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 Repair Cost in Portland?
Chimney repair in Portland typically costs $275 to $1,800 depending on what’s wrong, with most common fixes landing between $400 and $900. A simple crown repair runs $300 to $600, a partial flue reline runs $1,200 to $1,800, and a full rebuild sits well above that. The written estimate sets the final price, and we never charge for the estimate itself.
We’re Belmont Chimney Cleaning, and we handle chimney sweeping, dryer vent cleaning, and chimney repair as one service. Our technicians have up to 9 years of experience, and we stock the professional-trade materials that chimney work actually requires: DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. The ranges below reflect what Portland homeowners see when a chimney inspection turns up something that needs fixing.
Chimney Repair Cost Breakdown (2026)
These figures cover the Portland metro, where the winter rain and the age of the housing stock both shape what we find. Every job is different, and the written estimate you get after we look at your chimney is the number that matters.
| Repair | Typical range | What’s involved |
|---|---|---|
| Crown repair (cracked or spalling) | $300 – $650 | Chip out the damaged crown, patch or recast the concrete, seal the seam at the flue |
| Chimney cap replacement | $150 – $400 | New stainless or copper cap fitted to the flue, sized for the flue opening |
| Flashing repair or replacement | $250 – $750 | Reseal or rebuild the metal flashing where the chimney meets the roof |
| Mortar joint repointing | $400 – $1,200 | Grind out failing mortar and repack the joints, priced by the section |
| Partial flue reline (one section) | $1,200 – $1,800 | DuraFlex stainless liner run through a section of flue, insulated where needed |
| Full flue reline (entire run) | $1,800 – $4,500 | Full-length DuraFlex liner, connected to the appliance and capped at both ends |
| HeatShield flue resurfacing | $900 – $2,400 | Ceramic resurfacing compound applied to deteriorating flue tiles, restoring the flue without a rebuild |
| Chimney rebuild (above the roof) | $6,000 – $15,000+ | Tear down and rebuild the masonry above the roofline; higher work costs more |
The cheapest fix isn’t always the cheapest outcome. A small crown crack caught early costs a few hundred dollars. Left for another rainy season, water gets into the masonry, the freeze-thaw cycle in Portland’s occasional cold snaps widens the crack, and the job becomes repointing or a partial rebuild. That gap is the single biggest reason two chimneys in similar condition end up with wildly different estimates.
The line items above break out by what’s damaged. In practice, work clusters around those individual repairs, but the $275-baseline jobs are usually small and the reline jobs carry the most weight. That’s why we quote the whole job after we’ve seen it, not a flat number over the phone.
What drives the cost up or down
Access is the big one. A chimney on a steep Portland roof or set back from the ridge needs more setup, which adds to the bill. Material choice matters too: a properly sized DuraFlex liner and the right HeatShield compound cost more upfront than generic substitutes, but they outlast them. And what’s actually wrong when we get there? A cracked crown is a quick fix. A flue that’s been letting water in for years is a different story.
What Affects Chimney Repair Pricing in Portland
- The weather. Portland’s wet winters are hard on masonry. Water finds hairline cracks, freezes on the occasional cold night, and ejects the mortar. Chimneys here tend to need crown and flashing attention more often than chimneys in dry climates, and that’s the bulk of the repair calls we see.
- The age of the house. A lot of Portland housing stock is older than the chimney codes that govern relining today. A chimney that’s never had a properly sized liner, or has old clay tiles that have cracked, needs a reline rather than a patch. That’s the difference between a few hundred dollars and a couple of thousand.
- The masonry condition. Spalling brick, missing mortar, and a disintegrated crown are three separate problems with three separate fixes. When they overlap, the estimate climbs. Repointing first and repairing the crown after is cheaper than rebuilding, but only if the brick is still sound.
- The flue setup. Open masonry flues handle damage differently than a flue serving a wood stove or insert. An insert changes the liner requirements, and liners for inserts have their own sizing and insulation rules.
- How much we have to take apart. The more of the chimney structure that needs opening up, the higher the labor. That’s why we measure before we quote, not after.
How to Save on Chimney Repair
The best saving is catching the problem before it grows. A small crown crack repaired today costs less than the repointing it will trigger later. Get the chimney looked at before the first wet fall weather rather than in the middle of it, and you’ll spend less on the work itself because it’s scheduled rather than reactive.
Here’s what actually moves the number:
- Repair, don’t rebuild, when the masonry is sound. Repointing and a new crown will buy you years over a full rebuild if the brick core is intact. We can tell you which side of that line you’re on after we look.
- Resurface instead of relining where it works. When the flue tiles are deteriorating but still structurally present, HeatShield resurfacing can restore them without a full liner run. That’s a lot cheaper than a rebuild and it’s a service a lot of sweep-only outfits simply can’t offer.
- Fix the water source, not just the symptom. A new cap and proper flashing prevent the water intrusion that drives most masonry damage. It’s the cheapest work on the list and it protects everything else. Repointing a chimney you haven’t sealed against rain is money spent twice.
- Bundle the work with the sweep. If you’re due for a sweep, have the chimney inspected during it so the repair estimate and the cleaning happen together, not as two separate visits.
Free estimates make the decision simpler. Get the written range first, compare it to the alternatives, and pick the option that fits your chimney rather than the one that fits the phone quote. Call (866) 413-9023 for a free estimate and we’ll tell you what your chimney actually needs.
FAQs – Chimney Repair Cost
What does a typical chimney repair cost in Portland?
Expect $275 to $1,800 for most chimney repairs in Portland, with common fixes like crown repair or flashing sitting in the $300 to $750 range. Large jobs (full relines, rebuilds) go higher. The written estimate after inspection sets the final price. Call (866) 413-9023 for a free quote.
Is it cheaper to repair a chimney flue or reline it?
Repair is cheaper if the damage is limited: $300 to $750 for a flashing or crown fix versus $1,200 to $1,800 for a partial reline. But if the flue tiles are cracked throughout, a repair won’t hold and you’ll spend the reline money on top of the patch. The estimate tells you which case you’re in. Call (866) 413-9023 and we’ll walk you through it.
How much does it cost to fix a chimney leak in Portland?
$250 to $750 typically covers a chimney leak repair, since the leak is usually at the flashing or the crown, not the flue itself. Portland’s wet winters make this one of the more common calls we get. Call (866) 413-9023 for a free estimate.
Can you repair my chimney the same day you inspect it?
Often, yes. If the fix is small (a cap, a crown patch, flashing sealing) we come prepared to do the work, not just report it. Larger jobs like a reline need materials ordered and scheduled. Either way, the estimate is free and the price is set in writing before we start.
Do you handle dryer vent cleaning along with chimney work?
Yes. Dryer vent cleaning is one of our three core services, and lint buildup is a serious fire risk in the same way creosote is. If we’re already out for the chimney, we can clean the dryer vent in the same visit. Call (866) 413-9023 to book both.
