Estimated Cost of Window Replacement in Atascadero

Each window installation company offers varying services and has varying price points depending on several factors.

How Much Do New Windows Cost?

According to our research, the average cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. This is because of the fact that window installations depend on several factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.

Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

How much your window installation costs will also vary based on the kind of window material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are solid 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?

The first step when planning an installation is to think about whether you need a full-frame or pocket installation.

A full-frame installation is a replacement of the full window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the total cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails installing a new window within the old frame. So, instead of tearing 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 debating which kind of installation to get, you can ask your installer 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 Atascadero

In our search to find the most reliable, eco-friendly window installers in Atascadero, EcoWatch assessed dozens of companies before landing on these. We have evaluated the best window replacement companies in Atascadero mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your power 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 the Atascadero area so you can find a quality window installation company near you.

Work Quality

When picking 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 get. We do give window installers more points 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 most customers don’t have positive feedback about their experience with a certain company, it won’t be featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a sizable investment, so you’ll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Atascadero’s climate, homeowners need to be wary of low efficiency, water damage and rot. 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.
