Fast, Reliable Chimney Liner & Rebuild Across Kenton
Chimney liner installation and rebuild work in Kenton typically runs $2,800–$8,500 depending on whether we’re dropping a stainless steel liner into a sound stack or rebuilding spalled brick from the roofline up. Most Kenton jobs are completed in 1–3 days once materials are on-site, and Larry Peterson personally handles the inspection and installation — not a subcontractor you’ve never met.
We’ve been crossing the Columbia River to work on Kenton chimneys for 14 years, and we know the neighborhood’s quirks: those 1920s worker cottages on Denver Avenue, the bungalows tucked between Interstate 5 and the Columbia River Slough, the persistent damp that settles over ZIP 97217 from October through May. If your chimney’s smoking, your basement smells like soot, or a home inspector flagged your flue, call us at (888) 916-8797. We’ll come out, camera the flue, and tell you exactly what’s happening inside that brick stack.
Why Sequoia Chimney Sweep Vancouver Is Kenton’s Preferred Chimney Liner & Rebuild Company
Kenton isn’t a generic Portland neighborhood to us. We’ve rebuilt liners on N Argyle Street, capped chimneys near Kenton Park, and traced mysterious draft failures back to abandoned coal thimbles in basements off N Denver Avenue. That local pattern recognition matters when your chimney was built in 1923 and nobody’s looked inside it since the Reagan administration.
Our 664 verified reviews at 4.8 stars include plenty from Kenton and North Portland homeowners who found us after another company couldn’t solve a persistent problem. Often it was the hidden thimble. Sometimes it was an oversized clay flue venting a modern gas insert that was never properly relined. Larry shows up personally, runs the camera himself, and explains what he’s seeing on the monitor — no jargon, no pressure.
Response time to Kenton is typically same-day or next-day for inspections. We’re based in Vancouver, WA, which means we’re not fighting downtown Portland traffic to reach you; we come down Interstate 5 or across the Interstate Bridge and can usually be at a Kenton address within 30–45 minutes. For emergency situations — a smoking fireplace, a suspected gas leak from a compromised flue, or visible structural cracking after a freeze-thaw cycle — we prioritize Kenton calls because we know how fast moisture damage accelerates in this zip code.
Our Chimney Liner & Rebuild Services in Kenton
Stainless Steel Liner Installation
For Kenton chimneys with sound exterior brick but deteriorated clay flue tiles, a stainless steel liner is often the right fix. We install Olympia Chimney and DuraFlex rigid and flexible systems sized precisely to your appliance — critical in Kenton, where original 8×8 clay flues are dramatically oversized for modern gas inserts and cause acidic condensation that destroys mortar from the inside. A properly sized stainless liner runs hotter, drafts better, and carries a lifetime warranty in many configurations. Typical Kenton installation: $2,800–$4,500 for a single-flue system.
Flexible Liner Installation
Kenton’s 1910s–1930s chimneys often have offsets, corbelling, or slight lean that makes rigid stainless impossible to drop. That’s where flexible DuraFlex liners shine — they navigate bends while maintaining the same corrosion resistance and proper sizing. We see this constantly on Kenton’s Craftsman bungalows where the chimney was built tight to the structure with no straight shot. Flexible liner jobs in Kenton generally fall between $3,200–$5,000 depending on length and access. Larry handles the measuring and fit personally; a sloppy flex installation that gaps at the top plate is worse than no liner at all.
Liner Replacement
When an existing liner has failed — cracked clay tiles, corroded old stainless, or a deteriorated poured-in-place system — we extract and replace. In Kenton, we frequently find that a 1990s liner was never properly sealed at the thimble or top plate, or that the original clay tiles were damaged during a previous gas conversion. We use HeatShield cerfractory foam for resurfacing sound but pitted clay, or full replacement with new stainless when the damage is too extensive. Replacement jobs in Kenton start around $3,500 and can reach $6,500 if we’re also addressing hidden thimble leaks or smoke chamber issues.
Partial Chimney Rebuild
Not every Kenton chimney needs to come down to the roofline. When the upper courses are spalled and the lower stack is sound, we rebuild from the roof up — typically 4–8 courses plus a new crown and proper flashing. This is common on Kenton homes where the top of the chimney sits above the roofline in constant wind-driven rain off the Columbia River Slough. Partial rebuilds in Kenton run $4,500–$7,500 depending on brick matching, scaffold requirements, and whether we’re also dropping a new liner. We source matching brick when possible and pour concrete crowns with proper drip edges, not the slapped-on mortar caps that fail in two Portland winters.

