Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home's energy efficiency can also have a big impact on home energy conservation. Poor windows can decrease your home's energy efficiency by up to 30%, according to the Department of Energy. In Cornwall, that's almost $287 per year that you could save on your electric bills by making the switch.
Thankfully, saving you energy with efficient windows also helps our goals of reducing energy usage for the environment.
Efficient windows are of particular importance in Cornwall, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $287 a year.

How Installing Energy-Efficient Windows in Cornwall Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here's more information on how upgrading your windows could benefit you:
- Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Save on power bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your home.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Cornwall
When looking into window installation, each company offers different services and costs. Let's go over some typical costs and services.
How Much Do New Windows Cost?
Typically, Cornwall homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at about $600. These figures vary depending on the specifics of your installation, like the location of your home, type, material, number of windows, size and more.
It's important to remember 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 Energy Star certified windows can save Cornwall homeowners $287+ a year when replacing single-pane windows.
Costs will also vary based on the material you choose for your window frames. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the complete window, including the frame, sill and trim. A pocket installation involves installing a new window within the old frame. So, instead of tearing out the whole window and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're still trying to decide which kind of installation you should get, you can talk to your provider and get their advice. The choice mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Cornwall
EcoWatch is different from most reviewers, as we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Cornwall so you can find the right window installation company near you.
Work Quality
When selecting new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have positive feedback about their service from a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, 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 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 good track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Cornwall, PA Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing a single window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is often influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the different kinds of windows?
There are several different kinds of windows you can get for your home, such as picture windows, slider windows, bay windows, double-hung and single-hung windows, casement windows, transom windows and awning windows.
What services do window installation companies do?
Window installation professionals cover the entire process — from replacing old windows with new ones to cleaning up after the installation. Additionally, many companies offer window manufacturing, customization and repairs.
When is it time to replace your windows?
Windows usually have a lifespan of around 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have them looked at by an expert to see if they need any repairs or replacements.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it's probably time to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
