Window Types
Double-hung, casement, and sliding-glass windows are common in San Francisco. Here at Best Exteriors, we replace a huge variety of window types for our clients:
Single-Hung Windows
Consider the style that started it all if you’re shopping for new windows. Single-hung windows have endured over time due to their simplicity and practicality. The classic functions of our window products make them easy to operate and maintain, and cost-effective.
Double-Hung Windows
Most American homes feature double-hung windows. They have two operable sashes that move vertically within the frame. Air can be circulated and ventilated more easily by raising or lowering it from the bottom or top. You can also easily clean the exterior of double-hung windows by tilting the sashes outward.
Casement Windows
These types of windows open outward with a hinged sash. The crank is used to open and close them. The entire panel of a hinged casement window opens for ventilation. The panels often act as wind catchers, directing breezes into a room based on their placement.
Sliding Window
Slide windows open horizontally with a single panel, providing significant natural light and fresh air into a home. Their versatility, durability, and scalability have kept them popular for years. For hard-to-reach areas with no extra space, this style is ideal. Large openings are particularly suited to this design.
Awning Windows
An awning window opens outward using a crank. As a functional alternative to a transom window, they are ideal for areas that are difficult to reach, including above a kitchen sink. If you are considering an awning window for a room that requires privacy (such as a bedroom or bathroom) while you still desire access to natural light, you are making a wise choice.
Bay Windows
A bay window is a set of three angled panels that protrude from a home’s exterior. Instead of extending from a wall in an angular manner, bow windows follow a curved path. Exterior walls at least 40 inches wide work best for them. A bay window captures significant natural light from multiple directions, which is why homeowners find its aesthetics appealing.
Bow Windows
Bow windows are rounded, roof-mounted casements arranged in a curved line along a home’s exterior. A bow window looks similar to a bay, except that it is curved, semi-circular in shape, instead of being square or rectangular, giving it a classic, elegant, and traditional appearance.
Four or five similar-sized panes are usually used for bow windows. The best place for a bow window is on an exterior wall or in a corner, with a minimum size of 80 inches. They create the impression of a larger, brighter room by extending beyond a residence’s exterior walls.
Custom Windows
Window styles can be tailored to fit a specific customer’s needs. Almost any size, shape, or design can be built to meet your specifications.

FAQs
Are builder-grade windows different from replacement windows?
Builder-grade windows are lower quality than replacement-grade windows because new-home builders and contractors aim to maximize their return on investment by buying the cheapest products they can find.
What is the recommended frequency for replacing home windows?
There is no set frequency. Modern windows are built to last for at least 30 years, if not longer. You replace your windows when they start to fall apart, or you want a change in style.
Approximately how long will it take to install windows?
Home window replacement in the San Francisco Bay Area takes 1-2 days. The time required to remove and install a window depends on its type. Most windows take about 30 minutes to remove and install. Trimming and cleaning may take a little longer.
Is it worth replacing 20-year-old windows?
Yes. Windows older than 20 years are likely not very energy-efficient and may not insulate your house correctly.
Do you get a tax write-off for new windows?
It depends. Some energy-efficient windows qualify for federal tax credits up to $600. California may offer extra rebates through utility programs. Consult your tax advisor.
