How Installing Energy-Efficient Windows in San Jacinto Saves You Money
By upgrading to energy-efficient windows, you can take advantage of several benefits, such as:
- Reduce your carbon footprint: By using less energy after you switch to Energy Star certified windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient windows can help decrease that number, which helps you save some money on your bills.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
Estimated Cost of Window Replacement in San Jacinto
Let’s go over the cost of installing new windows and the kinds of services you may need for your home.
How Much Do New Windows Cost?
On average, homeowners in San Jacinto can anticipate that most window installations will range from $250 to $1,200, with the average cost sitting at about $600. But costs vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will make your project cost more.
With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save San Jacinto homeowners $556+ per year after replacing single-pane windows.
We recommend requesting free quotes from several window companies to find the one that works best for you.
What Services do Window Installers Offer?
The first thing to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?
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 raise the overall cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you’re not sure which kind of window installation service you need, your installer should be able to advise you. In general, the choice is influenced by 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 San Jacinto
The EcoWatch Reviews team differs from other reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve San Jacinto 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 installer included on this list to ensure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including quality of parts, professionalism, quality of installation, cost, warranty and more.
Cost
This one is a give-and-take: as with most services, cheap window installers won’t always provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a considerable investment, so you’ll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to San Jacinto’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of San Jacinto window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
San Jacinto, CA Window Replacement FAQs
How much does window installation cost?
The typical cost of installing one window can range from $450 to $650. There are many factors that affect how much it costs, such as how energy-efficient the windows are, the materials used in designing the windows, your property’s location, styles and sizes of windows, local labor costs and the number of windows.
What kind of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they’re certified energy-efficient by the U.S. Department of Energy.
When do I need to use a window installation company?
You should use a window installation professional whenever you want to replace your windows. Installing windows is a complicated process that can take a lot of time, so it’s best handled by the professionals.
Should I replace my windows all at the same time?
If you’re upgrading your windows because of energy-efficiency, replacing all the windows together is the only way to see a noticeable difference. However, if you have only a few windows that are damaged or leaky, you can replace just those.
How long does window installation typically take?
Since the average installation time of a window is 30 minutes, about 16 windows can be installed in an 8-hour work day.
