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 energy bills. Here are more details about how upgrading your windows could benefit you:

• Save on energy bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll need less energy to heat or cool your home.
• Reduce your carbon footprint: In California, you can lower your indirect greenhouse gas emissions by about 763 pounds per year after 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 fade less because of their ability to filter out damaging UV rays.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in California

Windows come in various purposes, shapes and styles, so costs and services will differ greatly based on several factors. Below, we describe the typical cost and services that you'll find from window replacement companies.

How Much Do New Windows Cost?

On average, California homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at about $600. How much it will cost you varies based on several factors, like type, number of windows, the location of your home, material, size and more.

With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save California homeowners $386+ a year after replacing single-pane windows.

Another factor that affects the overall cost is the material you select for your frame. Aluminum frames are usually 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 because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well 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 other materials, such as insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation means replacing a window within the existing frame, which is generally cheaper than a full-frame installation.

Your window installation company will be able to help you choose what's best for your needs. In California, the decision will mostly depend on how old your windows are and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional check your frames and window sills.

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 reviewed the best window replacement companies in California mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve California so you can find the right window installation company near you.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each company featured in our guide to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews 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 quality of installation, quality of parts, professionalism, cost, warranty and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies won't always provide the most quality service. On the other hand, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a sizable investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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