How Installing Energy-Efficient Windows in Mantua Saves You Money

There are several benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Decrease your carbon footprint: By using less energy after you upgrade to Energy Star certified windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
• Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that number, which helps you save some money on your bills.

Estimated Cost of Window Replacement in Mantua

Let’s go over the cost of replacing your windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

According to our research, the typical cost to replace a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. How much it will cost depends on several factors, including size, number of windows, material, type, the location of your home and more.

Keep in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

When considering window installations, there are typically two kinds that your installer will offer: full-frame and pocket installations.

Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot. With this service, your installers will replace the full window, including the sill, trim and frame. A pocket installation entails installing a new window without replacing the frame. This means instead of tearing out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re not sure which window installation service you should get, your installer can help you out. Typically, the decision depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Mantua

EcoWatch reviews are different from other reviews, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Mantua and assigned rankings based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve Mantua so you can find the right window installation company near you.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company on this list to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have good things to say about their experience with a certain window installation company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies won’t always provide the most quality service. Still, we want to make sure we’re highlighting companies that provide 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 give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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