How Installing Energy-Efficient Windows in Fitchburg Saves You Money

By upgrading to energy-efficient windows, you can enjoy several benefits, such as:

  • Save on electricity bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save about $482 annually on your energy bills in Fitchburg.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Fitchburg, that’s about 139 pounds per year on average.

Estimated Cost of Window Replacement in Fitchburg

Each window replacement company offers varying services and has different costs based on a few factors.

How Much Do New Windows Cost?

Typically, Fitchburg homeowners can expect their window installations to range from $250 to $1,200. The average cost sits at approximately $600. But costs will vary significantly depending on your location, the quality of your products, the number of windows you need and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.

It’s important to remember that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Fitchburg homeowners $482+ a year when replacing single-pane windows.

Something else that affects the overall cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

When considering window replacements, there are typically two kinds that your provider will have: full-frame and pocket installations.

Full-frame installations entail replacing the complete window, including the frame, trim and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable damage or rot. These installations are more involved and will increase the total cost. 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 kind of installment if you have any pre-existing rot or water damage.

Your window installer can help you choose which type of installation you need.

How We Choose the Best Window Installers in Fitchburg

The EcoWatch Reviews team differs from other reviewers because we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

When selecting new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have good feedback about their experience with a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as 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 to many homeowners. That’s why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Fitchburg’s climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Fitchburg window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Fitchburg, MA Window Replacement FAQs

What is the average cost to install windows?

The national average cost of replacing a single window is about $600 but can range from $200 to $1,200, based on several factors. The price is often dependent on the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What kind of window is the most energy-efficient?

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

What services do window replacement companies do?

Window installers visit your house to remove your old windows and replace them with new ones. Some companies install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

Should I replace my windows all at the same time?

If your windows are more than 20 years old, it’s most likely time to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
