How Installing Energy-Efficient Windows in Westmont Saves You Money

There are quite a few benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:

• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
• Decrease your carbon footprint: In Westmont, you can cut your indirect greenhouse gas emissions by about 449 pounds per year when you upgrade to energy-efficient windows.
• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
• Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that number, which helps you save $300 a year on your bills.

Estimated Cost of Window Replacement in Westmont

Each window installer offers various services and has varying price points depending on a few factors.

How Much Do New Windows Cost?

The national average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. But costs will vary considerably based on the number of windows you need, the current condition of your home, the quality of your products and your location. A lot of window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. Additional services will increase your overall project costs.

With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Westmont homeowners $300+ a year after replacing single-pane windows.

How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are typically the most expensive, though it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

There are generally two kinds of window installation services: full-frame and pocket installations.

Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your installers will replace the whole window, including the frame, sill and trim. A pocket installation means replacing a window within the existing frame, which is generally less expensive than a full-frame installation.

If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In Westmont, the choice will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Westmont

EcoWatch differs from other reviewers since we’re examining these companies through a sustainability lens. We have reviewed the top window installers in Westmont primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Westmont, we only included companies that serve the city. There are certainly reputable providers that didn’t make our 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 looking for a company to do a great job installing windows. We’ve vetted each company in our guide to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If most customers don’t have nice feedback about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed previously, windows are a significant investment, so you’ll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Westmont’s climate, homeowners need to be wary of rot, low efficiency and water damage. 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.
