What Our Patio Repair Service Includes
Every repair starts with a full slab assessment and ends with a walkthrough. The inclusions below are standard on our patio repair jobs. If your patio needs a full re-pour or a decorative finish change, we quote that separately and you decide before we start.
Crack Routing and Cleaning
Cracks are opened with a concrete saw to a uniform width, then vacuumed and cleaned so the filler bonds to sound concrete. This step is what separates a repair that lasts from a patch that pops out in a season.
Slab Lifting Where Needed
Settled sections get raised back to grade with mudjacking or foam lifting, so we are not just hiding a low spot with filler. The slab goes back to correct slope and drainage without a tear-out.
Color and Texture Matching
Patched areas are floated, edged and finished to blend with the surrounding slab. On stamped or stained patios we match pattern and color as closely as the existing finish allows, then blend the repair into the whole surface.
Sealing and Protection
Once cured, the repaired area or the full slab gets a concrete sealer that blocks water and UV. Sealing is what keeps a repair looking right and stops new cracks from forming at the edges of the patch.
Site Cleanup and Walkthrough
We haul off debris, wash down the area, and walk the finished patio with you. You see exactly what was repaired, get told what to watch for, and receive the workmanship warranty in writing.
What Concrete Patio Repair in Clairemont, California Involves
Concrete Patio Repair in Clairemont, California is the process of restoring a damaged slab instead of replacing it: routing and filling cracks, grinding down uneven edges, correcting poor drainage, and re-sealing the surface so water stops getting in. We start by reading the slab. A crack that runs straight through a control joint is usually cosmetic. A crack that steps up or down, or one that keeps reopening after patching, points to settling underneath. That distinction decides whether you get a $300 repair or a $3,000 partial re-pour.
Clairemont patios take a specific beating. Summer sun pushes surface temps past 140 degrees, then marine layer moisture rolls in overnight, and that swing works on every joint and crack. Older slabs poured in the 1960s and 70s around Mount Streets and Clairemont Village often sit on shallow footings with no rebar, so they move. If you have been searching patio crack repair near me Clairemont and getting thin answers, the real question is whether your slab is settling or just aging. We answer that on site, usually in under 30 minutes.

Tools and Methods We Use
Tools & Equipment
Concrete Saw
Used to route cracks to a uniform width and cut clean control joints. A proper saw cut is what lets the filler bond to sound concrete instead of sitting on top of a ragged edge.
Laser Level
Checks slab slope and grade before and after lifting. We use it to confirm water will run away from the house, not toward it, which is the most common drainage problem we find on Clairemont patios.
Concrete Mixer and Screed
For patch mixes and small pours, we batch and place material on site, then screed it to the surrounding grade. This keeps the repair level with the existing slab instead of leaving a hump or dip.
Power Trowel and Edger
Finishes patched and poured areas to a hard, smooth surface and cleans up the edges. A properly edged repair blends into the existing slab and does not chip at the border.
Groover
Re-cuts control joints where the originals have failed or were never placed. Joints give the slab a place to crack on purpose, which keeps random cracks from forming across the surface.
Concrete Pump
Reaches backyard patios where a wheelbarrow cannot go. Common in Clairemont yards with narrow side access, and it keeps the pour continuous so there are no cold joints in the repair.
Methods & Standards
Crack Routing and Polyurethane Injection
We open the crack with a concrete saw, clean it, and inject a flexible polyurethane or epoxy filler. Flexible fillers move with the slab through temperature swings, which is why they outlast rigid patching on Clairemont patios that see hot days and cool nights.
Mudjacking and Foam Lifting
Settled slabs get raised by pumping a cement slurry or expanding foam underneath. The slab goes back to grade without a tear-out, and the process typically takes a few hours per section with no curing wait before light use.
Polymer-Modified Overlay
For worn or spalled surfaces that are still structurally sound, we apply a polymer-modified overlay bonded to a properly prepped slab. It restores a smooth finish and can be stamped or stained to change the look.
