Chimney Masonry Work in La Canada Flintridge and Nearby Towns

What does chimney tuckpointing involve?

Tuckpointing means grinding out worn mortar and packing fresh mortar into the joints. We match the new mortar to the old for color and hardness, because mortar harder than the brick can crack the brick faces. Open joints, sandy grit on the roof, or a gap you can push a key into all point to it.

How can I tell if my chimney crown is cracked?

Crown cracks usually show from the roof as hairline lines running out from the flue or across the corners. Inside the house, a water stain at the top of the firebox or rust on the damper can point to the same problem. We photograph the crown on every roof visit so you can see it for yourself.

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

A crown with hairline cracks can usually be sealed. A crown that is broken through, crumbling, or poured flat with no slope needs to be recast. We also check for a drip edge, the overhang that keeps rain off the brick faces below the crown.

Why does my chimney leak when it rains?

The leak usually starts at the flashing, the crown, or the cap. Step flashing and counter flashing seal the joint between roof and brick, and a gap there sends water into the attic and down the walls. We trace the leak to its entry point before we repair anything.

What is the difference between a partial and a full chimney rebuild?

A partial rebuild takes the chimney down to sound brick, often at or just above the roofline, and lays it back up. A full rebuild replaces the stack from the firebox or the foundation. Which one you need depends on where the brick and mortar stop being sound, and the photos show that line.

Do I need a spark arrestor cap in La Canada Flintridge?

Yes, we put spark arrestor mesh on every wood-burning flue we cap here. The 2009 Station Fire burned within La Canada Flintridge city limits, and embers leaving a flue can reach a roof or dry brush. The same cap keeps rain, leaves and animals out of the flue.

How long does chimney masonry repair take?

A crown seal or cap replacement usually takes part of one day. Tuckpointing a full chimney can take two to three days, depending on height and access. A rebuild above the roof takes longer, and a steep lot may need scaffolding set first. The written scope lists the expected days.

Will the repair match my existing brick and mortar?

Yes, we match mortar color and joint profile to what is already there, and source brick as close to the original as we can find. When a section comes down on an older chimney, we reuse the sound brick from that same stack.

Should I book an inspection before masonry work?

Yes, the inspection comes first. It shows whether the problem sits at the crown, the flashing, the joints or inside the flue, so the repair fixes the cause and not only the symptom. A sweep in the same visit gives the camera a clean look at the flue liner.

What can an earthquake do to a brick chimney?

Shaking can crack the crown, open mortar joints near the roofline, or shift the top courses of brick. Check it before you light the next fire. From the ground, look for a lean, missing mortar, or brick pieces on the roof, then have the top inspected and photographed.
