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

When you switch to energy-efficient windows, you may see some perks, such as:

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 117 pounds per year on average.
  • Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
  • Save on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in San Francisco

When researching window installation, each company provides varying services and costs. Let's look at some typical costs and services.

How Much Do New Windows Cost?

Generally, homeowners in San Francisco can anticipate that most window installations will range from $250 to $1,200, with the average cost sitting at around $600. This is because window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.

It's important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save San Francisco homeowners $613+ a year when replacing single-pane windows.

We advise requesting free quotes from multiple window companies to find the one that works best for you.

What Services do Window Installers Offer?

The first question to ask yourself when getting new windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations involve replacing the complete window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has noticeable deterioration. Because full-frame installations are more involved, they will raise the total cost. A pocket installation involves installing a new window within the old frame. This means instead of removing the whole window and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're hiring a reputable window installation company, your company can recommend the best type for your project. In San Francisco, the decision will mostly depend on how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in San Francisco

The EcoWatch Reviews team is different from other reviewers, as we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in San Francisco and assigned rankings based on the following methodology:

Service Area

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

Work Quality

When choosing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

This one is a give-and-take: similar to other services, cheap window installers won't always provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.

Warranty

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

Years of Experience

Because of San Francisco's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of San Francisco window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

San Francisco, CA Window Replacement FAQs

How much should a window install cost?

The national average cost to install a window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is usually influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What type of window is the most energy-efficient?

A window's energy efficiency is affected by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

Can I install my own windows?

If you're handy and have experience with similar home improvement projects, it's possible to install your own windows. But if you don't have the time or skills, we recommend getting a professional to do it for you.

How long does window installation usually take?

Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.

Should I replace my windows all at the same time?

If your windows are greater than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
