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 ways switching out your windows could benefit you:

  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
  • Reduce your carbon footprint: In Kennett Square, you can lower your indirect greenhouse gas emissions by about 286 pounds per year once you switch to energy-efficient windows.
  • Save on electricity bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $310 annually on your energy bills in Kennett Square.

Estimated Cost of Window Replacement in Kennett Square

Windows come in all shapes and sizes, so costs and services will vary tremendously. Here are the average costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

On average, homeowners in Kennett Square can anticipate that most replacement window installations will cost between $250 and $1,200, with the average cost sitting at around $600. This is because the cost of window installations are based on several factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.

It's important to bear 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 Kennett Square homeowners $310+ a year when replacing single-pane windows.

Costs will also vary depending on the material you choose for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

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 a new style or your window has a lot of deterioration. With this service, your installers will replace the full window, including the trim, frame and sill. A pocket installation involves installing a new window within the old frame. So, instead of tearing out the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can advise you on the best type for your project. In Kennett Square, the choice will mostly be based on the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Kennett Square

In our search to find the most reliable, eco-friendly window installers in Kennett Square, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed several window installers in Kennett Square and ranked them based on the following methodology:

Service Area

This one is pretty 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 willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer 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 the majority of customers don't have good things to say about their service from a certain installer, it won't be featured on EcoWatch.

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 the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important. That's why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Kennett Square's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Kennett Square window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Kennett Square, PA Window Replacement FAQs

How much does window installation cost?

The typical cost of installing one window can range from $450 to $650. There are many factors that affect how much it costs, which include how energy-efficient the windows are, your property's location, local labor costs, the materials used in designing the windows, the number of windows and styles and sizes of windows.

What type of window is the most energy-efficient?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.

Do I really have to use a window installation company?

Unless you have experience with home improvement projects and have the tools needed to replace your own windows, we recommend hiring a professional. The window installation process is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer option.

When is the best time of year to replace windows?

Although you can install windows any time of year, warmer weather is generally better for installing replacement windows. In addition, it shouldn't be raining, because rain can make the installation harder.

Should I replace all my windows at the same time?

If your windows are greater than 20 years old, you most likely need to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
