How Installing Energy-Efficient Windows in Thermalito Saves You Money
By switching to energy-efficient windows, you can take advantage of several benefits, such as:
- Reduce your carbon footprint: By using less energy after switching to energy-efficient windows, you'll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on power bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that amount, which helps you save $518 a year on your bills.
- Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Thermalito
Let's take a look at the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Though the average to install a single window is around $600, it can range anywhere from $200 to $1,200. These estimates vary depending on specific characteristics of your installation, including number of windows, material, size, type, the location of your home and more.
With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly 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 Thermalito homeowners $518+ per year after replacing single-pane windows.
Costs will also vary based on the material you choose for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat 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?
In regard to window replacements, there are typically two kinds that your provider will offer: full-frame and pocket installations.
Full-frame installations entail replacing the full window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has considerable damage or rot. Full-frame installations are more involved and will increase overall costs. A pocket installation involves installing a new window without replacing the frame. This means instead of tearing out the whole unit and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company should be able to help you understand what's best for your needs. In Thermalito, the decision will mostly depend on how old your home is and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional check on your frames and window sills.

Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area

Thermalito, CA Window Replacement FAQs
What is the average cost to install new windows?
The national average cost of replacing a window is around $600 but can range from $200 to $1,200, based on several factors. The price is typically dependent on the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What type of window is the most energy-efficient?
A window's energy efficiency depends on several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
What do window installation companies do?
Window installation professionals cover the entire process — from replacing old windows with brand new ones to cleaning up after the installation. In addition, a lot of companies offer window manufacturing, customization and repairs.
How often do you need to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
Should I replace my windows all at once?
If you want to get more efficient windows and save money on your energy bills, replacing all the windows together is the only way to gain that benefit. On the other hand, if you have just one or two windows that are broken or leaky, you can replace just those.
