How Installing Energy-Efficient Windows in Southborough Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to take the plunge and make the switch:

• Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
• Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 139 pounds.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help lower that amount, which helps you save $482 a year on your bills.

Estimated Cost of Window Replacement in Southborough

Windows come in varying purposes, styles and shapes, so costs and services will vary tremendously based on your project. Below, we describe the typical cost and services that you can get from window installers.

How Much Do New Windows Cost?

Although the national average cost to install a single window is about $600, it can range anywhere from $200 to $1,200. How much it will cost is based on several factors, like the location of your home, type, size, number of windows, material and more.

It’s also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that upgrading the windows on your Southborough home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

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

A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which raise the overall cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re still debating which kind of installation to get, you can talk to your provider and get their advice. The choice mostly depends on how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Southborough

EcoWatch differs from most reviewers since we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:

Service Area

Since this is a guide for Southborough, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Southborough.

Work Quality

When selecting new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. 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

Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have positive things to say about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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