How Installing Energy-Efficient Windows in Nashua Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how switching out your windows could help you:

• Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
• Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Nashua, that’s about 152 pounds per year on average.

Estimated Cost of Window Replacement in Nashua

Windows come in varying purposes, shapes and styles, so costs and services will differ greatly based on your project. Below, we go over the average cost and services that you can get from window installers.

How Much Do New Windows Cost?

Even though the typical cost of replacing a single window is about $600, it can range anywhere from $200 to $1,200. These estimates are based on specific characteristics of your installation, including type, material, number of windows, the location of your home, size and more.

Keep 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 a year when replacing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Something else that influences the overall cost is the material you select for your frame. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, as 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?

In regard to window replacements, there are generally two types that your provider will have: full-frame and pocket installations.

Full-frame installations involve replacing the full window, including the sill, frame and trim. 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 overall cost. A pocket installation involves installing a new window within the old frame. So, instead of removing the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company will be able to help you decide what’s best for your needs. In Nashua, the decision will mostly be based on how old your home is and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Nashua

The EcoWatch Reviews team is different from other reviewers, as we look at these companies through a sustainability lens. We’ve assessed the top window installation companies in Nashua mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

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

Work Quality

When installing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

This one is a give-and-take: similar to other services, cheap window installers won’t always provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

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