How Installing Energy-Efficient Windows in Los Gatos Saves You Money
There are several perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Save on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of residential energy use. Switching to energy-efficient windows can help decrease that number, which helps you save more on your bills.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Reduce your carbon footprint: In Los Gatos, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year after you switch to energy-efficient windows.
Estimated Cost of Window Replacement in Los Gatos
Let’s take a look at the cost of replacing your windows and the types of services offered by installers.
How Much Do New Windows Cost?
Even though the national average cost of installing a single window is about $600, it can range from $200 to $1,200. How much it will cost depends on several factors, such as number of windows, size, the location of your home, type, material and more.
It’s important to bear in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Los Gatos homeowners $562+ a year when replacing single-pane windows.
Another factor that influences the overall cost is the material of the frame you choose. Aluminum frames are usually the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
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 is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which raise the overall cost of the project. It’s also worth noting that you may 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 existing 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.
If you’re unsure which kind of window installation service you should get, your installer can help you out. Typically, the choice depends on 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 Los Gatos
In our search to find the most reliable, eco-friendly window installers in Los Gatos, the EcoWatch Reviews team evaluated many companies before settling on these. We’ve evaluated the best window replacement companies in Los Gatos mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.
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 company in our guide to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have nice things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, 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 Gatos’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Los Gatos window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Los Gatos, CA Window Replacement FAQs
What is the typical cost to install windows in a home?
The national average cost to install a single window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is usually dependent on the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the most common types of replacement windows?
The most common kinds of windows for homes are casement windows, picture windows, transom windows, double-hung and single-hung windows, slider windows, bay windows and awning windows.
Can you replace your own windows?
While it is possible to install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help guarantee that the installation is done properly and that you won’t have to spend the time and effort to do it yourself.
How long does window installation usually take?
Each window takes about 30 minutes to install based on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
