Chimney Cap Installation
Chimney Cap Installation protects the single most exposed opening in your home – and in Bernal Heights, where fog, rain, and crows are all part of the equation, a missing or undersized cap is an open invitation for water, nesting, and downdrafts. We also offer Chimney Repair in Bernal Heights for homeowners dealing with more extensive chimney issues. We install caps sized to your flue and matched to your ventilation needs, using Famco and Copperfield terminations rather than whatever is on the shelf at the supply house. If you cook with gas or run a wood fireplace often, we’ll spec a cap that handles the exhaust volume without choking draw. A proper cap also keeps rain from saturating the flue liner and accelerating deterioration in already-old chimneys.
What We Install
Stainless steel and copper caps from Famco and Copperfield, sized to your flue tile or liner. We also install spark-arrestor mesh where the fire code requires it, which is common in the dry hillside pockets around Bernal Heights.
Why Bernal Heights Homes Need This
Homes on the north slope catch more wind-driven rain than the flatlands. A cap that sheds water cleanly means less moisture reaching your damper, firebox, and smoke shelf – the start of almost every expensive Chimney Repair in Bernal Heights.
Chimney Cap Replacement
Chimney Cap Replacement is what happens when your existing cap has rusted through, blown off in a winter storm, or simply never existed in the first place. We see caps on Bernal Heights rooftops that are so corroded they crumble in our hands during inspection. The fix is straightforward: measure the flue, remove the old termination, and install a new cap that suits the venting type. For wood-burning fireplaces, that often means a stainless cap with spark arrestor; for gas logs, a cap that protects against downdraft without trapping exhaust. We do both, and we do it without charging you for a liner repair you don’t need.
When Replacement Beats Repair
If the cap is rusted through, bent beyond seating, or the mesh is torn open wide enough for a bird, replacement is the honest call. Trying to patch a cap that’s already failing just moves the leak problem six months down the road.
Matching Cap to Flue
The wrong cap – too small, too restrictive, wrong material – creates draft problems you’ll feel in your living room. We match the replacement cap to the flue diameter and your heating appliance so the chimney pulls like it should.
Chimney Liner Installation
Chimney Liner Installation is the repair that matters most when your clay tile liner has cracked, spalled, or separated – a condition we document with camera inspection before recommending anything. In Bernal Heights, homes built before the 1970s commonly have original terra cotta liners that are now failing at the mortar joints, which is a real fire and carbon monoxide risk if you use the fireplace. We install DuraFlex stainless liners sized to the existing flue, including flexible configurations for the offset, dog-legged chimneys that are common in this neighborhood’s older construction. It’s not a cheap fix, but it’s the one that makes a chimney safe to burn again.
When a Liner Is Required
After a chimney fire, after a camera inspection confirms gaps between tile sections, or when you’re installing a new heating appliance that demands a properly sized flue. These aren’t suggestions – they’re code requirements we help you meet correctly.
HeatShield as the Alternative
When the original liner is still structurally sound but has lost its surface integrity, we can resurface it with HeatShield ceramic instead of a full liner replacement. It’s a faster, less invasive repair that often saves thousands compared to tearing out and rebuilding the flue.
Chimney Flashing Repair
Chimney Flashing Repair addresses the most common source of water intrusion in a chimney system – the metal transition where the chimney rises through the roof. Bernal Heights sees enough rain and wind that flashing that was installed incorrectly, or that’s simply been through twenty wet seasons, starts separating from the masonry or the roofing material. We repair and replace flashing with proper step and counter-flashing technique, sealed correctly so water sheds away from the chase. You’ll know you need this when you see water staining on the ceiling near the fireplace or dampness on the chimney brick above the roofline.
Why Flashing Fails
Roof movement, rust on galvanized flashing, bad original installation, or a roof replacement that disturbed the existing flashing. Any one of those lets water run down the chimney chase into walls and ceilings.
What We Do Differently
We cut a proper reglet into the mortar joint for counter-flashing, rather than surface-sealing against the brick. Surface sealing always fails; mechanical flashing in the joint lasts decades.
