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

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

  • Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that number, which helps you save $579 a year on your bills.
  • Decrease your carbon footprint: In El Cerrito, you can lower your indirect greenhouse gas emissions by about 117 pounds per year when you upgrade to energy-efficient windows.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in El Cerrito

Let's go over the cost of installing new windows and the types of services you may need for your home.

How Much Do New Windows Cost?

Typically, El Cerrito homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which have a higher price tag.

It's also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your El Cerrito 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. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

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

What Services do Window Installers Offer?

The first step when considering a window installation is to decide whether you should get a full-frame or pocket installation.

A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation entails replacing a window without taking out the complete frame, which tends to be cheaper than a full-frame installation.

If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In El Cerrito, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in El Cerrito

EcoWatch is different from other reviewers since we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:

Service Area

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

Work Quality

When installing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of parts, professionalism, cost, quality of installation, warranty and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the most quality service. Still, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That's why 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 years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

El Cerrito, CA Window Replacement FAQs

What is the average cost to replace windows in a home?

The typical cost of installing a single window can range between $450 and $650. There are many factors that affect the price, which include your property's location, styles and sizes of windows, local labor costs, how energy-efficient the windows are, the materials used in designing the windows and the number of windows.

What are the most common kinds of replacement windows?

There are several different types of windows you can get for your home, including double-hung and single-hung windows, awning windows, casement windows, bay windows, transom windows, picture windows and slider windows.

Do you really need to use a window installation company?

You should use a window installation professional whenever you need new windows. Installing windows is a complex process that can take a lot of time, so it's best handled by the professionals.

What time of year is a good time to replace my windows?

Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.

Should I replace my windows all at once?

If you want to get more efficient windows and save money on your energy bills, replacing all the windows together is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or drafty, you can replace just those.
