How Installing Energy-Efficient Windows in Westlake Village Saves You Money

When you upgrade to energy-efficient windows, you may see a few perks, including:

  • Save on power bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, they can help you save around $509 annually on your energy bills in Westlake Village.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if you have an older home.
  • Decrease your carbon footprint: By using less energy after you switch to energy-efficient windows, you'll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in Westlake Village

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

How Much Do New Windows Cost?

Even though the typical to replace a single window is around $600, it can range from $200 to $1,200. These figures are based on specific characteristics of your installation, including number of windows, the location of your home, material, type, size and more.

Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $509 a year on your energy bills in Westlake Village.

Requesting free quotes from several companies is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

In general, there are two types of window replacement services companies offer: full-frame and pocket installations.

Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant deterioration. With this service, your installers will replace the full window, including the sill, frame and trim. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and will be less expensive, 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 you should get, you can talk to your installer and get their recommendation. The decision 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 Westlake Village

The EcoWatch Reviews team is different from most reviewers since we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Westlake Village and assigned rankings based on the following methodology:

Service Area

Since this is a guide for Westlake Village, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Westlake Village.

Work Quality

When it comes to new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including professionalism, quality of installation, quality of parts, warranty, cost and more.

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 scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a serious investment, so you'll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

There are several different types of windows you can get for your house, including casement windows, picture windows, bay windows, awning windows, transom windows, slider windows and double-hung and single-hung windows.

Can I replace my own windows?

Even though you can install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help guarantee that the installation is done properly and that you won't have to spend the time and effort to do it yourself.

When is the best time of year to replace windows?

Replacement windows can be installed any time of the year, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to make sure 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.
