West Covina Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in West Covina, CA using our customized window cost calculator.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in West Covina Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more ways switching out your windows could help you:

  • Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
  • Save money on power bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.
  • Decrease your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 117 pounds per year on average.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in West Covina

Windows come in different shapes and sizes, so costs and services will differ considerably. Here are the average costs and the primary services that you’ll find from the average window installation company.

How Much Do New Windows Cost?

Generally, West Covina homeowners can expect their window installations to range from $250 to $1,200. The average cost is at about $600. This is because window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.

With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save West Covina homeowners $509+ each year after replacing single-pane windows.

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

What Services do Window Installers Offer?

The first question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

A full-frame installation is a replacement of the total window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the overall cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

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

How We Choose the Best Window Installers in West Covina

In our search to find the most reliable, eco-friendly window installers in West Covina, EcoWatch evaluated many companies before settling on these. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve West Covina so you can find the best window installation company near you.

Work Quality

When it comes to new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most 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 nearly every category, including quality of parts, cost, professionalism, quality of installation, warranty and more.

Cost

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

Warranty

As discussed, windows are a hefty investment, so you’ll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

West Covina, CA Window Replacement FAQs

How much does window installation cost?

The typical cost to install a single window ranges between $450 and $650. There are many factors that affect how much it costs, such as your property’s location, the materials used in designing the windows, styles and sizes of windows, how energy-efficient the windows are, local labor costs and the number of windows.

Which kind of window is the best?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.

Do I really have to use a window installation company?

You should use a window installation professional whenever you need new windows. Installing windows is a complicated process that can be difficult and time-consuming, so it’s best left to the professionals.

How long does it take to install windows?

Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you have a lot of windows that need to be installed.