Chimney Crown Repair
Chimney Crown Repair fixes the concrete slab that caps the top of the chimney above the flue – and a cracked crown is one of the most frequently missed defects we find during chimney sweeps in Bernal Heights. The crown is your chimney’s roof, and when it cracks or was never built with a proper overhang, rain soaks directly into the masonry below, causing spalling, efflorescence, and eventually structural damage. We repair crowns with proper expansion joints and a correct drip edge, using materials that will survive the wet season rather than a thin layer of patch that washes away in two years.
The Bernal Heights Climate Factor
Fog intrusion is a chemical erosion pattern we see on the hillside: moisture sits on a cracked crown, wicks into the mortar, and the freeze-thaw cycle in the winter expands every fissure. The fix is structural, not cosmetic.
Signs Your Crown Is Failing
Hairline cracks, missing chunks, weeds growing from the top of the chimney, or a crown that sits flush with the brick instead of overhanging by an inch and a half. Any of these means it’s time.
Chimney Repair Companies
Chimney Repair Companies in San Francisco range from handyman services that moonlight in flue work to full-service ventilation firms that carry materials like DuraFlex and HeatShield. The difference matters when you’re paying someone to protect your home from fire and carbon monoxide. We position ourselves on the full-service end: a chimney sweep that also installs liners, repairs flashing, replaces crowns, and – importantly – cleans dryer vents, which are a separate combustion exhaust system most “chimney” companies ignore. Scott Hobbs’s crew handles the inspection, the recommendation, and the repair without handing you a referral card for someone else.
What to Ask Any Company
Ask what brands they install. Ask if they camera-inspect before recommending a liner. Ask if they repair flashing to the joint or just caulk the surface. The answers tell you which kind of company you’re dealing with.
Why We’re Different
We name what we use – DuraFlex liners, HeatShield resurfacing, Famco and Copperfield caps. Most companies don’t. When you can verify the material, you can verify the quality of the repair.
Chimney Masonry Repair
Chimney Masonry Repair covers the brick and mortar work that holds your entire chimney together – from repointing crumbling mortar joints to rebuilding damaged brick courses to restoring the smoke chamber. Bernal Heights is full of pre-war homes with brick chimneys that have absorbed a century of weather, and the damage shows up as spalled brick faces, sand-textured mortar that you can scrape away with a finger, or a chimney that visually leans. We repair masonry with appropriately matched mortar for the age and composition of the brick, not a one-size portland mix that sets too hard and traps moisture inside the wall.
Repointing vs. Rebuilding
When the mortar is failing but the bricks are intact, repointing is the cost-effective fix. When bricks themselves are cracked, spalled, or the structure has shifted, we rebuild the affected section – and we’ll tell you which one you actually need based on the camera evidence.
Mortar Matching Matters
Older San Francisco homes were built with lime-based mortars that flex with temperature and seismic movement. Using a too-hard modern mortar causes the brick itself to fail. We match the mortar to the chimney’s era.

AfterBrands We Service
We work with a specific set of manufacturers because their tolerances and material quality hold up in San Francisco’s wet-dry-wet cycle. DuraFlex liners are what we recommend for most full relining jobs – their stainless alloy stands up to condensation in gas applications and withstands the temperatures of wood burning. We install them in flexible configurations for the offset flues that are common in older Bernal Heights construction, where rigid sections won’t navigate the bends.
HeatShield is our ceramic resurfacing system for liners that are still structurally sound but have lost their smooth surface or developed minor joint gaps. Famco and Copperfield supply the caps, dampers, and termination hardware we install – components sized correctly rather than adapted on site. Whether you have a chimney currently fitted with any of these or a completely original clay tile setup, we can inspect it, diagnose it, and repair it properly.
Signs You Need a Pro Right Now
- Water in the firebox or staining around the fireplace. This is usually flashing or crown failure, and it means water is already inside your chimney system, working on the mortar and liner. The longer it sits, the bigger the repair.
- A smoky smell even when you haven’t burned in days. This points to a draft problem caused by a cracked liner, a blocked flue, or a failed damper. Some of those are fire hazards, not just annoyances.
