How Installing Energy-Efficient Windows in San Marino Saves You Money
There are several benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- 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.
- Better temperature control in your home: When you live in a place like San Marino where the winters can be chilly, you usually need to rely on your heater to keep your house warm. Energy-efficient windows can reduce the amount of heat lost through your windows when heating your home.
- 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way.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.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In San Marino, that's about 117 pounds per year on average.
Estimated Cost of Window Replacement in San Marino
Let's go over the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. This is because of the fact that the cost of window installations are based on several factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.
Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.
Another factor that affects the total cost is the material you pick for your frame. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first thing to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations are necessary when you want to change the style of your windows or your window has significant deterioration. With this service, your installers will replace the total window, including the trim, frame and sill. A pocket installation entails installing a new window within the existing frame. This means instead of removing the whole window and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company can recommend the best type for your project. In San Marino, the decision will mostly be based on how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in San Marino
In our hunt to find the most reliable, eco-friendly window installers in San Marino, EcoWatch chose the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed each installer and ranked them based on the following methodology:
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 best window installation company near you.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included in our guide to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have nice feedback about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when 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 that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
San Marino, CA Window Replacement FAQs
What is the average cost to replace windows in a home?
The national average cost to replace one window is around $600 but can range from $200 to $1,200, based on several factors. The price is typically dependent on the location of your property, the size of the window and the type and material of the window. Also, keep in mind 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 kinds of windows?
The most common kinds of windows for homes include: awning windows, picture windows, slider windows, double-hung and single-hung windows, transom windows, casement windows and bay windows.
Can I replace my own windows?
If you're handy and know how to replace a window, you may be able to install your own windows. However, if you don't have the time or skills, we recommend hiring a professional.
How do you know it's time to replace your windows?
Windows usually have a lifespan of around 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have them checked by an expert to see if they need any repairs or replacements.
Should I replace all my windows at the same time?
If your windows are more than 20 years old, it's probably time to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
