How Installing Energy-Efficient Windows in Kennett Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to take the plunge and make the switch:
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Installing energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 286 pounds.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Kennett
Let's take a look at the cost of window replacement and the types of services offered by installers.
How Much Do New Windows Cost?
Even though the national average of replacing a single window is around $600, it can range from $200 to $1,200. These estimates vary depending on specific characteristics of your installation, such as size, type, material, the location of your home, number of windows and more.
It's also worth bearing in mind that energy-efficient windows will typically cost more initially, but Energy Star predicts that upgrading the windows on your Kennett home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Another factor that influences the total cost is the material you select for your frame. Aluminum frames are typically the least pricey and are sturdy and light, 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?
In general, there are two types of window installation services companies provide: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. It involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, like insulation and drip edges, which raise the overall cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
If you're still trying to decide which type of installation to get, you can consult with your installer and get their recommendation. The decision mostly depends on the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Kennett
EcoWatch reviews differ from other reviews since we evaluate these companies through a sustainability lens. We've reviewed the best window installation companies in Kennett mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Kennett area so you can find the best window installation company near you.
Work Quality
When it comes to new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you get. 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, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including professionalism, quality of parts, quality of installation, cost, warranty and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a substantial investment, so you'll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Kennett, PA Window Replacement FAQs
What is the average cost to replace windows?
The national average cost of installing a single window is about $600 but can range from $200 to $1,200, depending on several factors. The price is generally dependent on the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which kind of window is the best?
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. If you want to be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.
Can you replace your own windows?
If you're handy and have experience with similar home improvement projects, you may be able to install your own windows. However, if you don't have the time or skills, we recommend hiring a professional.
How long does it typically take to install windows?
Since the average installation time is 30 minutes per window, about 16 windows can be installed in an 8-hour work day.
Should I replace all my windows at the same time?
If you're upgrading your windows to get more efficient windows, replacing all of your windows together is the only way to gain that benefit. On the other hand, if you have only one or two windows that are broken or drafty, you can replace just those.
