Why you can trust EcoWatch
Whether you're doing home renovations or have old windows, windows play a vital role in conserving your home's energy. Outdated windows can cost you in power bills. As a matter of fact, the Department of Energy estimates that 25-30% of your home's heat or cool air could be lost through your windows.
Replacement windows improve your home's insulation, not only making you and your family more comfortable during extreme temperatures, but also saving you money and helping the environment.
Unlike other review sites, EcoWatch ranks window replacement companies on energy efficiency while also factoring in cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in San Mateo Saves You Money
There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Decrease your carbon footprint: In San Mateo, you can lower your indirect greenhouse gas emissions by about 117 pounds per year after you install energy-efficient windows.
- Save money on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in San Mateo
Let's take a look at the cost of replacing your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Even though the average of installing a single window is around $600, it can range from $200 to $1,200. But costs will differ considerably depending on the quality of your products, your location, the number of windows you need and the current condition of your home. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.
With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save San Mateo homeowners $440+ a year after replacing single-pane windows.
We recommend getting free quotes from several window installers to find the one that works best for you.
What Services do Window Installers Offer?
In general, there are two types of window replacement services companies provide: full-frame and pocket installations.
A full-frame installation replaces the complete window, including the windowsill, frame, trim and the window panes. Because this kind of installation requires more time, it will cost more than a pocket installation. A pocket installation means replacing a window within the existing frame, which is generally less expensive than a full-frame installation.
Your window installation company can help you decide which type of installation you need.

How We Choose the Best Window Installers in San Mateo
EcoWatch reviews are different from other reviews since we evaluate these companies through a sustainability lens. We've decided to evaluate the best window installers in San Mateo mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for San Mateo, we only included companies that provide services to the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in San Mateo.
Work Quality
When selecting new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand 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 patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including cost, quality of installation, professionalism, warranty, 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 gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a serious investment, so you'll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
San Mateo, CA Window Replacement FAQs
How much should a window install cost?
The average cost of installing a single window ranges from $450 to $650. There are a variety of factors that affect the price, including your property's location, styles and sizes of windows, the materials used in designing the windows, how energy-efficient the windows are, the number of windows and local labor costs.
What kind of window is the best for energy efficiency?
A window's energy efficiency is influenced by a number of factors, such as 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 since they are certified by the U.S. Department of Energy.
Do you really need to use a window installation company?
You should hire a window installation professional whenever you need to upgrade your windows. Installing windows is a complicated process that can be difficult and time-consuming, so it's best left to the professionals.
How long does window installation typically take?
Because the average installation time of a window is 30 minutes, about 16 windows can be installed in an 8-hour work day.
How often do you need to replace windows?
Windows typically have a lifespan of about 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have an expert take a look at them to see if they need any repairs or replacements.
