How Installing Energy-Efficient Windows in Dover Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are a few reasons you may want to consider making the switch:
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
- Save on power bills: Once you install 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.
Estimated Cost of Window Replacement in Dover
Windows come in various shapes and sizes, so costs and services will differ greatly. Here are the typical costs and services that you'll find from the average window installation company.
How Much Do New Windows Cost?
On average, Dover homeowners can expect their window installations to range from $250 to $1,200. The average cost is at around $600. This is because of the fact that the cost of window installations are based on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
It's important to keep 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 certified energy-efficient windows can save Dover homeowners $339+ a year when replacing single-pane windows.
Another factor that affects the total cost is the material you choose for your frame. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first question to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations are usually recommended when you want a new style or your window has a lot of rot or deterioration. With this service, your professionals will replace the complete window, including the sill, trim and frame. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installation company should be able to help you figure out what's best for your needs. In Dover, the decision will mostly depend on how old your windows are 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
In our search to find the most reliable, eco-friendly window installers in Dover, the EcoWatch team chose 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
Because this is a guide for Dover, we gave more points to companies that cover the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Dover.
Work Quality
When choosing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you choose. 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 customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including professionalism, quality of installation, cost, quality of parts, warranty and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies are not going to provide the highest quality service. Still, we want to ensure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a substantial investment, so you'll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Dover's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Dover window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Dover, NY Window Replacement FAQs
How much does window installation cost?
The national average cost of installing one window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is generally dependent on the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which type of window should I get?
Generally, double-pane windows will be 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'll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies do?
Window installation professionals will do the entire process — from replacing your old windows with brand new ones to cleaning up after the windows have been put in place. Additionally, many companies offer window manufacturing, customization and repairs.
How often should you replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all the windows at the same time is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are damaged or leaky, you can replace just those.
