How Installing Energy-Efficient Windows in Dover Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could help you:

• Save money on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% since you need less energy.
• Protect your investment: If you have a relatively old home, your windows are most likely outdated.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 raise the value of your property if you decide to sell.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Better temperature control in your home: Energy-efficient windows can cut back on how much heat is lost through your windows when heating your home.

Estimated Cost of Window Replacement in Dover

Each window installation company offers various services and has varying costs depending on a few factors.

How Much Do New Windows Cost?

On average, Dover homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at about $600. But costs vary considerably based 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 installations, which will add extra costs to your project.

It's important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Dover homeowners $459+ a year when replacing single-pane windows.

How much your window installation costs will also vary based on the type of material you choose for the frames. Wood windows are generally the most expensive, although it depends if they are completely 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?

The first thing to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company can help you choose which type of installation you need.

How We Choose the Best Window Installers in Dover

In our hunt to find the most reliable, eco-friendly window installers in Dover, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. We have evaluated the best window installation companies in Dover mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

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 choosing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including professionalism, cost, quality of parts, quality of installation, warranty and more.

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 awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

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

Years of Experience

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