How Installing Energy-Efficient Windows in Cupertino Saves You Money
By upgrading to energy-efficient windows, you can enjoy several benefits, including:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 117 pounds per year on average.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Save money on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
Estimated Cost of Window Replacement in Cupertino
Let's go over the cost of installing new windows and the kinds of services you may need for your home.
How Much Do New Windows Cost?
According to our market research, the average cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will make your project cost more.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more off the bat, 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 Cupertino homeowners $562+ per year after replacing single-pane windows.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation means replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
If you're still trying to decide which kind of installation you should get, you can talk to your installer and get their advice. The choice mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Cupertino
EcoWatch reviews are different from most reviews, as we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and ranked them using the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve Cupertino 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 installer on this list to make sure its contractors are well-qualified and that the company has received plenty 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. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including cost, warranty, quality of installation, professionalism, quality of parts and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that offer 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 quite some time. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Cupertino, CA Window Replacement FAQs
How much does a window install cost?
The typical cost to install a window can range from $450 to $650. There are several factors that affect how much it costs, including the number of windows, the materials used in designing the windows, styles and sizes of windows, your property's location, local labor costs and how energy-efficient the windows are.
What kind of window is the most energy-efficient?
A window's energy efficiency is influenced by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
What services do window installation companies offer?
Window installers go to your home to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
Should I replace my windows all at once?
If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
