How Installing Energy-Efficient Windows in Kennett Square Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could benefit you:

  • Better temperature control in your home: When you reside in a place like Kennett Square where the summers can be quite hot, you usually need to depend on your air conditioner to keep your home cool. Energy-efficient windows can lower how hard your AC needs to work to cool your home.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Kennett Square, that's about 286 pounds per year on average.
  • Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its value.
  • More efficient energy use in your home: Because the winters can get very cold in Kennett Square, homeowners usually rely on their heater during that time. Energy-efficient windows decrease how much heat is lost through your windows, making it easier to keep your home warm.

Estimated Cost of Window Replacement in Kennett Square

Let's take a look at the cost of replacing your windows and the types of services offered by installers.

How Much Do New Windows Cost?

According to our research, the national average cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. Costs will differ significantly based on the current condition of your home, the quality of your products, your location and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like shutters, baths, coating 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 upgrading the windows on your Kennett Square home can mean an average energy savings of $236 to $319 a 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 installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Another factor that affects the overall cost is the material you pick for your frame. Aluminum frames are usually the least expensive 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 as well and cost somewhere between the other two.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services you can get: full-frame and pocket installations.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation means replacing a window without removing the whole frame, which is generally cheaper than a full-frame installation.

If you're hiring a reputable window installation company, your company can recommend the best type for your project. In Kennett Square, the choice will mostly be influenced by the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Kennett Square

In our hunt to find the most reliable, eco-friendly window installers in Kennett Square, the EcoWatch team evaluated dozens of companies before landing on these. We have assessed the best window installation companies in Kennett Square mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Kennett Square so you can find a quality window installation company near you.

Work Quality

When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do give window installers higher marks if they offer high-quality products, but we also factor in 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. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of parts, quality of installation, warranty, professionalism, cost and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