Sealing to ACI and C-8 Standards
We apply breathable concrete sealer to repaired areas and full slabs, following ACI guidance on cure time and surface prep. Sealing blocks water and UV, and it is the single cheapest step to extend the life of a repair.
When to Call for Patio Repair
01
A Clairemont homeowner notices a crack that has grown from hairline to a quarter inch over one summer.
What we do: We route the crack, clean it out, and fill with a flexible polyurethane sealer that moves with the slab. If the crack shows vertical displacement, we check the base and lift the section back to grade before filling.
→ The crack stops widening, water stops getting in, and the repair blends into the surrounding slab. Most jobs like this are done in a single visit.
02
A patio slopes toward the house and puddles after every rain, and the owner is worried about the foundation.
What we do: We assess the slope with a laser level, lift any settled sections, and re-grade the surface or add a channel drain so water leaves the patio. We check the foundation edge at the same time.
→ Water runs away from the house instead of sitting against it, and the patio drains dry within an hour of a storm.
03
A stamped patio has a cracked and discolored section that ruins the look of the whole yard.
What we do: We repair the crack, match the stamp pattern and color as closely as the existing finish allows, then seal the full slab so the repair blends in and the color holds.
→ The patch reads as part of the original patio, and the resealed surface resists staining and UV fade for years.
04
A homeowner is preparing to sell and needs the patio repaired before listing photos and inspections.
What we do: We prioritize pre-sale repairs, handle cracks, trip hazards and drainage in one visit where possible, and provide a written scope and warranty the buyer's agent can review.
→ The patio passes inspection, photos show a clean surface, and the repair paperwork supports the sale.
How Patio Repair Runs in Clairemont
Clairemont sits close enough to the coast to get marine layer moisture most mornings, then heats up fast by afternoon. That daily swing is hard on concrete. Slabs poured in the 1960s and 70s around Mount Streets and Clairemont Village often have no rebar or wire mesh, so they move with the soil and crack at the corners. We also see a lot of patios built on fill dirt, which settles unevenly and leaves low spots that hold water. Our approach is to fix the cause first: correct the grade, lift the settled section, then repair the surface. If you have been searching for patio crack repair Clairemont California and getting quotes that only mention filler, ask what they are doing about drainage and base movement. That is the difference between a repair that lasts five years and one that fails by next spring. We work to California C-8 standards and pull permits where the scope requires it.
Neighborhoods We Serve
-
Clairemont Mesa
Larger lots with older slabs, many poured without rebar. Settling at patio edges is common here, and we often lift sections back to grade rather than replace them.
-
Bay Park
Closer to the water, so marine moisture and salt air accelerate surface scaling. We spec sealers with better UV and moisture resistance on patios in this area.
-
North Clairemont
Sloped yards mean patios often sit behind retaining walls. When a wall leans, the patio above it moves, so we check both before quoting a repair.
-
Mount Streets
Mid-century homes with original concrete patios. Cracks here are usually from age and missing control joints rather than new settling, so routing and joint work solves most of it.
-
Clairemont Village
Tighter lots and narrow side access. We use a concrete pump or smaller equipment to reach backyard patios without tearing up landscaping.
Local Conditions We Plan For
-
Daily temperature swings from marine layer to afternoon sun
Concrete expands and contracts every day, which opens joints and works cracks wider over time. Flexible fillers and correctly placed control joints are what absorb that movement.
-
Expansive clay soil in parts of Clairemont
Clay swells when wet and shrinks when dry, lifting and dropping slabs. This is the leading cause of settled patio sections, and it is why we check the base before patching a surface crack.
-
Older slabs poured without rebar or wire mesh
Unreinforced slabs crack more easily and lose sections at the edges. Where the slab is otherwise sound, we repair and seal it. Where it is failing structurally, we recommend a re-pour.
