How Installing Energy-Efficient Windows in Los Angeles Saves You Money
By switching to energy-efficient windows, you can enjoy several benefits, including:
- Better temperature control in your home: Energy-efficient windows can reduce how hard your heating system needs to work to heat your home.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Save money on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
Estimated Cost of Window Replacement in Los Angeles
Let's take a look at the cost of window replacement and the kinds of services you may need for your home.
How Much Do New Windows Cost?
According to our market research, the typical cost to replace a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. These figures vary based on specific characteristics of your installation, such as size, material, the location of your home, type, number of windows and more.
Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $509 a year on your energy bills in Los Angeles.
Something else that affects the total cost is the material you choose for your frame. Aluminum frames are typically the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first thing to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?
A full-frame installation replaces the complete window, including the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installation company can recommend the best type for your project. In Los Angeles, the decision will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Los Angeles
The EcoWatch Reviews team is different from most reviewers because we assess these companies through a sustainability lens. We have evaluated the top window replacement companies in Los Angeles mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve Los Angeles 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 factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have nice things to say about their service from a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window companies may not provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Los Angeles, CA Window Replacement FAQs
What is the average cost to replace windows in a home?
The national average cost of replacing a single window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is often dependent on the size of the window, the type and material of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the most common kinds of replacement windows?
The most common types of windows for homes include: transom windows, casement windows, bay windows, picture windows, awning windows, double-hung and single-hung windows and slider windows.
Do you really have to use a window installation company?
Unless you have home repair skills and have all the tools you need to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and safer alternative.
How long does it generally take to install windows?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.
