How Installing Energy-Efficient Windows in Dover Saves You Money

There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:

  • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save on energy bills: Once you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.

Estimated Cost of Window Replacement in Dover

Let’s take a look at the cost of installing new windows and the types of services you may need for your home.

How Much Do New Windows Cost?

Generally, homeowners in Dover can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. This is because window installations depend on several factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.

Bear 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 installing single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

When it comes to window installations, there are generally two kinds that your installer will have: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which raise the total cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves installing a new window without replacing the frame. This means instead of taking out the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company should be able to help you understand what’s best for your needs. In Dover, the decision will mostly depend on how old your home is and if there’s any damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Dover

EcoWatch is different from most reviewers since we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

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

Customer Reviews

Customer feedback is another super important review factor. If most customers don’t have positive things to say about their service from a certain window installation company, it won’t be featured on EcoWatch.

Cost

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

Warranty

As discussed previously, windows are a substantial investment, so you’ll want to be certain that investment is well protected. Window installation companies with 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 proven track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Dover, NJ Window Replacement FAQs

How much does window installation cost?

The national average cost of replacing one window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is often dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

What are the most common types of replacement windows?

There are several different kinds of windows you can get for your home, such as picture windows, casement windows, awning windows, slider windows, bay windows, transom windows and double-hung and single-hung windows.

Do I really need to use a window installation company?

Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional. 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 do it yourself to save money, hiring a professional is a faster, more efficient and much safer option.

Should I replace my windows all at the same time?

If you’re upgrading your windows because of energy-efficiency, replacing all of the windows at the same time is the only way to see a noticeable difference. However, if you have only a few windows that are damaged or leaky, you can replace just those.