-
Winter rain concentrated in a few heavy storms
Water finds every crack and joint in a short window. Fall is the right time to repair and seal, so the slab is protected before the first big storm hits.

Patio Problems We Solve in Clairemont
Most patio calls come down to four issues. Here is what each one does if you leave it, and how we fix it.
Problem
Cracks that keep reopening after DIY patching
Water keeps reaching the subgrade, the crack widens each season, and eventually the slab edge breaks off entirely. A crack that has reopened twice is a sign the cause was never addressed.
Our Fix
We diagnose why the crack is moving, whether that is settling, a missing control joint or thermal movement, then route and fill with a flexible material matched to that cause. Fixing the reason is what stops the crack from returning.
Problem
Sunken or uneven patio sections
Low spots hold water against the house, which pushes moisture into the foundation. Uneven slabs also create trip hazards, especially at the transition to a walkway or step.
Our Fix
We lift the settled section back to grade using mudjacking or foam injection, then check the whole patio with a laser level so drainage runs away from the house. No tear-out, and you can use the patio the next day.
Problem
Spalling and surface scaling
Once the top layer starts flaking, freeze-thaw and foot traffic accelerate it. The surface turns rough, collects dirt and looks worn out within a couple of seasons.
Our Fix
We remove the loose material, repair the surface with a polymer-modified patch or overlay, and seal it. That restores a smooth, weather-resistant finish and stops the scaling from spreading across the slab.
Problem
Efflorescence and white staining
The chalky white deposits are salts pushed to the surface by moisture moving through the concrete. It looks bad and it signals that water is getting into the slab from somewhere.
Our Fix
We clean the deposits, find the moisture source, and correct the drainage or sealing issue causing it. Then we apply a breathable sealer so moisture can escape without carrying salts to the surface again.
Why Fix the Patio Instead of Replacing It
A full tear-out and re-pour runs three to five times the cost of a targeted repair, and it means a torn-up yard for a week. Here is what a proper repair buys you in Clairemont.
-
Stop the Crack Spreading
Water is what turns a hairline crack into a structural one. Once moisture reaches the subgrade and we get a cool night, that water expands and pushes the slab apart. We route the crack to a uniform width, clean it out, and fill it with a flexible polyurethane or epoxy sealer that moves with the slab instead of cracking again next season.
-
Kill the Trip Hazard
A lifted slab edge of half an inch is enough to catch a shoe. We grind or mudjack those lips flat, then check the whole patio with a laser level so you are not trading one hazard for another. Most trip-hazard repairs are finished in a single visit and you can walk on the surface the same day.
-
Fix Drainage Before Winter
Clairemont patios that slope toward the house or hold a puddle after rain are feeding water into the foundation. We re-grade the surface or add a channel drain so water leaves the slab. Catching this in fall costs a fraction of what foundation repair costs after a wet January.
-
Protect the Finish You Paid For
If your patio is stamped or stained, cracks and efflorescence ruin the look fast. We match the existing color and texture as closely as the material allows, then apply a concrete sealer to lock it in. A resealed patio in Clairemont typically holds its appearance for three to five years before it needs another coat.
What Patio Repair Costs in Clairemont
Typical 2026 pricing for patio repair in Clairemont runs $350 to $1,800 for most residential jobs. A single crack routed, filled and sealed sits at the low end. Lifting a settled section, repairing multiple cracks and resealing the full slab sits at the high end. Full re-pours are quoted separately and usually start around $12 to $18 per square foot. We give you a written price on site before any work starts, so there is no surprise on the invoice. If you want a ballpark before we arrive, call and describe the cracks and we can usually narrow the range.
Typical Investment Range
$350 - $1,800 for most residential patio repairs; full re-pours from $12 - $18 per square foot
A targeted repair costs a fraction of a tear-out and re-pour, and it solves the problem in a day instead of a week. Fixing the cause, not just the crack, is what makes the money you spend last.
