How Installing Energy-Efficient Windows in Westmont Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to consider making the switch:
- More efficient energy usage in your household: In Westmont where the summers can be pretty warm, energy-efficient windows decrease the amount of cool air that is lost through your windows, which makes it easier to keep your house cool.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save on energy bills: Installing energy-efficient windows reduces your energy bills by about 12% since you use less energy.
Estimated Cost of Window Replacement in Westmont
Let's take a look at the cost of window installation and the types of services offered by installers.
How Much Do New Windows Cost?
According to our research, the national average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. But costs will vary significantly depending on the current condition of your home, the quality of your products, the number of windows you need and your location. A lot of window companies also offer door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Westmont homeowners $319+ per year after replacing single-pane windows.
Another factor that influences the total cost is the material you select for your frame. Aluminum frames are typically the least pricey 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?
In regard to window replacements, there are generally two types that your installer will offer: full-frame and pocket installations.
Full-frame installations entail replacing the total window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable rot or deterioration. Because full-frame installations are more involved, they will increase the total cost. Pocket installations are on the simpler end and won't cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
Your window replacement company will be able to help you decide what's best for your needs. In Westmont, the decision will mostly depend on how old your windows are and if there's any damage. Wood can decay if it's not maintained properly over the years, so it's a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Westmont
EcoWatch reviews are different from other reviews because we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and assigned rankings using the following methodology:
Service Area
Because this is a guide for Westmont, we only included companies that serve the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Westmont.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company featured in our guide to ensure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, professionalism, warranty, cost, quality of parts and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we awarded higher scores 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 have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Westmont, PA Window Replacement FAQs
How much should a window install cost?
The average cost of replacing a window ranges between $450 and $650. There are several factors that influence how much it costs, such as the number of windows, the materials used in designing the windows, styles and sizes of windows, local labor costs, how energy-efficient the windows are and your property's location.
What type of window is the best for energy efficiency?
A window's energy efficiency is influenced by a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
Can you install your own windows?
If you're handy and have experience with similar home improvement projects, you may be able to install your own windows. However, if you don't have the time or know-how, we don't recommend it.
What time of year should I replace my windows?
Replacement windows can be installed during any season, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.
