How Installing Energy-Efficient Windows in Nashua Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to think about making the switch:

• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
• Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
• Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower 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 in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.

Estimated Cost of Window Replacement in Nashua

Let's go over the cost of updating your windows and the types of services you may need for your home.

How Much Do New Windows Cost?

Even though the average of replacing a single window is around $600, it can range anywhere from $200 to $1,200. Costs will differ significantly depending on the quality of your products, your location, the number of windows you need and the current condition of your home. Many window companies also offer door installations and other add-ons like baths, shutters, coating and more. These extra services will increase overall project costs.

Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $463 a year on your energy bills in Nashua.

Asking for free quotes from several providers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

Generally, 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 a different style for your windows or when it has significant rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation involves replacing a window within the existing frame. So, instead of taking out the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Nashua, the choice will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Nashua

In our search to find the most reliable, eco-friendly window installers in Nashua, the EcoWatch Reviews team evaluated dozens of companies before settling on these. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:

Service Area

Since this is a guide for Nashua, we only included 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 Nashua.

Work Quality

We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each company on this list to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don't have positive things to say about their experience with a certain window installation company, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installers won't always provide the most quality service. Still, we want to make sure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.

Warranty

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

Years of Experience

Due to Nashua's climate, homeowners will want to mitigate 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.
