Redwood City Masonry & Concrete is the masonry contractor Millbrae homeowners call for concrete block walls, retaining wall construction, chimney repair, and tuckpointing. We have served the Peninsula since 2017 and understand what the hillside homes west of El Camino Real actually need from a masonry crew.

Millbrae properties with sloped lots often need block walls to separate grade levels, manage drainage, or create level areas for driveways and patios. Concrete block holds up well to the combination of hillside soil pressure and the seasonal moisture that comes with Bay Area winters. Our concrete block wall work is built with proper footings and drainage provisions so the wall does not lean or crack after the first few wet seasons.
The hill streets west of El Camino Real are full of sloped lots where soil pushes against old retaining walls built decades ago. When those walls start to lean or crack, the winter rains make the problem worse fast - saturated soil is much heavier than dry soil, and an undersized wall will not hold it. We build new retaining walls sized for the actual load of each site and repair existing ones that have shifted but can still be stabilized.
Most Millbrae homes from the 1950s and 1960s have original brick chimneys that have been through decades of wet winters, marine fog, and seismic activity. Mortar joints that look intact from the ground often have deeper erosion that only shows up on a close inspection. Repairing the joints and crown before the next rainy season prevents water from running into the flue and causing interior damage.
Brick walls and chimneys on Millbrae homes from the postwar decades have mortar that has been softening for 60 or 70 years. Marine fog and year-round moisture make the deterioration faster here than in drier climates. Tuckpointing - raking out the degraded joints and refilling them with fresh mortar - seals the wall before the next rainy season reaches it.
Hillside foundations in Millbrae deal with lateral soil pressure on top of the normal expansion and contraction that comes with clay-heavy Bay Area soil. Homes built in the 1950s and 1960s were not engineered to current seismic standards, so foundations that have been absorbing decades of minor earthquake activity and soil movement are worth having assessed if you see cracking, uneven floors, or doors that stick seasonally.
Ranch-style homes in Millbrae often have brick planters, steps, and low garden walls that develop cracks and spalling as the structure settles over decades. Matching the original brick color and texture matters in this city because neighbors are close and the visual character of the street matters to longtime owners. We source replacement material carefully and blend repairs so the finished work does not look patched.
Most homes in Millbrae were built between the 1940s and 1970s, which means the original masonry - foundations, chimneys, brick walls, and concrete flatwork - is anywhere from 50 to 80 years old. At that age, mortar has been softening since it was laid, concrete has absorbed decades of wet-dry cycles, and seismic activity on the Peninsula has gradually widened any small crack that was not addressed early. The combination of an aging housing stock, hillside lots that put lateral pressure on every wall and foundation, and marine fog that keeps masonry surfaces moist for months at a time creates a demand for masonry work that is specific to this city.
Millbrae sits between the San Andreas Fault to the west and the Hayward Fault to the east, and minor earthquakes on either fault can shift a chimney crown or open a wall crack faster than the slow seasonal movement of clay soil. The California Geological Survey maintains updated seismic hazard maps that show how much ground-shaking this part of San Mateo County is designed to absorb. Homes built before seismic codes were updated in the 1980s may not be up to current standards, and a masonry contractor working here should factor that history into every assessment.
Our crew works throughout Millbrae regularly, and we understand the local conditions that affect masonry work here. The hillside neighborhoods west of El Camino Real present equipment access challenges that flat-lot cities do not - narrow, winding streets and sloped driveways mean planning material delivery and crew positioning before the job starts, not on the morning of. We account for that in our estimates.
Millbrae is a compact city where the residential character shifts noticeably from one side of El Camino Real to the other. The neighborhoods closer to the Millbrae BART and Caltrain station tend to have smaller lots and more recent development, while the streets climbing toward the hills have the older ranch homes with the sloped lots and aging masonry that needs the most attention. We work across both sides and tailor the approach to what each property actually has. For permit questions, the City of Millbrae Building Division handles applications for most structural masonry work in the city.
We also serve Burlingame to the north, where we encounter a similar housing stock of mid-century homes. Homeowners in San Mateo to the south are also within our regular service area.
Contact us by phone or through the estimate form and describe what you are seeing - cracks, leaning walls, stucco damage, or anything else. We respond within one business day to schedule a visit.
We walk the property, assess the damage and its likely cause, and give you a written quote covering scope, materials, and price. For hillside properties, we also identify drainage factors that could affect how long any repair holds. There is no charge for the assessment.
For structural work, we apply for the permit with the City of Millbrae Building Division and schedule the job once it is approved. You do not need to manage that process. We coordinate any required inspection visits as the work progresses.
We complete the work to the agreed scope, clean the site, and walk you through what was done before we leave. If a city inspection is part of the permit, we coordinate that visit and provide you with the inspection record.
We serve Millbrae and the surrounding Peninsula cities. No charge for the on-site assessment - just a straight answer about what your property needs and what it will cost.
(650) 587-4252Millbrae is a small city of about 23,000 people in San Mateo County, sitting between San Francisco International Airport to the north and Burlingame to the south. The city is best known for the Millbrae BART and Caltrain station, the only station in the Bay Area where both systems share a stop. East of El Camino Real, the neighborhoods are denser and more recently developed, while the residential streets climbing into the hills to the west are quieter and made up almost entirely of owner-occupied single-family homes from the postwar decades.
The housing stock throughout the hill neighborhoods consists largely of ranch-style and split-level homes built between the 1940s and 1970s. Homes sit on sloped lots with mature landscaping, and stucco exteriors are the norm. Median home values in Millbrae are well above one million dollars, and most homeowners have lived in their homes for years - which means they tend to invest in proper repairs rather than quick patches. The city neighbors Burlingame to the north, where similar housing stock creates similar masonry needs, and San Mateo to the south.
