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 Mission District, CA
Chimney repair in Mission District usually means addressing what a century of wet winters and shared masonry walls have left behind: cracked crowns, failed flashing, and unlined brick flues that were never built for today’s gas inserts. Sunstone Chimney Sweep has served Mission District since 2011, and we handle the whole sweep-and-repair sequence in one visit, so you’re not coordinating between a cleaning crew and a mason. If you suspect a liner problem or you’re seeing water stains near the chimney, call (833) 593-0743 for a straight answer and a free estimate.
Why Mission District Homes Are Different
The Mission District’s chimney stock runs through dense rows of 1900s to 1920s Edwardians and Victorians, mostly two to four stories, with one chimney per unit threading through shared masonry walls. That matters because on many blocks the chimneys step in a continuous stair-step along attached party walls. We’ve worked rooftops where the same unlined 1920s flue repeats house after house, and once one home fails a camera inspection, three neighbors on the block call within the same week.
The Mission sits in a fog shadow, so it gets less coastal damp than the Sunset or Richmond, but the rainy winter months still push water through deteriorated crowns and flashing. That water intrusion is the leading cause of masonry failure here. Add the post-2019 wave of owners relining flues to satisfy Bay Area Air Quality Management District rules before selling or renting, and most of our Mission District repair calls involve a camera inspection that confirms what the water stains already suggested.

Our Main Mission District Services
Most Mission District homeowners call us for one of two things: an annual sweep to keep a working fireplace or insert burning safely, or dryer vent cleaning to reduce a fire risk that doesn’t get the attention it should. Here’s what each involves locally.
Chimney Sweep in Mission District
A Mission District sweep on a 1920s flue needs more than a brush run. We’re checking for the specific failure pattern these older homes share: unlined or parged brick surfaces that shed mortar over time, reduced draft caused by neighboring units sharing the wall, and creosote buildup that behaves differently once a gas insert has replaced the original wood fire. Detailed service and pricing information is on our Chimney Sweep in Mission District page.
Dryer Vent Cleaning in Mission District
In Mission District Victorians and Edwardians, dryer vents often run long, horizontal, or through interior walls, all of which increases lint accumulation. The U.S. Fire Administration identifies dryer vent fires as one of the leading appliance-related causes of residential fires, and we treat this as a safety-critical service, not an add-on. See the full scope of duct work on our Dryer Vent Cleaning in Mission District page.
Chimney Repair in Mission District
Chimney repair in Mission District typically means fixing what years of fog-shadow weather and shared-wall construction have done to a 100-year-old system. The dense 1900 – 1925 Edwardians and Victorians here often have original unlined brick flues, some parged, some tapped later for gas furnaces or inserts, and a number that were never legal for that reuse in the first place. Rainy winters drive water through crowns and flashing, and once a flue fails inspection, the repair usually involves more than pointing a few bricks. Sunstone Chimney Sweep handles the full Chimney Repair scope, from liner installation to crown rebuilding, with the right professional-grade material specified for the system, not the cheapest option on the shelf.
Chimney Liner Installation
Signs you need it
You’ll see flaking tile or mortar at the cleanout, a gas insert that doesn’t draft consistently, or a camera inspection showing gaps in the original flue surface.
What it costs in Mission District
Chimney liner installation in Mission District typically falls between $1,800 and $4,200, depending on flue height and whether a gas or wood-burning system is being lined.
How we do it
We run a camera inspection first, then size and install a stainless steel liner (DuraFlex when it fits the system) through the full flue run, connect it at the appliance collar and the top plate, and finish with a cap.
Chimney Crown Repair
Signs you need it
Hairline cracks that widen after rain, crumbling concrete at the top of the chimney, or water stains on the ceiling near the flue usually point to a failing crown.
What it costs in Mission District
Chimney crown repair in Mission District typically runs $550 to $1,400; the price varies with how much of the existing crown is salvageable and how large the flue opening is.
How we do it
We remove loose or cracked crown material, prep the surface, and pour a new flue gas-tight crown with the right pre-slope and drip edge so water moves away from the flue, not into it.
What Chimney Repair Costs in Mission District
| Item | Typical range in Mission District |
|---|---|
| Chimney liner installation | $1,800 – $4,200 |
| Chimney crown repair | $550 – $1,400 |
| Chimney cap installation | $300 – $700 |
Do I need a new liner, or can a sweep just clean it?
A cleaning removes creosote, but it doesn’t repair gaps or cracks. In Mission District homes from 1900 – 1925, if the camera inspection shows missing mortar joints or flaking tile, the liner is no longer containing combustion gases, and cleaning it won’t fix that.
Can chimney repair be done the same day as a sweep?
In many cases yes. Crown work and cap installation can often be completed the same day as the sweep, especially when we’ve already seen the camera footage and know the flue condition before arriving.
Brands We Service in Mission District
We stock and install from professional trade lines including DuraFlex, Olympia Chimney, and Famco, sourced from the same suppliers chimney restoration specialists use nationwide. Most common liner and cap components are on the truck, which keeps Mission District repair visits to a single trip. Learn more on our brands page.

FAQs About Chimney Company in Mission District
Most Mission District appointments are scheduled within five to seven business days. When a neighbor’s flue has failed an inspection and several homes on the same block book together, we’ll often schedule them back-to-back on the same day since we’re already working the same roofline.
Most chimney liner installations and crown repairs in San Francisco fall under standard residential repair and don’t require a separate permit, but if the work involves structural masonry changes or party-wall modifications, the city may require review. We can tell you which category your job falls into during the estimate.
Yes, and it’s the most common Mission District repair, where chimneys step along the party wall.

What Mission District Customers Say
"Level two inspection before we bought the house. The report was detailed enough to use as a negotiating point and he explained every photo in it."
- Stephanie Reed"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."
- Xavier Dawson"Crown was cracked and taking water. Repaired it rather than quoting a rebuild, which the previous company had pushed hard for."
- Norma Castillo
