How Installing Energy-Efficient Windows in Monrovia Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how upgrading your windows could help you:
- Save on energy bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.
- Reduce your carbon footprint: In Monrovia, you can cut your indirect greenhouse gas emissions by about 117 pounds per year once you switch to energy-efficient windows.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Monrovia
When considering window installation, each company offers different services and costs. Let’s look at some average costs and services.
How Much Do New Windows Cost?
The typical cost to install one window is about $600 but can range anywhere from $200 to $1,200. This is because window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.
It’s important to note that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Monrovia homeowners $509+ a year when replacing single-pane windows.
Requesting free quotes from multiple companies is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first question to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are simpler and won’t carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
If you’re still trying to decide which type of installation you need, you can talk to your provider and get their recommendation. The choice mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Monrovia
EcoWatch differs from most reviewers, as we examine these companies through a sustainability lens. We have evaluated the best window replacement companies in Monrovia mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Monrovia, we only included companies that cover the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Monrovia.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company featured in our guide to ensure its contractors are well-qualified and that the company has received lots 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 may be the most important factor, as it reflects the quality of services across nearly every category, including cost, quality of parts, professionalism, warranty, quality of installation and more.
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 wide range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a substantial investment, so you’ll want to be certain that investment is well protected. Window installation companies that have 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 experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Monrovia, CA Window Replacement FAQs
What is the typical cost to install windows in a home?
The typical cost to replace a window ranges between $450 and $650. There are a variety of factors that affect how much it costs, including your property’s location, the materials used in designing the windows, local labor costs, the number of windows, styles and sizes of windows and how energy-efficient the windows are.
What type of window is the most energy-efficient?
A window’s energy efficiency is affected by a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
What do window installation companies do?
Window installation professionals visit your home 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 complete.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your home, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.
