What chimney repair covers, from the crown down

Chimney damage usually starts where water gets in: the crown and cap at the top, the mortar joints and the flashing where the chimney meets the roof. These are the repairs, from small to large:

  • Crown, cap and flashing

    The crown sheds rain off the top of the chimney, the cap keeps rain, leaves and animals out of the flue, and the flashing seals the joint with the roof. A stain on the ceiling next to the chimney often starts at one of them; see roof repair.

  • Tuck-pointing

    Crumbling mortar is raked out and the joints are refilled with new mortar, so water stays out of the brick and the masonry holds together.

  • Flue liner replacement

    A cracked or missing liner lets heat and smoke reach the brick and the house framing. The Chimney Safety Institute of America notes that stainless steel liners for wood-burning appliances must be insulated, while liners for gas appliances do not need it.

  • Chimney rebuild

    Loose or broken brick, a leaning stack or a failed crown: the damaged part is taken down and rebuilt, above the roofline or, for a full chimney rebuild, from lower down.

  • Interior damage repairs

    Stained or cracked plaster, damaged drywall and wet framing beside the fireplace are repaired once the leak is stopped. Larger leaks are a water damage job.

Chimney Repair Services


As chimney repair contractors, we want to help you prevent the elements from harming your masonry. For instance, as odd as it may seem, water causes more damage to chimney masonry than fire. While the brick and/or other materials that make up the exterior of your home are protected by the roof and eaves, your chimney is completely exposed to the elements; rain, snow, and freeze/thaw cycles.

Chimney Sweeping Inspection and Repair


We’ll Turn Your Ideas into a Reality

What’s more, chimneys are usually constructed from materials that suffer accelerated deterioration as a result of prolonged contact with water. A masonry chimney is constructed of a variety of masonry and metal materials, including brick, mortar, tile, steel and cast iron. These kinds of materials deteriorate quickly when exposed to the freeze/thaw process, in which the moisture that has penetrated the materials periodically freezes and expands, causing undue stress. Water also causes rust in steel and cast iron, weakening or destroying the metal parts of your chimney.

Increase Fire Safety


An unclean chimney is a fire hazard. According to the latest Consumer Products Safety Commission report, chimney fires represent the second-largest share of all residential fires.

Remove Flue Obstructions


The uppermost section of the chimney is the chimney crown. And if the crown does not have a sturdy chimney cap, leaves, twigs, and dirt from nearby trees can blow in the flue. It also allows small animals and rodents to take cover where they often get trapped unable to escape.

Prolong the Life of Your Chimney

Professional chimney cleaning prolongs the life of your chimney. The chimney sweep scrubs the flue liner and the interior walls to remove creosote and other stains from the masonry.

Brick chimneys and earthquakes

A masonry chimney is heavy, rigid and brittle, so in an earthquake it moves differently from the wood-frame house around it. The Federal Alliance for Safe Homes’ Earthquake Strong fact sheet gives two things to know:

  • How to check yours: look for straps, braces or steel brackets tying the chimney to the roof or attic framing, reinforcing steel inside it, and retrofit records or permits.
  • The retrofit: the firebox and chimney are replaced with light-frame construction above the top of the foundation, and the masonry fireplace and mantel give way to a factory-built fireplace unit.

For the house itself, see the earthquake retrofit notes on our foundation repair page.

Signs your chimney needs repair

  • Water

    Stains on the ceiling or wall beside the chimney, rust on the damper, damp brick inside the firebox.

  • Masonry

    Crumbling mortar, chipped or loose bricks, a cracked crown, a stack that leans.

  • Smoke and smell

    Smoke coming into the room, or a strong smell in summer: CSIA traces that odor to creosote deposits in the flue.

  • After a chimney fire

    Warped damper metal, cracked flue tiles, creosote flakes on the roof or ground, smoke escaping through mortar joints. CSIA advises not using the chimney until it is swept and evaluated.

Fireplace rules in Los Angeles to know before a rebuild

South Coast AQMD Rule 445 decides what a rebuilt fireplace can be in the South Coast Air Basin part of the district:

  • What may be installed: a new or used permanently installed wood-burning or gas device may only be an EPA-certified wood-burning heater, a pellet-fueled heater, a masonry heater or a dedicated gas fireplace.
  • Newer homes: no wood-burning device may be permanently installed in a home whose construction began on or after March 9, 2009.
  • No-Burn days: from November through the end of February, the district can declare 24-hour bans on burning wood in fireplaces, stoves and outdoor fire pits. Gas fireplaces are exempt; Check Before You Burn lists the other exemptions.

What sets the cost of chimney repair

  • Height and access

    One or two stories, the roof’s pitch and material, and how the crew can reach the top safely.

  • How much is damaged

    A crown and a few joints, the part above the roofline, or the whole chimney.

  • Liner and fireplace

    The liner type and flue size, and whether the fireplace stays, gets an insert or becomes a factory-built unit.

  • Repairs around it

    Roof flashing and shingles, and the ceilings and walls inside that the water reached.

Chimney repair questions

How often should a chimney be inspected?

At least once a year. NFPA 211, the standard the Chimney Safety Institute of America follows, says chimneys, fireplaces and vents shall be inspected at least once a year for soundness, freedom from deposits and correct clearances, with cleaning and repairs done if necessary. CSIA applies this to gas furnace and fireplace chimneys too.

Should a damaged brick chimney be repaired, rebuilt or replaced?

It depends on how much of it is sound. Crumbling mortar and a cracked crown on a solid chimney are repaired; loose or broken brick is taken down and rebuilt. For an old brick chimney in earthquake country, the Federal Alliance for Safe Homes also describes replacing the firebox and chimney with light-frame construction and a factory-built fireplace.

Can I still burn wood in my fireplace in Los Angeles?

Yes, except on No-Burn days. From November through the end of February, South Coast AQMD can declare 24-hour bans on burning wood in fireplaces, stoves and outdoor fire pits when fine-particle pollution is forecast to reach unhealthy levels. Gas fireplaces are exempt.

Can a wood-burning fireplace be installed when the chimney is rebuilt?

Only certain kinds. Under South Coast AQMD Rule 445, a new or used permanently installed device may only be an EPA-certified wood-burning heater, a pellet heater, a masonry heater or a dedicated gas fireplace, and homes whose construction began on or after March 9, 2009 may not have a permanently installed wood-burning device at all.

Is it safe to use the fireplace after a chimney fire?

No, not until the chimney has been swept and evaluated. The Chimney Safety Institute of America warns that a chimney fire can crack flue tiles, break mortar joints and warp metal parts, damage that often cannot be seen from the top or the bottom of the chimney.

What does chimney repair cost in Los Angeles?

It depends on the height of the chimney and the roof access, how much of the masonry is damaged, the liner and fireplace work, and the roof and interior repairs around it. The assessment is free.
