How Installing Energy-Efficient Windows in Northampton Saves You Money

Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to take the plunge and make the switch:

• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
• Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
• Save on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.

Estimated Cost of Window Replacement in Northampton

Let’s take a look at the cost of window installation and the types of services offered by installers.

How Much Do New Windows Cost?

Generally, homeowners in Northampton can expect that most window installations will range from $250 to $1,200, with the average cost at about $600. How much it will cost varies based on several factors, like number of windows, the location of your home, material, type, size 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 installing single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using 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 offer decent insulation for your home.

What Services do Window Installers Offer?

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

Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. With this service, your installers will replace the entire window, including the frame, trim and sill. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

Your window installation company will be able to help you choose what’s best for your needs. In Northampton, the decision will mostly be based on how old your windows are and if there’s any moisture damage. Wood can decay if it’s not maintained properly over the years, so it’s good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Northampton

EcoWatch reviews differ from other reviews, as we examine these companies through a sustainability lens. We have assessed the top window replacement companies in Northampton mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Northampton, we gave more points to companies that cover the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Northampton.

Work Quality

When picking new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand of window you choose. 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 very important review factor is customer feedback. If the majority of customers don’t have positive feedback about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as 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 considerable investment, so you’ll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
