We come out, walk the area with you, and inspect what is actually going on. You get a written scope of work with a clear price before any work is agreed to. We explain the repair in plain terms so you know exactly what you are paying for.
Once you approve the estimate, we schedule the crew and get started. We handle permits where required, keep you informed of progress, and do a final walkthrough before we leave. The work area is cleaned up every day.

We know Walnut Creek's clay soils, earthquake exposure, and older housing stock. A local crew that works here every day handles your project differently than someone who drives in from out of the area.
Every project comes with a written warranty. We stand behind the work with documentation you can keep - which matters if you sell your home or file an insurance claim down the road.

The crew came out the same week I called and had the chimney mortar fully repaired in one day. I had been putting it off for two years worrying it would be a big production. It was not. Everything was cleaned up before they left.
Marcus T., Walnut Creek - Chimney repair
We needed a retaining wall replaced on our hillside lot in Northgate. They walked the slope with us, explained exactly what they were doing and why, and finished on the timeline they gave us. The wall looks like it has always been there.
Linda R., Walnut Creek - Retaining wall construction
Our foundation had been showing cracks since the dry summer. They came out, did a full inspection, explained the cause in terms I actually understood, and handled the permit through the city. The repair has held through two rainy seasons now.

We respond within 1 business day - no automated replies. This estimate is completely free with no obligation to book. Once you submit, someone from our office will call you to schedule a free on-site visit, walk the project with you, and give you a written quote before any work begins.

Water is the most common cause of masonry damage - it enters through failing mortar joints, freezes in hairline cracks, and slowly breaks brick apart from the inside. If you see white staining on your brick face after a rainstorm, water is already moving through the wall. The Brick Industry Association has detailed guidance on identifying and preventing moisture damage in brick structures.
Not all foundation cracks are emergencies. Hairline vertical cracks from normal settling are common in newer homes. Diagonal cracks running from door or window corners, or horizontal cracks in block walls, are more serious and deserve a professional look. Catching the difference early can save thousands.
Concrete tends to outperform asphalt in hot, dry inland climates like Walnut Creek's - it resists the UV breakdown and surface softening that asphalt is prone to in summer heat. Concrete also holds up better against the freeze-thaw cycles from the seasonal temperature swings in the East Bay hills.
In California, masonry contractors must hold an active license from the Contractors State License Board. You can verify any license in under a minute at the CSLB website. A licensed contractor will also carry general liability insurance - ask to see a certificate before work begins.
Tree roots grow under concrete and pavers looking for water, and they will heave the surface as they expand. In Walnut Creek's older neighborhoods, large established trees near driveways and walkways are a consistent source of cracking. Addressing root-lifted concrete early prevents the damage from spreading to the base.
If the mortar joints are crumbling but the bricks themselves are solid, tuckpointing is the right fix - it is significantly less expensive than replacement. If bricks are spalling (flaking apart on the surface), hollow-sounding when tapped, or shifting out of alignment, you likely need brick replacement alongside new mortar.
Walnut Creek Masonry & Concrete is a licensed and insured masonry contractor based in Walnut Creek, CA, serving 12 cities across Contra Costa County since 2020. We hold an active contractor license through the California Contractors State License Board - the issuing authority for all masonry and concrete work in California. Since 2020, we have completed masonry projects across all 16 of our service areas, from foundation repairs and chimney rebuilds to custom outdoor kitchens and stone veneer installations. Learn more about our team and our approach.
If a contractor quotes a large job without doing an on-site inspection, or pushes you to sign before you have time to review the estimate, get another opinion. A legitimate masonry contractor will walk the work area with you and give you a written scope before asking for any commitment.
Masonry problems rarely stay the same size. A small crack in failing mortar can let in enough water over one rainy season to damage the brick behind it, turning a $600 tuckpointing job into a $3,000 repair. The most expensive thing you can do is wait and see.
For most exterior masonry - tuckpointing, brick repair, chimney work - fall is the best window. The dry summer has revealed where the damage is, the heat has passed, and you can get fresh mortar fully cured before the rainy season starts in late November.
For guidance on preserving historic and older masonry, the National Park Service Preservation Briefs are an authoritative resource used by masons throughout California. Have questions about your specific project? Call us at (925) 532-0850 and we will talk through it with you at no charge.
Walnut Creek is a city of about 70,000 residents at the base of Mount Diablo State Park in Contra Costa County. The majority of homes here are owner-occupied, with median home values well above $900,000. Most of the housing stock was built between the 1950s and 1980s - homes in that age range regularly need masonry attention that has been building up for decades. Neighborhoods like Northgate, Lakewood, and the streets near downtown each have their own character, but most share the same expansive clay soils that cause seasonal cracking and foundation movement.
Walnut Creek sits in an inland valley that gets significantly hotter summers than coastal Bay Area cities - temperatures regularly reach the high 90s, and that heat dries out mortar, cracks caulk, and splits older concrete faster than most homeowners expect. Hillside lots in Northgate and near the Mount Diablo foothills have retaining walls, stepped driveways, and drainage systems that flat-lot homes do not need. Mature trees - especially near Heather Farm Park and through the older neighborhoods - put root pressure on driveways, walkways, and foundations that shows up as heaving and cracking over time.
Walnut Creek Masonry & Concrete has worked throughout Walnut Creek since 2020, from homes near Broadway Plaza to hillside properties in Northgate. We understand what the local soil, climate, and housing stock mean for masonry work here - and that knowledge shapes how we approach every estimate and repair. If you are a Walnut Creek homeowner dealing with cracked brick, settling foundations, or any masonry project, we are ready to help.
