How Installing Energy-Efficient Windows in Rancho Santa Margarita Saves You Money
When you upgrade to energy-efficient windows, you may see some benefits, including:
- Decrease your carbon footprint: By using less energy after switching to Energy Star certified windows, you'll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
- Save on power bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient windows can help lower that number, which helps you save some money on your bills.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Rancho Santa Margarita
Windows come in all shapes and sizes, so costs and services will vary tremendously. Here are the average costs and the primary services that you'll find from the average window installation company.
How Much Do New Windows Cost?
Generally, homeowners in Rancho Santa Margarita can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. Costs will vary significantly based on the number of windows you need, the quality of your products, the current condition of your home and your location. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.
It's also worth noting that energy-efficient windows will cost more upfront, but Energy Star estimates that switching out the windows on your Rancho Santa Margarita home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Asking for free quotes from several companies is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
In regard to window installations, in general there are two types that your installer will have: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, like insulation and drip edges, which raise the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won't carry as large a bill, as they entail merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
If you're still trying to decide which kind of installation to get, you can talk to your installer and get their advice. The choice mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Rancho Santa Margarita
EcoWatch reviews are different from other reviews because we look at these companies through a sustainability lens. We have evaluated the top window replacement companies in Rancho Santa Margarita mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Rancho Santa Margarita, we only included companies that provide services to the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Rancho Santa Margarita.
Work Quality
When choosing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you choose. We do give window installers more points 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 experience with a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers may not provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that have 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 a proven track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Rancho Santa Margarita, CA Window Replacement FAQs
How much should window installation cost?
The average cost to install a single window ranges from $450 to $650. There are several factors that affect the cost, which include local labor costs, your property's location, styles and sizes of windows, the number of windows, how energy-efficient the windows are and the materials used in designing the windows.
What are the kinds of windows?
There are various types of windows you can get for your home, including double-hung and single-hung windows, picture windows, casement windows, slider windows, bay windows, awning windows and transom windows.
What services do window installation companies do?

How long does it usually take to install windows?
Since the average installation time of a window is 30 minutes, about 16 windows can be installed during a typical 8-hour work day.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is generally better for installing replacement windows. In addition, the weather should be dry, as rain can make the installation more difficult.
