How Installing Energy-Efficient Windows in Dover Saves You Money
There are several benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Replacing your windows with energy-efficient models can help lower that number, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 286 pounds per year on average.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- 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 Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way.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.
Estimated Cost of Window Replacement in Dover
Windows come in all shapes and sizes, so costs and services will differ tremendously. Here are the typical costs and the primary services that you’ll find from the average window installation company.
How Much Do New Windows Cost?
According to our market research, the typical cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. This is because the cost of window installations are based 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.
It’s also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star estimates 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 a year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are usually the most expensive, but it depends on whether they are solid 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 considering a window replacement is: Do you want a full-frame installation or a pocket installation?
Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of deterioration. With this service, your professionals will replace the whole window, including the trim, frame and sill. Pocket installations are simpler and won’t carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.
Your window installation company will be able to help you understand what’s best for your needs. In Dover, the decision will mostly depend on how old your windows are and if there’s any moisture damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Dover
In our hunt to make your home improvements easier and more eco-friendly in Dover, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed several window installers in Dover and ranked them based on the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the right 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 included on this list to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have nice things to say about their service from a certain company, you won’t see it featured on EcoWatch.
Cost
Cheaper windows don’t necessarily 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
As discussed previously, windows are a significant investment, so you’ll want to make sure that investment is protected. Window installation companies that have 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, low efficiency and rot. 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.
