20 Best Window Companies in Fillmore, CA (2025 Reviews)

How Installing Energy-Efficient Windows in Fillmore Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to take the plunge and make the switch:

• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
• Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of household energy use. Switching to energy-efficient windows can help lower that amount, which helps you save more on your bills.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Fillmore

When researching window installation, each company provides different services and prices. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

Typically, Fillmore homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at around $600. Costs will vary considerably depending on your location, the current condition of your home, the quality of your products and the number of windows you need. A lot of window companies also offer door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.

It’s also worth keeping in mind that energy-efficient windows will almost always cost more upfront, but Energy Star estimates that switching out the windows on your Fillmore home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

What Services do Window Installers Offer?

In regard to window replacements, there are generally two types that your provider will offer: full-frame and pocket installations.

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation involves replacing a window within the frame that’s already there. This means instead of removing the whole window and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company will be able to help you figure out what’s best for your needs. In Fillmore, the decision will mostly be based on how old your home is and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Fillmore

The EcoWatch Reviews team differs from most reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve Fillmore so you can find a quality window installation company near you.

Work Quality

When choosing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have good feedback about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window companies are not going to provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that provide a variety 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 provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Fillmore’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Fillmore window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
