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

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

  • Protect your valuables from fading: When you switch 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 damaging UV rays.
  • Decrease your carbon footprint: By using less energy after switching to Energy Star certified windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
  • Save money on power bills: Once you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.

Estimated Cost of Window Replacement in South San Francisco

When looking into window installation, each company offers varying services and costs. Let’s look at some typical costs and services.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range from $200 to $1,200. But prices vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which have a higher price tag.

It’s also worth noting that energy-efficient windows will almost always cost more upfront, but Energy Star estimates that upgrading the windows on your South San Francisco home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Requesting free quotes from several providers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

In general, there are two types of window replacement services companies offer: full-frame and pocket installations.

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 also involves additional materials, like 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 surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

Your window installation company can advise you on the best type for your project. In South San Francisco, the decision will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in South San Francisco

In our search to make your home improvements easier and more eco-friendly in South San Francisco, EcoWatch evaluated dozens of companies before landing on these. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:

Service Area

Because this is a guide for South San Francisco, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn’t make the 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 a company to do a great job installing windows. We’ve vetted each installer included in our guide to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

This one is a give-and-take: as with other services, cheap window installers may not provide the most quality service. Still, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more 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 typical cost to replace windows in a home?

The average cost of installing one window can range from $450 to $650. There are many factors that affect how much it costs, including how energy-efficient the windows are, your property’s location, the number of windows, local labor costs, the materials used in designing the windows and styles and sizes of windows.

What kind of window is the best for energy efficiency?

Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. If you want to be sure you’re getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.

Can you replace your own windows?

Although it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

What time of year is the best time to replace my windows?

Replacement windows can be installed during any season, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your house, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.

Should I replace all my windows at once?

If your windows are more than 20 years old, it’s probably time to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
