A mason visits your property, walks the work area with you, and explains what is happening and why in plain terms. You receive a written estimate covering the full scope - labor, materials, and any permit requirements. No mystery line items. If something comes up during the job that was not visible at first, we stop and talk to you before we proceed.
Once you approve the estimate, we schedule the work and give you a day-by-day plan. The crew arrives on time, handles all permits if required, does the job to a professional standard, and cleans up the work area before leaving. After completion, we walk you through everything that was done so you know exactly what you paid for.
We carry a valid California Contractors State License Board (CSLB) license plus full liability insurance and workers compensation on every project. You can verify our license on the CSLB website in about 30 seconds.
We come to your property, look at the work in person, and hand you a written estimate before anything is scheduled. No deposit required to get a quote, and no pressure to commit on the same visit.
We have been working in the San Gabriel Valley since 2016. We know the clay soils, the older housing stock, and the local permit process - which means fewer surprises on your job.
Structural masonry work in San Dimas often requires a city permit. We handle the application, coordinate the inspection, and make sure the city signs off - so you never have to call a building department.

"The tuckpointing on our chimney was done in one day and the mortar color matched perfectly. I walked around the chimney afterward and honestly could not tell where the old joints ended and the new ones started. Exactly what I was hoping for."
Michael R., San Dimas - Tuckpointing
"We had cracks appearing in our drywall every winter after the rains. After the foundation repair, the cracks stopped. The crew showed up when they said they would, explained every step, and cleaned up completely before they left."
Patricia S., Glendora - Foundation repair
"Had a section of retaining wall starting to lean on the hillside side of our yard. They gave us a written estimate the same week, pulled the permit, and had the wall rebuilt in three days. No drama, no surprise charges."
David L., La Verne - Retaining wall construction

Mortar is softer than brick by design - it takes the stress so the bricks don't crack. In San Dimas heat cycles, it degrades faster than in coastal areas. Depending on exposure, original mortar from the 1960s can fail in 40 to 50 years.
Hairline cracks that have not moved in years are usually cosmetic. Diagonal cracks from door corners, horizontal cracks in block walls, or cracks wider than a quarter coin need a professional assessment. Catching them early is almost always cheaper than waiting.
Both work well in Southern California. Pavers handle the wet-dry soil cycle better because individual units can flex without cracking. Concrete is less expensive upfront but can crack as clay soils shift. For driveways on hillside lots, pavers often outlast poured concrete.
Yes. An unused chimney still faces weather - rain, Santa Ana winds, and UV exposure wear down the cap, mortar, and flashing. Water that enters an unused flue can damage the liner and surrounding framing. Annual inspections catch small problems before they become structural ones.
A leaning or cracked retaining wall is holding back tons of soil. When it fails, it can damage the yard, a neighbor's property, or even the home's foundation. Walls over 3 feet tall in California typically require a permit and engineered design for a reason.
Any contractor doing masonry work above $500 must hold a valid CSLB license. You can verify any license on the California Contractors State License Board website at cslb.ca.gov in about 30 seconds. Also confirm they carry liability insurance and workers compensation before work starts. The Brick Industry Association (gobrick.com) offers free guidance on what quality masonry work looks like.

San Dimas Masonry is a licensed and insured masonry contractor based in San Dimas, CA, serving the eastern San Gabriel Valley across 12 cities since 2016.
We hold a valid contractor license issued by the California Contractors State License Board (CSLB) and carry full liability insurance and workers compensation coverage on every project. The CSLB oversees contractor licensing across California and sets the standards for structural masonry work.
Since 2016, we have completed masonry projects across 16 service categories - from foundation repair and chimney rebuilds to retaining walls and outdoor kitchens. We know the clay soils, the older housing stock, and the local permit process in the San Gabriel Valley, which means fewer surprises for you.
If fewer than a third of your bricks are damaged and the mortar joints are the main issue, repair is almost always the right call. Full replacement makes sense when the structural integrity is compromised across a large area, or when bricks have spalled deeply and sourcing matches is not practical.
Yes. Mortar cures best between 50 and 85 degrees Fahrenheit. In San Dimas, late spring and fall are ideal windows - after the rainy season ends and before peak summer heat. Work done in extreme heat needs careful management to avoid premature drying that weakens the mortar.
A reputable contractor should provide a written warranty covering both labor and materials - not just one or the other. Ask specifically what it covers and for how long. For structural repairs that required a city permit, you also get the protection of an independent city inspection confirming the work met code.
For technical guidelines on mortar compatibility and masonry installation standards, the Brick Industry Association publishes free technical notes for both contractors and homeowners. Have a specific question about your project? Call (562) 358-3205 or send us a message.
San Dimas is a city of about 34,000 people in the eastern San Gabriel Valley, sitting at the foot of the San Gabriel Mountains between Glendora to the east and La Verne to the west. The city borders San Dimas Canyon, which runs up into the mountains and gives the northern neighborhoods their distinctive hillside character - and their unique set of drainage and slope challenges.
The city is home to Raging Waters, one of the largest water parks in California, and has been a recognizable part of the greater Los Angeles area since the post-war suburban boom. Most of the housing stock was built between the 1950s and 1980s, and roughly two-thirds of homes are owner-occupied - meaning most residents have a long-term stake in keeping their properties in good shape. The San Dimas Walnut Festival, one of the oldest community celebrations in the valley, reflects the city's roots as an agricultural town before it became the close-knit suburb it is today.
For masonry contractors, San Dimas presents a specific set of conditions: expansive clay soils under most of the city that expand in winter rain and shrink in the dry summer heat, older homes with mortar that has reached or exceeded its natural lifespan, and hillside lots near the San Dimas Canyon Regional Park that require retaining walls and drainage work more often than flat properties. San Dimas Masonry has been working in this city and the surrounding San Gabriel Valley since 2016, and we understand what the local soil, climate, and housing stock demand from masonry that is built to last.
