Concord's houses, yards and fence lines
Concord is a big city made up mostly of single-family neighborhoods, and the calls we get here look a lot like the ones from Walnut Creek and Pleasant Hill next door. Plenty of the houses we see are older one-story homes with a brick chimney, brick planters out front and a back fence that's seen better days. Closer to the hills the lots tilt, so a flat patio or a usable side yard usually takes a wall.
That mix shapes most jobs here, because older brick needs new work that matches it and sloped ground needs digging and drainage before anything goes up. The price usually turns on how much old work comes out and how much dirt we move, and the schedule turns on whether the city wants a permit first.

Our services in Concord, CA
- Brick repair
Brick planters, steps and trim on a lot of Concord houses loosen once the mortar behind them wears out. Our brick repair uses brick and mortar matched to what's there.
- Chimney repair
Many older Concord houses still have their first brick chimney, and the top takes the most wear. We rebuild loose rows of brick and refill the worn joints below them.
- Tuckpointing
Mortar on older Concord brick wears back from the face well before the brick does. We tuckpoint it, grinding out worn joints and packing them with fresh mortar.
- Retaining wall construction
Sloped yards in Concord often need a wall to hold the hill or level a patio. We build them with a drain behind so water doesn't pile up against them.
- Walkway construction
Front walks in Concord's older neighborhoods are often cracked concrete that tree roots have lifted. We tear out the old walk and lay a new one on a packed base.
- Concrete block walls
Old wood fences along Concord property lines give out, and a block wall is the longer-lasting swap. We set it on a poured footing so it stands straight.
What Concord houses and slopes ask of masonry
Most of what we're called out for here is mortar that's done, not brick that's done. I'll show you a joint you can scrape out with a key and explain why it failed, because patching old brick with a hard, cement-heavy mortar pushes the damage into the brick itself, and that's a worse problem than the one you started with.
Sloped lots are the other half of the work in Concord. A retaining wall cut into a hillside or a new walk that meets the sidewalk moves soil, and the city says that when a project moves soil or reaches into the public strip along the street, you apply for separate grading and encroachment permits with its Engineering Division. That step belongs early in planning, so we sort out what your job needs before anyone digs, and when a permit is needed we handle the filing and line up the inspections with the city.

Brick, block and stone work
Concord masonry questions answered
How do I find out if my masonry project needs a permit in Concord?
Start with the city's Permit Center, which points you to a way to look up zoning information, see which permits a project requires and estimate the fees. The city's permit list for single-family homes and duplexes doesn't name brick, block or stone work, so that list alone won't settle it for a wall or a chimney. Checking first tells you what your job needs before you ask for bids, and if it's still unclear, we check with the permit office for your address before work starts.
Does a contractor from outside Concord need a Concord business license?
Yes. The city requires a business license to do business in Concord, state-licensed contractors included, and that covers contractors whose office is outside the city. A crew coming over from Vallejo or anywhere else falls under that rule, so it's a fair thing to ask any contractor you're weighing.
When does a masonry contractor need a California contractor license?
The Contractors State License Board requires a state license for anyone building or altering a structure in California when the project needs a building permit, uses any other workers, or totals $1,000 or more in labor and materials across its contracts. So a small repair can call for a licensed contractor just as much as a new wall can. We're fully licensed and insured.
How can I check if my Concord house is in an earthquake hazard zone?
Type your address into EQ Zapp, the California Geological Survey's statewide map tool, and it shows whether the property lies in any of its mapped earthquake hazard zones. If you look it up before I come out, tell me what it showed, and I'll keep it in mind when I go over your chimney and any tall walls.
How much does masonry work cost in Concord?
The cost of a masonry job in Concord comes down to how much we build or fix, how much old work has to come out first, and how closely the new brick, block or stone has to match what's there. Digging into a slope, hauling soil, a back yard that's hard to reach and any permits add to it, while plain block or a simple paver pattern costs less than matched brick or natural stone. I'll walk the job with you, explain what I'd do and why, and give you the number for your house.
How long does a masonry job in Concord take from start to finish?
The schedule usually turns more on what comes before the masonry than on laying it, mainly any permit the city asks for, the grading or street-side permits a sloped or sidewalk job can need, and finding brick or stone that matches. Once we're building, mortar and concrete need time to set before the next step goes on, so some days the job sits on purpose. I'll tell you what to expect for your job when I come out.
