Why you can trust EcoWatch
Although green energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's energy efficiency can also have a big impact on home energy conservation. If you have traditional, outdated windows, your AC or heater could be working overtime to heat or cool your home. This means spending more on power bills.
Replacement windows improve the insulation in your home, not only making you more comfortable during extreme temperatures, but also saving you money and helping the environment.
Efficient windows are especially important in Westmont, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $300 per year.

Calculate how much you can expect to pay for window installation and replacement in Westmont, IL using our customized window cost calculator.

How Installing Energy-Efficient Windows in Westmont Saves You Money
When you switch to energy-efficient windows, you may see some perks, such as:
- Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient windows can help lower that amount, which helps you save more on your bills.
- More efficient energy use in your home: In Westmont where the winters can get very cold, energy-efficient windows cut back on how much heat is lost through your windows, which makes it easier to keep your home warm.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Westmont
Windows come in all shapes and sizes, so costs and services will differ tremendously. Here are the typical costs and the primary services that you'll find from the average window installation company.
How Much Do New Windows Cost?
The national average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. These estimates are based on specific characteristics of your installation, such as number of windows, type, the location of your home, size, material and more.
Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $300 a year on your energy bills in Westmont.
Another factor that influences the total cost is the material of the frame you pick. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. This service involves removing the old window, the sill, and the exterior and interior trim. It can also involve other materials, including 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 around the window after a full-frame installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you're still debating which kind of installation you need, you can ask your provider and get their recommendation. The choice mostly is influenced by the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Westmont
In our hunt to make your home improvements easier and more eco-friendly in Westmont, EcoWatch chose the above companies as the top window installation companies in the city. We have reviewed the best window replacement companies in Westmont primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Westmont, we only included companies that serve the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Westmont.
Work Quality
When choosing 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 opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, professionalism, cost, warranty, quality of parts and more.
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
As discussed previously, windows are a considerable investment, so you'll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Westmont's climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Westmont window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Westmont, IL Window Replacement FAQs

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

Can I replace my own windows?
