How Installing Energy-Efficient Windows in Hanover Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways upgrading your windows could benefit you:

  • Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 152 pounds.
  • 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 because of their ability to filter out harmful UV rays.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
  • Save on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in Hanover

Each window installation company provides varying services and has varying prices based on several factors.

How Much Do New Windows Cost?

According to our market research, the average cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. How much it will cost varies based on several factors, like the location of your home, type, number of windows, material, size and more.

Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $560 a year on your energy bills in Hanover.

Another factor that influences the total cost is the material of the frame you pick. Aluminum frames are typically the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when planning a window replacement is to think about whether you want a full-frame or pocket installation.

A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve other materials, including insulation and drip edges, which raise the total 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 are simpler and won’t cost as much, as they involve simply replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

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

How We Choose the Best Window Installers in Hanover

In our hunt to make your home improvements easier and more eco-friendly in Hanover, the EcoWatch team evaluated many companies before landing on these. We’ve decided to review the best window replacement companies in Hanover mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

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 these issues. If a company has less than 10 years of experience, it loses points in this category.

Hanover, NH Window Replacement FAQs

What is the average cost to install windows?

The average cost to install one window ranges between $450 and $650. There are a variety of factors that affect the cost, which include how energy-efficient the windows are, your property’s location, the materials used in designing the windows, local labor costs, styles and sizes of windows and the number of windows.

What are the different kinds of windows?

The most common kinds of windows for homes include: transom windows, awning windows, double-hung and single-hung windows, casement windows, bay windows, picture windows and slider windows.

Can you replace your own windows?

If you’re handy and have experience with similar home improvement projects, you may be able to install your own windows. But 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?

Even though you can install windows any time of year, warmer weather is often better for installing replacement windows. Additionally, it shouldn’t be raining, because rain can make the installation more difficult.

How often do you need to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
