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.
