We know Kenton’s streets well. From the bungalows along Denver Avenue to the worker cottages near Kenton Park, these 1910s–1940s homes weren’t built for modern heating systems. Their chimneys have survived a century of Portland winters, but they’re now facing accelerated deterioration from moisture, freeze-thaw cycling, and in many cases, modifications that created hidden safety hazards. Larry shows up personally on every Kenton job — not a subcontractor you’ve never met.
Why Sequoia Chimney Sweep Vancouver Is Kenton’s Preferred Chimney Repair Company
Our reputation in Kenton was built one chimney at a time. Homeowners here aren’t looking for the cheapest bid — they’re looking for someone who understands what makes their 1920s brick stack different from a 1990s suburban fireplace. We’ve earned 664 verified customer reviews averaging 4.8 stars, and many of those come from North Portland and Kenton residents who found us after a generalist handyman couldn’t diagnose the real problem.
Response time matters in Kenton, especially during the rainy season. We’re typically on-site within 24–48 hours of your call, and we carry common repair materials — including HeatShield refractory mortar, DuraFlex relining components, and Famco flashing stock — so we’re not waiting on parts while your chimney leaks. Larry’s familiarity with Kenton’s specific housing stock means faster diagnosis: he knows to check for abandoned coal-furnace thimbles, oversize flues from gas conversions, and the moisture patterns that develop in chimneys this close to the Columbia River Slough.
That local knowledge translates to accountability. When Larry finishes a repointing job on a Kenton Craftsman, he knows how that chimney was originally built, what shortcuts previous owners may have taken, and what the next decade of wet winters will demand from the repair.
Our Chimney Repair Services in Kenton
Mortar Repointing
Kenton’s original brick chimneys were laid with lime-based mortar that’s now 80–110 years old. Portland’s 36 inches of annual rainfall, concentrated November through March, keeps those mortar joints saturated for months; the freeze-thaw cycles that follow crack and crumble the softened material. We grind out deteriorated mortar to proper depth — typically ¾ inch — and repoint with color-matched, breathable mortar that accommodates the thermal movement these historic stacks experience. On a recent job near N. Schmeer Road, we repointed a 1923 chimney where the original mortar had turned to sand above the roofline, leaving the upper courses structurally compromised.
Spalling Brick Repair
Spalling — the flaking and crumbling of brick faces — is epidemic in Kenton chimneys. The Columbia River Slough keeps ambient humidity elevated year-round compared to drier Portland neighborhoods to the south, and that constant moisture penetration followed by surface freezing pops the brick faces off. We remove spalled units, source matching replacement brick where possible, and address the underlying moisture source before the damage spreads. In Kenton’s historic district, we often pair spalling repair with chimney waterproofing using breathable silane-siloxane sealers that don’t trap moisture inside the masonry.
Chimney Waterproofing
Waterproofing a Kenton chimney isn’t optional — it’s structural preservation. The combination of historic, porous brick and Portland’s prolonged wet season means unprotected chimneys absorb water like a sponge. We apply professional-grade waterproofing agents that allow vapor to escape while blocking liquid water penetration. For Kenton homes with chimneys that have already suffered moisture damage, we often combine waterproofing with crown repair using Copperfield crown seal products, creating a complete moisture defense system.
Flashing Repair
Kenton homes present unique flashing challenges. The 1910s–1940s worker cottages often have low-slope roof intersections and minimal clearance between chimney and roofline, making proper step flashing and counterflashing installation critical. We fabricate and install custom flashing using long-lasting materials that accommodate the thermal expansion differentials between brick and roofing. For townhome chimneys in denser Kenton blocks, our repair methods minimize disruption to neighboring units — we can often complete flashing repairs from roof access without scaffolding that affects adjacent properties.
Chimney Rebuilding
When Kenton chimneys have deteriorated beyond repair — often from years of unchecked moisture damage or seismic stress in Portland’s hazard zone — we perform controlled teardowns and rebuilds using compatible materials and proper structural reinforcement. Larry oversees every phase, from temporary bracing and salvage of original decorative elements to final coursing and cap installation. We recently rebuilt a 1917 chimney on N. Argyle Street where the upper eight courses had separated from the stack, creating an imminent collapse hazard above a busy sidewalk.
Tuckpointing
For Kenton chimneys with historically significant brickwork, we offer traditional tuckpointing — the careful removal of failed mortar and precise replacement to match original joint profiles and color. This is slower work than standard repointing, but it preserves the architectural character that makes Kenton’s housing stock distinctive.

