How Installing Energy-Efficient Windows in Fontana Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here's more information on how switching out your windows could help you:

• Decrease your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 117 pounds per year on average.
• Save money on electricity bills: Because energy-efficient windows reduce the amount of energy used to heat or cool your home, they can help you save around $540 annually on your energy bills in Fontana.
• 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 Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way.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 increase the value of your home if you decide to sell.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Fontana

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?

Although the typical cost of installing a single window is around $600, it can range anywhere from $200 to $1,200. These numbers vary depending on the specifics of your installation, such as number of windows, type, size, the location of your home, material and more.

It’s also worth noting that energy-efficient windows will typically cost more upfront, but Energy Star estimates that switching out the windows on your Fontana home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Another factor that influences the overall cost is the material of the frame you choose. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

There are typically two types of window replacement services: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which raise the overall cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations are on the simpler end and won’t cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.

Your window installation company will be able to recommend the best type for your project. In Fontana, the choice will mostly depend on the efficiency of your home and the age of your existing frames.
