How Installing Energy-Efficient Windows in Worcester Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could help you:

• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.
• Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Installing energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Worcester

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

How Much Do New Windows Cost?

According to our research, the national average cost of replacing a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. These figures vary depending on the specifics of your installation, such as type, material, size, number of windows, the location of your home and more.

Bear 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 you install single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Something else that influences the total cost is the material you choose for your frame. Aluminum frames are usually the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most 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?

The first step of a window installation is to decide whether you want a full-frame or pocket installation.

A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

If you’re not sure which window installation service you need, your installer should be able to help you out. Typically, the decision depends on 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 Worcester

The EcoWatch Reviews team differs from most reviewers since we’re examining these companies through a sustainability lens. We’ve evaluated the top window installation companies in Worcester mainly based on their energy efficient offerings, 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 takes the following factors into consideration:

Service Area

Since this is a guide for Worcester, we only included companies that provide services to the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Worcester.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer featured on this list to ensure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a substantial investment, so you’ll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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