How Installing Energy-Efficient Windows in Mountain Top Saves You Money
Switching 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 help you:
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 286 pounds per year on average.
- Save money on energy bills: Once you switch 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.
Estimated Cost of Window Replacement in Mountain Top
Each window installation company offers varying services and has different price points depending on a few factors.
How Much Do New Windows Cost?
Even though the national average cost to replace one window is about $600, it can range from $200 to $1,200. This is because the cost of window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.
It’s important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Mountain Top homeowners $329+ a year when replacing single-pane windows.
Something else that affects the total cost is the material of the frame you choose. Aluminum frames are usually the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
When it comes to window replacements, in general there are two kinds that your provider will have: full-frame and pocket installations.
A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. As this type of installation requires more time, it will be more expensive than a pocket installation. A pocket installation means replacing a window without taking out the whole frame, which is generally cheaper than a full-frame installation.
Your window installer should be able to help you choose which type of installation you need.

Mountain Top, PA Window Replacement FAQs
What is the average cost to install new windows in a home?
The national average cost to replace a window is about $600 but can range between $200 and $1,200, based on several factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the most common types of replacement windows?
The most common kinds of windows for homes include: awning windows, bay windows, slider windows, transom windows, double-hung and single-hung windows, casement windows and picture windows.
What services do window replacement companies do?
Window installation professionals visit your house to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.
What time of year is the best time to replace my windows?
Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the house, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.
How often do you need to replace your windows?
Windows usually have a lifespan of about 20 to 30 years, but anytime you see damage on your windows, it’s a good time to have an expert take a look at them to see if they need any repairs or replacements.
