Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Repair Across San Gabriel
Chimney repair in San Gabriel typically runs between $350 and $1,800 depending on whether we’re repointing brick, replacing a flashing, or rebuilding a crown. Most repairs on the older masonry homes around the Mission District and the North San Gabriel tracts get completed in one visit, with a written quote agreed on before we start. If you’ve noticed water stains near the firebox, spalling brick on the exterior, or a fireplace that drafts smoke back into the room, call us at (830) 251-4560. We’ll schedule an inspection, run a camera up the flue, and show you exactly what we see.
Flint Chimney Sweep has been in business since 2002 as part of the Garrison Partners family of independently owned chimney service companies. Our crews know San Gabriel’s housing stock, especially the 1920s to 1950s masonry chimneys in neighborhoods like San Gabriel Village and the streets around Las Tunas Drive and San Gabriel Boulevard. Dispatch and scheduling run through our Los Angeles office, but the technicians who arrive at your door know this city’s chimneys.
Why Flint Chimney Sweep Is San Gabriel’s Preferred Chimney Repair Company
We operate under The Garrison Code, a written standard that every Garrison Partners location follows. That means three things on every San Gabriel job: a background-checked, uniformed technician, a written price before any work begins, and a repair covered by our 365-Day Done Right Promise. If a covered repair fails within one full year of the service date, we return at no charge. No argument, no invoice. That’s the whole point of putting the guarantee in writing.
Hank Delano leads our repair team, and the process he runs keeps homeowners from guessing. You get photos of every defect from the camera inspection before you approve anything. You get a flat quote that doesn’t change when the crew arrives. San Gabriel homeowners who’ve dealt with no-show contractors or prices that creep up at the door tend to notice the difference quickly. Hank Delano’s crews arrive inside the window we give you, in uniform, ready to show you the evidence.
Reviews from San Gabriel customers consistently mention two things: the technician showed up when promised, and the price on the invoice matched the number on the quote. We built the whole operation around those two outcomes because they’re the two things chimney companies most often get wrong.
Chimney Repair Companies in San Gabriel
Chimney repair companies in San Gabriel should be able to show you the damage before asking for money. That’s our starting point. A proper repair job here starts with a camera run through the flue, because most of what needs fixing is hidden behind brick and inside the smoke chamber. We scope every liner, damper, crown, and flashing point, then hand you a written quote with the photos to back it up.
Camera Inspection First, Quote Second
We won’t quote a repair on sight alone. A sooted firebox might look fine from the outside while a cracked flue liner section sits just above the damper, letting carbon monoxide into the house. The camera shows us what’s actually there, and we email you the images. You see the defect before you approve the fix.
Written Price, Fixed Scope
Every repair quote in San Gabriel gets delivered in writing before any tool comes off the truck. The number you approve is the number you pay. We specify materials by name, DuraFlex or HeatShield or Famco, depending on what the flue needs. No upsell, no on-site surprises.
Chimney Masonry Repair in San Gabriel
Chimney masonry repair in San Gabriel is usually a water problem before it’s a fire problem. The city sits in a basin that traps cool, damp marine air overnight, especially in the older tracts between San Gabriel Boulevard and the Mission District. Brick and mortar soak up that moisture and hold it longer than the drier foothill towns above the valley. Over years, that means cracked chimney crowns, spalled brick faces, and flashing that pulls away from the roofline.
Crown and Flashing Work
Most of our masonry calls in San Gabriel start with a leaking crown or a failed flashing point. Water gets in, the mortar softens, and bricks start popping. We rebuild crowns with a proper slope, repoint failing mortar joints, and replace flashing with materials sized to the roofline, not whatever’s on the truck. A crown rebuild in San Gabriel typically runs $900 to $1,600 depending on height and access.
