How Installing Energy-Efficient Windows in Hanover Saves You Money

By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:

• 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.
• Protect your investment: If you have a relatively old home, your windows are most likely outdated. 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: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll need less energy to heat or cool your house.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Hanover, that’s about 449 pounds per year on average.

How Much Do New Windows Cost?

Costs will vary considerably based on the current condition of your home, the quality of your products, your location and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase overall project costs.

Getting free quotes from multiple installers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this kind 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 should get.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
