How Installing Energy-Efficient Windows in Hockessin Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how upgrading your windows could benefit you:
- Save money on energy bills: Installing energy-efficient windows lowers your energy bills by about 12% since you need less energy.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Decrease your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Hockessin
Let’s go over the cost of window installation and the kinds of services you may need for your home.
How Much Do New Windows Cost?
The national average cost to install one window is about $600 but can range from $200 to $1,200. This is because of the fact that window installations are based on a variety of 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 also worth bearing in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading the windows on your Hockessin home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
We recommend getting free quotes from several window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
The first question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations are usually recommended when you want a new style or your window has significant deterioration. With this service, your installers will replace the complete window, including the sill, trim and frame. Pocket installations are simpler and won’t carry as large a bill, as they involve merely replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.
If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In Hockessin, the decision will mostly be influenced by how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in Hockessin
EcoWatch reviews are different from most reviews since we’re examining these companies through a sustainability lens. We have evaluated the best window installers in Hockessin mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve Hockessin so you can find the best window installation company near you.
Work Quality
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company included in our guide to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don’t have nice things to say about their experience with a certain installer, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the most quality service. Still, 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 substantial 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
Because of Hockessin’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Hockessin window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Hockessin, DE Window Replacement FAQs
How much should a window install cost?
The average cost of replacing a single window can range between $450 and $650. There are a variety of factors that affect how much it costs, which include how energy-efficient the windows are, your property’s location, local labor costs, the number of windows, styles and sizes of windows and the materials used in designing the windows.
What kind of window is the most energy-efficient?
A window’s energy efficiency depends on several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
Do I really need to use a window installation company?
Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complicated and can take anywhere from four to six hours for one window. Although it’s tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and much safer option.
How do you know it’s time to replace your windows?
Windows typically last around 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have an expert take a look at them to determine if they need any repairs or replacements.
