How Installing Energy-Efficient Windows in Atascadero Saves You Money
When you upgrade to energy-efficient windows, you may see a few benefits, such as:
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if you have an older home.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on electricity bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, they can help you save about $521 annually on your energy bills in Atascadero.
- More efficient energy usage in your household: In Atascadero where the winters can be very chilly, energy-efficient windows reduce how much heat is lost through your windows, making it easier to keep your house warm.
Estimated Cost of Window Replacement in Atascadero
Each window installer provides varying services and has varying costs based on several factors.
How Much Do New Windows Cost?
The national average cost to install one window is about $600 but can range from $200 to $1,200. This is because of the fact that the cost of window installations depend on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $521 a year on your energy bills in Atascadero.
Something else that affects the overall cost is the material of the frame you select. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first thing to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?
A full-frame installation is a total window replacement. This service involves removing the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're still trying to decide which type of installation you should get, you can ask your provider and get their advice. The choice mostly is influenced by the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Atascadero
In our search to find the most reliable, eco-friendly window installers in Atascadero, the EcoWatch team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated window companies all across the state and ranked them based on the following methodology:
Service Area
Since this is a guide for Atascadero, we only included companies that serve the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Atascadero.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. We do give window installers higher marks if they offer high-quality products, but we also consider 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 installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a significant investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
