How Installing Energy-Efficient Windows in Castaic Saves You Money
By switching to energy-efficient windows, you can enjoy several benefits, including:
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that amount, which helps you save some money on your bills.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Castaic, that's about 117 pounds per year on average.
Estimated Cost of Window Replacement in Castaic
Windows come in different purposes, shapes and styles, so costs and services will vary remarkably depending on your project. Below, we describe the typical cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. But costs will vary significantly depending on the current condition of your home, the number of windows you need, the quality of your products and your location. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Something else that affects the total cost is the material you choose for your frame. Aluminum frames are typically the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step when planning an installation is to clarify whether you should get a full-frame or pocket installation.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations are on the simpler end and won't carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.
If you're still trying to decide which kind of installation you should get, you can ask your provider and get their advice. 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
In our hunt to find the most reliable, eco-friendly window installers in Castaic, EcoWatch landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed 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 serve the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Castaic.
Work Quality
When choosing 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 choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have nice things to say about their experience with a certain installer, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, we gave higher scores 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 well protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Castaic's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Castaic window companies to prepare homes for the climate. 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 of replacing a single window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is usually influenced by the size of the window, the type and material of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What kind of window is the best for energy efficiency?
A window's energy efficiency is influenced by a number of factors, such as 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 since they are certified by the U.S. Department of Energy.
Can I replace my own windows?
While it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help guarantee that the job is done properly and that you won't have to spend the time and effort to do it yourself.
Should I replace my windows all at once?
If you're upgrading your windows to save on your energy bills, replacing all of the windows at once is the only way to gain that benefit. However, if you have just a few windows that are broken or drafty, you can replace just those.
