How Installing Energy-Efficient Windows in Mission Viejo Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Save money on electricity bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll require less energy to heat or cool your house.
- Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Mission Viejo
Let’s take a look at the cost of updating your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Though the typical cost to install one window is around $600, it can range anywhere from $200 to $1,200. But costs vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which carry a higher price tag.
It’s important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Mission Viejo homeowners $388+ a year when replacing single-pane windows.
Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. 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 provide decent insulation for your home.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will cost more than a pocket installation. A pocket installation means replacing a window without taking out the whole frame, which tends to be less expensive than a full-frame installation.
Your window installation company should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Mission Viejo
In our hunt to find the most reliable, eco-friendly window installers in Mission Viejo, the EcoWatch Reviews team examined dozens of companies before landing on these. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Mission Viejo, we gave more points to companies that serve the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Mission Viejo.
Work Quality
When picking new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you choose. We do give window installers more points if they offer high-quality products, but we also consider 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 company, you won’t see it featured on EcoWatch.
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 awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a serious investment, so you’ll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
