Calabasas Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Calabasas, CA using our customized window cost calculator.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

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 upgrade to energy-efficient windows.
  • Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Installing energy-efficient windows can help lower that number, which helps you save $509 a year on your bills.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Calabasas

Each window installation company offers various services and has varying costs depending on several factors.

How Much Do New Windows Cost?

According to our research, the national average cost of replacing a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. This is due to the fact that window installations are based on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.

Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $509 a year on your energy bills in Calabasas.

Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

In regard to window replacements, in general there are two types that your provider will have: full-frame and pocket installations.

Full-frame installations entail replacing the complete window, including the trim, sill and frame. Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. These installations are more involved and will raise overall costs. A pocket installation entails replacing a window without replacing the frame. So, instead of tearing out the whole window and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company should be able to help you decide what’s best for your needs. In Calabasas, the decision will mostly depend on the age of your windows and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Calabasas

EcoWatch reviews are different from other reviews, as we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve Calabasas so you can find a quality window installation company near you.

Work Quality

When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand you opt for. We do give window installers higher marks if they offer high-quality products, but we also consider 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 may be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, professionalism, cost, warranty, quality of installation 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 the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

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

Years of Experience

Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Calabasas, CA Window Replacement FAQs

What is the average cost to install windows?

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

What are the different kinds of windows?

There are several different types of windows you can get for your house, such as awning windows, picture windows, double-hung and single-hung windows, bay windows, casement windows, slider windows and transom windows.

Do I really need to use a window installation company?

You should hire a window installation professional whenever you want to replace your windows. Installing windows is a complex process that can be difficult and time-consuming, so it’s best left to the professionals.

Should I replace all my windows at the same time?

If you want to get more efficient windows and save money on your energy bills, replacing all of the windows at the same time is the only way to gain that benefit. On the other hand, if you have only a few windows that are broken or drafty, you can replace just those.

How long does it take to install windows?

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