Piedmont homes and what they ask of masonry
Piedmont is almost all houses, and most of our calls here come straight from homeowners. The homes tend to be older and well built, with brick chimneys, stone garden walls and front steps that have done decades of work.
We do the same work across the East Bay, from Oakland right next door to the cities north of Berkeley. What sets Piedmont apart on the job is the ground. Many lots here slope, so a garden wall is usually holding back soil, steps climb from the street to the front door, and brick and mortar often get carried in by hand. That's why we work out drainage, footings and access before we price anything.
Masonry services we offer Piedmont homeowners
Older Piedmont houses often sit on brick or early concrete foundations, and when cracks show or a corner settles, we find the cause before we patch anything.
Brick chimneys here have stood through a lot of years. Loose bricks, a cracked crown or crumbling joints near the roofline are the usual reasons we get called.
When mortar on an older brick wall turns sandy, we rake out the worn joints and pack in fresh mortar so the wall sheds water again.
A brick with its face flaking off, in a garden wall or step, can usually be cut out and swapped for a match without rebuilding the thing.
Steep driveways are common here, and pavers on a well-packed base give tires grip and let us reset one section instead of breaking out concrete.
On Piedmont's sloped lots a retaining wall holds back real weight, so we build the footing, drainage and backfill for it, not just the face.
For an older house where the brick, stone and mortar have all worn together, we repair what's failing and match the old work rather than starting over.
For a new masonry fireplace or a rebuilt firebox, the brick box the fire sits in, we pick brick or stone that suits an older room.
Thin stone set over a plain wall can dress up a foundation or garden stair, and we spend our time on the backing, because that's what holds it.
When a yard needs a solid wall along a drive or a property line, we build block walls with steel and grout where the design calls for them.
When an addition or a rebuilt section of an older house needs new foundation walls, we lay concrete block on a proper footing so it carries the house.
On a terraced Piedmont yard, a level patio is often the spot for a grill counter, and we build the block or brick base and stone face.
Paths and steps that climb from the street to the front door are common here, so we lay walkways with even treads and a firm base under them.
For a new garden wall that has to sit beside older brick, we match brick and mortar color and build it on a real footing.
Stone garden walls and steps on older Piedmont properties often need a few stones reset or a section relaid, and we work with the stone that's already there.
When a few joints are open on a chimney or wall, pointing them now is a small job that keeps water from turning it into a bigger one.

Working in Piedmont starts with the city's permit
The City of Piedmont issues building permits for most construction projects and repairs, so on a lot of jobs here the permit, not the mortar, sets the start date. Before you hire anyone, look up their license with the Contractors State License Board, the state board that licenses California contractors. We're licensed and fully insured, we talk through the permit side with you before work starts, and when your job needs one, we handle the paperwork with the city's permit office.
Price here turns mostly on the site and on how much is really failing. A narrow street means smaller deliveries, a slope means more carrying, and old brick takes time to match in color and texture, while the schedule turns on the permit and the size of the job. I'd rather tell you a wall is fine than sell you a new one, and your own figure comes from the estimate visit. We work the same way up in Pinole and the other East Bay cities around Berkeley, but Piedmont lots usually ask for more planning before the first brick moves.
Why Piedmont houses keep needing masonry work
Old brick usually outlasts the mortar around it. On many houses here the brick is still sound and the joints have gone soft, and once they open, water gets in and starts loosening the brick on either side. We repoint with a mortar softer than the brick, so the joint wears instead of the brick. The worst thing you can do to old brick is patch it with mortar harder than the brick itself. It looks fine for a few years, and then the brick pays for it.
Sloped lots put masonry to work. When a garden wall leans or a step rocks, it's usually water and weight behind it, so we look at drainage first, because a new wall with nowhere for water to go is just a slower version of the old one.
What to expect when you hire us in Piedmont
Here's how a job goes from your first call to the final walk-through, and where the city's permit fits in.
Call or send the form
Tell us what you're seeing, and we'll set a time to come out. A couple of photos help, but you don't need to know what the job is called.

We sort out the permit
When your job needs one, we handle the paperwork with the city, and permits that need plans and review can take several weeks or months. I'll tell you at the estimate which kind of review your job is likely to face.

Questions about masonry work in Piedmont
Do I need a permit for masonry work in Piedmont?
Usually yes, because the city issues building permits for most construction projects and repairs. Its list of projects that don't need a building permit is mostly finish work like painting, carpeting and most tiling, plus a few small yard items, and even work on that list has to meet building codes and may still need an inspection. We settle which applies to your job at the estimate.
How do I get a building permit for a masonry project in Piedmont?
You apply online, because the city no longer takes paper or email applications, and only a licensed California contractor or a property owner acting legally as an owner-builder can get one. On our jobs we file it for you. If you're doing the work yourself, the application is on the city's permit page.
Does a retaining wall or patio need a permit in Piedmont?
A retaining wall up to 30 inches tall, measured from the top of the grade to the top of the wall, is on the city's no-permit list unless it's holding up extra weight above it, such as a slope or a driveway. Otherwise retaining walls, patios, site stairs and drainage come under the city's site improvement permit, and most above-ground exterior changes need design review first, which brings a building permit with it even on small work. Work in the public right of way, or work that sends more stormwater to the street, can also need an encroachment permit from Public Works.
What affects the cost of masonry work on a Piedmont house?
Cost comes down to the size of the job, the access on your lot and the permit, since the city's permit fees vary by permit type and the job's value. Repointing a chimney with good brick is a far smaller job than rebuilding it from the roofline up, and I'll tell you which one you actually need. Call (510) 345-1156 and I'll come take a look.
What causes a garden wall to lean on a sloped lot in Piedmont?
Usually it's water building up behind the wall with nowhere to go, pushing on it from the uphill side. A footing too small or too shallow for the load does the same thing more slowly. We dig out the back, add drainage and rebuild on a proper footing, because resetting the face alone just buys a few years.
What happens if masonry work is done without a permit in Piedmont?
The city can fine you and require you to undo the work. That's an expensive way to build a wall twice, which is why we settle the permit question before anything starts.
