How Installing Energy-Efficient Windows in Westmont Saves You Money

Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to make the switch:

• Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 117 pounds.
• Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
• Save on electricity bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your home.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.

What Services do Window Installers Offer?

When considering window installations, in general there are two types that your installer will have: full-frame and pocket installations.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re still trying to decide which type of installation to get, you can consult with your provider and get their recommendation. The decision mostly is influenced by how old the frames are and if there’s any damage present.

We’ve evaluated the top window replacement companies in Westmont mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can cut 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 paid more attention to companies that serve the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Westmont.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included 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 online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, cost, professionalism, quality of parts, warranty and more.

Cost

This one is a give-and-take: as with most services, cheap window installers won’t always provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Westmont’s climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Westmont window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