- Crumbling mortar or spalled brick on the exterior chimney. You’re watching structural deterioration in real time. In Bernal Heights, where rain drives into exposed masonry on the hill, this accelerates every winter.
- Visible cracks in the chimney crown. The crown is the roof of your chimney. A cracked crown channels water directly into the brick and mortar below it, which turns into a masonry repair that could have been avoided.
- Rust on the damper or firebox. Rust means water is getting past the cap or crown. Water plus heat cycling is what destroys liners from the inside out.
Our Process, Step by Step
- 1
Inspection and camera scope. We start by actually looking. That means a visual inspection of the crown, cap, and flashing from the roof, and a camera run through the flue to document the liner condition. You see the footage too – it’s your chimney.
- 2
Findings and recommendations. We walk you through what the camera shows and what it means in plain terms. If there’s repair work needed, we show you why the evidence supports it. If nothing’s urgent, we tell you exactly how long you can safely wait and what to watch for.
- 3
Flat-price estimate before work starts. No time-and-materials games. We quote the repair for an agreed scope at an agreed price, and we stick to it. What we show you on the camera is what we fix.
- 4
Repair with named materials. Whether it’s a DuraFlex liner, a Famco cap, HeatShield resurfacing, or masonry repointing, the material spec is in the quote. You know what’s being installed in your home.
- 5
Verification and cleanup. We camera-check our liner work, run a smoke test for draft on any ventilation repair, and make sure the roof and firebox area are cleaner than we found them. Then we show you what we did and why it’s right.
How Much Does Chimney Repair Cost in Bernal Heights?
Chimney Repair – Potrero Hill and Bernal Heights costs depend on which component has failed, but here’s what we see in this market: a cap replacement or installation runs about $200 to $600 depending on the flue size and whether you need custom fabrication. A flashing repair is typically $400 to $1,200 depending on how much of the old flashing has to come out and whether the roof is tile, shingle, or bitumen – tile and bitumen take more careful work around the chimney base. Liner work is the big-ticket item: a full DuraFlex liner installation usually lands between $2,500 and $6,000 depending on the flue length, and HeatShield resurfacing typically runs $1,200 to $3,000 when the existing liner qualifies.
Crown repair or rebuild sits in the $800 to $2,500 range depending on whether we’re sealing cracks or forming a new crown from scratch. Masonry repointing is usually $1,500 to $4,000 depending on the chimney’s height and the extent of mortar loss. What drives cost up: roof access difficulty, chimney height, the condition of the existing masonry, and whether your flue is offset and requires flexible liner manipulation. What drives it down: early intervention, a properly functioning cap that kept water out, and annual sweeps that catch minor deterioration before it becomes structural. A free estimate includes the camera inspection and a written, line-by-line scope so you know exactly what you’re paying for and why.

Frequently Asked Questions About Chimney Repair in Bernal Heights
Chimney repair is any corrective work on the structural or ventilation components of your chimney: the cap, crown, flashing, liner, damper, or masonry. It differs from chimney sweeping, which is maintenance cleaning – repair fixes components that have already failed or are actively failing. A proper repair restores the chimney to safe operating condition.
Most cap replacements, crown seals, and flashing repairs are completed in a single visit of a few hours. A liner installation or major masonry rebuild typically takes one to two days depending on roof access and the extent of the damage. We’ll give you a time window when you book.
The range runs from about $200 for a simple cap replacement up to $6,000 for a full liner installation on a tall or offset flue. Most repairs we do in Diamond Heights and Bernal Heights fall in the $400 to $2,500 range. You get a free camera inspection and a written flat-price estimate before any work starts, so the number never surprises you.
Yes. We work on masonry chimneys, prefabricated systems, and the major liner and cap brands including DuraFlex, Famco, Copperfield, and HeatShield. If you have a fireplace that was built with clay tile liners from the 1950s or a modern gas insert, we service it.
We prioritize active water intrusion, visible chimney fires, and carbon monoxide leaks in the Bernal Heights area and will work to get a crew out quickly for a dangerous condition. Call (844) 745-4668, and we’ll tell you what needs to happen now versus what can wait for a scheduled visit.
