How Installing Energy-Efficient Windows in Austin Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more details about how switching out your windows could help you:

• Reduce your carbon footprint: In Austin, you can cut your indirect greenhouse gas emissions by about 507 pounds per year once you upgrade to energy-efficient windows.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Switching to energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Austin

Let’s go over the cost of window replacement and the types of services offered by installers.

How Much Do New Windows Cost?

On average, homeowners in Austin can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. These figures are based on the specifics of your installation, such as the location of your home, size, type, material, number of windows and more.

It’s also worth keeping in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts that switching out the windows on your Austin home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are completely 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 question to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are on the simpler end and won’t cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.

If you’re still trying to decide which type of installation you should get, you can ask your installer and get their advice. The choice mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Austin

EcoWatch reviews are different from other reviews because we look at these companies through a sustainability lens. We have assessed the best window installers in Austin mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Austin, we gave more points to companies that provide services to the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Austin.

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 type of window you choose. 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

We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, cost, quality of installation, warranty, professionalism and more.

Cost

Cheaper windows don’t necessarily 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

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
