What's included
What Our Concrete Patio Repair Includes
Every repair starts with a full inspection and a written scope, so you know exactly what is covered before we pick up a tool. Here is what comes standard on a La Jolla Concrete Services patio repair.
Full Slab Inspection
We tap the entire slab for hollow spots, check the grade with a level, and look at where water is draining. You get a written report of what we found and what we recommend fixing now versus watching.
Crack Routing and Filling
We do not just smear sealant over a crack. We route it open with a concrete saw, clean out the debris, and fill it with a flexible polyurethane sealant that moves with the slab instead of cracking again.
Section Cut-Out and Re-Pour
Failed sections get cut out square, the base gets re-compacted, and new concrete goes in with rebar or wire mesh tied into the existing slab. The new section is finished to match the surrounding surface.
Leveling and Trip-Hazard Grinding
Sunken or raised slabs get leveled or ground down so the surface is flat and safe. We check the whole patio for trip hazards, not just the spot you called about, and fix them in the same visit.
Joint Cleaning and Re-Sealing
Open expansion joints are how water gets under a slab. We clean them out and re-seal with a proper joint sealant, then re-cut any control joints that have filled in with debris.
Surface Sealer Application
Once the repair is cured, we apply a penetrating sealer that slows salt and moisture intrusion. This is what keeps La Jolla's marine air from eating the surface and starting the spalling cycle again.
Service overview
What Concrete Patio Repair in La Jolla, California Involves
Concrete patio repair in La Jolla, California is the process of restoring a damaged slab instead of tearing it out: routing and filling cracks, grinding high spots, re-leveling settled sections, patching spalled surfaces, and re-sealing joints so water stops getting underneath. We cut out failed sections with a concrete saw, tie new material into the existing slab with rebar or wire mesh, and match the finish so the patch disappears. Most repairs use a portland cement-based mix or a Rapid Set patch when we need the patio walkable the same day.
La Jolla patios take a specific beating. Marine air, salt fog, and winter rain push moisture into hairline cracks, then the sun dries the surface fast and the slab moves. Add tree roots in older Bird Rock and Windansea Beach yards and you get the cracked patio repair La Jolla homeowners call us for every spring. If your patio has a low spot that holds water or a slab that has dropped an inch at the edge, that is the point where a $400 patch beats a $9,000 replacement.
The service timeline
How Our Patio Repair Process Works
The process flexes to the condition, but these checkpoints keep decisions clear.
Call and Diagnosis
You call, we ask what you are seeing: cracks, a sunken corner, flaking surface, water pooling. We schedule a visit, usually same-day or next-day. On site we tap the slab with a hammer to find hollow spots, check the grade with a level, and look at where water is draining. You get a written scope and a fixed price before we start.
Prep and Cut-Out
We set up containment and protect landscaping. Using a concrete saw with a diamond blade, we cut clean, square edges around every failed section, then break out the bad concrete with a chipping hammer. Edges get squared so the patch keys in mechanically instead of just sitting on top. This step takes two to four hours on a typical patio.
Sub-Base and Reinforcement
We dig out loose soil and any root intrusion, then compact a fresh aggregate base in lifts. Where the slab needs structure, we tie in rebar or wire mesh and drill dowels into the existing concrete with Simpson Strong-Tie epoxy. This is what keeps the repair from cracking along the seam six months later.
Pour, Finish, and Match
We mix the patch to match the existing slab, place it, and consolidate it with a vibrator to kill air pockets. A screed and bull float bring it level, then we finish with a broom, float, or stamp to match the original texture. Expansion joints get re-cut with a groover so the slab can still move with the seasons.
Cure, Seal, and Walkthrough
Fresh concrete cures for 24 to 48 hours before foot traffic and seven days before heavy loads. We apply a penetrating sealer once the surface is dry, which slows salt and moisture intrusion. Then we walk the job with you, show you the repair, and leave you with simple care instructions.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Concrete Saw
Cuts clean, square edges around failed sections so the patch keys in mechanically. A diamond blade cuts through rebar and old aggregate without shattering the surrounding slab.
Bull Float and Power Trowel
Levels and finishes the new concrete so it matches the existing surface. The bull float pushes the cream to the surface; the power trowel gives a hard, smooth finish on larger patches.
Rebar Cutter and Bender
Cuts and shapes rebar to tie new sections into the existing slab. Properly tied reinforcement is what keeps the repair from separating along the seam.
Concrete Vibrator
Consolidates the new mix and drives out air pockets that would otherwise become weak spots. We use it on every pour thicker than four inches.
Groover and Edger
Cuts control joints and rounds the edges of the new section. Control joints give the slab a place to crack on purpose so it does not crack where you do not want it.
