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

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

• Decrease your carbon footprint: In San Francisco, you can cut your indirect greenhouse gas emissions by about 117 pounds per year after you upgrade to energy-efficient windows.
• Save on power bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save around $177 annually on your energy bills in San Francisco.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
• Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.

Estimated Cost of Window Replacement in San Francisco

When researching window installation, each company offers different services and prices. Let's look at some typical costs and services.

How Much Do New Windows Cost?

The typical cost to replace one window is about $600 but can range from $200 to $1,200. How much it will cost you depends on several factors, such as material, size, number of windows, the location of your home, type and more.

With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save San Francisco homeowners $177+ per year after replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services you can get: full-frame and pocket installations.

Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the entire window, including the trim, frame and sill. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won't carry as large a bill, but you can't do this type of installment if you have any pre-existing rot or water damage.

Your window installation company can help you figure out which type of installation you need.

How We Choose the Best Window Installers in San Francisco

EcoWatch reviews differ from other reviews since we evaluate these companies through a sustainability lens. We've assessed the top window installation companies in San Francisco primarily based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut 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 San Francisco, we paid more attention to companies that serve the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in San Francisco.

Work Quality

When installing new windows, the quality and breadth 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 give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

This one is a give-and-take: similar to most services, cheap window companies won't always provide the highest quality service. Still, we want to ensure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.

Warranty

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

Years of Experience

Due to San Francisco's climate, homeowners will want to mitigate water damage, rot and low efficiency. 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.
