How Installing Energy-Efficient Windows in South San Francisco Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more ways switching out your windows could help you:

  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of household energy use. Installing energy-efficient windows can help reduce that number, which helps you save $652 a year on your bills.
  • Reduce your carbon footprint: In South San Francisco, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year after you upgrade to energy-efficient windows.

Estimated Cost of Window Replacement in South San Francisco

Let's go over the cost of window installation and the types of services you may need for your home.

How Much Do New Windows Cost?

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

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save South San Francisco homeowners $652+ a year after replacing single-pane windows.

How much your window installation costs will also vary based on the kind of window material you choose for the frames. Wood windows are generally the most expensive, but it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?

A full-frame installation is a replacement of the full window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, like insulation and drip edges, which raise the overall cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won't cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.

Your window installation company will be able to advise you on the best type for your project. In South San Francisco, the choice will mostly be influenced by the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in South San Francisco

EcoWatch reviews differ from most reviews since we're examining these companies through a sustainability lens. We have reviewed the best window installers in South San Francisco mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for South San Francisco, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in South San Francisco.

Work Quality

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

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, warranty, professionalism, cost, quality of parts and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies may not provide the most quality service. On the other hand, we want to make sure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies that give you 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 good track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

South San Francisco, CA Window Replacement FAQs

What is the average cost to replace windows in a home?

The typical cost of installing one window can range between $450 and $650. There are several factors that affect how much it costs, such as your property's location, local labor costs, how energy-efficient the windows are, the number of windows, styles and sizes of windows and the materials used in designing the windows.
