The first thing we ask on a chimney repair call is where the water is getting in. Almost every masonry problem, from crumbling mortar to stained ceilings to rusted dampers, starts with moisture. San Diego's rain comes mostly between December and March, so damage tends to advance in bursts, one wet season at a time.

We trace the leak or crack back to its source, which may be a split crown, gaps in the flashing where the chimney meets the roof, or open mortar joints, and repair that part properly. A missing chimney cap is often part of the story. If the inside of the flue is in question, a camera inspection comes first.

Chimney repairs we handle

Each repair targets the part that failed, with the materials the chimney was built from.

Crown repair & rebuild

Hairline cracks sealed; crowns that are broken through or sloped the wrong way rebuilt so water runs off the top instead of soaking in.

Mortar joints & brick

Failing joints cut out and repointed, and spalled or loose bricks replaced so the structure stays tight.

Flashing repair

The seal between chimney and roof re-flashed where it has pulled away, a common source of the stain on the ceiling below.

Liner repair

Cracked or gapped flue liners found on camera, with repair or relining options explained.

Repair now or wait?

01

Fix it before the rain

Open joints, a cracked crown or loose flashing let water in every storm. These are cheaper to fix early than after a season of freeze-free but steady soaking.

02

Don't use it until it's fixed

Liner cracks, gaps or damage from a chimney fire let heat and gases reach places they shouldn't. Repair comes before the next fire.

Signs your chimney needs repair

Masonry usually warns you before it fails. Look for:

  • Stains on the ceiling or wallWater following the chimney into the house.
  • White staining on the brickMinerals left behind as water moves through the masonry.
  • Gaps or crumbling mortarJoints you can scratch out with a key need repointing.
  • Cracked or chipped crownVisible from the roof or in a photo taken from the ground with a zoom lens.
  • Rust on the damper or fireboxWater is getting down the flue.

Safety first. Don't stand on or lean ladders against a chimney with loose brick, and keep people away from the area below it. After any strong earthquake, have the chimney checked before you use it.

How we approach chimney repair

Diagnosis before demolition

We confirm where water or damage comes from so you don't pay to fix the wrong thing.

Matched materials

Mortar and masonry suited to the chimney you have, not a quick patch that pops out next winter.

Line-item estimate

Each part of the repair priced separately, so you can see what's urgent and what can wait.

Cap and crown as a system

We look at how the top of the chimney sheds water, because that's where most leaks begin.

FAQs

Chimney Repair FAQs

Why is my chimney leaking?

The usual suspects are a cracked crown, flashing that has separated from the roof, porous or open mortar joints, or a missing cap letting rain fall straight down the flue. Often it's two of these at once. We find the actual entry point before quoting a repair.

How much does chimney repair cost?

It ranges widely: sealing a hairline crack in a crown is a small job, while rebuilding a crown or repointing a whole chimney is much bigger. Roof access and height matter too. You get an itemized written price after we've seen it.

Can a cracked chimney crown be repaired, or does it need replacing?

Fine cracks in an otherwise solid crown can usually be sealed. A crown that's broken through, crumbling or built without enough slope or overhang usually needs to be rebuilt to stop the water for good.

Do you repair chimneys after an earthquake?

Yes. CSIA recommends a Level 2 inspection after a seismic event, because cracks inside the flue aren't visible from the room. We start there and repair whatever the inspection finds.

Will waterproofing fix a leaking chimney?

Only if the masonry itself is soaking up water and everything else is sound. Sealer won't fix a cracked crown, missing flashing or open joints, so those get repaired first.
