How Installing Energy-Efficient Windows in Dover Saves You Money

When you upgrade to energy-efficient windows, you may see several perks, including:

  • Save on energy bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll require less energy to heat or cool your home.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
  • Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 206 pounds per year on average.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.

Estimated Cost of Window Replacement in Dover

Each window replacement company offers varying services and has varying costs depending on several factors.

How Much Do New Windows Cost?

Generally, homeowners in Dover can expect that most window installations will cost between $250 and $1,200, with the average cost at about $600. This is due to the fact that the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.

It's important to bear in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Dover homeowners $270+ a year when replacing single-pane windows.

We recommend getting free quotes from multiple window installers to find the one that works best for you.

What Services do Window Installers Offer?

In general, there are two kinds of window installation services you can get: full-frame and pocket installations.

A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. A pocket installation entails replacing a window within the existing frame, which is generally cheaper than a full-frame installation.

If you're still debating which type of installation you should get, you can consult with your installer and get their advice. The choice mostly depends on how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Dover

In our search to find the most reliable, eco-friendly window installers in Dover, EcoWatch assessed many companies before deciding on these. We've evaluated the best window replacement companies in Dover mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Dover, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Dover.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each installer in our guide to make sure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, warranty, quality of installation, cost, professionalism and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies may not provide the most quality service. Still, we want to ensure 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. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Dover, NJ Window Replacement FAQs

How much should a window install cost?

The national average cost to install one window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is typically dependent on the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

Which type of window should I get?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.

Do I really have to use a window installation company?

Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring a professional installer. The window installation process is complex and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer alternative.

How long does it generally take to install windows?

Because the average installation time of a window is 30 minutes, around 16 windows can be installed in an 8-hour work day.

When is the best time of year to replace windows?

While you can install windows any time of year, warmer weather is usually better for replacing windows. In addition, it shouldn't be raining, as rain can make the installation harder.
