Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterHow Much Does Chimney Liner & Rebuild Cost in Alamo Square?
In Alamo Square, a chimney liner installation typically runs $2,400 to $5,800, while a partial chimney rebuild (crown, top courses, and flue tile) usually lands between $1,800 and $6,500. A full-height rebuild on a single-story Victorian-era flue can reach $9,000 to $14,000. Most of the homes we see in this neighborhood fall into the middle of those ranges, but the only way to know your number is to have the flue opened up and inspected.
If you already suspect the liner is failing – smoke backing into the room, a flue that smells like creosote after rain, or visible cracks in the tile – call us at (833) 620-7061 and we’ll schedule a look. A free estimate takes about an hour and we’ll explain what we find before we touch anything.
Chimney Liner & Rebuild Cost Breakdown (2026)
Here’s what the work actually breaks down to in the Alamo Square market. These ranges reflect the older masonry stock around Alamo Square Park, the narrow lots along Fell and Hayes, and the fact that most of these chimneys were built between 1890 and 1915 – they don’t age the way a 1970s flue does.
| Line item | Typical 2026 range |
|---|---|
| Full-length flexible liner install (DuraFlex, single-flue, ~25 ft) | $2,400 – $4,200 |
| Insulated liner system for gas or wood appliance | $3,100 – $5,800 |
| HeatShield resurfacing (cast-in-place liner restoration) | $1,900 – $4,600 |
| Crown rebuild (concrete or mortar crown, standard cap) | $850 – $1,800 |
| Partial rebuild (top few courses, flue tile, and crown) | $1,800 – $6,500 |
| Full-height rebuild (single-story, standard masonry) | $9,000 – $14,000 |
| Gelco chimney cap replacement (multi-flue, stainless) | $275 – $650 |
| Flue tile relining (Clay or Famco components where applicable) | $1,200 – $3,400 |
| Pre-install inspection and camera scope | $150 – $350 (credited toward work) |
Two things push these numbers up more than anything else: access and condition. On the tight lots off Steiner and Pierce, we sometimes can’t get a truck close enough to stage a full rebuild, which adds labor. And on a 1905 Edwardian, the brick itself is often softer than modern masonry – once the crown cracks, water gets in and the top courses spall (flake and crumble) faster than on newer construction.
What drops the cost: catching a failing crown before it lets water through, and choosing HeatShield resurfacing instead of a full liner replacement when the existing flue is still structurally sound. HeatShield is a cast-in-place resurfacing system applied by certified applicators – it seals joints and smooths the interior without tearing out the old flute, and it’s a job most sweep-only crews aren’t set up to do.
Why the material matters
We install DuraFlex liner systems, Gelco caps, and Copperfield components – professional-spec parts you won’t find at a big-box store. The liner is the single most important safety component in your chimney, and it’s not a place to save $400 on a retail product that wasn’t designed for this flue. Built to spec, not built to last until we leave.
What Affects Chimney Liner & Rebuild Pricing in Alamo Square
- Age and brick condition. The 1890-1915 Victorian and Edwardian masonry here means softer brick, more spalling, and more frequent crown failure than you’d see on a post-war home. A flue that’s been rained into for decades needs more repair before a liner can go in.
- Flue liner type. A single-flue flexible liner is the simplest job. An insulated system that vents a gas insert or wood appliance runs higher, and it requires the right component match – Famco venting components show up here when an appliance tie-in is part of the work.
- Access and staging. Alamo Square houses sit shoulder to shoulder. When we can’t set up a lift or stage materials near the roofline, labor climbs. Add $300 to $900 on the tighter blocks.
- Height and pitch. A two-story flue on a steep roof costs more to reach safely than a single-story flue on a flat curb. Rebuild labor scales directly with how many courses come off and how safely we can work.
- Liner vs. resurfacing decision. If the existing flue is intact but the joints are failing, HeatShield resurfacing often saves a homeowner $800 to $1,500 over a full reline. If the flue tile is cracked through, resurfacing won’t hold – the liner has to go in.
