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 energy bills. Here are more ways switching out your windows could help you:

  • More efficient energy usage in your household: In Nashua where the winters can get cold, energy-efficient windows cut back on the amount of heat that is lost through your windows, making it easier to keep your house warm.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of household energy use. Switching to energy-efficient windows can help reduce that number, which helps you save more on your bills.

Estimated Cost of Window Replacement in Nashua

Windows come in all shapes and sizes, so costs and services will differ tremendously. Here are the average costs and the primary services that you'll find from window installation companies.

How Much Do New Windows Cost?

Generally, Nashua homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at about $600. How much it will cost is based on several factors, including the location of your home, material, number of windows, type, size and more.

It's important to keep in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Nashua homeowners $463+ a year when replacing single-pane windows.

Something else that affects the total cost is the material of the frame you choose. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won't cost as much, 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 decide what's best for your needs. In Nashua, the decision will mostly be based on the age of your home and if there's any damage. Wood can decay if it's not maintained properly over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Nashua

In our hunt to find the most reliable, eco-friendly window installers in Nashua, EcoWatch examined many companies before settling on these. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Nashua so you can find a quality window installation company near you.

Work Quality

When it comes to 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 get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

This one is a give-and-take: as with most services, cheap window installation companies won't always provide the most quality service. Still, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That's why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Nashua, NH Window Replacement FAQs

How much should a window install cost?

The national average cost of installing one window is around $600 but can range from $200 to $1,200, based on a few different factors. The price is typically dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What are the most common types of replacement windows?

There are several different types of windows you can get for your house, including double-hung and single-hung windows, awning windows, casement windows, picture windows, slider windows, transom windows and bay windows.

Can you replace your own windows?

If you're handy and know how to replace a window, it's possible to install your own windows. However, if you don't have the time or skills, we don't recommend doing it on your own.

When is it time to replace your windows?

Windows usually last about 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have an expert take a look at them to determine if they need any repairs or replacements.
