How Installing Energy-Efficient Windows in Mill Valley Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Decrease your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Mill Valley
Windows come in varying shapes, styles and purposes, so costs and services will vary greatly depending on your project. Below, we detail the average cost and services that you can get from window installers.
How Much Do New Windows Cost?
The typical cost to install one window is about $600 but can range anywhere from $200 to $1,200. But costs will differ considerably depending on the current condition of your home, the number of windows you need, your location and the quality of your products. Many window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.
It’s important to keep in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Mill Valley homeowners $451+ a year when replacing single-pane windows.
Requesting free quotes from multiple installers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
The first question to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the full window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which raise the overall cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and won’t cost as much, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company should be able to help you understand what’s best for your needs. In Mill Valley, the decision will mostly be based on how old your windows are and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Mill Valley
EcoWatch reviews differ from other reviews because we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Mill Valley and ranked them based on the following methodology:
Service Area
Because this is a guide for Mill Valley, we only included companies that provide services to the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Mill Valley.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you get. 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 consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including quality of installation, professionalism, quality of parts, cost, warranty and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies won’t always provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a spectrum 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 with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Mill Valley’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Mill Valley window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Mill Valley, CA Window Replacement FAQs
What is the average cost to install windows in a home?
The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is usually dependent on the location of your property, the type and material of the window 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 are the most common kinds of replacement windows?
The most common types of windows for homes include: slider windows, picture windows, double-hung and single-hung windows, transom windows, awning windows, casement windows and bay windows.
Can I replace my own windows?
Although it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
Should I replace my windows all at the same time?
If you’re upgrading your windows to save on your energy bills, replacing all of the windows at once is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are damaged or leaky, you can replace just those.
How long does window installation usually take?
Since the average installation time of a window is 30 minutes, around 16 windows can be installed during an 8-hour work day.
