Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in San Diego, CA
Chimney repair in San Diego usually comes down to water, not fire. We’re talking about 1910s Craftsman bungalows in North Park and Spanish Revival homes in Mission Hills, where the original brick and stucco chimneys have been soaking in marine-layer moisture for a century. Acorn Chimney Sweep has served San Diego since 2015, and most of our repair calls start the same way: a homeowner notices a stain on the ceiling, a musty smell near the hearth, or a cap that’s rusted through. The decorative fireplaces in these old homes rarely see a fire, so the damage tends to be slow and quiet until it isn’t. Call (844) 510-0293 when you see the first sign.
Why San Diego Homes Are Different
San Diego’s chimney work is dominated by coastal Craftsman and Spanish Colonial bungalows from the 1910s through 1930s in neighborhoods like North Park, South Park, Mission Hills, and Ocean Beach. These original brick fireplaces were built for ambiance, not heating, and today most sit unused. So the real job is usually clearing years of bird nests, soot, and ocean-damp creosote from decorative fireplaces rather than servicing active wood-burning heating systems. Along the 92106 and 92109 coastal strip, the marine layer keeps mortar joints damp year-round, and that’s what drives spalling brick and corroded caps. The mild climate means fireplaces get lit maybe a dozen nights a year, so flues sit idle and accumulate debris instead of fresh creosote. In Ocean Beach and Point Loma, we routinely pull whole rookeries of pigeon and seagull nests, plus the occasional raccoon, out of uncapped flues. Nobody lights a fire often enough to notice until the draft stops working or water shows up on the mantel.
Styles & brands we work with
Our Main San Diego Services
Two services account for most of what San Diego homeowners call us about: chimney sweeping for the wood-burning fireplaces and stoves that still get seasonal use, and dryer vent cleaning for the hazard most people never see. Here’s how each one works in San Diego specifically.
Chimney Sweep in San Diego
San Diego’s coastal homes don’t build up the heavy creosote you’d see in a colder inland city, but the soot and debris that do collect stay tacky from the damp air, which means mold and musty odors in unused flues. In North Park and South Park, those 1910s bungalows often have narrow, kinked flues that haven’t been opened in decades. We clear nests, brush the walls, and check every component while we’re there. If the fireplace has been sitting idle for years, this is the service to start with. Chimney Sweep in San Diego covers the full process, including what we look for in older brick fireplaces near the coast.
Dryer Vent Cleaning in San Diego
Your dryer vent is a fire hazard hiding behind the wall, and in San Diego’s older homes the vent runs are often longer and more convoluted than they should be. Lint packs into the pipe, the dryer runs hotter, and the heating element works harder than it was designed to. We clean the full run from the dryer to the exterior cap, check the cap for proper airflow, and show you what came out. It’s a service most chimney-only companies never touch. Dryer Vent Cleaning in San Diego explains what we do and why it matters in this climate.

Chimney Repair in San Diego
Chimney repair in San Diego is mostly about keeping water out of structures that were never built for constant dampness. The soft, lime-rich mortar in those 1910s and 1920s chimneys degrades faster than modern mixes, and once the cap or crown fails, water seeps into the flue and starts breaking down the brick from inside. The marine layer does the rest. Chimney Repair is one of our core services because most San Diego chimneys need some level of repair before they’re safe to use again, even if they only get lit once a year.
Chimney Cap Installation
Signs you need it
You hear birds or animals in the chimney, you see water staining below the flue, or the old cap has rusted through and no longer covers the opening.
What it costs in San Diego
Chimney cap installation in San Diego typically runs $125 to $650, depending on the flue size and whether we’re installing a standard single-flue cap or a custom multi-flue cover.
How we do it
We measure the flue, install a properly sized cap from Copperfield or Gelco secured to the crown with stainless fasteners, and check that the mesh keeps birds out without restricting draft.
Chimney Cap Replacement
Signs you need it
The existing cap has rusted through, the mesh is torn and birds are getting in, or the cap has lifted loose from the crown and rattles in the wind.
What it costs in San Diego
Cap replacement in San Diego costs $125 to $650, including removing the old unit and hauling it away.
How we do it
We remove the failed cap, inspect the flue and crown beneath it, and install a new Copperfield or Gelco cap sized to the flue with proper mechanical fastening.
Chimney Liner Installation
Signs you need it
You have cracked or missing flue tiles, visible gaps in the liner, or the chimney can no longer safely vent a fireplace, stove, or insert.
What it costs in San Diego
Liner installation in San Diego typically runs $2,500 to $7,000, with HeatShield resurfacing on the lower end and full DuraFlex stainless relining on the higher end.
How we do it
We run a camera through the flue, measure the exact dimensions, then install either a HeatShield resurfacing system or a DuraFlex flexible stainless liner, depending on the condition of the existing flue.
Chimney Flashing Repair
Signs you need it
You have water staining on the ceiling near the chimney, damp drywall around the firebox, or visible rust and gaps in the flashing where the chimney meets the roof.
What it costs in San Diego
Flashing repair in San Diego typically runs $195 to $550, depending on how much of the existing flashing needs to be cut out and replaced.
How we do it
We remove the failed flashing, inspect the underlying felt and roof deck, and install new step and counter flashing sealed against the chimney with proper overlap.
Chimney Crown Repair
Signs you need it
The concrete crown has visible cracks, the surface is spalling or crumbling, or water pools on top of the chimney instead of draining off.
What it costs in San Diego
Crown repair in San Diego typically runs $350 to $1,200, depending on whether we’re filling cracks and sealing or re-building the crown entirely.
How we do it
We clean the crown surface, fill cracks with a flexible sealant, then re-crown with a properly sloped mortar mix that sheds water away from the flue, and we follow with a waterproofing treatment.

Can a decorative fireplace in an old San Diego home still be safe to use?
Only after a proper inspection. Many of those 1910s and 1920s fireplaces in North Park and Mission Hills have deteriorated mortars and open flues that were never designed for regular use. Call (844) 510-0293 and we’ll camera-check it before you light anything.

What San Diego Customers Say
"Swept it, capped it, and installed a proper damper. The downdraft smell in the summer that we'd lived with for years is gone."
— Grace Wong"Liner was cracked in two places. He walked me through the repair options honestly, including the one that was cheaper for him and better for me."
— Lucia Ramirez"Crown was cracked and taking water. Repaired it rather than quoting a rebuild, which the previous company had pushed hard for."
— Diego Reyes