- Cap and weatherproofing. A missing or damaged cap is the leading cause of the water damage we find on these blocks. A Gelco cap replacement is $275 to $650 and prevents thousands in rebuild cost later.
We also explain the difference between what’s structural and what’s cosmetic before we quote. A lot of chimney estimates pad in work that isn’t actually necessary. Our quote is itemized, and we tell you which repairs are urgent and which can wait a season.
How to Save on Chimney Liner & Rebuild
The single biggest cost-saver is timing. A $300 crown repair caught early prevents a $4,000 partial rebuild two years later. Here’s how we’d approach it if this were our own home:
- Book a sweep before the wet season. A professional sweep clears creosote and lets us inspect the flue joints while the weather’s calm. Catching a hairline crack now is cheaper than fixing it after a winter of rain.
- Get the cap fixed today. A Gelco or Copperfield cap keeps water out and stops the damage that drives rebuild cost. It’s the cheapest insurance on the whole system.
- Ask about HeatShield over a full reline. If your flue is structurally intact, resurfacing can save $800 to $1,500. We’ll tell you honestly whether it applies.
- Bundle the sweep, the repair, and the dryer vent check. One call covers the sweep, the vent, and the repair. Your dryer vent is a fire risk your chimney sweep should also check – catching it in the same visit keeps the whole system safe without a second contractor’s trip charge.
- Ask for a free estimate and an itemized quote. We itemize so you can see what’s urgent and what isn’t. Call (833) 620-7061 to schedule.
One note on safety before we go further: the liner and rebuild work in this guide involves high-tension structural masonry, roofline access, and the flue itself. It’s not a DIY category. A liner installed out of spec can fail silently and vent combustion gases into the living space. We’re state-licensed, insured, and a real expert flags the danger – this is work for a trained crew.
FAQs – Chimney Liner & Rebuild Cost
How much does a chimney liner cost in Alamo Square?
A standard single-flue flexible liner in Alamo Square runs $2,400 to $4,200, and an insulated system for a gas or wood appliance runs $3,100 to $5,800. The price difference is driven by flue height, liner insulation, and whether the flue needs prep work first. Call (833) 620-7061 for an exact quote – estimates are free.
Is it cheaper to repair or replace a chimney liner?
Repair is cheaper when the flue is intact: HeatShield resurfacing at $1,900 to $4,600 usually beats a full reline at $2,400 to $5,800. Replacement wins when the clay tile is cracked through or the flue has lost structural integrity. We scope the flue with a camera and tell you which side you’re on before recommending work. Call (833) 620-7061 to schedule the inspection.
How much does a chimney rebuild cost in Alamo Square?
A partial rebuild here runs $1,800 to $6,500, and a full-height rebuild on a single-story Victorian or Edwardian flue runs $9,000 to $14,000. The older brick stock around Alamo Square Park often needs more repair than newer homes, so the top of the range is common. Estimates are free – call (833) 620-7061.
Can you come out today to look at my chimney?
Same-day and emergency availability isn’t something we guarantee, but we do keep the schedule tight and can often get an estimate scheduled within a few business days. Call (833) 620-7061 and we’ll find the soonest opening for your address.
Do I really need a chimney sweep, or can I skip it?
You need the sweep, and the cost is small next to a rebuild: a professional sweep runs a fraction of the $2,400-plus liner price and is the inspection that catches the failures before they become expensive. Creosote buildup is the leading cause of house fires from wood-burning flues, and a sweep is also when we check the dryer vent – a fire risk most chimney companies ignore. One call covers the sweep, the vent, and the repair.

What Our Customers Say
"Crown was cracked and taking water. Repaired it rather than quoting a rebuild, which the previous company had pushed hard for."
- Ernesto Ramirez"Good work. The written inspection report took about a week to arrive after I asked for it, which was slower than I expected."
- Emily Rhodes"Fireplace had never drawn properly since we moved in. He found the damper was only opening halfway due to a bent linkage and fixed it in ten minutes."
