How Installing Energy-Efficient Windows in Wilton Saves You Money

By switching to energy-efficient windows, you can enjoy several benefits, including:

  • Save on power bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your house.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Better temperature control in your home: Residing in a cold city like Wilton usually means relying on your heater to keep your house cool. Energy-efficient windows can cut back on how hard your heating system needs to work to heat your home.

Estimated Cost of Window Replacement in Wilton

Each window replacement company provides varying services and has varying costs depending on a few factors.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. But prices differ 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 offer door installations, which will make your project cost more.

Keep in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

We advise getting free quotes from several window companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services you can get: full-frame and pocket installations.

Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your installers will replace the complete window, including the sill, trim and frame. A pocket installation involves installing a new window within the frame that's already there. This means instead of tearing out the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're not sure which window installation service you should get, your installer should be able to advise you. Typically, the choice is influenced by 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 Wilton

EcoWatch reviews differ from most reviews because we're examining these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:

Service Area

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

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer included in our guide to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of parts, professionalism, quality of installation, cost, warranty and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important. That's why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Wilton, NH Window Replacement FAQs

How much does a window install cost?

The typical cost to install one window ranges between $450 and $650. There are a variety of factors that affect how much it costs, such as the number of windows, local labor costs, your property's location, styles and sizes of windows, how energy-efficient the windows are and the materials used in designing the windows.

Which kind of window should I get?

A window's energy efficiency depends on a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.

Can you replace your own windows?

Although it is possible to install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help ensure that the job is done properly and that you won't have to spend the time and effort to do it yourself.

What time of year should I replace my windows?

Even though you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, it shouldn't be raining, since rain can make the installation harder.
