How Installing Energy-Efficient Windows in Gloucester Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here's more information on how upgrading your windows could benefit you:

• Reduce your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
• Save on power bills: Installing energy-efficient windows reduces your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in Gloucester

Windows come in different shapes and sizes, so costs and services will differ greatly. Here are the typical costs and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Although the national average cost of replacing one window is around $600, it can range anywhere from $200 to $1,200. Costs will vary significantly depending on your location, the current condition of your home, the quality of your products and the number of windows you need. Many window companies also offer door installations and other add-ons like baths, coating, shutters and more. These extra services will increase your overall project costs.

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

The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

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

A full-frame installation is a replacement of the full window. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which increase the total cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you’re still trying to decide which kind of installation you need, you can consult with your provider and get their recommendation. The choice mostly depends on the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Gloucester

The EcoWatch Reviews team differs from most reviewers, as we evaluate these companies through a sustainability lens. We’ve assessed the top window installers in Gloucester mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Because this is a guide for Gloucester, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Gloucester.

Work Quality

When installing new windows, the quality and breadth 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 super important review factor. If most customers don’t have positive things to say about their experience with a certain installer, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installation companies are not going to provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a sizable investment, so you’ll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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