How Installing Energy-Efficient Windows in Williamstown Saves You Money

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

• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
• Reduce your carbon footprint: In Williamstown, you can reduce your indirect greenhouse gas emissions by about 206 pounds per year when you upgrade to energy-efficient windows.
• Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower that number, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Williamstown

Windows come in varying purposes, shapes and styles, so costs and services will differ tremendously depending on your project. Below, we describe the typical cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range from $200 to $1,200. Costs will differ considerably depending on the number of windows you need, the quality of your products, your location and the current condition of your home. A lot of window companies also offer door installations and other add-ons like baths, coating, shutters and more. Additional services will increase your overall project costs.

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

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

What Services do Window Installers Offer?

In general, there are two types of window replacement services companies provide: full-frame and pocket installations.

A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you're unsure which type of window installation service you should get, your installer can assist you. Generally, the choice is based 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 Williamstown

EcoWatch reviews are different from other reviews, as we examine these companies through a sustainability lens. We have assessed the best window installation companies in Williamstown mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

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

Work Quality

When picking new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand 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 positive things to say about their service from a certain window installation company, it won't be featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

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

Years of Experience

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