Repointing and Tuckpointing
Repointing means cutting out deteriorated mortar and packing in fresh mortar that matches the original joint profile. Tuckpointing goes a step further, adding a thin contrasting line to create the crisp joint appearance older brickwork was built with. On a standard one-story San Gabriel home, repointing a chimney from the roofline up runs roughly $800 to $1,400. The work keeps water out and stops the slow structural rot that turns a repointing job into a rebuild.
Trusted Brands We Service in San Gabriel
We specify materials by the job, not by margin. When a San Gabriel chimney needs a new liner section, we pull the DuraFlex catalog and order exactly what the flue dimensions call for. When a damper has rusted through, we replace it with a Famco or Copperfield unit sized to the throat. We work with HeatShield where a full reline isn’t necessary but a cracked section needs reinforcement. Parts for San Gabriel jobs are ordered locally, which keeps turnaround tight.
Common Chimney Repair Problems We See in San Gabriel Homes
- Water-driven crown cracking. The basin’s cool overnight air keeps San Gabriel masonry damp, so crown cracks widen fast and let water into the brick below. We see this constantly on homes built between the 1920s and 1950s.
- Flashing leaks at the roofline. Older homes around Las Tunas and San Gabriel Boulevard often have original flashing that has pulled away from the chimney or rotted through. The first sign is usually a watermark on the ceiling near the fireplace.
- Rusted dampers and sooted smoke chambers. A firebox that backdrafts in a San Gabriel winter is usually a damper that won’t seat or a smoke chamber caked with soot, not bad wood. We see it on both the original bungalows and the mid-century ranch homes.
- Third-degree creosote glaze. This is the hardened, tar-like residue that accumulates inside flue liners after repeated fires, particularly on chimneys that haven’t been swept in years. A standard brush doesn’t remove it. Chemical treatments or a reline usually does.

FAQs About Chimney Repair in San Gabriel
We run a camera up the flue before recommending anything. A cleaning handles standard soot and early creosote. If the camera shows cracked liner sections, spalled brick, a rusted damper, or water staining, we show you the images and quote the repair. The decision is yours, and the evidence is on the screen in front of you. Call (830) 251-4560 to schedule an inspection.
If you burn fewer than a dozen fires a year, an annual camera inspection may be more than you need, but every two years is a good rhythm in San Gabriel. The reason isn’t creosote buildup, it’s water. Our basin’s overnight damp contributes to crown and flashing deterioration year-round, even on a fireplace that never gets lit. A camera run catches those before the brick starts moving. Call (830) 251-4560 and we’ll tell you honestly whether an inspection is worth your money this year.
First-degree creosote is a dry, sooty dust that brushes out easily. Third-degree creosote is a hardened, shiny glaze fused to the flue liner, and it’s the type most likely to feed a chimney fire. It won’t come out with a standard brush. A sweep who’s been trained to recognize it will tell you a chemical treatment or a section reline is the correct fix. In San Gabriel, older flues with inefficient drafts tend to build third-degree glaze faster, especially on fireplaces with undersized liners for the firebox. Call (830) 251-4560 for a camera inspection that shows us exactly what’s in your flue.
Yes, in some cases you can wait, and we’ll tell you that straight. A small crown crack that’s not actively leaking can wait a season if you’re not burning. A flashing point that has pulled away and is letting water onto the roofline should not wait, because the damage spreads to the structure around it. San Gabriel’s damp overnight air means moisture lingers once it gets in, so what’s a $900 crown job in fall can become a $5,000 rebuild by spring. We’ll show you the photo and give you the straight answer. Call (830) 251-4560 for a camera inspection and we’ll tell you what can wait and what can’t.
The price is fixed before we start, in writing. We quote based on the camera inspection and the scope of work we’ve agreed on. If we find something new during the repair, we stop, show you the evidence, and get your approval on a written change before any additional work happens. What we won’t do is hand you a different number at the door. That’s the Garrison Standard, and it applies to every repair in San Gabriel. Call (830) 251-4560 for a free estimate.