What changes the price
01
Number and Length of Cracks
Each crack has to be routed, cleaned and filled individually. Five short cracks take longer than one long one, and cracks wider than a quarter inch need more material and sometimes a two-stage fill.
02
Whether the Slab Has Settled
A stable slab with surface cracks is a straightforward repair. A settled slab needs lifting with mudjacking or foam injection first, which adds labor and equipment to the job.
03
Surface Finish Type
Plain gray concrete is the easiest to match. Stamped, stained or exposed aggregate patios take extra time for color and texture matching, which raises the labor cost.
04
Drainage Corrections
If the patio slopes toward the house or holds water, we correct the grade or add a channel drain. That work protects the foundation and is often the most valuable part of the job.
05
Access to the Patio
Backyard patios with narrow side access need a concrete pump or smaller equipment. We factor that into the quote up front rather than adding it later.
06
Sealing Scope
Sealing just the repaired area costs less than sealing the full slab. We recommend the full slab when the surface is chalky or the patio has not been sealed in several years.

Verified Reviews
Google ★★★★★4.9
Called about a crack that had reopened twice. They diagnosed it as settling, lifted the slab and fixed the drainage instead of just patching again. Two years later, still solid. Fair price and they showed up when they said they would.
Yelp ★★★★★4.8
We had three quotes for our stamped patio repair. These guys were the only ones who talked about matching the pattern and color. The finished repair blends in and the resealed patio looks better than it has in years.
BBB ★★★★★4.9
Professional from the estimate to the cleanup. They explained what caused the cracks, gave a written price, and finished in one day. The workmanship warranty was in writing, which none of the other contractors offered.
What Clairemont Neighbors Say
Real experiences from customers who chose our Concrete Patio Repair services.
“Our patio had three cracks that kept coming back after I patched them myself. They routed them out properly, filled with something flexible, and resealed the whole slab. That was two winters ago and nothing has reopened. They also caught that the slab was sloping toward the house and fixed the grade while they were here.”

“One section of our patio had sunk about an inch and a half and water pooled there every time it rained. They lifted it back to grade without tearing anything out and matched the finish so you cannot tell where the work was. Done in a day, and the price was exactly what they quoted.”
D
Dan K.
Homeowner, Bay Park
“We have a stamped patio and I was worried a repair would look like a patch. They matched the pattern and color better than I expected, then sealed the whole thing. The crew was on time, cleaned up after themselves, and walked me through what to watch for. Would call them again without hesitation.”

Frequently Asked Questions About Patio Repair
Real answers to the questions we hear most often from local homeowners and property managers.
How much does concrete patio repair cost in Clairemont?
Most residential repairs in Clairemont run $350 to $1,800 in 2026, depending on crack length, whether the slab has settled, and whether the finish is plain or stamped. A single crack fill and seal is at the low end. Mudjacking a sunken section plus crack repair and resealing sits at the high end. We quote the exact number on site before any work starts.
Can I repair cracks in my concrete patio in Clairemont?
Yes, if the crack is stable and the slab is not settling. Hairline and mid-width cracks can be routed and filled with epoxy or polyurethane and will hold for years. If the crack has vertical displacement, or if the slab sounds hollow when tapped, the base has moved and a surface patch will fail. We check that on site and tell you which one you have.
How long does patio crack repair take in Clairemont California?
A straightforward crack repair and reseal takes two to four hours and you can walk on it the same day. If we are lifting a settled section with foam or mudjacking, plan on a full day plus 24 hours before you put furniture back. Stamped or stained patios needing color matching add another half day for cure time.
What causes concrete patio cracks in Clairemont?
Four things cause almost every crack we see here: soil settling under the slab, poor drainage that lets water pool at the edges, missing or badly placed control joints, and thermal movement from hot days and cool coastal nights. Older Clairemont slabs poured without rebar or wire mesh are the most prone. Fixing the cause is what keeps the crack from returning.
