How Installing Energy-Efficient Windows in Atherton Saves You Money

By switching to energy-efficient windows, you and your family can benefit in several ways, including:

• Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 117 pounds per year on average.
• Save money on energy bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save around $440 annually on your energy bills in Atherton.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Atherton

Windows come in different shapes and sizes, so costs and services will differ tremendously. Here are the average costs and the primary services that you'll find from window installation companies.

How Much Do New Windows Cost?

Typically, homeowners in Atherton can expect that most replacement window installations will range from $250 to $1,200, with the average cost sitting at about $600. Costs will differ considerably depending on your location, the current condition of your home, the number of windows you need and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.

It's also worth bearing in mind that energy-efficient windows will usually cost more upfront, but Energy Star estimates that switching out the windows on your Atherton home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

What Services do Window Installers Offer?

The first thing to ask yourself when planning to replace your windows 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 and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.

Your window installation company will be able to help you choose what's best for your needs. In Atherton, the decision will mostly depend on how old your home is and if there's any moisture damage. Wood can decay if not maintained properly over the years, so it's a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Atherton

EcoWatch is different from most reviewers since we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Atherton and ranked them based on the following methodology:

Service Area

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

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each installer featured in our guide to ensure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, warranty, quality of parts, quality of installation, cost 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 the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

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

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
