How Installing Energy-Efficient Windows in Aliso Viejo Saves You Money

When you switch to energy-efficient windows, you may see several benefits, such as:

• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
• Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Aliso Viejo, that’s about 117 pounds per year on average.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Aliso Viejo

Let’s go over the cost of replacing your windows and the types of services you may need for your home.

How Much Do New Windows Cost?

On average, homeowners in Aliso Viejo can anticipate that most replacement window installations will range from $250 to $1,200, with the average cost sitting at about $600. But costs will differ considerably depending on the current condition of your home, your location, the quality of your products and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. Additional services will increase your overall project costs.

Bear in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

In regard to window installations, in general there are two types that your installer will offer: full-frame and pocket installations.

Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot. With this service, your professionals will replace the total window, including the frame, sill and trim. A pocket installation entails replacing a window without removing the complete frame, which tends to be cheaper than a full-frame installation.

Your window installation company can help you choose which type of installation you need.

How We Choose the Best Window Installers in Aliso Viejo

EcoWatch reviews are different from other reviews since we assess these companies through a sustainability lens. We’ve assessed the best window replacement companies in Aliso Viejo primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve the Aliso Viejo area so you can find the right window installation company near you.

Work Quality

When choosing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, quality of parts, professionalism, warranty, cost and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want 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 substantial investment, so you’ll want to be certain that investment is protected. Window installation companies with 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 been in the industry for a while. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
