How Installing Energy-Efficient Windows in New Milford Saves You Money
When you switch to energy-efficient windows, you may see several perks, such as:
- Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of household energy use. Upgrading to energy-efficient windows can help reduce that amount, which helps you save $486 a year on your bills.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in New Milford
When researching window installation, each company offers different services and prices. Let's look at some typical costs and services.
How Much Do New Windows Cost?
Generally, New Milford homeowners can anticipate their window installations to range from $250 to $1,200. The average cost sits at around $600. But costs differ remarkably depending 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 add extra costs to your project.
It's also worth noting that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading the windows on your New Milford home can mean 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 varies based on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are 100% 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?
The first question to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. A pocket installation involves replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.
If you're unsure which type of window installation service you should get, your installer should be able to advise you. Typically, the decision is influenced by 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 New Milford
EcoWatch differs from other reviewers because we examine these companies through a sustainability lens. We've reviewed the top window replacement companies in New Milford mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the New Milford area so you can find a quality window installation company near you.
Work Quality
When installing 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 opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the highest rates of 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 parts, quality of installation, professionalism, cost, warranty and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when 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. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of New Milford's climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of New Milford window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
New Milford, CT Window Replacement FAQs
How much does a window install cost?
The typical cost to install a window ranges from $450 to $650. There are many factors that influence how much it costs, such as the number of windows, styles and sizes of windows, your property's location, local labor costs, how energy-efficient the windows are and the materials used in designing the windows.
What are the types of windows?
The most common kinds of windows for homes include: slider windows, awning windows, casement windows, picture windows, bay windows, double-hung and single-hung windows and transom windows.
When should I use a window installation company?
Unless you have home repair skills and have the tools needed to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and much safer alternative.
How long does window installation take?
Because the average installation time is 30 minutes per window, about 16 windows can be installed in an 8-hour work day.
What time of year is a good time to replace my windows?
Although you can install windows any time of year, warmer weather is usually better for replacing windows. Additionally, it shouldn't be raining, as rain can make the installation more difficult.
