How Installing Energy-Efficient Windows in Los Altos Hills Saves You Money
When you switch to energy-efficient windows, you may see several perks, such as:
- Protect your valuables: Many energy-efficient 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.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Los Altos Hills, that's about 117 pounds per year on average.
- Save on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Installing energy-efficient windows can help reduce that number, which helps you save $562 a year on your bills.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
Estimated Cost of Window Replacement in Los Altos Hills
Windows come in varying styles, shapes and purposes, so costs and services will differ remarkably based 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 national average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. But costs will vary considerably based on the current condition of your home, the quality of your products, the number of windows you need and your location. A lot of window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase your overall project costs.
It's also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that upgrading the windows on your Los Altos Hills 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 depends on your local climate, energy rates and other factors unique to your home.
We recommend requesting free quotes from several window companies to find the one that works best for you.
What Services do Window Installers Offer?
In regard to window replacements, in general there are two types that your installer will have: full-frame and pocket installations.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations are more involved and will increase overall costs. 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 replacement company should be able to help you figure out what's best for your needs. In Los Altos Hills, 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 a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Los Altos Hills
In our hunt to make your home improvements easier and more eco-friendly in Los Altos Hills, the EcoWatch team landed on the above companies as the best window installation companies in the city. We have evaluated the best window installation companies in Los Altos Hills primarily based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Los Altos Hills so you can find the right window installation company near you.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each installer featured in our guide 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
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good feedback about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers may not provide the highest quality service. Still, we want to make sure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a substantial investment, so you'll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Los Altos Hills' climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Los Altos Hills window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Los Altos Hills, CA Window Replacement FAQs
How much should window installation cost?
The average cost to replace one window can range from $450 to $650. There are many factors that affect the cost, such as 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.
Which type of window should I get?
A window's energy efficiency is affected by a number of 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 since they are certified by the U.S. Department of Energy.
Can you replace your own windows?
If you're handy and have the time and patience to do the job right, it's possible to install your own windows. However, if you don't have the time or know-how, we recommend hiring a professional.
How long does it usually take to install windows?
Because the average installation time is 30 minutes per window, about 16 windows can be installed in an 8-hour work day.
Should I replace all my windows at the same time?
If you're upgrading your windows because of energy-efficiency, replacing all your windows together is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are damaged or drafty, you can replace just those.
