Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home’s efficiency can also have a big impact on home energy conservation. According to the Department of Energy, heat gained or lost through traditional, outdated windows could be responsible for 25-30% of household energy climate control use.
That’s also bad news for the environment, as the extra energy required by leaky windows increases your carbon footprint.
Efficient windows are particularly important in Grand Terrace, where summers are long and hot. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $540 each year.

How Installing Energy-Efficient Windows in Grand Terrace Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to consider making the switch:
- Reduce your carbon footprint: By using less energy once you upgrade to energy-efficient windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Save on energy bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, the switch can help you save about $540 annually on your energy bills in Grand Terrace.
- 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 Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
- 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.
Estimated Cost of Window Replacement in Grand Terrace
When researching window installation, each company provides different services and costs. Let’s take a look at some typical costs and services.
How Much Do New Windows Cost?
Although the national average cost of installing a single window is around $600, it can range anywhere from $200 to $1,200. How much it will cost depends on several factors, like material, type, size, number of windows, the location of your home and more.
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 per year when replacing single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.
We advise requesting free quotes from multiple window installation companies to find the one that works best for your budget.
What Services do Window Installers Offer?
The first step of a replacement is to figure out whether you want a full-frame or pocket installation.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of damage. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation involves replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.
Your window installation company will be able to help you decide what’s best for your needs. In Grand Terrace, the decision will mostly be based on how old your windows are and if there’s any moisture damage. Wood can decay if it’s not maintained properly over the years, so it’s good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Grand Terrace
In our hunt to make your home improvements easier and more eco-friendly in Grand Terrace, EcoWatch assessed many companies before landing on these. We’ve evaluated the top window installation companies in Grand Terrace mainly 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 cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Grand Terrace, we gave more points to companies that serve the city. There are certainly other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Grand Terrace.
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 company included in our guide to make sure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have nice feedback 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 most services, cheap window installation companies may not provide the most quality service. Still, 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
As discussed, windows are a sizable investment, so you’ll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. 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.
Grand Terrace, CA Window Replacement FAQs
How much should window installation cost?
The national average cost to replace a window is around $600 but can range from $200 to $1,200, based on a few different factors. The price is typically influenced by the location of your property, the size of the window and the type and material 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.
Which kind of window should I get?
A window’s energy efficiency is influenced by several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
Do I really need to use a window installation company?
Unless you’re handy and have the time to replace your own windows, we recommend hiring the pros. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it’s tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer alternative.
What time of year is the best time to replace my windows?
Although you can install windows any time of year, warmer weather is typically better for replacing windows. Additionally, it shouldn’t be raining, since rain can make the installation more difficult.
How do you know it’s time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
