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 switching to energy-efficient windows, you and your family can benefit in several ways, such as:

  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
  • Better temperature control in your home: Energy-efficient windows can reduce how much heat is lost through your windows when heating your home.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in Covina

When researching window installation, each company provides varying services and prices. Let's look at some average costs and services.

How Much Do New Windows Cost?

Although the average to replace a single window is around $600, it can range anywhere from $200 to $1,200. Costs will vary significantly depending on the number of windows you need, the current condition of your home, your location and the quality of your products. Many window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. These extra services will increase your overall project costs.

Bear in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Costs will also vary depending on the material you pick for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first step of a window replacement is to figure out whether you want a full-frame or pocket installation.

A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will be more expensive than a pocket installation. A pocket installation means replacing a window within the existing frame, which is generally cheaper than a full-frame installation.

Your window installer can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Covina

In our hunt to find the most reliable, eco-friendly window installers in Covina, EcoWatch chose the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed window companies all across the state and ranked them based on the following methodology:

Service Area

Because this is a guide for Covina, we only included companies that provide services to the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Covina.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each company included on this list 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

We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including professionalism, warranty, quality of parts, quality of installation, cost and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try 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

As discussed previously, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Covina's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of 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.

Covina, CA Window Replacement FAQs

What is the typical cost to install windows in a home?

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

What kind of window is the most energy-efficient?

A window's energy efficiency depends on a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

What do window installers do?

Window installation professionals go to your house to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.

How often should you replace windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to operate, they may need to be replaced.

Should I replace my windows all at once?

If your windows are more than 20 years old, it's most likely time to replace all of them. At that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
