How Installing Energy-Efficient Windows in New Milford Saves You Money

By switching to energy-efficient windows, you and your family can benefit in several ways, such as:

• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In New Milford, that’s about 147 pounds per year on average.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Save money on power bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll require less energy to heat or cool your home.
• 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 increase the value of your house if you decide to sell.

Estimated Cost of Window Replacement in New Milford

Let’s go over the cost of window replacement and the kinds of services offered by installers.

How Much Do New Windows Cost?

The typical cost to replace a single window is about $600 but can range from $200 to $1,200. Costs will vary considerably depending on the number of windows you need, the quality of your products, the current condition of your home and your location. A lot of window companies also offer door installations and other add-ons like baths, shutters, coating and more. These extra services will increase overall project costs.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save New Milford homeowners $486+ a year after replacing single-pane windows.

The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are solid 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 step of a window installation is to figure out whether you should get a full-frame or pocket installation.

Full-frame installations are necessary when you want a new style or your window has a lot of deterioration. With this service, your installers will replace the total window, including the trim, sill and frame. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re unsure which kind of window installation service you need, your installer should be able to help you out. Generally, the choice is based on 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 New Milford

EcoWatch reviews are different from other reviews because we look at these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in New Milford and assigned rankings using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the New Milford area so you can find the best window installation company near you.

Work Quality

When picking new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window 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

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have good things to say about their experience with a certain company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installers won’t always provide the highest quality service. On the other hand, we want to ensure 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 to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to New Milford’s climate, homeowners need to be wary of water damage, low efficiency 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.
