How Installing Energy-Efficient Windows in East San Gabriel Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to think about making the switch:
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Save on electricity bills: After 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 house.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In East San Gabriel, that’s about 117 pounds per year on average.
Estimated Cost of Window Replacement in East San Gabriel
Let’s go over the cost of replacing your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Although the national average cost of replacing a single window is about $600, it can range anywhere from $200 to $1,200. These figures vary based on the specifics of your installation, like type, size, material, number of windows, the location of your home and more.
With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save East San Gabriel homeowners $509+ each year after replacing single-pane windows.
Requesting free quotes from multiple providers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
When it comes to window replacements, in general there are two kinds that your provider will have: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the complete window, including the sill, trim and frame. A pocket installation entails installing a new window without replacing the frame. This means instead of taking out the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installer can help you choose which type of installation you should get.

How We Choose the Best Window Installers in East San Gabriel
EcoWatch reviews differ from most reviews because we evaluate these companies through a sustainability lens. We’ve reviewed the best window installers in East San Gabriel mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for East San Gabriel, we paid more attention to companies that provide services to the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in East San Gabriel.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company featured on this list to ensure its technicians are well-qualified and that the company has received plenty 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 good things to say 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 other services, cheap window installation companies may not provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of East San Gabriel’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of East San Gabriel window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
East San Gabriel, CA Window Replacement FAQs
What is the typical cost to install windows in a home?
The average cost to install a single window ranges between $450 and $650. There are many factors that influence the cost, which include your property’s location, the materials used in designing the windows, the number of windows, local labor costs, styles and sizes of windows and how energy-efficient the windows are.
What are the different kinds of windows?
There are various kinds of windows you can get for your house, including picture windows, bay windows, double-hung and single-hung windows, awning windows, transom windows, slider windows and casement windows.
Can I replace my own windows?
If you’re handy and have experience with installing a replacement window, you may be able to install your own windows. But if you don’t have the time or experience, we recommend getting a professional to do it for you.
What time of year is the best time to replace my windows?
Though you can install windows any time of year, warmer weather is typically better for installing replacement windows. In addition, it shouldn’t be raining, since rain can make the installation more difficult.
Should I replace all my windows at once?
If you’re upgrading your windows to save on your energy bills, replacing all of the windows at the same time is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are broken or leaky, you can replace just those.
