How Installing Energy-Efficient Windows in Monrovia Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to take the plunge and make the switch:
- Save money on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
- 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.
- 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.
Estimated Cost of Window Replacement in Monrovia
Windows come in all shapes and sizes, so costs and services will vary considerably. Here are the typical costs and services that you'll find from window installation companies.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range from $200 to $1,200. How much it will cost you varies depending on several factors, including material, size, the location of your home, number of windows, type and more.
It's important to bear in mind 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.
We advise requesting free quotes from several window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
The first step when planning an installation is to clarify 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. Because this type of installation requires more time, it will be more expensive than a pocket installation. Pocket installations are on the simpler end and won't carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.
Your window installation company can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Monrovia
EcoWatch reviews differ from most reviews because we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the Monrovia area so you can find the right window installation company near you.
Work Quality
When it comes to new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, quality of installation, warranty, quality of parts, cost and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies won't always provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a significant investment, so you'll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and labor 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 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 average cost to replace windows?
The national average cost to replace one window is about $600 but can range between $200 and $1,200, depending on several factors. The price is generally influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common kinds of replacement windows?
There are several different types of windows you can get for your house, such as bay windows, casement windows, picture windows, double-hung and single-hung windows, transom windows, awning windows and slider windows.
What services do window replacement companies do?
Window installation professionals travel to your house to remove your old windows and replace them with new ones. Some companies install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation.
What time of year should I replace my windows?
Even though you can install windows any time of year, warmer weather is usually better for replacing windows. Additionally, the weather should be dry, because rain can make the installation harder.
How do you know it's time to replace your windows?
Windows typically last around 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have an expert take a look at them to determine if they are in need of a repair or replacement.
