How Installing Energy-Efficient Windows in Simi Valley Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could benefit you:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
- Save on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that number, which helps you save more on your bills.
Estimated Cost of Window Replacement in Simi Valley
Windows come in varying shapes, styles and purposes, so costs and services will vary greatly based on several factors. Below, we describe the average cost and services that you’ll find from window replacement companies.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. These amounts vary depending on specific characteristics of your installation, such as the location of your home, number of windows, type, material, size and more.
Whether or not you choose energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $572 a year on your energy bills in Simi Valley.
The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
When considering window replacements, there are generally two kinds that your provider will offer: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve additional 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 entails replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.
If you’re still debating which type of installation you need, you can talk to your provider and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Simi Valley
EcoWatch reviews are different from other reviews since we examine these companies through a sustainability lens. We’ve decided to review the top window installation companies in Simi Valley mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your 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 Simi Valley, we gave more points to companies that cover the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Simi Valley.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer included in our guide to ensure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to determine 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 indicates the quality of services across nearly every category, including cost, warranty, professionalism, quality of installation, quality of parts and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a considerable investment, so you’ll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Simi Valley’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Simi Valley window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Simi Valley, CA Window Replacement FAQs
What is the typical cost to install windows?
The typical cost of installing a window can range between $450 and $650. There are many factors that influence how much it costs, which include the number of windows, local labor costs, how energy-efficient the windows are, your property’s location, the materials used in designing the windows and styles and sizes of windows.
Which type of window should I get?
A window’s energy efficiency is influenced by several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
What do window installers do?
Window installation professionals travel to your home to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the house, so the temperature outside doesn’t necessarily matter that much. What’s most important is that the weather should be dry.
