How Installing Energy-Efficient Windows in Charlestown Saves You Money

There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the switch are the following:

  • 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 Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Charlestown, that's about 131 pounds per year on average.
  • Save money on power bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save around $422 annually on your energy bills in Charlestown.

Estimated Cost of Window Replacement in Charlestown

Windows come in varying purposes, styles and shapes, so costs and services will vary considerably depending on your project. Below, we detail the typical cost and services that you'll find from window replacement companies.

How Much Do New Windows Cost?

According to our research, the average cost to install a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. But costs will differ considerably based on the number of windows you need, the current condition of your home, your location and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase overall project costs.

It's important to bear in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Charlestown homeowners $422+ a year when replacing single-pane windows.

Something else that influences the total cost is the material of the frame you select. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they provide 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 and cost somewhere between the other two.

What Services do Window Installers Offer?

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

A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.

Your window installer can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Charlestown

In our hunt to make your home improvements easier and more eco-friendly in Charlestown, the EcoWatch Reviews team evaluated many companies before deciding on these. Along with energy efficiency, we reviewed each installer and assigned rankings using the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve Charlestown 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

Customer feedback is another very important review factor. If the majority of customers don't have positive feedback about their experience with a certain window installation company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window companies won't always provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a hefty investment, so you'll want to be certain that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Charlestown, RI Window Replacement FAQs

How much should window installation cost?

The national average cost to replace one window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically 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 initially but can save you a decent amount of money a year in energy bills.

What kind of window is the best for energy efficiency?

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

Do you really have to use a window installation company?

Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer alternative.

How long does window installation generally take?

Because the average installation time is 30 minutes per window, around 16 windows can be installed during a typical 8-hour work day.

Should I replace my windows all at the same time?

If you're upgrading your windows to save on your energy bills, replacing all the windows together is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are damaged or leaky, you can replace just those.
