Concrete block walls in San Jose, CA - a wall built for the load it carries
Wood fence giving out, or a slope sliding onto the patio? We build block walls with the height, footing and drainage they need.
Do I need a fence wall or a retaining wall?
A concrete block wall in San Jose is either a fence wall that marks your property line or a retaining wall that holds back soil, and we build both from a poured concrete footing up, with steel and grout set inside the block.
Most calls come from someone whose wood fence has given out and who wants something heavier along the line, or whose yard has a slope that keeps sliding toward the house. The price moves with the wall's height and length, whether it holds back soil, how easily we can reach the spot and the face you choose, and the schedule moves mostly with whether the city needs permits before we dig. If the main job is a hillside, our retaining wall construction page covers that work in more depth. Your own figure comes from the estimate, where I measure the wall and write up what I found and what we'd do.
How we build a concrete block wall
First we pin down whether your wall marks a line or holds back soil, and how tall it'll stand, because that changes how it's built and what the city asks for. Then we dig the trench and pour a concrete footing, which is what keeps the wall from tipping or sliding. Our masons lay the block on it, stand steel bars up in the cores, the hollow centers of the block, and fill those cores with grout so the wall works as one piece against wind or soil pressure. On a retaining wall we plan how water will leave the soil behind it before any dirt goes back. We finish with a cap to shed water and leave the site clean.
Block walls often tie into other work. If the block is going under the house to carry it, that's foundation block wall installation, which is built and inspected as part of the structure. Block is also the usual frame inside a grill island or bar counter, so we lay it for outdoor kitchen masonry and finish it in stucco, stone or tile.
Freestanding block fence wall
This suits a side or back property line where you want privacy, less street noise or a wall that won't rot the way wood does. It takes weather on both faces, so we finish both sides and cap the top to keep water out of the cores.
Block retaining wall
This suits a sloped yard, a raised planter or a cut for a level patio, where soil presses on one side. It gets a heavier footing, more steel and a planned path for water, so it usually costs more per foot than a fence wall of the same height.
Concrete block wall permits in San Jose
In San Jose, the permit question turns on whether the wall holds back soil and how tall it is. A retaining wall more than 2 feet tall, measured from the existing ground, needs a building permit plus a planning permit from the Planning Division. That's a Planned Development Permit if your lot is in a planned development zone, or a Special Use Permit if it isn't. Once the wall measures 4 feet or more from the bottom of its footing to the top, or carries extra load like soil sloping down into it or cars on the ground above, Public Works issues a grading permit too. Which of those your wall needs isn't settled until I've measured it and checked your lot against the city's fence and retaining wall rules. The city recommends a licensed contractor apply, and whoever signs the application is responsible for everything done under that permit, so we check with the permit office first, apply as the licensed contractor and meet the inspector on site.
On jobs here we often find a low garden wall that has turned into a retaining wall as soil piled up behind it over the years. That changes how the city sees it, so I measure from the ground on both sides before we talk about height. We see the same thing on jobs in Campbell and Santa Clara.

Why call us for block walls
I measure every wall myself
I come out to look at the job and take the measurements, and our own masons do the work while I check it as it goes up. You deal with the person who planned your wall from the first visit through the last course of block.
In business since 2013
We've been doing masonry since 2013. I learned the trade under an experienced mason here in San Jose, starting with mixing mortar and cleaning out joints, so I pay attention to the parts of a wall you don't see.
Licensed and fully insured crew
We're licensed and fully insured, so the permit can go in under us and our crew's work on your property is covered by our own policy. The job is backed by our satisfaction guarantee.
On a block wall, the footing and the drainage decide how it holds up, and they're buried once the wall is done, so that's where I look hardest. When you're ready, send us the wall's height, where it goes and whether it holds back soil, and I'll set a time to come out.

Block wall questions from San Jose
How tall can a block fence wall be in San Jose before it needs a permit?
The city requires both a building permit and a planning permit once a fence goes over 3 feet in a front yard or 7 feet in a side or rear yard, and a masonry wall counts as a fence. On a corner lot, the 3-foot line also covers the side yard along the street. I check your lot with the city before we settle on a height.
How much does a concrete block wall cost in San Jose?
The cost depends mostly on height, length and whether the wall holds back soil, since a retaining wall needs a heavier footing, more steel and drainage. When you compare bids, weigh how each builder plans the footing and the steel in the cores as closely as the price, because a block wall faces weather on both sides and its design and workmanship decide how it holds up. I'll write that plan out at the estimate.
Why should I get a permit for a block wall in San Jose?
A permit protects your home's value and your coverage. The city points out that state law requires sellers to disclose unpermitted work, and insurance generally won't cover damage related to it. When your wall needs one, we apply and meet the inspector, as described above.
What causes white streaks on a concrete block wall?
That's usually a deposit of salts that comes to the surface of the block. It can spoil the look, but it doesn't affect how the wall performs structurally. If you're unsure whether that's all it is, send me a photo and I'll tell you plainly what I see.
How do I keep water from building up behind a block retaining wall?
Give the water a planned way out, because a block retaining wall needs drainage so water can't collect behind it. Industry guidance says that where heavy, long rains are expected, a continuous drain along the back may be added to drains through the wall. Ask every builder how water will leave the soil, and I'll show you how we'd handle it on your wall.
How long does a concrete block wall take to build in San Jose?
The schedule turns mostly on permits, because a wall that needs building, planning or grading approval can't start until they're issued. On a retaining wall, industry guidance says soil goes back only after the block has gained enough strength or the wall is braced, and heavy machines stay back from the top by a distance equal to the wall's height, so we need room around the work. I'll walk you through the order at the estimate.
