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.

Chimney Liner Installation in San Rafael
Chimney liner installation in San Rafael is a repair we recommend when a camera inspection shows cracks, gaps, or missing sections in the existing flue liner, or when an older home has an insert or appliance venting into an unlined flue. The liner channels smoke and combustion gases safely out of the house. A cracked liner lets heat and carbon monoxide reach the surrounding masonry, which is how chimney fires start in older structures. San Rafael homes built in the 1920s through 1950s frequently have original clay tile liners that crack from decades of heating and cooling cycles, and homeowners in Dominican and Gerstle Park often don’t know until the Level 2 camera inspection shows it.
For most liner replacements in San Rafael, we install DuraFlex stainless steel liners. The liner is specified by the job, not by margin. A typical liner installation runs $1,200 – $2,800 depending on flue length, access, and whether the old liner needs to be removed first. If the existing firebox and damper test fine, we leave them alone and only replace what’s failed. That’s a straight answer, not an upsell.
When the old firebox stays
A cracked liner doesn’t automatically mean a new firebox. We inspect the firebox and damper separately. If they’re sound, the new liner gets connected to the existing setup. One recent job off Grand Avenue: a 1920s bungalow with spalling on the crown and a rust streak down the firebox wall. The liner above the smoke chamber had cracked, but the firebox and damper tested fine. We installed a DuraFlex liner, a new copper cap, and step flashing tied into the roof. The photo report showed the difference, and the homeowner kept the original firebox.
Chimney Flashing Repair in San Rafael
Chimney flashing repair in San Rafael is the fix for water getting in where the chimney meets the roofline. Flashing is the sheet metal that seals the joint between the chimney and the roof. When it lifts, corrodes, or pulls away, rainwater runs down the chimney chase, soaks the masonry, and eventually shows up as a stain on the ceiling or a rust streak in the firebox. San Rafael’s winter rains are the stress test. A flashing repair typically runs $325 – $850 depending on how much flashing needs to be replaced and whether the roof needs to be cut back around the chimney.
Stucco-clad chimneys hide the problem
In Dominican and Gerstle Park, many chimneys were stuccoed over decades ago. The stucco traps moisture against the original brick, so flashing and crown failures happen silently. By the time you see spalling on the interior firebox wall, water has been working through the masonry for a while. That’s why our Level 2 camera inspection in San Rafael always includes the flashing and crown, even when the homeowner called about something else.
Trusted Brands We Service in San Rafael
We work with professional-grade chimney materials and we name them so you can verify quality independently. For liner work, we specify DuraFlex stainless steel. For crown and masonry repairs, we use HeatShield and Gelco sealants and resurfacing products. For caps and dampers, Olympia Chimney and Famco. When a San Rafael job needs a part, we order it by the specification that fits the repair, not whatever has the best margin. Most common parts are stocked for San Rafael-area jobs, which keeps turnaround short on repairs like damper replacements and cap installs. Our Chimney Repair team specs the material, writes the price, and only then starts the work.
Common Chimney Repair Problems We See in San Rafael Homes
- Stucco-clad chimneys trapping moisture. Older Dominican and Gerstle Park homes often have brick chimneys covered in cosmetic stucco. The stucco holds water against the brick, so flashing and crown failures stay hidden until spalling shows up inside the firebox.
- Retrofit inserts without a proper liner. Homes with wood stoves or inserts installed years ago often vent into an unlined or partial flue. Creosote accumulates in the smoke chamber where a brush can’t reach, and first-degree creosote can harden into third-degree tar glaze, which is a chimney fire risk.
- Cracked original dampers and fireboxes. Bungalows near downtown San Rafael from the 1920s often have original dampers that have warped or cracked from decades of use. A rust streak in the firebox gets mistaken for a cleaning issue when it’s actually a repair.
- Spalling on crowns from winter rain exposure. The crown is the concrete cap at the top of the chimney. Once water gets into small cracks and freezes, the surface starts flaking off. In San Rafael’s wet season, open crown cracks accelerate brick damage below.

FAQs About Chimney Repair in San Rafael
A camera inspection answers this in about an hour. If the flue liner shows cracks, gaps, or missing sections, it’s a repair. If the creosote build-up is first-degree and the liner is intact, a sweep is likely enough. We run a Level 2 inspection on repair calls in San Rafael, and you get a photo report showing exactly what the camera saw. If we can’t show you a problem, we don’t recommend the work. Call (830) 251-4560 to book an inspection.
Third-degree creosote is tar glaze, the hardened, shiny form of creosote that no brush can remove. It forms when first-degree creosote is repeatedly heated and cooled without being cleaned, which happens in San Rafael homes with retrofit inserts venting into unlined or partial flues. It’s a chimney fire risk and requires chemical or mechanical removal. If an inspection shows third-degree creosote in your flue, we’ll tell you plainly and give you a written price for the fix.
Yes. Stucco-clad chimneys in San Rafael hide underlying masonry damage, so we typically remove a section of stucco to inspect the brick, flashing, and crown underneath. That’s the only way to know if water is getting in. We don’t repair over the stucco without seeing what’s behind it. The inspection tells us whether the repair is a flashing fix or something deeper in the brick.
Once a year if you burn regularly, and before the wet season if you don’t. San Rafael’s winter rains are hard on flashing and crowns, and small leaks become big masonry repairs when water has six months to work through the brick. If you burn wood at all, a yearly Level 1 inspection with a sweep is the standard. Call (830) 251-4560 and we’ll book it.
Yes, and it’s a common combination. The firebox and the liner get inspected separately. If the firebox tests fine, we leave it alone and install the DuraFlex stainless liner to the existing damper and firebox. We won’t replace a working firebox just to make the job bigger. You get a written price for the liner work only, and the photo report shows what was done.
