How Installing Energy-Efficient Windows in Fillmore Saves You Money

By switching to energy-efficient windows, you can take advantage of several benefits, such as:

  • 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 Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
  • More efficient energy usage in your household: Because the winters can get very chilly in Fillmore, homeowners usually depend on their heater during that time. Energy-efficient windows lower the amount of heat that is lost through your windows, making it easier to keep your house warm.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Replacing your windows with energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Fillmore

Windows come in all shapes and sizes, so costs and services will differ remarkably. Here are the average costs and the primary services that you'll find from the average window installation company.

How Much Do New Windows Cost?

Generally, homeowners in Fillmore can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which have a higher price tag.

It's also worth keeping in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts 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 a year for double-pane windows. How much you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material you pick for your window frames. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

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

Full-frame installations entail replacing the total window, including the sill, frame and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable damage or rot. Because full-frame installations are more involved, they will increase overall costs. A pocket installation entails installing a new window within the existing frame. So, instead of taking out the whole window and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installer should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Fillmore

The EcoWatch Reviews team is different from other reviewers since we look at these companies through a sustainability lens. We've assessed the best window installers in Fillmore mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can lower electricity 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 Fillmore, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Fillmore.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each company included on this list to ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including cost, professionalism, quality of installation, warranty, quality of parts and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor 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 experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Fillmore, CA Window Replacement FAQs

What is the typical cost to install windows in a home?

The national average cost of replacing one window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is generally dependent on the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What type of window is the best for energy efficiency?

A window's energy efficiency is affected by several factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.

How long does window installation typically take?
