How Installing Energy-Efficient Windows in San Anselmo Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here's more information on how switching out your windows could benefit you:
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 117 pounds.
- Save on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that number, which helps you save $451 a year on your bills.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
Estimated Cost of Window Replacement in San Anselmo
Windows come in varying shapes, purposes and styles, so costs and services will vary considerably based on several factors. Below, we describe the typical cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
Although the typical to replace a single window is around $600, it can range from $200 to $1,200. But costs will vary significantly based on the current condition of your home, your location, the number of windows you need and the quality of your products. Many window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase overall project costs.
Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $451 a year on your energy bills in San Anselmo.
We recommend requesting free quotes from multiple window installers 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 replacement services you can get: full-frame and pocket installations.
A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installation company can help you decide which type of installation you should get.

How We Choose the Best Window Installers in San Anselmo
EcoWatch is different from most reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in San Anselmo and ranked them using the following methodology:
Service Area
Because this is a guide for San Anselmo, we gave more points to companies that cover the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in San Anselmo.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included on this list to ensure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of parts, professionalism, warranty, quality of installation, cost and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies won't always provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to San Anselmo's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of San Anselmo window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
San Anselmo, CA Window Replacement FAQs
What is the average cost to install windows?
The average cost to install one window ranges between $450 and $650. There are many factors that affect how much it costs, which include styles and sizes of windows, the materials used in designing the windows, how energy-efficient the windows are, local labor costs, your property's location and the number of windows.
What kind of window is the most energy-efficient?
A window's energy efficiency depends on several factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
What do window installers do?
Window installers cover the entire process — from replacing your old windows with new ones to cleaning up after the installation. In addition, some companies offer window manufacturing, customization and repairs.
Should I replace all my windows at once?
If your windows are more than 20 years old, it's most likely time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
