How Installing Energy-Efficient Windows in Rancho Santa Margarita Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more ways switching out your windows could help you:

• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
• Save on energy bills: Since energy-efficient windows lower the amount of energy used to heat or cool your home, they can help you save about $388 annually on your energy bills in Rancho Santa Margarita.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
• Reduce your carbon footprint: In Rancho Santa Margarita, you can lower your indirect greenhouse gas emissions by about 117 pounds per year after you install energy-efficient windows.

Estimated Cost of Window Replacement in Rancho Santa Margarita

Each window replacement company provides varying services and has different costs based on several factors.

How Much Do New Windows Cost?

Generally, homeowners in Rancho Santa Margarita can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. These figures are based on specific characteristics of your installation, like the location of your home, type, number of windows, material, size and more.

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

The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

There are generally two types of window installation services: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which raise the total cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves replacing a window within the old frame. This means instead of removing the whole unit and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company will be able to advise you on the best type for your project. In Rancho Santa Margarita, the decision will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Rancho Santa Margarita

In our search to find the most reliable, eco-friendly window installers in Rancho Santa Margarita, the EcoWatch Reviews team assessed many companies before landing on these. We’ve evaluated the best window installers in Rancho Santa Margarita primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Rancho Santa Margarita, we gave more points to companies that cover the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Rancho Santa Margarita.

Work Quality

When it comes to new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window 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 the majority of customers don’t have nice feedback about their experience with a certain window installation 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 want to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed previously, windows are a substantial investment, so you’ll want to make sure 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 installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
