Calculate how much you can expect to pay for window installation and replacement in Calabasas, CA using our customized window cost calculator.
Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.
How Installing Energy-Efficient Windows in Calabasas Saves You Money
By upgrading to energy-efficient windows, you can benefit in several ways, including:
- Reduce your carbon footprint: In Calabasas, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year after you switch to energy-efficient windows.
- Save money on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of household energy use. Switching to energy-efficient windows can help lower that amount, which helps you save some money on your bills.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
Estimated Cost of Window Replacement in Calabasas
Each window replacement company offers varying services and has varying prices based on a few factors.
How Much Do New Windows Cost?
Generally, homeowners in Calabasas can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. This is due to the fact that the cost of window installations depend on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.
With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Calabasas homeowners $509+ per year after replacing single-pane windows.
Getting free quotes from several providers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
There are generally two kinds of window replacement services: full-frame and pocket installations.
A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations are on the simpler end and won’t carry as large a bill, as they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.
If you’re unsure which window installation service you need, your installer can help you out. Typically, the choice is influenced by 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 Calabasas
In our search to find the most reliable, eco-friendly window installers in Calabasas, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. We have assessed the best window installation companies in Calabasas mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best 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 in our guide to ensure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good feedback about their service from a certain company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers may not provide the most quality service. Still, we want to ensure we’re highlighting companies that offer 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 protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Calabasas’s climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Calabasas window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
