How Installing Energy-Efficient Windows in Spencer Saves You Money

By switching to energy-efficient windows, you and your family can take advantage of several benefits, including:

  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Spencer, that's about 139 pounds per year on average.
  • Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Replacing your windows with energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.

Estimated Cost of Window Replacement in Spencer

When looking into window installation, each company offers varying services and costs. Let's look at some typical costs and services.

How Much Do New Windows Cost?

Generally, Spencer homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost is at around $600. But prices vary 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 provide door installations, which will make your project cost more.

Keep 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.

We recommend requesting free quotes from multiple window companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

There are typically two types of window replacement services: full-frame and pocket installations.

Full-frame installations involve replacing the full window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has noticeable rot. Full-frame installations are more involved and will increase the overall cost. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

Your window installation company can help you choose which type of installation you should get.

How We Choose the Best Window Installers in Spencer

In our hunt to find the most reliable, eco-friendly window installers in Spencer, the EcoWatch team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed each installer and assigned rankings based on the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Spencer so you can find the right 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 company included in our guide to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including cost, quality of installation, quality of parts, professionalism, warranty and more.

Cost

This one is a give-and-take: as with most services, cheap window companies are not going to provide the most quality service. On the other hand, we want to ensure we're highlighting companies that provide a variety 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 with 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 are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Spencer, MA Window Replacement FAQs

What is the typical cost to replace windows in a home?

The national average cost of installing one window is around $600 but can range between $200 and $1,200, depending on several factors. The price is often influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

Which type of window is the best?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.

Can I replace my own windows?

Even though it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. Hiring a professional can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

What time of year is a good time to replace my windows?

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

How often do you need to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to operate, they may need to be replaced.
