Concrete contractor in the Western Addition
The Western Addition holds one of the largest concentrations of Victorian houses in San Francisco, because the 1906 fire stopped at Van Ness Avenue. Decades later, redevelopment cleared thousands of homes in the Fillmore. Its concrete reflects both: century-old brick foundations under the survivors, and aging complexes where the old blocks used to be.

Survived the fire, then the bulldozer
Few San Francisco neighborhoods show their history this plainly in their buildings. It is also why a foundation check belongs on any Western Addition estimate.
⌂ West of Van Ness
In 1906, the fire was stopped at Van Ness Avenue. Everything west of that line, including the Western Addition, kept its Victorians, and many of those houses still sit on the brick foundations they were built with between the 1870s and the 1890s.
Brick foundations were not designed for earthquakes, and the mortar softens with age. Replacement is often required before a major remodel, and it pairs naturally with seismic bolting.
▦ The redevelopment blocks
Between the 1950s and the 1970s, the Redevelopment Agency demolished much of the Fillmore and rebuilt it as superblocks, towers, and housing cooperatives. Their walkways, ramps, and courtyards are now 40 to 60 years old.
At that age, steel corrosion and spalling start to show. A lasting repair cuts back to sound concrete instead of skim-coating over the damage.
§ Tenants and timelines
Much of the neighborhood is rent-controlled, multi-unit housing. If work would ever require a tenant to move out temporarily, San Francisco’s Rent Ordinance has notice and relocation rules, so check with the Rent Board or your attorney first.
In practice, most foundation and stair work can be sequenced so occupants stay home. We build the schedule around access to every unit.
