Local Caulking & Grout Repair in Malibu, CA
Moldy caulk or cracked grout letting water behind the tile? The old stuff comes out and the new stuff goes in so it actually seals.
Black spots that bleach won't touch. A caulk line peeling away from the tub. Grout washing out of the shower floor one gritty grain at a time. Most calls for caulking and grout repair in Malibu start with something that looks cosmetic but is really a water problem.
Caulk and grout are the cheap parts of a tile job, and they're the parts that fail first. When they go, water gets behind the tile, under the tub lip and into the wall. Our fix is to cut out what's failed, clean and dry the joint and put back the right material for that spot.
And if the tile itself is loose or the backer board is soft, we'll tell you up front instead of caulking over it.
When Caulking and Grout Repair in Malibu Makes Sense
Mold under the caulk line
If the black is under the caulk, not on top, no cleaner will reach it. The caulk has to come out.
Caulk pulling away from the tub
A gap between tub and wall lets shower water run straight behind the surround. That's how subfloors rot.
Cracked or missing shower grout
Gaps in grout let water soak into the backer behind the tile. Small cracks spread fast once water finds them.
Floor grout turning to sand
Grout that crumbles underfoot was usually mixed too wet, or it's been soaking for years.
Dried-out caulk at windows
Cracked exterior caulk at trim and frames lets rain in when wind drives it sideways.
Open seam at the backsplash
Water sits in that counter-to-wall seam every time you wipe down. Left open, it swells the particleboard underneath.
Caulking and Grout Repair for Homes and Rentals
Homes
Tubs, showers, kitchen backsplashes, tile floors and the outside seams around windows and doors. Most homes have a few of each that need attention, so we usually knock them out in one visit.
Rentals & small business
Rental turnovers are a big one. A clean white caulk line and fresh grout make a tired bathroom look cared for. Landlords and property managers call us for small batches (a unit or two at a time, or one office restroom).
Our Approach to Caulking & Grout Repair
Cut out the old caulk
We slice and pull every bit of the old bead, then scrape and wipe off the residue. New caulk won't stick to old silicone. Period.
Grind out bad grout
Failed joints come out with a grout saw or an oscillating tool, deep enough for new grout to lock in. Then we vacuum the joints clean.
Dry it, then fill
Wet joints are the main reason redone caulk fails. So we let things dry, pack in fresh grout and run 100% silicone at the tub and every inside corner.
Seal and wait
Cement grout gets a penetrating sealer once it's cured. We'll tell you how long to keep the shower dry, usually about a day.
The Hard Version: Soft Walls, Loose Tile and Epoxy Grout
Sometimes the grout is just the messenger. Push on the tile near the bottom of the shower. Flex or a hollow sound means water has already gotten behind it, and fresh grout won't fix a wet backer board.
We can reset a few loose tiles and regrout around them when the wall behind is still firm. If it's soft or moldy over a bigger area, the shower needs to come apart. That's tear-out and rebuild work, and we'd rather tell you now than sell you a grout job that fails by summer.
Epoxy grout is the other tricky one. It's tougher and shrugs off stains, but it sets fast and is unforgiving to work, so it costs more. It earns its keep on a shower floor that's already been regrouted twice. For most walls, a good cement grout with sealer does fine.
Moldy tub caulk, crumbling shower grout and leaky window seams cut out and redone right. Send a photo and the address, and you'll get a straight answer.
(333) 333‑3333What's Different About Caulking and Grout Repair in Malibu
Malibu has a lot of older bathrooms. About 60% of the city's housing units were built before 1980, with a median build year of 1976. Showers from that era might have tile over drywall or a thick mortar bed that has held up fine but is cracking at the corners. Which one you have decides the repair, so we check first.
Outside, it's wind-driven rain and sun. The City lists design factors of a 94 mph wind speed and 2.0 inches per hour of rainfall, which tells you how hard a storm can push water at a window frame. Cheap acrylic caulk dries out and cracks in coastal sun. For exterior seams we use urethane or a hybrid sealant that stays flexible, with backer rod in deep gaps.
Can You Recaulk or Regrout It Yourself?
Recaulking a tub is one of the best DIY jobs out there. The trick is all prep: get every scrap of old caulk off, wipe with rubbing alcohol, let it dry overnight and use a 100% silicone made for kitchens and baths. Tape both edges if you don't trust your hand.
Regrouting is harder. Digging out old grout without chipping tile edges takes patience and the right blade, and a whole shower means hours on your knees. A few bad joints? Go for it. A full shower with soft spots behind the tile is a different conversation.
What We Take On and When a Licensed Partner Steps In
We do caulk and grout jobs ourselves because they fit inside California's minor work rule: a total price under $1,000 for labor and materials combined, with no building permit involved. That covers recaulking, regrouting, sealing and resetting a handful of loose tiles.
A new shower pan, re-tiling a whole surround or fixing a rotted subfloor isn't that. Those jobs are bigger, may need permits and can't be broken into smaller bills to dodge the rule. Those go to one of our trusted licensed partners, and we stay your first call while they work.
What to Expect
- How long does it take?
- Recaulking a tub or shower is an hour or two of work plus cure time. Regrouting a full shower is usually a day, sometimes split across two visits when the old grout fights us.
- Will there be a mess?
- Grout removal is dusty. Plastic goes up over the doorway, a shop vac with a fine filter runs the whole time, and the tub and fixtures get wiped down before we leave.
- What does it cost?
- Cost guides put regrouting at $5 to $28 per square foot, and caulking and sealing a shower's corners and edges at $65 to $300 as an add-on to a regrout. Tile size, joint width, stubborn old grout and loose tiles move the number.
- Do I need a permit?
- No for regular caulk and grout work. The City of Malibu treats cosmetic upgrades like floor tile as permit-free. A new shower pan or plumbing changes that.
- Do I need to be home?
- Someone should let us in and see the before. After that you can head out. We'll text when it's done and remind you how long to keep water off it.
Caulking & Grout Repair FAQ
Is caulking and grout repair in Malibu worth it for an old shower?
Usually, yes, as long as the tile is solid. Fresh grout and caulk can add years to a shower that's still sound behind the tile. The test is simple: press on tiles near the floor and corners. If nothing moves and nothing sounds hollow, a regrout makes sense. If tiles flex, the wall behind is wet and needs a bigger repair first.
Why does my new caulk keep turning black?
Usually because the old caulk or mold wasn't fully removed, or the joint was wet when it got caulked. Mold grows from underneath, so new caulk over old spores darkens fast. Poor airflow adds to it. Run the bath fan during and after showers, and squeegee the walls when you can.
Sanded or unsanded grout?
It depends on joint width. Sanded grout is for wider joints, roughly an eighth of an inch and up, because the sand keeps it from shrinking and cracking. Unsanded is for tight joints and polished stone that sand could scratch. We match what's there unless it was the wrong choice to begin with.
Should the corners get grout or caulk?
Caulk. Inside corners and the joint where tile meets the tub should get a flexible bead, not grout. Those spots move a little as the house shifts and the tub fills with water. Grout is rigid and cracks there. A 100% silicone bead handles that movement and keeps water out.
Can you just put new caulk over the old?
No, and we won't do it. New caulk doesn't bond to old silicone, so it peels within weeks and traps mold underneath. The old bead has to come out completely and the joint has to be clean and dry. It's the boring part, but it's really the whole job.