Trusted Brands We Service in Kenton
We don’t use generic hardware-store materials on Kenton chimneys. For liners, we specify DuraFlex flexible stainless and Olympia Chimney rigid systems — both carry UL listings and proper sizing charts for your appliance. For resurfacing and sealing, HeatShield cerfractory foam lets us restore pitted clay flues without full replacement when the damage is moderate. For caps, dampers, and top-sealing dampers, we use Famco and Copperfield components that we keep in stock for fast turnaround. Because we’re across the river in Vancouver, we can usually source specialty Kenton jobs without the multi-week delays that plague contractors who order drop-ship. Larry specifies every component before we start; you’ll know exactly what’s going into your chimney.
Common Chimney Liner & Rebuild Problems We See in Kenton Homes
- Oversized clay-tile flues venting modern gas inserts. Your 1925 Kenton bungalow was built with an 8×8 or larger flue for a coal furnace or open fireplace. That insert you had installed in 2015 needs a 6-inch liner. Without one, flue gases cool too fast, condense into sulfuric acid, and eat your mortar joints from the inside — damage you’ll never see until the camera goes down.
- Uncapped side-entering thimbles from abandoned coal furnaces. That rusted iron door in your basement wall? It’s a thimble that once connected your chimney to a coal heater. When left open, it creates a hidden bypass that pulls combustion gases into your basement instead of up the flue. We’ve found this on Denver Avenue, on N Argyle, and throughout Kenton’s 97217 core — it’s a legacy problem virtually unknown in post-1950 neighborhoods.
- Freeze-thaw damage accelerated by Columbia Slough moisture. Kenton’s proximity to the Slough keeps ambient humidity higher than neighborhoods to the south. Brick that looks sound in August can be saturated and vulnerable by January. A Level II camera inspection catches spalling and cracked mortar that a basic visual sweep misses entirely.
- Improper 1980s gas conversions with no liner at all. We still find Kenton chimneys where a gas insert was simply shoved into the firebox with a short connector pipe, leaving the original oversized flue to handle venting. The resulting condensation has been silently destroying the chimney for 40 years. On a Craftsman bungalow on Denver Avenue, we pulled a rusted one-piece stove pipe from exactly this scenario — the original clay-tile flue was 8×8, way too big for the new heater, causing condensation that spalled the interior brick. We lined it with a DuraFlex 6-inch flexible liner and sealed the abandoned coal-furnace thimble with HeatShield cement, restoring draft and safety.

Factors that push Kenton jobs toward the higher end: chimneys over 25 feet tall (common on Kenton’s two-story bungalows), difficult roof access on steep pitches, the need to match historic brick, and hidden thimble or smoke chamber issues discovered during camera inspection. We price these honestly upfront, not as “change orders” after we’ve started.

FAQs — Chimney Liner & Rebuild in Kenton
Probably not — smoking with a gas insert usually points to an oversized flue, poor draft, or a hidden thimble leak, not structural failure. We camera the flue first. If the exterior brick is sound and the interior damage is limited to the flue surface, a properly sized stainless or flexible liner plus thimble sealing solves the problem for $3,000–$5,500. Call (888) 916-8797 and we’ll camera it — estimates are free.
That’s a coal-furnace thimble, original to your 1910s–1930s Kenton home. It was the connection point between your basement heater and the chimney flue. When left open after the furnace was removed, it becomes a hidden bypass that vents combustion gases into your basement instead of up the stack. We seal these with HeatShield cerfractory cement or proper blocking during liner installation — it’s a critical safety step that many contractors miss. Call (888) 916-8797 if you’ve spotted one.
A quality 316Ti or 304 stainless liner properly installed with correct appliance sizing lasts 20+ years, even in Kenton’s damp conditions. The key is proper sizing — an oversized liner that runs too cool will condense acidic moisture and corrode prematurely. We size every liner to the appliance using NFPA 211 standards, not guesswork. Our DuraFlex and Olympia Chimney systems carry manufacturer warranties that reflect this lifespan. For a specific assessment of your setup, call (888) 916-8797.
We don’t recommend it. Kenton’s freeze-thaw cycles and constant moisture mean surface patching with generic mortar fails within one to two winters — and climbing a ladder to work on a chimney above roofline is genuinely dangerous without proper fall protection and scaffold. The cracks you see are often symptoms of deeper spalling or liner failure inside. We use proper crown pours with expansion joints and drip edges, and we camera the flue while we’re up there. For safe, lasting repair, call (888) 916-8797.
Not necessarily. We’ve saved plenty of Kenton’s 1920s chimneys with partial rebuilds and new liners when the foundation and lower stack are sound. The deciding factors are: foundation integrity (no settling or separation from the house), lower brick condition below the roofline, and whether the flue can be properly lined. Larry assesses all three during our Level II inspection. Full rebuilds are reserved for chimneys with structural cracking, significant lean, or foundation failure — maybe 20% of the century-old chimneys we see. Call (888) 916-8797 for an honest evaluation.
