Serving Walnut, CA and surrounding areas. (909) 546-5193
Walnut Masonry is a locally owned masonry contractor serving Pomona, CA with concrete block walls, foundation repair, tuckpointing, and retaining wall construction. We have been working on Pomona homes since 2019 and respond to estimate requests within one business day.
Pomona homeowners frequently replace aging cinder block fences and yard enclosures that were built in the 1950s and 1960s and are now crumbling at the base. Our concrete block wall service handles new construction and full replacements, with proper footings sized for Pomona's clay-heavy soil.
Many of Pomona's 1940s through 1960s homes have raised foundations that are now showing their age - cracks, efflorescence, and sections where the block or brick has shifted. The expansive clay soil under most Pomona properties moves with every wet and dry season, and that movement is the most common reason foundation problems develop here.
Pomona's summer heat - regularly above 95 degrees and sometimes topping 105 - dries out mortar faster than it would in a coastal climate. Mortar in chimney stacks, brick veneers, and block fences on homes that are 40 or more years old is often at the point where it is crumbling at the joints and no longer doing its job.
Pomona properties with sloped rear yards, especially in neighborhoods closer to the foothills, depend on retaining walls to hold back soil and direct drainage. Santa Ana wind events and winter rains put added stress on older walls, and a wall that leans or cracks needs attention before the next rainy season.
Fall Santa Ana winds that push through Pomona every year crack mortar joints and loosen chimney caps on older homes. Lincoln Park historic homes and other pre-war properties in particular have chimney stacks that need careful mortar matching to preserve the character of the original construction.
Concrete driveways on Pomona properties built in the 1950s and 1960s are now 60 or more years old, and many are cracked, settled, or beginning to crumble at the edges from decades of clay soil movement and UV exposure. Paver replacements give older driveways a fresh surface that can be adjusted if the ground shifts again.
Pomona is one of the larger cities in the San Gabriel Valley, covering about 23 square miles with a housing stock that skews older. A significant share of the city's homes were built between the 1940s and 1960s, and those homes are now entering the age range when original masonry, mortar, and concrete flatwork start to fail. The city's hot, dry summers - with temperatures that regularly reach the mid-90s and sometimes climb past 100 degrees - accelerate that deterioration. Stucco cracks, mortar dries out, and caulking around windows and doors shrinks. When the winter rains arrive, water finds those openings and causes damage that costs more to fix than the original repair would have.
The clay-heavy soils under most Pomona lots also move with every wet and dry season, which is the primary reason concrete driveways, patios, and retaining walls crack over time - it is not just age, it is the ground itself shifting underneath the slab. The Lincoln Park neighborhood adds another layer of consideration: historic homes there from the late 1800s and early 1900s need material matching and careful craftsmanship to preserve what makes them worth protecting. A masonry contractor who does not understand the range of building stock in Pomona - from postwar ranch homes to Victorian-era historic properties - will not serve every homeowner here well.
Our crew works throughout Pomona regularly, and we understand the local conditions that affect masonry work here. Structural permits in Pomona go through the City of Pomona Building and Safety Division, and we pull from that office regularly. We know the local review timelines, what inspectors typically flag, and how to keep a permitted project on schedule.
Pomona sits at the eastern edge of Los Angeles County where the San Gabriel Valley meets the Inland Empire, bordered by cities like Diamond Bar, Ontario, Chino, and Claremont. The 10, 60, and 71 freeways all run through or near the city, which makes logistics for material delivery and crew movement straightforward. Whether a job is near the Fairplex on the west side of the city, close to Cal Poly Pomona on the east, or in the historic Lincoln Park neighborhood in the center, we know how to get there and what to expect when we arrive.
We also serve the surrounding communities. Our nearest base is in Walnut, just to the east, and we regularly work in Diamond Bar as well. If you have a neighbor who needs masonry work, we can often schedule nearby jobs together.
Reach us by phone or through our contact form, and we respond within one business day. Tell us what you are seeing - cracked block, a leaning wall, a driveway that has been settling - and we will schedule a free on-site visit.
We visit the property, assess the scope, and give you a written estimate before any commitment is made. If a permit is required by the City of Pomona, we tell you exactly what is needed and include the permit cost in your quote.
We schedule work at a time that works for you. Most jobs in Pomona run one to five days depending on scope. You do not need to be present for the full duration - we confirm access arrangements with you in advance.
When the job is done, we clean the work area and walk through the completed work with you before we leave. If anything does not meet your expectations, we address it on the spot.
We serve all of Pomona - from Lincoln Park to the neighborhoods near Cal Poly. No obligation, no pressure.
(909) 546-5193Pomona is one of the most historically layered cities in Los Angeles County, with a housing stock that ranges from Victorian-era homes in the Lincoln Park historic district - recognized as one of the most intact historic residential areas in the Inland Valley - to mid-century ranch homes and postwar tract development across the rest of the city. Most of the city's single-family neighborhoods were built between the 1940s and 1970s, leaving a large share of the housing stock now between 55 and 80 years old. The Fairplex, home of the Los Angeles County Fair, anchors the western side of the city, while Cal Poly Pomona and Western University of Health Sciences sit on the eastern edge near the Diamond Bar border. According to Wikipedia, Pomona covers about 23 square miles and has over 150,000 residents.
The city is well-connected by freeways - the 10, 60, and 71 all run through or near Pomona - and sits at the natural gateway between the San Gabriel Valley and the Inland Empire. The residential neighborhoods near downtown are denser, with smaller lots and homes built close together. Neighborhoods closer to the foothills and the city's northern edge tend to have more sloped lots and more demand for retaining wall and drainage work. If you are in a community bordering Pomona, our service area extends to Rowland Heights to the east and West Covina to the north.
