San Francisco, CA Historic Property Preservation
Careful Restoration of Jackson Square, Post-1906 Terra Cotta Landmarks and San Francisco’s Historic Buildings
Historic Building Restoration Specialists in San Francisco, CA
Much of San Francisco’s historic core dates from two eras. A handful of Gold Rush brick buildings in Jackson Square survived the 1906 earthquake and fire, and the rebuilding that followed produced the terra cotta and stone-clad office buildings, hotels and civic landmarks that still define downtown. The Ferry Building opened in 1898, the rebuilt Palace Hotel in 1909 and the Beaux-Arts City Hall in 1915. These buildings face constant moisture from fog and rain, salt air near the bay and the ongoing stress of seismic activity.
Older buildings need repairs that respect how they were built. Mortar must stay softer than historic brick, terra cotta needs compatible repair and anchor replacement, and cleaning must not damage soft surfaces. Presto Restoration bases every historic scope on the National Park Service’s Preservation Briefs and works with your architect and engineer when a project needs review by the San Francisco Historic Preservation Commission or the California Office of Historic Preservation.
With more than 25 years of experience, our crews repoint brick with matched lime mortars, repair and re-anchor terra cotta, restore granite, sandstone and cast stone, repair historic windows and ironwork and apply breathable treatments that protect older walls.
OUR HISTORIC PRESERVATION SERVICES IN SAN FRANCISCO
From Gold Rush brick in Jackson Square to terra cotta towers and Beaux-Arts landmarks, Presto preserves San Francisco’s historic buildings with materials suited to how they were built.
San Francisco’s oldest brick was laid in soft lime mortar, and decades of fog and rain wear it away. Hard cement repairs often crack the brick around them. We remove failing joints carefully and repoint with lime mortar matched in strength, color and profile, and coordinate with any seismic strengthening your engineer has planned.
Glazed terra cotta covers many of the buildings put up after 1906, often over steel anchors that rust in San Francisco’s damp air. As anchors corrode, units crack and loosen. We inspect, replace corroded anchors, patch or replace damaged pieces, repair granite and sandstone and clean every surface gently.
Original wood and steel windows and bays are part of what makes historic San Francisco buildings distinctive. We repair and refinish frames, re-glaze with fresh compound and seal perimeters so the windows stay in service and keep wind-driven rain out.
Cornices, parapets, brackets and carved ornament are the most exposed parts of a building and often the first to fail, which can be a safety concern on busy sidewalks. We secure loose elements, repair damaged pieces and recreate missing details to match.
Cast iron storefronts, fire escapes, iron balconies and decorative railings are common on San Francisco’s older buildings, and salt air is hard on them. We clean and restore historic metals, stop corrosion, apply protective finishes and reseal the joints where metal meets masonry.
Historic masonry needs to release moisture, and San Francisco walls take on a lot of it. Sealing the face of an old wall can trap water inside, so we fix the real leak sources first and use breathable treatments only where they help.
Our Historic Preservation Process in San Francisco

San Francisco Historic Preservation FAQs
What makes historic preservation different from regular restoration?
Regular restoration makes a building sound and watertight. Preservation also protects original materials and details, using matched mortars, compatible terra cotta and stone repairs, gentle cleaning and repair instead of replacement.
Why does matched mortar matter on older San Francisco buildings?
Historic brick here was laid in soft lime mortar. Hard cement mortar traps moisture and does not flex with the wall, which cracks and spalls the brick around it.
Can an older building be made watertight without losing its character?
Yes. Most leaks come from eroded mortar, cracked terra cotta, failed flashings and worn window seals, and all of them can be repaired with compatible materials.
How long does a historic restoration project take?
A small building may take a few weeks, while a large terra cotta tower or civic landmark can take many months, depending on scope and review.
Does Presto work on designated historic properties in San Francisco?
Yes. For buildings that need review by the San Francisco Historic Preservation Commission or the California Office of Historic Preservation, we provide the scope and material information required.
How do you work with architects, engineers and preservation reviewers?
We share survey findings, material testing and proposed methods early, coordinate with any seismic work your engineer has planned and document the project with photos.
Does Presto follow National Park Service guidelines?
Yes. The National Park Service Preservation Briefs guide our methods for repointing, terra cotta repair, masonry cleaning and historic windows.
