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 Twin Peaks, CA
Chimney repair in Twin Peaks usually means rebuilding a crown or replacing rusted flashing on a tall, fog-exposed masonry flue, and the work typically runs between $190 and $3,400 depending on how far moisture has gotten into the system. Homes here cluster on steep terraced lots along streets like Twin Peaks Boulevard and Clayton Street, where original 1920s and 1930s brick fireplaces catch the full force of the marine layer. Chimney Sweep Alamo Square has served Twin Peaks since 2011, and we approach every job here with the same rule: we explain what we find, in plain terms, before we touch anything. Call (833) 620-7061 to schedule an inspection.
Why Twin Peaks Homes Are Different
Twin Peaks sits high enough in San Francisco’s fog belt that chimneys here take a beating the flatland neighborhoods never see. Persistent summer fog and damp marine air push moisture deep into brick and stucco, which is why we routinely find efflorescence blooming across chimney faces and spalled crown edges on homes along Portola Drive and Woodside Avenue. The wind is the second problem. Hilltop gusts rattle caps, loosen spark screens, and stress flashing seals, so a chimney that looks fine from the street is often failing where the flue meets the roofline.
The housing stock compounds it. Twin Peaks homes are largely early-to-mid-1900s stucco-over-wood construction, with Mediterranean and Spanish-revival fireplaces as original features. Many flues are tall, offset, or exterior-mounted to clear steep view-side rooflines. That means access frequently requires working from pitched roofs with limited staging room, and the chimney itself is exposed to wind-driven rain on three sides. We account for all of that before recommending any repair, because the right fix on a flatland bungalow is often the wrong fix up here.

Our Main Twin Peaks Services
The two calls we get most often from Twin Peaks homeowners are for annual chimney sweeping and dryer vent cleaning, both of which carry extra weight in this neighborhood because of how the fog and hillside layout affect venting systems.
Chimney Sweep in Twin Peaks
A chimney sweep in Twin Peaks is rarely just a creosote removal job. The fog-driven moisture that sits in masonry flues accelerates the buildup of acidic residue, and frequent cool-weather wood burning keeps creosote layers forming faster than in drier parts of the Bay Area. Our sweep includes a full flue inspection, damper check, and cap assessment, because hilltop wind exposes every weak point. Chimney Sweep in Twin Peaks is a full-page breakdown of what the process looks like on a typical hillside home.
Dryer Vent Cleaning in Twin Peaks
Dryer vents in Twin Peaks homes are frequently longer than code likes, routed through basements or crawl spaces on the downhill side of the lot, then terminated at awkward exterior points. The result is lint accumulation that flatland homes rarely reach, especially when the marine layer keeps the duct interior damp and sticky. We pull the dryer, clean the entire run, and camera-verify the vent path. Dryer Vent Cleaning in Twin Peaks covers the full service and what to expect on steep lots.
Chimney Repair in Twin Peaks
Chimney repair in Twin Peaks usually starts with a moisture problem. The early-1900s masonry fireplaces in this neighborhood absorb fog and rain through cracked crowns and failed flashing, and what begins as a cosmetic stain on the stucco becomes a structural issue inside the flue. Homes on the view side of the hill, along streets like Crestline Drive and Crown Court, show spalled brick and rusted dampers years before comparable homes in Noe Valley or the Castro. Our Chimney Repair service line covers the full arc from cap replacement to full liner work, and every recommendation comes with photographic evidence from the inspection.
Chimney Cap Installation
Signs you need it
Rain streaking down the flue interior, birds or debris inside the firebox, or a rusted, tilted cap sitting loose at the crown line.
What it costs in Twin Peaks
Chimney cap installation in Twin Peaks typically runs $190 – $575 depending on flue size and whether we need to build up the crown surface first.
How we do it
We measure the flue opening, set a stainless or Gelco cap on a clean, stable crown, and mechanically fasten it so hilltop wind can’t rattle it loose.
Chimney Flashing Repair
Signs you need it
Water staining on the ceiling near the chimney, damp drywall around the chase, or rusted, lifted flashing visible at the roofline.
What it costs in Twin Peaks
Flashing repair ranges from $190 for a small step-flashing patch to $1,190 when we need to cut back stucco and rebuild the full saddle on a steep roof plane.
How we do it
We remove the old flashing, inspect the surrounding roof deck, install new step and counter flashing with proper overlap, and seal every joint with high-grade exterior sealant rated for marine exposure.
Chimney Crown Repair
Signs you need it
Crumbling mortar at the top of the chimney, efflorescence streaking down the brick face, or a visible dip in the crown that holds standing water after fog or rain.
What it costs in Twin Peaks
Crown repair in Twin Peaks runs $245 – $1,490, with the upper end covering a full tear-off and recast with a proper overhang and drip edge.
How we do it
We chip away the damaged mortar, build a form where the original overhang is gone, and recast the crown with a Portland-based mix that sheds water instead of absorbing it.

How long does chimney repair take in Twin Peaks?
Most crown and flashing repairs take one day on site. Larger liner or structural work may run two days, and we always tell you the schedule before any work begins.
Will my Twin Peaks chimney need a full liner replacement?
Only if the camera shows cracked clay tiles or gaps in the mortar joints. We show you the footage before recommending HeatShield resurfacing or a DuraFlex liner, and we’ll tell you plainly if a repair can wait.
Brands We Service in Twin Peaks
We install and service what professional chimney engineers actually specify: DuraFlex liner systems, HeatShield resurfacing, Gelco caps, and Copperfield flashing and components. Professional-grade materials, not hardware-store substitutes, and we keep the common parts in local stock so a Twin Peaks repair doesn’t stretch into a multi-week wait.

The two things that push pricing higher in Twin Peaks are roof pitch and flue height. Steep view-side lots mean more staging time and careful rope work, and tall exterior chimneys require longer ladders and more material for crown and flashing work.

- Brianna Coleman"Cap keeps the birds out now, which after two springs of scratching noises is worth every penny."
