How Installing Energy-Efficient Windows in Duarte Saves You Money

When you switch to energy-efficient windows, you may see some benefits, such as:

  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Duarte, that’s about 117 pounds per year on average.
  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save on energy bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save about $509 annually on your energy bills in Duarte.

Estimated Cost of Window Replacement in Duarte

Let’s go over the cost of replacing your windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

Even though the average cost of installing one window is about $600, it can range anywhere from $200 to $1,200. But costs will vary significantly 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 door installations and other add-ons like coating, baths, shutters and more. Additional services will increase overall project costs.

It’s also worth noting that energy-efficient windows will usually cost more upfront, but Energy Star predicts that switching out the windows on your Duarte home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

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

What Services do Window Installers Offer?

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

A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. As this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installation company should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Duarte

The EcoWatch Reviews team differs from most reviewers because we’re examining these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Duarte and assigned rankings using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer featured in our guide to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have nice feedback about their experience with a certain installer, it won’t be featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Duarte’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Duarte window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Duarte, CA Window Replacement FAQs

What is the average cost to replace windows in a home?

The typical cost to install a single window can range from $450 to $650. There are several factors that influence the cost, such as how energy-efficient the windows are, local labor costs, the materials used in designing the windows, the number of windows, your property’s location and styles and sizes of windows.

What are the most common kinds of replacement windows?

The most common kinds of windows for homes include: casement windows, slider windows, awning windows, picture windows, double-hung and single-hung windows, bay windows and transom windows.

Can you install your own windows?

If you’re handy and know how to replace a window, you may be able to install your own windows. But if you don’t have the time or experience, we recommend getting a professional to do it for you.

How do you know it’s time to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
