How Installing Energy-Efficient Windows in Hanover Saves You Money

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

• Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
• Save money on power bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 152 pounds.

Estimated Cost of Window Replacement in Hanover

When considering window installation, each company offers different services and prices. Let's take a look at some typical costs and services.

How Much Do New Windows Cost?

According to our research, the typical cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. But prices differ remarkably 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 provide door replacements, which will add extra costs to your project.

Bear in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are usually the most expensive, but it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

Full-frame installations entail replacing the complete window, including the frame, trim and sill. You most likely need a full-frame installation when you want a new style or your window has significant rot. Because full-frame installations are more involved, they will raise overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the 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.

If you're not sure which type of window installation service you need, your installer should be able to assist you. In general, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Hanover

EcoWatch is different from most reviewers because we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings based on the following methodology:

Service Area

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

Work Quality

When installing new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand 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 super important review factor is customer feedback. If the majority of customers don't have good feedback about their service from a certain installer, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installers won't always provide the highest quality service. On the other hand, 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. That's why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
