Calculate how much you can expect to pay for window installation and replacement in San Carlos, CA using our customized window cost calculator.
Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.
How Installing Energy-Efficient Windows in San Carlos Saves You Money
Energy-efficient windows can offer benefits in more than one way. Here are some reasons you may want to make the switch:
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way.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 raise the value of your home if you decide to sell.
- More efficient energy use in your home: Because the winters can get very cold in San Carlos, homeowners usually depend on their heater a lot. Energy-efficient windows lower the amount of heat that is lost through your windows, which makes it easier to keep your home warm.
- Save on power bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you'll use less energy to heat or cool your home.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in San Carlos
Windows come in various shapes and sizes, so costs and services will vary remarkably. Here are the average costs and the primary services that you'll find from window installers.
How Much Do New Windows Cost?
Even though the national average to install one window is about $600, it can range anywhere from $200 to $1,200. How much it will cost is based on several factors, including number of windows, type, the location of your home, material, size and more.
Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $440 a year on your energy bills in San Carlos.
We recommend getting free quotes from multiple window companies to find the one that works best for you.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services companies offer: 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 additional materials, including insulation and drip edges, which increase the total cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installation company will be able to help you decide what's best for your needs. In San Carlos, the decision will mostly depend on how old your home is 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 assess your frames and window sills.

How We Choose the Best Window Installers in San Carlos
The EcoWatch Reviews team differs from other reviewers since we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the San Carlos area so you can find the best window installation company near you.
Work Quality
When it comes to 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 opt for. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good things to say about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as 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 with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of San Carlos' climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of San Carlos window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
