Arched & Specialty Windows
San Francisco & the Peninsula

Made to the
exact shape

Specialty windows include arches, half-rounds, quarter-rounds, eyebrows, trapezoids, octagons and transoms. Most are fixed, though some arched units can open, and many sit above or beside a standard window as part of one composition.

Because old openings are rarely perfect, we take a precise template of each shape rather than relying on nominal sizes. That is what keeps the new frame tight to the old opening, without gaps filled with caulk.

Why homeowners
choose them

• Keeps the character that makes an older house distinctive
• Brings light into gables, stairwells and over doors
• Can be paired with double-hungs or casements below
• Matches original shapes on historic facades
• Available with grids to match the rest of the house

What to know
before you choose

• Custom made, so lead times are longer than standard windows
• Most shapes are fixed and don’t open
• Curved frames limit some material and color choices

Where specialty shapes fit
SF and Peninsula homes

• Arched windows on Italianate Victorians in the Western Addition, Alamo Square and the Mission
• Transoms over front doors and bay windows on Edwardians
• Half-rounds and quarter-rounds in Queen Anne gables
• Tudor and Mediterranean homes in San Mateo and Burlingame
• Stairwells and vaulted rooms in Peninsula homes

On historic facades the shape, the frame profile and the grid pattern all need to match the original. We document the existing window before removal so the replacement is right the first time.
