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 lowering your carbon footprint, improving your house’s energy efficiency can also have a large impact on home energy conservation. If your windows are made of traditional materials, or are outdated or damaged, you could be sending 25-30% of your house’s heat or cool air right out of them.

Fortunately, saving you money with more efficient windows also helps our goals of reducing energy usage for the environment.

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

Covina Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in 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 Covina Saves You Money

By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:

  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Reduce your carbon footprint: In Covina, you can lower your indirect greenhouse gas emissions by about 117 pounds per year once you upgrade to energy-efficient windows.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
  • Save on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in Covina

Let’s go over the cost of window replacement and the types of services offered by installers.

How Much Do New Windows Cost?

The typical cost to replace one window is about $600 but can range anywhere from $200 to $1,200. These estimates vary based on specific characteristics of your installation, such as the location of your home, material, number of windows, type, size and more.

With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Covina homeowners $509+ per year after replacing single-pane windows.

The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are generally 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 shown to be more efficient.

What Services do Window Installers Offer?

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

A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve other materials, including insulation and drip edges, which raise the overall cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation means replacing a window without taking out the entire frame, which is generally less expensive than a full-frame installation.

Your window installation company can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Covina

EcoWatch differs from other reviewers since we assess these companies through a sustainability lens. We have decided to assess the best window replacement companies in Covina mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

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

Work Quality

When picking new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have good feedback about their experience with a certain installer, 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 as low as possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide 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 a proven track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Covina, CA Window Replacement FAQs

What is the average cost to install windows?

The national average cost of installing a window is about $600 but can range from $200 to $1,200, based on several factors. The price is often dependent on the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What are the most common types of replacement windows?

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

Can I install my own windows?

If you’re handy and know how to replace a window, it’s possible to install your own windows. But if you don’t have the time or experience, we don’t recommend it.

What time of year is a good time to replace my windows?

Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the home, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.

Should I replace my windows all at once?

If you want to get more efficient windows and save money on your energy bills, replacing all the windows at once is the only way to gain that benefit. However, if you have only one or two windows that are damaged or leaky, you can replace just those.
