Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home’s energy efficiency can also have a considerable impact on home energy conservation. During the hot summer months, the last thing you want is your cool air to leak out of your outdated, drafty windows.
Replacement windows improve your home’s insulation, not only making you more comfortable during extreme temperatures, but also saving you money and helping the environment.
Efficient windows are especially important in Glendale, where summers are long and hot. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $509 each year.

How Installing Energy-Efficient Windows in Glendale Saves You Money
There are quite a few perks of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by 117 pounds per year on average.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
- Save money on power bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your home.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Glendale
Each window installation company offers varying services and has varying prices based on a few factors.
How Much Do New Windows Cost?
On average, Glendale homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost is at about $600. Costs will vary considerably depending on the quality of your products, the current condition of your home, your location and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.
With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Glendale homeowners $509+ per year after replacing single-pane windows.
We advise getting free quotes from several window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
In general, there are two types of window installation services companies offer: full-frame and pocket installations.
A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will cost more than a pocket installation. Pocket installations (or retrofits) entail 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 installer should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Glendale
The EcoWatch Reviews team differs from other reviewers since we assess these companies through a sustainability lens. We have assessed the best window replacement companies in Glendale primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Glendale, we paid more attention to companies that serve the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Glendale.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer on this list to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including quality of installation, warranty, professionalism, quality of parts, cost and more.
Cost
Cheaper windows don’t necessarily 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 scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a significant investment, so you’ll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Glendale, CA Window Replacement FAQs
What is the typical cost to install new windows in a home?
The national average cost to install one window is about $600 but can range between $200 and $1,200, based on several factors. The price is often influenced by the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the most energy-efficient?
A window’s energy efficiency depends on a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
Can I replace my own windows?
If you’re handy and have experience with similar home improvement projects, it’s possible to install your own windows. However, if you don’t have the time or skills, we recommend hiring a professional.
How long does window installation usually take?
Each window takes about 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you have a lot of windows that need to be installed.
