How Installing Energy-Efficient Windows in Hanover Saves You Money

There are quite a few benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:

  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Hanover, that’s about 152 pounds per year on average.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
  • Protect your investment: If you have an older home, 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.
  • Save money on electricity bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $560 annually on your energy bills in Hanover.

Estimated Cost of Window Replacement in Hanover

Each window installation company provides various services and has different costs based on a few factors.

How Much Do New Windows Cost?

Though the average cost to replace one window is about $600, it can range anywhere from $200 to $1,200. But prices differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will make your project cost more.

With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Hanover homeowners $560+ a year after replacing single-pane windows.

We advise requesting free quotes from several window companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

There are typically two kinds of window installation services: full-frame and pocket installations.

A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

Your window installation company can help you decide which type of installation you need.

How We Choose the Best Window Installers in Hanover

In our search to find the most reliable, eco-friendly window installers in Hanover, EcoWatch landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.

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 type of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

This one is a give-and-take: as with other services, cheap window companies may not provide the highest quality service. On the other hand, we want to make sure 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. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Hanover, NH Window Replacement FAQs

What is the typical cost to install windows in a home?

The typical cost to install one window can range from $450 to $650. There are several factors that affect the price, including the number of windows, how energy-efficient the windows are, your property’s location, the materials used in designing the windows, styles and sizes of windows and local labor costs.

What are the different kinds of windows?

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

Can I install my own windows?

If you’re handy and have the time and patience to do the job right, you may be able to install your own windows. However, if you don’t have the time or experience, we don’t recommend doing it on your own.

When is the best time of year to replace windows?

Though you can install windows any time of year, warmer weather is typically better for installing replacement windows. In addition, it shouldn’t be raining, as rain can make the installation more difficult.