Trusted Brands We Service in Kenton
We don’t use generic hardware-store materials on Kenton chimneys. For relining work, we specify DuraFlex stainless steel liners and HeatShield cerfractory flue sealant — the same products specified by factory-built fireplace manufacturers for repair applications. Our flashing and cap installations rely on Famco and Copperfield components, and when we rebuild crowns or install protective caps on Kenton chimneys, we source Olympia Chimney products rated for the wet, acidic conditions these flues experience. Keeping this inventory stocked locally means Kenton homeowners aren’t waiting two weeks for a special-order part while their chimney leaks into the attic.
Common Chimney Repair Problems We See in Kenton Homes
- Hidden bypass leaks from abandoned coal-furnace thimbles. Kenton’s 1910s–1930s worker cottages frequently have chimneys that served both a fireplace and a side-entering coal furnace through a single brick stack. When the furnace was removed, the lower thimble opening was often left unsealed. We regularly find these hidden bypasses venting combustion gases into basements — a hazard no carbon monoxide detector can fully mitigate.
- Moisture-driven mortar decay accelerated by Columbia River Slough proximity. Kenton’s location keeps relative humidity elevated year-round, and the near-constant moisture saturation softens mortar joints far faster than in drier Portland neighborhoods. By the time homeowners notice interior water stains, the exterior damage is often extensive.
- Oversized clay-tile flues in gas-insert conversions. Many Kenton chimneys were later fitted with gas inserts without proper relining, leaving an oversized clay-tile flue venting an appliance too small to maintain adequate flue gas temperatures. The resulting condensation produces acidic byproducts that deteriorate mortar and flue tiles from the inside out.
- Seismic vulnerability in unreinforced masonry stacks. Portland’s seismic hazard zone designation makes structural integrity a genuine concern for Kenton’s 80–110-year-old brick chimneys. Mortar deterioration, previous partial repairs, and lack of structural reinforcement combine to create collapse risks during seismic events.
We recently repaired a 1925 Craftsman on Denver Avenue where the homeowner complained of smoky odors and poor draft. Our Level II inspection revealed an unsealed coal-furnace thimble in the basement, left behind after a furnace conversion. We closed the opening with a stainless steel block-off plate and relined the flue with HeatShield, restoring proper draft and eliminating the safety hazard.

The extent of hidden damage revealed during inspection is the biggest variable; we’ve opened up repointing jobs to find the inner wythe of brick completely degraded. Material matching for historic brick also affects price — we won’t slap a mismatched repair on a century-old Kenton chimney just to save a few hours.

FAQs — Chimney Repair in Kenton
Kenton’s 1910s–1930s worker cottages were built with chimneys that served both a fireplace and a coal furnace through a single brick stack, and when the furnace was removed, the lower thimble opening was frequently left unsealed. This creates a hidden bypass that vents combustion gases directly into the basement, defeating draft performance and creating carbon monoxide exposure. We identify these with Level II video inspection — call (888) 916-8797 if you’ve never had your Kenton chimney’s lower flue openings verified.
The Slough keeps Kenton’s ambient humidity elevated year-round compared to drier Portland neighborhoods, and this constant moisture accelerates mortar joint deterioration and brick spalling by roughly 30–40% based on our field observations. Freeze-thaw damage is more severe here because bricks never fully dry between saturation events. We account for this in our repair specifications — using more breathable mortars and recommending more frequent inspection intervals for Kenton chimneys than for identical structures inland.
Repointing means carefully grinding out deteriorated mortar to a consistent depth — typically ¾ inch — and replacing it with new mortar matched for strength, color, and breathability to the original lime-based mix. On Kenton’s historic chimneys, we avoid Portland-cement-heavy mortars that are too rigid and trap moisture; instead we specify softer, more compatible mixes. A typical Kenton repointing job takes two to three days and includes thorough inspection of the interior flue condition.
Yes — most Kenton chimneys with gas inserts have oversized original clay-tile flues designed for wood or coal combustion, and the smaller gas appliance cannot maintain flue temperatures high enough to prevent condensation. That condensation produces acidic byproducts that deteriorate mortar and flue tiles. We typically recommend a properly sized DuraFlex stainless steel liner or HeatShield cerfractory resurfacing to match the flue to the appliance. Call (888) 916-8797 for a free assessment of your specific setup.
Portland’s seismic hazard zone designation makes structural integrity a real concern for Kenton’s unreinforced masonry chimneys, many of which are 80–110 years old with degraded mortar. A chimney with significant mortar loss or previous partial repairs can separate from the structure or collapse during seismic activity. We evaluate seismic vulnerability during every Kenton inspection and can recommend structural reinforcement options, including tie-downs and partial rebuilding with reinforced construction, when appropriate.
Yes — for Kenton’s denser housing with shared walls or minimal lot lines, we use roof-access techniques and compact equipment that avoids scaffolding extending onto adjacent properties. Most flashing repairs on townhome chimneys in Kenton are completed from roof level with proper fall protection, and we schedule work to minimize impact on neighboring units. We’ll discuss access specifics during your free estimate.
Spalling — the flaking and crumbling of brick faces — is caused by moisture penetrating the brick, then expanding when it freezes near the surface. In Kenton, the Columbia River Slough’s elevated humidity keeps bricks more saturated year-round, and Portland’s intermittent freeze-thaw cycles are enough to pop the faces off. Once spalling starts, it accelerates as the damaged brick absorbs even more water. We repair spalled areas, replace severely damaged units, and apply breathable waterproofing to break the cycle.
