How Installing Energy-Efficient Windows in El Cajon Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
• Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 117 pounds.
• Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Installing energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
• Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.

Estimated Cost of Window Replacement in El Cajon

When researching window installation, each company provides varying services and prices. Let's look at some typical costs and services.

How Much Do New Windows Cost?

The national average cost to install one window is about $600 but can range from $200 to $1,200. But prices differ 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 installations and replacements, which will make your project cost more.

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 replace single-pane windows and between $27 and $197 per 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.

Getting free quotes from several installers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

Generally, there are two types of window installation services you can get: full-frame and pocket installations.

Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the full window, including the sill, trim and frame. A pocket installation involves replacing a window within the frame that's already there. This means instead of taking out the whole window 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 recommend the best type for your project. In El Cajon, the choice will mostly be influenced by how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in El Cajon

In our hunt to find the most reliable, eco-friendly window installers in El Cajon, EcoWatch assessed many companies before landing on these. We've evaluated the best window replacement companies in El Cajon mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for El Cajon, we paid more attention to companies that serve the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in El Cajon.

Work Quality

When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. 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

We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, cost, quality of parts, quality of installation, warranty and more.

Cost

This one is a give-and-take: similar to most services, cheap window installers won't always provide the most 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

As discussed, windows are a substantial investment, so you'll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor 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 years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
