Do you need a stone mason, or just new mortar?
Stone masonry in Berkeley usually means one of two jobs. One is building a new wall or fence in natural or manufactured stone, set in mortar or laid dry. The other is repointing an old wall by raking the worn mortar out from between the stones and packing in new, so the wall sheds water and holds together again.
Most of the stone calls we get come from people with an older garden wall that's going sandy at the joints, or a yard that needs a wall it doesn't have yet. The price moves with the wall's length and height, the stone you pick, how deep the old mortar has to come out and how easy the wall is to get to. The schedule mostly turns on whether the city wants a permit before we start. Your estimate spells out what we'd do and why, so you can see where the money goes.
How do you know your stone wall needs work?
Joints turning to sand
If the mortar crumbles when you run a thumb along it, it's worn out, and wearing out is what good mortar is supposed to do eventually. Leave it, and rain works into the gaps until the stones start losing their grip on each other.
Stones that rock or shift
A stone that moves when you push it means the joints around it have gone deep, or the wall itself has moved. Caught early, that's often a repoint. Left alone, it usually turns into rebuilding that stretch.
Cracked stone beside grey patches
Hard grey cement smeared into an old wall, with chipped or cracking stone around it, usually means someone used a mortar stronger than the stone. That mortar won the argument and the stone lost, and a cracked stone is a lot harder to fix than a joint.
How we handle stone masonry, new walls and old
On a repoint, we rake the worn mortar out until we reach sound material, clean the joints, then pack in new mortar and tool it to match how the wall was finished. On a new wall, we dig out, set the footing and lay the stone course by course, in mortar or dry-stacked depending on the wall. Either way, I pick a mortar softer than the stone, so the joints take the wear and the stone doesn't. On older walls that means passing on the hard cement mixes, because a joint is cheap to redo and a broken stone isn't.
If the wall you're worried about is brick, the same thinking applies, and that work is covered under brick pointing. When the stone you're looking at is the house's foundation, or cracks run up into the walls above it, that's a foundation repair question, and I'll tell you so before anyone touches the stone.
Repointing an existing wall
This suits a wall that's still standing straight but whose joints have gone soft or open. We replace the mortar and leave the stone where it is, which is the least work that gets the wall right.
New mortared stone wall
This suits a garden wall, planter or retaining wall that needs to stay put and shed water. Mortar gives a solid, tidy face, which is why it's the usual pick for walls beside paths and driveways.
Dry-laid stone wall
This suits a low garden or landscape wall where you want the stone to show without mortar lines. It holds by how the stones are fitted and leaned back, so it works better low than tall.

What happens when you call us about a stone wall in Berkeley?
Here's how a stone job runs from your first call to the walk-through at the end, and who you'll deal with at each step.
Call or send the form
Call (510) 345-1156 or use the form, and we'll set a time to see the wall. Tell us roughly where it sits on your lot, since that can change the permit side.
I look at it myself
I go over the stone and the joints and give you an estimate that says what we'll do and why. If the wall only needs a few joints, or nothing yet, that's what it'll say.
Settle any permit questions first
Before work starts, we go over whether the city wants a permit for your wall, using the rules laid out below. Nothing gets built until that's settled.
Build it and walk it together
We do the work and clean up after ourselves. Then we walk the finished wall with you, so you see every joint before we call it done.

Repairing older stone in Berkeley since 2021
I started this business in Berkeley in 2021, and careful repair on older brick and stone is what we're known for. I learned under a boss who made me redo a joint until it was right, and I still work that way.
Mortar is meant to wear out before the stone does, so the best time to look is while it's still only the joints. Ask for your estimate, or call (510) 345-1156.
Stone masonry, walls and permits in Berkeley
In Berkeley, the Permit Service Center issues permits for construction work and most repairs, and the city's list of work exempt from a building permit is where a stone wall's paperwork starts. A retaining wall can skip the building permit if it's no more than 4 feet tall, measured from the bottom of the footing to the top of the wall, so the footing counts. A wall holding up extra weight behind it, like a driveway or a slope, loses that exemption. A retaining wall in a required setback, the strip along your property lines that zoning keeps open, needs a zoning permit either way. If what we're building is a fence, the city's fence rule applies instead, with a zoning permit over 6 feet and no building permit under 7. For other stone work, like a freestanding garden wall, we check with the city rather than guess. Even exempt work still has to meet the state building code and the city's own laws, and it can still need a zoning permit. We talk all of this through with you before work starts, and when your job needs a permit we handle the paperwork with the permit office.
On jobs around here we mostly meet older houses with stone garden walls, steps and retaining walls, and a fair number of them have been patched with hard grey cement somewhere along the way. We see the same thing on jobs in Kensington and Piedmont. We're based in Berkeley and work across the East Bay cities around it.
Questions about stone masonry in Berkeley
Do I need a permit for a stone retaining wall in Berkeley?
You don't need a building permit if the wall is 4 feet or less from the bottom of the footing to the top and holds up no extra weight. A wall in a setback still needs a zoning permit. Above 4 feet, or with a load behind it, plan on a permit, which we sort out with you before we start.
How do I choose the right mortar for my stone wall?
Choose a mortar softer than the stone, so the mortar wears and gets replaced while the stone stays whole. Preservation guidance for historic buildings warns that harder, less permeable mortars like Portland cement can leave the stones soaking up moisture and failing, and that damage can be structural, not just cosmetic. On an older wall, settle the mortar before work starts, and ask any mason how their mix compares with your stone.
Can a handyman do a small stone masonry job in California?
Only if the job stays within the state's $1,000 small-job limit, needs no permit and the handyman has nobody working for them on it. Any stone job that needs a permit falls outside that, so it takes a licensed contractor.
What is repointing on a stone wall?
Repointing is raking the worn mortar out of the joints and packing in new, which keeps a stone wall going because the mortar is the part meant to be replaced. You'll also hear it called pointing, or tuckpointing, though that last name is a loose fit. On stone with wide joints, the old mortar may have to come out several inches deep.
What is the best way to remove old mortar from a stone wall?
Preservation guidance for historic masonry says hand chisels and mash hammers, the short heavy ones, are the traditional way and in most cases the least risky for the stone. It's slow, labor-heavy work, but that same guidance credits it with the best finished job. Your estimate says how we'd take the mortar out of your wall.
How much does stone masonry cost in Berkeley?
We price each wall after I've seen it, because the cost comes from the wall's length and height, the stone, how deep the old mortar runs and how easy the wall is to reach. Repointing a sound wall usually costs less than rebuilding a section, and a new wall that needs a permit adds that step. Call (510) 345-1156 to set up a visit.
