How Installing Energy-Efficient Windows in West Deer Saves You Money
There are several benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help reduce that number, which helps you save more on your bills.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Decrease your carbon footprint: By using less energy once switching to Energy Star certified windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in West Deer
Windows come in various shapes and sizes, so costs and services will differ greatly. Here are the average costs and services that you can find from window installers.
How Much Do New Windows Cost?
According to our research, the national average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. How much it will cost is based on several factors, including number of windows, size, material, the location of your home, type and more.
With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save West Deer homeowners $313+ a year after replacing single-pane windows.
Costs will also vary based on the material you pick 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 provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive 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 step when considering a replacement is to figure out whether you should get a full-frame or pocket installation.
A full-frame installation is a replacement of the total window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, like insulation and drip edges, which raise the total cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
If you’re still trying to decide which kind of installation to get, you can consult with your installer and get their recommendation. The choice mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in West Deer
The EcoWatch Reviews team differs from most reviewers, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in West Deer and ranked them based on the following methodology:
Service Area
Since this is a guide for West Deer, we only included companies that serve the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in West Deer.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have positive feedback about their experience with a certain installer, it won’t be featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we awarded higher points 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 make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to West Deer’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of West Deer window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
West Deer, PA Window Replacement FAQs
What is the average cost to replace windows in a home?
The typical cost to replace one window ranges between $450 and $650. There are several factors that influence how much it costs, including how energy-efficient the windows are, your property’s location, the materials used in designing the windows, styles and sizes of windows, local labor costs and the number of windows.
Which kind of window should I get?
A window’s energy efficiency is influenced by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
Can you replace your own windows?
If you’re handy and have the time and patience to do the job right, it’s possible to install your own windows. However, if you don’t have the time or know-how, we recommend getting a professional to do it for you.
How often should you replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may need to be replaced.
