Why Flint Chimney Co Pasadena Is Altadena’s Preferred Chimney Repair Company
Altadena homeowners call us because they’ve been burned before. A company shows up late, looks at the chimney, and the $199 sweep becomes a $4,000 liner pitch with no photo, no explanation, no written scope. We don’t operate that way. Since 2002, as part of the Garrison Partners family, Flint has worked under The Garrison Standard: written price first, written guarantee included, and a live person on the phone 24/7. No voicemail tree. The person who answers at 3:00 a.m. is a person.
We know Altadena specifically. Our techs drive Mariposa, El Molino, Lake Avenue, and the streets climbing into the San Gabriels every week. When a homeowner on E. Altadena Dr. calls about a ceiling stain below the chimney chase, our crew already knows what they’re likely to find: wind-driven rain, a pulled flashing, a spalled crown. That local familiarity is the difference between guessing and diagnosing.
Every repair carries a 365-Day Done Right Promise. If a covered repair fails within one full year, we return at no charge. No argument, no re-quote, no “that’s a different issue now.” We put it in writing on every job. Hank Delano’s name is on the estimate. That’s how we’ve built our reputation across Altadena.
Styles & brands we work with





Chimney Repair Companies in Altadena
Chimney Repair Companies in Altadena work on a specific set of problems: cracked crowns, pulled or rusted flashing, spalled brick, failed mortar joints, and clay flue tiles cracked by decades of seismic settling. A homeowner here needs repair when water gets in, smoke backs up, or a visual inspection shows brick that’s turning to powder. This is not the same as a sweep. A sweep removes creosote; a repair restores the structure so the chimney can do its job safely.
Every Flint repair begins with a documented inspection. We photograph what we find. If we recommend a liner, you see the crack before you approve the work. If we say the chimney can wait a season, we say that plainly. Altadena homeowners deserve nothing less.
Exterior Masonry and Crown Work
A cracked crown lets water into the chimney’s core, and in Altadena’s dry summers, water damage hides until the first rain. We repair crowns with breathable sealant rated for high-wind exposure on foothill streets. Mortar repointing is common on 1920s – 1950s homes where original lime mortar has turned to sand.
Flashing and Water Intrusion Repair
Flashing is the metal seam where the chimney meets the roof. On Altadena’s steep, foothill-angled roofs, flashing takes a beating every time a Santa Ana wind event pushes rain sideways. We replace pulled or corroded flashing with copper, and we check the surrounding roof line so water doesn’t find another path in.
Chimney Masonry Repair in Altadena
Chimney Masonry Repair in Altadena means restoring the brick, mortar, and stone structure itself. This includes tuckpointing (cutting out failed mortar joints and packing new mortar in), spalling brick repair (replacing bricks that are flaking or face-broken), and partial or full rebuilding when the chimney has shifted beyond safe repair. Sears kit houses, Craftsman bungalows, and Spanish Colonial Revivals all have different brick profiles, and we match the existing masonry instead of slapping in whatever’s on the truck.
Altadena’s position against the San Gabriel Mountains means chimneys here carry more wind and seismic load than most of the San Gabriel Valley. Homes on streets like Mariposa and El Molino, where elevation climbs fast, see canyon-funneled gusts that loosen caps and stress mortar beds. That’s a local condition we plan for on every masonry repair, not a generic one-size-fits-all job.
Brick Restoration and Repointing
Older brick chimneys in Altadena were often built with lime-based mortar, which is softer than the brick. Repointing with the correct mortar ratio keeps water from driving into the joints and freezing in the rare cold snap. We hand-match mortar color so the repair blends.
Partial Rebuilds from the Roofline
When the top three to five feet of the chimney is spalled or leaning, we cut out the bad section and rebuild it. This is common on Altadena homes that have weathered decades of wind-driven debris. A partial rebuild typically runs $1,800 – $2,800, depending on brick access and roofline complexity.
Trusted Brands We Service in Altadena
We specify brands we can stand behind on Altadena’s most exposed chimneys. For relining, we work with DuraFlex stainless steel liners and HeatShield cerfractory resurfacing, both chosen because they hold up to the hot fires and rapid thermal cycling common in foothill homes. For crown repair and waterproofing, we use Gelco and Olympia Chimney products that are formulated for exterior masonry exposure. We stock common parts for these brands locally, which means an Altadena repair call doesn’t wait on a slow freight shipment. If the part is in our van, you get it that day. If it’s in the Pasadena warehouse, you get it the next day. Either way, you’ll know the timeline before we start.

