How Installing Energy-Efficient Windows in Castaic Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could benefit you:

  • 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
  • Reduce your carbon footprint: In Castaic, you can lower your indirect greenhouse gas emissions by about 117 pounds per year when you install energy-efficient windows.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
  • Save money on power bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll require less energy to heat or cool your house.

Estimated Cost of Window Replacement in Castaic

Windows come in varying styles, purposes and shapes, so costs and services will vary tremendously based on several factors. Below, we go over the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

According to our research, the national average cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost varies based on several factors, such as the location of your home, type, size, number of windows, material and more.

It’s important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Castaic homeowners $509+ a year when replacing single-pane windows.

Costs will also vary depending on the material you want for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your installers will replace the total window, including the trim, frame and sill. A pocket installation entails installing a new window without replacing the frame. This means instead of taking out the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re still trying to decide which type of installation you need, you can ask your provider and get their recommendation. The decision mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Castaic

EcoWatch reviews are different from other reviews because we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them based on the following methodology:

Service Area

Because this is a guide for Castaic, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Castaic.

Work Quality

When installing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type 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 super important review factor. If the majority of customers don’t have positive feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies may not provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide 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. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Castaic, CA Window Replacement FAQs

What is the average cost to replace windows in a home?

The national average cost to replace a single window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is usually dependent on the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the most common kinds of replacement windows?

There are various types of windows you can get for your home, such as casement windows, double-hung and single-hung windows, awning windows, slider windows, bay windows, picture windows and transom windows.

What do window installers do?

Window installers cover the entire process — from replacing your old windows with new ones to cleaning up afterward. In addition, a lot of companies offer window manufacturing, customization and repairs.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your house, so the temperature outside isn’t necessarily a big factor. Most importantly, the weather should be dry.
