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.

A review of the top window installation companies in Dover may not seem like the most interesting article on the EcoWatch site, but trust us, windows have more of an impact on your life than you might realize. The Department of Energy estimates that heat gained or lost through old or damaged windows could be responsible for close to 30% of heating and cooling usage. In Dover, where the electricity bills are an average of $36 per month, that's almost $$130 per year wasted.

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

So if you're constructing a new home, renovating or replacing your windows in Dover, this is the best place to get started.

How Installing Energy-Efficient Windows in Dover Saves You Money

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

  • 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 Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
  • Reduce your carbon footprint: In Dover, you can reduce your indirect greenhouse gas emissions by about 286 pounds per year once you switch to energy-efficient windows.
  • Save on electricity bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save around $313 annually on your energy bills in Dover.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in Dover

Windows come in varying purposes, shapes and styles, so costs and services will vary greatly depending on your project. Below, we describe the average cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

Generally, Dover homeowners can anticipate their window installations to range from $250 to $1,200. The average cost is at about $600. But costs will differ considerably depending on the current condition of your home, your location, the number of windows you need and the quality of your products. Many window companies also offer door installations and other add-ons like coating, baths, shutters and more. These extra services will increase your overall project costs.

It's also worth noting that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your Dover home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Asking for free quotes from several installers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?

Full-frame installations are usually done when you want a new style or your window has a lot of rot. With this service, your installers will replace the entire window, including the trim, sill and frame. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

Your window installation company can recommend the best type for your project. In Dover, the decision will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Dover

EcoWatch reviews are different from most reviews because we examine these companies through a sustainability lens. We've assessed the top window installation companies in Dover mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Dover, we gave more points to companies that serve 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

When choosing new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers higher marks 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 consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, warranty, professionalism, cost, quality of installation and more.

Cost

This one is a give-and-take: similar to most services, cheap window installers won't always provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.

Warranty

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

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

The average cost of replacing a single window ranges from $450 to $650. There are a variety of factors that influence how much it costs, such as local labor costs, how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows, your property's location and the number of windows.

Which kind of window should I get?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do.
