How Installing Energy-Efficient Windows in Hanover Saves You Money
There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Reduce your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if you have an older home.
Estimated Cost of Window Replacement in Hanover
Each window installation company provides various services and has varying prices depending on several factors.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range from $200 to $1,200. These figures vary based on specific characteristics of your installation, like number of windows, the location of your home, type, size, material and more.
It’s important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Hanover homeowners $315+ a year when replacing single-pane windows.
Another factor that influences the overall cost is the material you choose for your frame. Aluminum frames are generally the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
When considering window replacements, in general there are two types that your installer will have: full-frame and pocket installations.
A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. Because this type of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installation company can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Hanover
In our search to make your home improvements easier and more eco-friendly in Hanover, the EcoWatch Reviews team examined dozens of companies before deciding on these. We’ve reviewed the top window replacement companies in Hanover primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Hanover so you can find a quality window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don’t have good 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: as with most services, cheap window companies may not provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a range 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 provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Hanover’s climate, homeowners need to be wary of rot, low efficiency and water damage. 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.
