How Installing Energy-Efficient Windows in California Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to make the switch:

  • Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 467 pounds per year on average.
  • Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
  • More efficient energy usage in your household: In California where the winters can be very cold, energy-efficient windows reduce how much heat is lost through your windows, making it easier to keep your home warm.
  • Better temperature control in your home: When you live in a place like California where the summers can get quite hot, you usually need to rely on your air conditioner to keep your home cool. Energy-efficient windows can lower how hard your AC needs to work to cool your home.

Estimated Cost of Window Replacement in California

Let's take a look at the cost of window replacement and the types of services you may need for your home.

How Much Do New Windows Cost?

Typically, homeowners in California can anticipate that most replacement window installations will range from $250 to $1,200, with the average cost sitting at about $600. This is because window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.

It's also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star predicts that upgrading the windows on your California 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. The amount of money you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

We advise requesting free quotes from several window installers to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

When it comes to window replacements, in general there are two types that your installer will have: full-frame and pocket installations.

A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.

If you're unsure which window installation service you need, your installer can advise you. In general, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in California

In our search to find the most reliable, eco-friendly window installers in California, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. We've decided to evaluate the top window installers in California mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve California 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 on this list to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have positive things to say about their service from a certain installer, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. Still, we want to make sure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a considerable investment, so you'll want to be certain that investment is well protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installation companies 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.

California, PA Window Replacement FAQs

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

The national average cost of installing one window is about $600 but can range from $200 to $1,200, based on several factors. The price is generally influenced by the type and material of the window, the location of your property and the size of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What type of window is the most energy-efficient?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll have 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.

What do window installers do?

Window installation professionals go to your property to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

How long does it typically take to install windows?

Since a window takes about 30 minutes to install, around 16 windows can be installed in an 8-hour work day.
