How Installing Energy-Efficient Windows in Kentfield Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more ways switching out your windows could benefit you:
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Kentfield, that's about 117 pounds per year on average.
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Kentfield
Windows come in all shapes and sizes, so costs and services will vary greatly. Here are the average costs and services that you'll find from window installation companies.
How Much Do New Windows Cost?
Even though the national average to install one window is around $600, it can range anywhere from $200 to $1,200. But costs will vary considerably depending on the quality of your products, the number of windows you need, the current condition of your home and your location. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. These extra services will increase your overall project costs.
It's important to bear in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Kentfield homeowners $451+ a year when replacing single-pane windows.
Asking for free quotes from multiple companies is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
There are generally two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of damage. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails replacing a window without taking out the complete frame, which is usually cheaper than a full-frame installation.
If you're not sure which kind of window installation service you should get, your installer can advise you. Generally, the decision is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Kentfield
EcoWatch reviews differ from most reviews, as we evaluate these companies through a sustainability lens. We've assessed the top window replacement companies in Kentfield mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can lower energy 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 Kentfield, we gave more points to companies that provide services to the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Kentfield.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer included in our guide to make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, quality of parts, warranty, cost, quality of installation and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies are not going to provide the most quality service. Still, we want to ensure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Kentfield's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Kentfield window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Kentfield, CA Window Replacement FAQs
What is the typical cost to install windows?
The national average cost of replacing a single window is about $600 but can range from $200 to $1,200, based on several factors. The price is generally dependent on the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
Which type of window should I get?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
What do window installers do?
Window installation professionals visit your house to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation.
What time of year is the best time to replace my windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the home, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
How often do you need to replace your windows?
Windows usually last around 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have them checked by an expert to determine if they are in need of a repair or replacement.
