San Ramon homes, hills and the masonry they need
San Ramon is mostly homes on quiet streets and rolling hills, from older single-story houses to the newer two-story neighborhoods climbing into Dougherty Valley, with shopping and office parks along the freeway. On jobs here I see a lot of stucco fronts with stone veneer, backyard walls holding up graded lots, paver driveways and brick fireplaces. The work feels a lot like what we do next door in Dublin, just with more slope to deal with.
So many lots here were cut and graded to make room for the house that the ground behind a wall or under a patio is often doing more work than it looks, and that's where I start when something cracks or leans.
Masonry services we bring to San Ramon homes
Foundation repair
When a foundation crack keeps widening or a corner settles on a graded lot, we find what's moving it before we repair the concrete.
Chimney repair
Chimneys on San Ramon's older homes lose mortar to winter rain and summer sun, so we rebuild cracked crowns and reset loose brick before pieces come down.
Tuckpointing
When the mortar between your bricks turns sandy or sinks back, tuckpointing replaces it with fresh mortar in a matching color, keeping water out of older brick walls.
Brick repair
Cracked, flaking or loose bricks on a planter, front step or garden wall can be cut out and replaced one at a time with brick that blends in.
Driveway pavers
Pavers flex where a poured driveway would crack as the ground moves, and we set them on a packed base so they sit flat.
Retaining wall construction
Sloped backyards here often need a wall to turn hillside into usable yard, and we size the footing and height to the slope you've actually got.
Masonry restoration
When old brick or stone on a house, wall or chimney looks tired and patched, restoration cleans, repairs and repoints it so it looks right again without starting over.
Fireplace installation
A new masonry fireplace gives a family room a real centerpiece, and we build it in brick or stone to suit the rest of your house.
Stone veneer installation
Plenty of San Ramon homes have plain stucco fronts that stone veneer dresses up, and we install it over proper backing and a moisture barrier so water drains out.
Concrete block walls
Block makes solid property-line and privacy walls between San Ramon backyards, and we fill and reinforce the cores so they stand up to the soil pushing on them.
Foundation block wall installation
When an addition, garage or crawlspace needs a new foundation wall, we lay reinforced block on a footing sized for the ground at your address.
Outdoor kitchen masonry
Warm Tri-Valley evenings make backyard cooking popular, and we build outdoor kitchen islands, counters and grill surrounds in block, brick or stone on a solid base.
Walkway construction
A brick, stone or paver walkway gives you steady footing to the front door or side yard, and we pitch it so rainwater runs off.
Brick wall installation
For a garden wall, planter or low front wall with some character, new brickwork with crisp joints ties in with older homes and warms up newer ones.
Stone masonry
Natural stone suits San Ramon's hillside yards and oak-shaded lots, and we lay steps, seat walls and borders in stone with joints made to hold up outdoors.
Brick pointing
When only a few joints have cracked or washed out, pointing fills them with fresh mortar shaped to match, a smaller fix that keeps a sound wall sound.

Working in San Ramon: permits, licenses and what sets the price
When a San Ramon job needs a permit, it comes from the city's Building & Safety office, and that review has to clear before we start, so it's usually the one part of the schedule nobody can hurry. If your wall or outdoor kitchen is part of an addition or remodel, the city's planning staff may need to approve it before the building permit is even issued, which adds a step. We check with the city on every job and take care of the paperwork and inspections ourselves. Before you hire anyone, look them up with the state Contractors State License Board, and know that a contractor set up in San Ramon itself also needs a business license from the city. We're fully licensed and insured.
On price, the size of the job, the material you pick and how much old brick, block or concrete has to come out first move the number most, and the written estimate after my visit spells all of that out. Beyond the permit, the schedule turns on the weather, since heavy rain holds up footings and mortar work. We've been at this since 2013, based in Castro Valley, and we come up 680 to San Ramon and over to Pleasanton often, so getting a crew out here is easy.
What the soil and slopes do to San Ramon masonry
The city itself has found expansive soil across San Ramon, the kind of clay that swells in the wet months and shrinks as it dries out, though that's a citywide finding and not a report on your particular lot. That movement shows up as stair-step cracks in brick, mortar dropping out of joints, pavers that heave or sink, and walls that start to lean. Before we patch anything I want to know whether water, a shallow footing or the soil itself started it, because a repair that ignores the cause just cracks again, so we look at drainage, footing depth and the base under pavers first.
Hillside lots are the other big one. When a slope gets cut back for a yard, the wall at the bottom carries the soil and the water behind it, and walls without gravel backfill and drain holes are the ones I see bowing, so we build drainage in behind the walls we put up.
How a San Ramon masonry job runs from your call to the final walk
Here's how a job goes from your first call to the day we walk the finished work, and who you'll be dealing with along the way.
Call or send a message
You call (510) 264-7156 or send the form, and I set a time to come out to your San Ramon property. It helps if you can be there so you can show me what's bothering you.
Look at the work together
I walk the job with you, tell you what I think caused the problem and what your choices are, then follow up with a written estimate that spells out the work and materials. You'll know exactly what you're paying for before anything starts.
Sort permits and schedule work
Once you say go, we check with the city whether your job needs a permit and handle the paperwork and inspections. The city's review comes before we can start, so we put your job on the calendar once it clears.
Build it and walk it
My crew does the work with me checking in as it goes, so questions get answered on the spot. At the end you and I walk the finished job together.
Questions about masonry work in San Ramon
How do I know if my retaining wall needs a permit in San Ramon?
A retaining wall in San Ramon doesn't need a permit if it's no more than 4 feet tall, measured from the bottom of its footing to the top of the wall. That exemption is off if the wall holds back a surcharge, which is extra weight from the ground above, such as a cut into a hillside, or if it sits in an engineered grading development like Dougherty Valley. Plenty of backyard walls here hold back a cut slope, so I check yours against the city's rules before we plan anything.
When does a masonry contractor need a California state license?
A contractor needs a state license when the job requires a building permit, uses any additional workers, or costs $1,000 or more in labor and materials combined. The state board lists only a job with no permit, no employee labor and a combined value under $1,000 as possibly exempt. That's a small job, so if you're planning a wall, a chimney repair or a paver driveway, ask to see a license.
How much does masonry work cost in San Ramon?
Your price comes from the written estimate I put together after seeing the job, because in San Ramon the slope, the soil and the permit question move cost as much as the brick or stone does. A tall wall on a cut hillside can need a permit, deeper footings and drainage, while repointing a garden wall on flat ground is far simpler. How easy it is to get equipment into your yard and haul old material out counts too.
Does a small brick or block garden building need a permit in San Ramon?
A building of 120 square feet or less doesn't need a building permit in San Ramon as long as no electrical or plumbing work goes with it, and anything larger does. So a small block potting shed with no wiring can skip the permit, while a pool house with lights or a sink can't.
If my project doesn't need a permit in San Ramon, does it still have to meet code?
Yes, work on the city's list of home improvements that need no permit still has to meet the building code and San Ramon's other local laws. The exemption only skips the permit, not the rules for how the work gets built. A short garden wall we build without a permit gets the same footing and drainage as one the city inspects.
How do I know if I need a tree permit before building a wall or patio in San Ramon?
On a single-family lot that can't be split further, you don't need a San Ramon tree removal permit unless the tree is a native oak of 6 inches in diameter, measured 54 inches above the ground. Oaks turn up in a lot of hillside yards here, so if one sits where your wall or patio would go, check before anyone cuts it. I'll point out any oak that might be in the way when I come out.
