How Installing Energy-Efficient Windows in California Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could benefit you:

  • Reduce your carbon footprint: By using less energy once switching to Energy Star certified windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
  • 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 increase the value of your house if you decide to sell.
  • Save money on electricity bills: Because energy-efficient windows reduce the amount of energy used to heat or cool your home, the switch can help you save about $232 annually on your energy bills in California.

Estimated Cost of Window Replacement in California

Windows come in different shapes and sizes, so costs and services will differ remarkably. Here are the average costs and services that you can find from the average window installation company.

How Much Do New Windows Cost?

Typically, homeowners in California can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. This is due to the fact that window installations depend on several factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.

It’s also worth noting that energy-efficient windows will almost always cost more initially, but Energy Star predicts that upgrading the windows on your California 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 varies based on your local climate, energy rates and other factors unique to your home.

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

What Services do Window Installers Offer?

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

Full-frame installations are usually done when you want a new style or your window has a lot of rot. With this service, your professionals will replace the complete window, including the frame, sill and trim. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re still debating which type of installation you need, you can consult with your provider and get their recommendation. The choice mostly is influenced by how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in California

EcoWatch reviews differ from most reviews because we’re examining these companies through a sustainability lens. We’ve assessed the top window replacement companies in California mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for California, we only included companies that serve the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in California.

Work Quality

When picking new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as 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. For that reason, window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of California’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of California window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

California, MD Window Replacement FAQs

How much does a window install cost?

The average cost to install a single window can range between $450 and $650. There are a variety of factors that influence the cost, including the number of windows, the materials used in designing the windows, how energy-efficient the windows are, local labor costs, your property’s location and styles and sizes of windows.

What are the most common types of replacement windows?

The most common kinds of windows for homes are transom windows, awning windows, casement windows, double-hung and single-hung windows, slider windows, bay windows and picture windows.

When should I use a window installation company?

Unless you have experience with home improvement projects and have the tools needed to replace your own windows, we recommend hiring a professional installer. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer alternative.

How long does window installation take?

Since the average installation time of a window is 30 minutes, around 16 windows can be installed in a typical 8-hour work day.