AfterCommon Chimney Repair Problems We See in Altadena Homes
- Displaced or missing caps after Santa Ana wind events. Canyon-funneled gusts can exceed 60 mph on streets like Mariposa and El Molino, ripping caps off and leaving flues wide open to debris and rain. We check cap security on nearly every repair call in the foothills, not just on sweeps.
- Cracked clay flue tiles from seismic shifts. Altadena sits against the San Gabriel fault zone, and older chimneys built before modern seismic codes often have hairline cracks in the clay tiles. Those cracks let heat and gases reach the chimney chase, which is a fire risk you cannot see from the ground.
- Rusted dampers from water intrusion. When a crown fails or flashing pulls away, water tracks down into the smoke chamber and sits on the damper. The result is a rusted damper that seizes shut, or worse, rust streaks in the firebox and a creosote smell that won’t go away.
- Spalled crowns and pulled flashing after winter storms. Altadena’s wet seasons are short but intense. Wind-driven rain finds every void. A homeowner might not notice the crack in the crown until a ceiling stain appears below the chimney chase months later. We trace the water path and fix the source, not the stain.
Pricing for Chimney Repair in Altadena, CA

FAQs About Chimney Repair in Altadena
Yes, Altadena chimneys take more wind-driven damage than chimneys in the flat San Gabriel Valley. Canyon-funneled Santa Ana winds can exceed 60 mph on foothill streets, and the debris those winds carry hits caps, crowns, and brick faces hard enough to loosen or crack them. We see more displaced caps and chipped crowns in Altadena than in Pasadena or Arcadia, and the exposure only increases as you climb toward the San Gabriels. Have us check your cap and crown before the first fall fire. Call (626) 657-5513 to book an inspection.
You can wait, but not without cost. A cracked crown lets water into the chimney core every time it rains, and Altadena’s wet season, however brief, does real damage when it arrives. The water that gets in now weakens the masonry slowly, and by fall the repair scope is often bigger: spalled brick, a rusted damper, or a lining that now needs work. If you see hairline cracks in the crown, call (626) 657-5513 and we’ll give you a straight answer on whether it can safely wait, documented in writing.
Rusted dampers are almost always the result of water getting into the smoke chamber from above. In Altadena, the most common sources are cracked crowns, pulled flashing, and caps that have blown off in high wind. When water sits on a cast-iron damper through the winter, the rust seizes the hinge and the damper stops operating. We replace the damper and fix the water source, not just the symptom. If your damper is rusted shut, call (626) 657-5513 and we’ll find where the water got in.
Yes. Altadena sits against the San Gabriel fault zone, and Clay flue tiles in chimneys built before modern seismic codes, most of the housing stock here, crack when the ground shifts. These cracks can be hairline and invisible from the roofline until a chimney inspection camera goes in. A cracked flue tile allows heat and gases to escape into the walls or attic, which is a fire hazard. Our inspections include a camera pass so we can see the flue condition clearly. Call (626) 657-5513 to schedule one.
Wind-driven rain enters through the path of least resistance: a pulled flashing, a cracked crown, or an open flue where a cap used to be. In Altadena, Santa Ana winds push rain sideways against the chimney, and water tracks down the exterior masonry until it finds a gap. From there it follows the chase into the attic and presents as a stain on the ceiling below the chimney. By the time you see the stain, the water has been moving for a while. We trace the path, repair the flashing or crown, and document everything we found. Call (626) 657-5513 and we’ll bring a camera.
On a 1930s Spanish Revival on E. Altadena Dr. near Lake Ave., a homeowner called us for a ceiling stain below the chimney chase. Our tech found the flashing had pulled away after a winter storm, letting wind-driven rain track down the masonry; the chimney crown was also spalled with hairline cracks. We cut out the old flashing, installed new copper flashing, and coated the crown with a breathable sealant before the first fire of the season.
