windows that are broken or drafty, you can replace just those.
