How Installing Energy-Efficient Windows in Atascadero Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to consider making the switch:
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Atascadero, that's about 117 pounds per year on average.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
- Save on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
Estimated Cost of Window Replacement in Atascadero
When researching window installation, each company offers varying services and prices. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
Typically, homeowners in Atascadero can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. Costs will differ considerably 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 door installations and other add-ons like baths, shutters, coating and more. These extra services will increase your overall project costs.
Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $521 a year on your energy bills in Atascadero.
We advise requesting free quotes from multiple window installers to find the one that works best for you.
What Services do Window Installers Offer?
The first question to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?
A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. A pocket installation involves replacing a window within the existing frame. So, instead of tearing out the whole unit and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're not sure which window installation service you need, your installer can assist you. Generally, the choice is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Atascadero
EcoWatch differs from other reviewers since we look at these companies through a sustainability lens. We've decided to assess the top window installation companies in Atascadero mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Atascadero so you can find the best window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand 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
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good things to say about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when 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 hefty investment, so you'll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Atascadero's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Atascadero window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Atascadero, CA Window Replacement FAQs
What is the typical cost to install new windows in a home?
The national average cost of replacing a single window is around $600 but can range from $200 to $1,200, based on a few different factors. The price is often dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the most common kinds of replacement windows?
The most common types of windows for homes include: casement windows, slider windows, double-hung and single-hung windows, awning windows, bay windows, transom windows and picture windows.
What do window installation companies do?
Window installation companies cover the entire process — from replacing old windows with new ones to cleaning up after the windows have been put in place. Additionally, some companies offer window manufacturing, customization and repairs.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but autumn might be best. 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 home, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
How do you know it's time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