Screed
Strikes off the excess concrete and brings the surface to grade. A straight screed is what makes the patch sit flush with the surrounding slab.
Wheelbarrow and Concrete Mixer
Mixes and moves small batches of concrete to the repair site without tearing up the yard. On larger repairs we bring in a truck, but for patches a mixer gives us better control of the mix.
Use cases
When to Call for Patio Repair
These examples show how the service framework adapts rather than forcing every call through one repair.

Windansea Beach Spalling Repaired
An exposed aggregate patio near Windansea Beach had spalled across about 200 square feet. The top layer was flaking off, leaving a rough surface that was uncomfortable to walk on and getting worse each winter from salt air. → We removed the loose material, applied a polymer-modified overlay, and re-exposed the aggregate to match the original finish. Then we sealed the whole patio. The repair cost $2,100 and the patio has held through two winters.
La Jolla Shores Settled Slab Leveled
A patio in La Jolla Shores had settled about an inch and a half at one corner, creating a trip hazard and a low spot that held water. The soil underneath was soft from poor drainage, and the slab was rocking slightly when walked on. → We cut out the settled section, dug out the soft soil, and rebuilt the base with compacted aggregate. New concrete went in with dowels tying it to the stable section. The patio is now level, drains properly, and the trip hazard is gone.
Problems we solve
Patio Problems We Fix in La Jolla
Most patio calls we get fall into a handful of categories. Here are the ones we see most, what happens if you leave them, and how we fix them.
Cracks running across the slab
We route the crack open, clean it, and fill it with flexible sealant. If the slab has moved, we cut out the failed section, re-compact the base, and re-pour with rebar tied into the existing concrete.
Sunken or uneven slab sections
We lift and re-level the section or cut it out and re-pour on a properly compacted base. We re-establish the grade so water runs away from the house, not toward it.
Spalling and flaking surface
We remove the loose material, patch the surface with a polymer-modified repair mortar, and apply a penetrating sealer. On badly spalled patios we can resurface the whole slab instead of replacing it.
Efflorescence and white staining
We clean the efflorescence, find the moisture source, and seal the slab. If the source is a drainage problem, we fix the grade so water stops getting under the patio in the first place.
Pricing process
What Patio Repair Costs in La Jolla
$350 - $2,500 depending on scope
Size of the repair area
Small crack fills are quick and cheap. A section replacement covering 50 square feet takes more material, more labor, and more time. We measure the actual repair area, not the whole patio, so you only pay for what needs fixing.
Depth of the damage
A surface crack is a one-hour fix. A crack that goes through the slab and into a failed base means cutting out, re-compacting, and re-pouring. The deeper the problem, the more the repair costs, but the longer it lasts.
Base and sub-grade condition
If the soil under the slab has settled or washed out, we have to fix that before we pour. Base repair adds cost but it is the only way to stop the slab from moving again. Skipping it is why cheap patches fail.
Customer reviews
What La Jolla Homeowners Say
“We had a 20-foot crack running through our back patio and water was pooling against the house every time it rained. La Jolla Concrete Services cut out the bad section, fixed the base, and re-poured it in one day. The patch matches the old broom finish so well that guests do not notice it. Fair price, clean job, no mess left behind.”
“Our exposed aggregate patio had spalled badly near the pool, and we were quoted a full replacement by two other companies. These guys patched and re-sealed it for a fraction of that. They matched the aggregate and the color, and it has held through two winters now. Honest assessment instead of an upsell.”
“We manage several rental properties and had a trip-hazard slab at one of them that needed fixing fast. They came out the same day, ground down the high edge, and patched the crack. Tenants were able to use the patio that evening. I have used them on three more properties since.”
How much does concrete patio repair cost in La Jolla California?
Most repairs run $350 to $1,800 in 2026, with small crack fills starting around $250 and larger section replacements reaching $2,500. The cost to repair concrete patio in La Jolla California depends on square footage, crack depth, whether the sub-base needs work, and finish matching. We give you a fixed price before we start, so the number you hear is the number you pay.
Can I repair a cracked concrete patio myself in La Jolla?
You can fill a hairline crack with a tube of polyurethane sealant, and that is fine for cosmetics. But if the slab has moved, if one side of the crack is higher than the other, or if the crack is wider than a quarter inch, a DIY patch will fail within a season. That is when you want a patio repair contractor La Jolla CA who can address the sub-base, not just the surface.
What causes concrete patios to crack in La Jolla?
The main causes here are soil movement, tree roots, poor original drainage, and salt air working on the surface. La Jolla sits on a mix of clay and fill, and when that soil gets wet then dries, the slab moves and cracks. Freeze-thaw is rare here, but the marine layer keeps concrete damp long enough for efflorescence and spalling to start. Fixing the water path is the real cure.
