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

By switching to energy-efficient windows, you and your family can take advantage of several benefits, including:

• Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of household energy use. Switching to energy-efficient windows can help decrease that number, which helps you save $556 a year on your bills.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.
• Reduce your carbon footprint: By using less energy once you upgrade to Energy Star certified windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in El Sobrante

Windows come in various styles, purposes and shapes, so costs and services will differ considerably based on your project. Below, we detail the typical cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

According to our research, the national average cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. These numbers are based on specific characteristics of your installation, like number of windows, size, type, material, the location of your home and more.

It’s also worth noting that energy-efficient windows will almost always cost more initially, but Energy Star estimates that switching out the windows on your El Sobrante home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

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

What Services do Window Installers Offer?

The first step when planning a window replacement is to decide whether you want a full-frame or pocket installation.

Full-frame installations involve replacing the full window, including the trim, sill and frame. You most likely need a full-frame installation when you want a new style or your window has noticeable damage or rot. These installations are more involved and will increase overall costs. A pocket installation means replacing a window without removing the whole frame, which is usually less expensive than a full-frame installation.

Your window installer should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in El Sobrante

EcoWatch differs from other reviewers because we evaluate these companies through a sustainability lens. We have reviewed the best window installers in El Sobrante primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

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

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company featured on this list to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have good feedback about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that offer 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 years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
