How Installing Energy-Efficient Windows in Willimantic Saves You Money

By switching to energy-efficient windows, you can benefit in several ways, including:

• Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can reduce your carbon footprint by about 12%, according to Energy Star.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
• Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help decrease that number, which helps you save $457 a year on your bills.

Estimated Cost of Window Replacement in Willimantic

Each window replacement company offers varying services and has varying price points based on a few factors.

How Much Do New Windows Cost?

Typically, Willimantic homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at approximately $600. How much it will cost varies depending on several factors, including the location of your home, material, size, type, number of windows and more.

Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

Costs will also vary depending on the material you choose for your window frames. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

In general, there are two types of window installation services you can get: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has a lot of rot. With this service, your installers will replace the complete window, including the trim, frame and sill. A pocket installation means replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.

If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In Willimantic, the decision will mostly be influenced by the efficiency of your home and how old your existing frames are.
