How Installing Energy-Efficient Windows in Dover Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to make the switch:

• Save on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Dover, that's about 152 pounds per year on average.
• 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.

Estimated Cost of Window Replacement in Dover

When researching window installation, each company offers varying services and prices. Let's 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 installation costs can range from $200 to $1,200 per window. But costs will vary considerably depending on your location, the quality of your products, the current condition of your home and the number of windows you need. Many window companies also offer door installations and other add-ons like shutters, baths, coating and more. Additional services will increase your overall project costs.

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

We recommend requesting free quotes from multiple window installers to find the one that works best for your budget.

What Services do Window Installers Offer?

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

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 extra materials, such as insulation and drip edges, which increase the total cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails installing a new window within the existing frame. This means instead of taking out the whole unit and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're still debating which type of installation you should get, you can talk to your provider and get their recommendation. The decision mostly is influenced by the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Dover

EcoWatch is different from most reviewers since we're examining these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve the Dover area so you can find the best window installation company near you.

Work Quality

When picking new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand 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 very important review factor. If the majority of customers don't have positive feedback about their service from a certain company, it won't be featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. That's why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Dover's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Dover window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
