Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although environmentally friendly 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 large impact on home energy conservation. During the hot summer months, the last thing you want is your cool air to leak out of your outdated windows.

That's also bad news for the environment because the additional energy required by drafty windows increases your carbon footprint.

So if you're constructing a new home, renovating or replacing your windows in Glendora, this guide is the best place to get started.

How Installing Energy-Efficient Windows in Glendora Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could help you:

  • Decrease your carbon footprint: By using less energy once upgrading to energy-efficient windows, you'll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
  • Save on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
  • 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.

Estimated Cost of Window Replacement in Glendora

Windows come in varying shapes and sizes, so costs and services will differ considerably. Here are the typical costs and services that you can find from window installers.

How Much Do New Windows Cost?

Generally, Glendora homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. But costs will vary significantly based on your location, the quality of your products, the current condition of your home and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. These extra services will increase overall project costs.

It's important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Glendora homeowners $509+ a year when replacing single-pane windows.

Getting free quotes from several installers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the complete window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. Full-frame installations are more involved and will raise overall costs. A pocket installation entails replacing a window without taking out the entire frame, which tends to be less expensive than a full-frame installation.

If you're unsure which window installation service you need, your installer can assist you. Generally, the decision depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Glendora

The EcoWatch Reviews team differs from other reviewers since we assess these companies through a sustainability lens. We have assessed the best window installation companies in Glendora mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we've chosen to highlight window installation companies that serve Glendora so you can find a quality window installation company near you.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each installer included on this list to ensure its contractors are well-qualified and that the company has gotten tons 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, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installers won't always provide the highest quality service. Still, we want to ensure we're highlighting companies that provide a wide 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 offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Glendora, CA Window Replacement FAQs

What is the average cost to install new windows?

The national average cost to install a window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is generally dependent on the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

Which type of window should I get?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.

Can you replace your own windows?

While it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Using a window replacement company can help ensure that the installation is done properly and that you won't have to spend the time and effort to do it yourself.

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

Windows typically have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have them checked by an expert to see if they need any repairs or replacements.
