Concrete Contractor in Westmont, CA - Driveways and Patios That Drain Right
H&J Gardena Concrete Contractors builds and replaces concrete driveways, patios, walks and slabs in Westmont, with a packed base under the pour and water running away from your house.

How concrete jobs go in Westmont
Westmont is a Los Angeles County community, not its own city, and it's nearly all houses, street after street, with very little empty land left. So most of our calls here are about concrete that's already down, like a driveway that's dropped toward the garage, a walk lifted by a tree root or a cracked backyard slab someone wants turned into a real patio. It's the same kind of work we do in West Rancho Dominguez and Hawthorne, on lots where the side yard is narrow and the neighbor's fence is close.
Because it's County ground, building permits here come from LA County Public Works, and you can check which office covers your address with the County's Find Services lookup. We check it too, and when your job needs a permit, we pull it and line up the inspections before we pour. The price mostly moves with the size of the slab, how much old concrete has to come out, what the base needs and how hard it is to get a truck to the spot. The schedule turns on the permit, if there is one, and on curing, the days new concrete needs to harden before you walk or drive on it. I measure all of that at the estimate and put the work in writing. On streets this built out, getting the old slab out and the new concrete in is often a bigger part of the job than the pour itself.
What we pour and fix in Westmont
Concrete driveway building
Most Westmont driveways we see are older and narrow, so we break out the cracked slab, rebuild the base and pour one that drains toward the street.
Concrete patio construction
Backyards here are small, so a new patio often covers much of the yard, and we pitch it away from the back door so rain doesn't run inside.
Stamped concrete services
Stamped concrete gives a small Westmont front yard some pattern and color. We set the joints along the pattern lines, where cracks are harder to spot.
Concrete sidewalk building
Tree roots lift a lot of walks in these neighborhoods. We cut out the raised panels and pour new ones level with the rest.
Garage floor concrete
Older detached garages here often have thin, cracked floors that settled years ago. We break them out and pour a new garage floor that sheds water to the door.
Decorative concrete
Colored and textured finishes suit the porches and front walks on Westmont's older homes, and we match the look to what's already on the house.
Concrete retaining walls
Where a yard drops to a driveway or the next lot, a retaining wall holds the soil back, and we drain behind it so water can't build up.
Concrete floor installation
For a room addition or a converted garage on a small lot, we pour the interior floor level and ready for whatever flooring goes on top.
Concrete pool decks
Where a Westmont backyard has a pool, the deck usually runs to the fence. We give the pool deck a broom finish, a light texture that helps wet feet grip.
Concrete steps construction
Front steps on older houses here tend to pull away from the porch as the ground settles. We rebuild the steps on a footing dug down to firm ground.
Slab foundation building
Adding a unit out back or a room to the house? We pour the slab foundation once the ground is dug out, packed and checked.
Foundation installation
On a tight Westmont lot, a new foundation often goes in close to the neighbor's fence, so we plan the dig and the pour around that access.
Concrete parking lot building
Small apartment buildings and shops along the main streets need parking that drains and holds up to daily cars, so we start with the slope and the base.
Concrete footings
Block walls, patio covers and porch posts all need footings, the concrete pads buried under them, and we dig them to firm soil rather than loose fill.
Foundation raising
When an older house here has a corner that's dropped, doors stick and floors slope. We look at why it settled before we talk about raising the foundation.
Concrete cutting
Making room for a new sewer line or a wider driveway on a lot this tight usually means cutting the old slab cleanly, so the rest stays whole.
Is your Westmont driveway or patio due for work?
Most of the concrete around Westmont houses has been down a long time, so these are worth a look before a small problem turns into a tear-out.
- Cracks that keep getting wider
- Slab sinking toward the garage
- Water pooling by the house
- Chipping or a dusty surface
- Lifted edge on the walk
- Steps pulling away from the porch
If you see one of these, call (424) 528-1322 or send the form, and I'll come look and tell you plainly what's causing it.
Patch the old slab or pour a new one?
On older Westmont concrete, the choice comes down to what's under it. If the base held, a repair usually works, and if the ground moved, a patch usually doesn't hold.
When a repair is enough
A few hairline cracks, a chipped corner or one sunken panel on an otherwise solid slab can usually be fixed. We cut out and replace the bad section, or seal the cracks, and leave the rest of your driveway alone.
When it's time to replace
When cracks run across most of the slab, water pools against the house, or the whole thing has dropped, the problem is usually the base underneath. Patching the top won't fix that, so we break it out, dig and pack the base, and pour new.
What Westmont lots ask of new concrete
I started this business in Gardena in 2017, and I still come out to look at each job myself and work alongside our crew when it's poured. Your satisfaction, guaranteed.
Base before finish
If the budget's tight, I'd trim the finish before the base, because a raked-flat base settles with the dirt.
Slopes away from your house
We check where water runs before we set forms, so the slab slopes away from your house instead of toward it.
Joints cut on time
Control joints are grooves that tell the slab where to crack, and we cut them early so cracks land in them.
The hard news up front
If your job needs a new base or drainage work, I'll tell you at the estimate instead of a year later.
