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 Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way.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.

How We Choose the Best Window Installers in Fontana

In our search to make your home improvements easier and more eco-friendly in Fontana, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. We have assessed the top window installers in Fontana mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve Fontana so you can find a quality window installation company near you.

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company included on this list to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including warranty, quality of parts, cost, quality of installation, professionalism and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that provide 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 a proven track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Fontana, CA Window Replacement FAQs

How much should a window install cost?

The national average cost to install a single window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is usually dependent on the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What kind of window is the best for energy efficiency?

Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models with the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.

Can I replace my own windows?

If you’re handy and have the time and patience to do the job right, it’s possible to install your own windows. However, if you don’t have the time or skills, we don’t recommend trying it.

How do you know it’s time to replace your windows?

Windows typically have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have them looked at by an expert to see if they are in need of a repair or replacement.
