How Installing Energy-Efficient Windows in Agoura Hills Saves You Money
When you switch to energy-efficient windows, you may see a few perks, including:
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 117 pounds.
- Save on power bills: Installing energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Protect your investment: If your home is on the older side, your windows are most likely outdated.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 property if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Agoura Hills
Let's take a look at the cost of window installation and the types of services you may need for your home.
How Much Do New Windows Cost?
Typically, Agoura Hills homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at about $600. How much it will cost you depends on several factors, like type, material, size, number of windows, the location of your home and more.
With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — especially 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 Agoura Hills homeowners $509+ each year after replacing single-pane windows.
We recommend getting free quotes from multiple window companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
Generally, there are two kinds of window installation services companies provide: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which raise the overall cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Agoura Hills
The EcoWatch Reviews team is different from most reviewers, as we're examining these companies through a sustainability lens. We have evaluated the best window installers in Agoura Hills mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Agoura Hills, we paid more attention to companies that cover the city. There are other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Agoura Hills.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each company in our guide to ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, warranty, quality of installation, cost, quality of parts and more.
Cost
This one is a give-and-take: as with other services, cheap window companies may not provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you'll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Agoura Hills, CA Window Replacement FAQs
How much does window installation cost?
The national average cost to replace a window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the kinds of windows?
The most common types of windows for homes are slider windows, casement windows, transom windows, bay windows, picture windows, awning windows and double-hung and single-hung windows.
Can you install your own windows?
If you're handy and have experience with similar home improvement projects, you may be able to install your own windows. However, if you don't have the time or skills, we recommend hiring a professional.
How long does it take to install windows?
Because the average installation time of a window is 30 minutes, around 16 windows can be installed during an 8-hour work day.
How often do you need to replace windows?
Windows typically have a lifespan of about 20 to 30 years, but anytime you see damage on your windows, it's a good time to have them checked by an expert to determine if they are in need of a repair or replacement.
