Why you can trust EcoWatch
A guide on the best window replacement companies in Isla Vista may not seem like the most riveting article on EcoWatch, but trust us, windows impact your life more than you might realize. The Department of Energy estimates that heat or cool air lost through old or damaged windows could represent close to 30% of residential energy climate use. In Isla Vista, where the electricity bills are an average of $30 per month, that’s almost $$108 per year wasted.
That’s also bad news for the environment because the additional energy required by outdated windows increases your carbon footprint.
We’ve compiled a guide on the top installation companies to help you in your search, so you can not only enjoy brand-new windows, but also save money on your electric bills.

How Installing Energy-Efficient Windows in Isla Vista Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to think about making the switch:
- Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of household energy use. Installing energy-efficient windows can help decrease that amount, which helps you save $482 a year on your bills.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Isla Vista, that’s about 117 pounds per year on average.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way.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.
Estimated Cost of Window Replacement in Isla Vista
Let’s take a look at the cost of installing new windows and the types of services you may need for your home.
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. These numbers vary based on specific characteristics of your installation, like material, size, type, the location of your home, number of windows and more.
It’s also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star predicts that upgrading the windows on your Isla Vista home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We advise requesting free quotes from several window companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first question to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?
Full-frame installations entail replacing the full window, including the trim, sill and frame. You most likely need a full-frame installation when you want a new style or your window has considerable deterioration. Because these installations are more involved, they will raise overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.
If you’re unsure which kind of window installation service you should get, your installer should be able to assist you. Typically, the choice is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Isla Vista
In our search to make your home improvements easier and more eco-friendly in Isla Vista, the EcoWatch Reviews team assessed many companies before landing on these. We’ve assessed the top window installers in Isla Vista mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve Isla Vista so you can find the best window installation company near you.
Work Quality
When installing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns 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 installation, professionalism, warranty, cost, quality of parts and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies won’t always provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) 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 installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
