Best Window Installation Companies in California [2022 Review]


You’ve probably heard us EcoWatchers talking up promising renewables like wind and solar, but efficiency is still the name of the game when it comes to conserving energy. Most readers might not realize that windows are one of the most important pieces of the home-efficiency puzzle, which is why we’ve decided to review the best window installation companies in California. 

The Department of Energy estimates that heat gained or lost through traditional or outdated windows could account for close to 30% of residential energy climate costs. If you have an energy bill of $125 per month, that’s almost $500 per year wasted.1 Fortunately, saving you energy with upgraded windows also helps our goals of conserving energy and the resources it takes to produce it. 

So if you’re building, renovating or changing out old windows in California, you’ve found the best place to get started.

The locations across California are all independently owned, which gives you the benefit of working with your own local, independent business. However, this also means that the experience, quality and customer service of your installer will vary slightly depending on where you live. We wouldn’t expect too much variation in quality, however, as Window World is certified for quality and safety by several well-respected institutions, including the Environmental Protection Agency (EPA) and Energy Star.6

Window World makes an impact beyond its installations as well. It is a female-owned business, led by chairman and CEO Tammy Whitworth; it contributes to St. Jude Children’s Research Hospital and leads a military initiative to give back to America’s active military and veterans.

Window Installation Costs & Services

Window installations come in starkly different shapes, styles and purposes, so costs and services will vary considerably based on your project. Below are the main services that you’ll find from the average replacement window installation company.

Window Installation Services

The first step of an installation is to clarify whether you need a full-frame installation or a pocket installation. 

  • Full-frame installations entail replacing the full window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. Full-frame installations are more involved and will increase overall costs. 
  • Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t have any pre-existing rot or water damage.

If you’re hiring a reputable window installation company, your company will be able to advise you on the best choices for your project. In California, the decision will mostly depend on the efficiency of your home and how well your frames are insulated. Wood and other window materials can deteriorate if not properly maintained over the years, losing the airtight seal and, with it, inside air. 

Window Installation Costs

On average, homeowners in California can anticipate most replacement window installations to range from $250 to $1,200. The most common installations sit around $600, but costs will vary significantly depending on the number of windows you need, the quality of your products, your location and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. Additional services will increase overall project costs.

Costs will also vary based on the material of your frame. Here’s a quick look at the quality of common types:

  • Aluminum frames (least expensive): Sturdy, light and maintenance-free; poor insulation
  • Vinyl frames (somewhat expensive): Made of polyvinyl chloride (PVC) with ultraviolet light (UV) stabilizers; good insulation
  • Composite frames (moderately expensive): Made from wood fibers encased in plastic; good insulation
  • Wood frames (most expensive): Most in-demand, aesthetically pleasing; decent insulation

With windows, efficiency is the most important factor for most homeowners. High efficiency may cost more off the bat, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save California homeowners $125+ per year after replacing just a single pane.9

How We Chose the Best Window Installers in CA

In our search to find the most reliable, eco-friendly window installers in California, the EcoWatch Reviews team assessed dozens of companies before landing on these five. We analyzed each installer and assigned rankings based on the following methodology:

Service Areas

Since California is such a massive state, we gave more points to companies likely to offer services and showrooms across the whole state rather than just in a specific city. For example, there are certainly reputable providers in both Northern and Southern California that didn’t make our list because of the low odds that they would serve the average Californian. 

Quality of Services

When selecting new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand 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. 


Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services. However, we won’t cut corners on customer service or efficiency, and the best companies in California certainly won’t always be the cheapest. 


Southern California has a very hot, sunny climate with a lot of temperature variation between the night and day. And temperatures vary up the coast as well. These are the perfect conditions for energy-efficient windows that can regulate internal temperatures inside while warding off sunshine during peak hours. We factored in local experience to reflect the ability of California window companies to prepare homes for their climates. If a company has less than 10 years of experience, it loses points in this category.

Customer Satisfaction

We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, quality of installation, quality of parts, warranty, cost and more. 

FAQ: Window Installation

When should I use a window installation company?

Window installation companies should be used for new constructions, renovations and window repair due to rot or deterioration. Unless you have some experience as a general contractor, it’s best not to attempt to take on projects that are too involved, as lower-quality installations can lead to efficiency losses or damages to your frame.

What are the most common types of windows?

The most common types of window installations are either single-hung or double-hung. Most homeowners don’t need anything fancy — and these windows are simple, effective and durable windows that won’t break the bank. The most common type of window frame is vinyl, as it is affordable and provides excellent insulation. 

How much does window installation cost in California?

The average window installation will vary in California depending on the details of your project, the quality of your products and the number of windows you purchase. We’d expect the most basic window installations to start at around $250 per window. 

What window type is the most energy efficient?

Completely fixed windows are the most airtight and offer the highest levels of efficiency. If your home doesn’t allow for fixed windows (if you already have windows with frames installed), vinyl or composite windows will offer the most efficient insulation. 

How often do you need to replace windows?

We found that the average window needs replacement every 10-15 years. Standard window warranties will expire at around 15 years, sometimes reaching 20. This reflects how long the manufacturer expects the window to perform as advertised.
