Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house's energy efficiency can also have a considerable impact on home energy conservation.

Replacement windows improve the insulation in your home, not only making you more comfortable during extreme temperatures, but also saving you some money and helping the environment.

How Installing Energy-Efficient Windows in Fillmore Saves You Money
There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- Decrease your carbon footprint: In Fillmore, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year when you switch to energy-efficient windows.
- Save on power bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save around $498 annually on your energy bills in Fillmore.
- Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Fillmore
When looking into window installation, each company offers varying services and costs. Let's look at some average costs and services.
How Much Do New Windows Cost?
Even though the average to install a single window is about $600, it can range from $200 to $1,200. But prices differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which will add extra costs to your project.
It's important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Fillmore homeowners $498+ a year when replacing single-pane windows.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
The first thing to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the total window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which raise the overall cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation means replacing a window within the existing frame, which is usually cheaper than a full-frame installation.
If you're hiring a reputable window installation company, your company can recommend the best type for your project. In Fillmore, the decision will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Fillmore
EcoWatch reviews differ from most reviews, as we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:
Service Area
Since this is a guide for Fillmore, we only included companies that serve the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Fillmore.
Work Quality
When picking new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand 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 find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, professionalism, quality of installation, cost, quality of parts and more.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies won't always provide the highest quality service. Still, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a substantial investment, so you'll want to be certain that investment is well protected. Window installation companies that offer 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 been in the industry for a while. 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.
Fillmore, CA Window Replacement FAQs
How much should window installation cost?
The typical cost of installing a window can range from $450 to $650. There are several factors that affect the cost, including the number of windows, styles and sizes of windows, local labor costs, how energy-efficient the windows are, the materials used in designing the windows and your property's location.
Which type of window should I get?
A window's energy efficiency is affected by several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
What services do window installation companies do?
Window installation companies will do the entire process — from replacing old windows with brand new ones to cleaning up after the installation. Additionally, some companies offer window manufacturing, customization and repairs.
How long does it generally take to install windows?
Each window takes around 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
Should I replace all my windows at once?
If you're upgrading your windows to get more efficient windows, replacing all of the windows together is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are broken or leaky, you can replace just those.
