Why you can trust EcoWatch
Whether you're doing home renovations or have damaged windows, windows play a crucial role in conserving energy in your home. When it's the middle of summer, your outdated and drafty windows could be making your home more difficult to cool and costing you more in power bills.
That's also bad news for the environment because the additional energy required by drafty windows increases your carbon footprint.
Efficient windows are of particular importance in Larkspur, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $451 a year.

How Installing Energy-Efficient Windows in Larkspur Saves You Money
When you upgrade to energy-efficient windows, you may see several benefits, including:
- Reduce your carbon footprint: In Larkspur, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year after you upgrade to energy-efficient windows.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up 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 from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Larkspur
Let's take a look at the cost of updating your windows and the types of services offered by installers.
How Much Do New Windows Cost?
According to our research, the average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. Costs will differ significantly based on the quality of your products, the current condition of your home, the number of windows you need and your location. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. Additional services will increase your overall project costs.
It's also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star predicts that upgrading the windows on your Larkspur home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Costs will also vary based on the material you pick for your window frames. 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 with 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?
The first question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will cost more than a pocket installation. Pocket installations are simpler and won't cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company should be able to help you decide what's best for your needs. In Larkspur, the decision will mostly be based on how old your windows are and if there's any damage. Wood can decay if not properly maintained over the years, so it's good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Larkspur
EcoWatch reviews are different from most reviews because we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the Larkspur area so you can find the right window installation company near you.
Work Quality
When it comes to new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most 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 warranty, quality of installation, cost, 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 the prices of providers, 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. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Larkspur, CA Window Replacement FAQs
How much does a window install cost?
The average cost to install a window ranges from $450 to $650. There are several factors that influence the cost, which include your property's location, local labor costs, how energy-efficient the windows are, the number of windows, styles and sizes of windows and the materials used in designing the windows.
Which type of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies do?
Window installers visit your property 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.
How do you know it's time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
