Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

The EcoWatch team is all about finding solutions for eco-conscious homeowners in Dover. If your house has traditional, outdated windows, your AC or heating system could be working extra hard to heat or cool your house. This means spending more on energy bills.

That's also bad news for the environment, as the additional energy used by drafty windows increases your carbon footprint.

Efficient windows are particularly important in Dover, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $437 a year.

How Installing Energy-Efficient Windows in Dover Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could benefit you:

  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Dover, that's about 139 pounds per year on average.
  • Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
  • Save on electricity bills: Once you upgrade to 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 home.

Estimated Cost of Window Replacement in Dover

Let's go over the cost of installing new windows and the types of services you may need for your home.

How Much Do New Windows Cost?

Although the national average to replace one window is around $600, it can range anywhere from $200 to $1,200. Costs will differ significantly depending on the quality of your products, the number of windows you need, your location and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. Additional services will increase overall project costs.

Bear in mind that energy-efficient windows may have a higher price, 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 installing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Something else that affects the total cost is the material of the frame you pick. Aluminum frames are typically the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

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

Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your installers will replace the entire window, including the sill, frame and trim. A pocket installation entails installing a new window within the existing frame. This means instead of tearing out the whole window and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installer should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Dover

In our hunt to find the most reliable, eco-friendly window installers in Dover, EcoWatch evaluated dozens of companies before settling on these. We've evaluated the best window installers in Dover mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Dover, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Dover.

Work Quality

When it comes to new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good feedback about their experience with a certain installer, 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

As discussed previously, windows are a significant investment, so you'll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Dover, MA Window Replacement FAQs

How much does window installation cost?

The average cost of installing one window can range between $450 and $650. There are several factors that influence how much it costs, including local labor costs, how energy-efficient the windows are, your property's location, the number of windows, styles and sizes of windows and the materials used in designing the windows.

What type of window is the most energy-efficient?

A window's energy efficiency depends on a variety of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

Can I install my own windows?

If you're handy and have the time and patience to do the job right, you may be able to install your own windows. But if you don't have the time or know-how, we don't recommend trying it.

How long does it generally take to install windows?

Each window takes around 30 minutes to install based on the type of window. However, the window installation can take two days or more if you have a lot of windows that have to be installed.

What time of year should I replace my windows?

Replacement windows can be installed during any season, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the house, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
