Fast, Reliable Chimney Liner & Rebuild Across North Portland
Chimney liner replacement and chimney rebuilds in North Portland typically cost between $1,800 and $6,500 depending on the scope, and most projects are completed within one to three days. If your St. Johns bungalow or Kenton Craftsman still has its original unlined brick chimney or a deteriorating clay tile liner, you’re looking at a genuine safety issue—not just a maintenance delay.
We’ve been crossing the Interstate Bridge into North Portland for years, and we know the 97203 ZIP well. From the fog-heavy mornings along the Columbia Slough to the dense concentration of pre-war housing in St. Johns, this peninsula’s conditions create chimney problems you won’t find in drier, higher-elevation neighborhoods. When you call (866) 541-8697, you’re reaching James Wilson and our Chimney Liner & Rebuild team—owner-operated, chimney-exclusive, and familiar with the specific failure patterns these 1910s–1940s homes present. We typically schedule North Portland inspections within 48 hours.
Why Horizon Chimney Sweep Washington Is North Portland’s Preferred Chimney Liner & Rebuild Company
Our reputation in North Portland is built on showing up and knowing what we’re looking at. James Wilson has been the lead technician on chimney liner installations and rebuilds for 17 years, and that hands-on experience matters when you’re diagnosing a 1920s American Foursquare with an unlined flue that’s been venting a 1970s wood stove insert for decades. Homeowners in St. Johns and Kenton aren’t calling us for a quick sweep—they’re calling because someone finally told them the truth about what’s inside their chimney.
That truth-telling shows up in our numbers: 1,006 verified customer reviews averaging 4.8 stars. That’s not a handful of cherry-picked testimonials. That’s sustained, repeated trust from homeowners who’ve had us back for annual sweeps, cap replacements, and eventually the liner work they hoped they’d never need. In North Portland specifically, we hear from customers who’ve been through multiple generalist contractors who missed the real problem entirely.
Response time matters when you’re smelling smoke in your living room or noticing water stains around the firebox. We prioritize North Portland calls—typically inspecting within 48 hours and completing liner replacements or partial rebuilds within the same week when materials are in stock. Our familiarity with 97203’s housing stock means we arrive prepared: we know to bring camera equipment for flue inspection, we know to check for single-wall stovepipe connections from the roofline, and we know that “routine cleaning” often uncovers structural issues in these damp, foggy conditions.
Our Chimney Liner & Rebuild Services in North Portland
Stainless Steel Liner Installation
For most North Portland homes with unlined or clay-tile-lined masonry chimneys, a stainless steel liner is the right fix. We install DuraFlex and Olympia Chimney stainless steel liners that handle the wetter, denser smoke this peninsula produces without corroding prematurely. A typical stainless steel liner installation in North Portland runs $2,200–$3,800, including the liner, top plate, insulation, and professional installation. These liners carry a lifetime warranty when properly maintained and are the standard we recommend for wood-burning applications in 97203’s older housing stock.
Flexible Liner Installation
Not every chimney in North Portland runs straight. The offset flues in some St. Johns bungalows—modified over decades by homeowners or unpermitted contractors—need a flexible liner that can navigate bends without tearing. Flexible liners are also the right choice when you’re preserving historic interior masonry and can’t afford the structural disruption of a full rebuild. We source flexible liners from trusted manufacturers and size them precisely to your appliance’s BTU output, not guesswork.
Liner Replacement
Replacement becomes necessary when existing liners—whether clay tile, older stainless, or corrugated flex—have cracked, separated, or corroded beyond safe operation. In North Portland, we replace liners more often than we install them in new construction. The freeze-thaw cycles in this damp microclimate accelerate spalling and joint failure. A liner replacement in North Portland typically costs $1,800–$3,200 for a straightforward swap, rising to $3,500–$4,500 if we need to address crown damage or flue resizing. We recently relined a 1925 American Foursquare on Richmond Avenue in St. Johns where a 1970s-era single-wall stovepipe was directly connected to an unlined flue. The homeowner had no idea the setup was a fire hazard until our camera inspection revealed crumbling clay tiles and glazed creosote. We installed a DuraFlex stainless steel liner and completed a partial rebuild of the chimney crown to restore safe operation.
Partial Chimney Rebuild
Sometimes the liner isn’t the only problem. In North Portland’s 1910s–1940s housing stock, we regularly see chimney crowns eroded by decades of rain and fog, mortar joints ground to powder by freeze-thaw cycles, and brick faces spalled from moisture trapped inside single-wythe construction. A partial rebuild—typically the crown, top few courses of brick, and sometimes the shoulder—runs $2,800–$4,500 in North Portland. This isn’t cosmetic work. A failed crown lets water into the chimney structure, which destroys new liners from the outside in. We use HeatShield and Famco materials where appropriate, and we don’t install a new liner on a chimney that needs crown work without addressing both.

Trusted Brands We Service in North Portland
We don’t use off-brand materials that won’t last through a North Portland winter. Our installations rely on DuraFlex stainless steel liners for their corrosion resistance in wet conditions, Olympia Chimney components for precise fits in older flue dimensions, and Famco termination caps and accessories that handle the persistent moisture this peninsula throws at them. We stock common liner diameters and crown repair materials locally, which means faster turnaround for North Portland homeowners who’ve already waited too long to address a safety issue. When we specify a brand, it’s because we’ve watched it perform in conditions like yours for years—not because it’s the cheapest option our supplier had in stock.
Common Chimney Liner & Rebuild Problems We See in North Portland Homes
- Unlined or clay-tile-lined flues cracking from freeze-thaw cycles. The damp, foggy microclimate in 97203—sitting low between the Willamette River and Columbia Slough—keps masonry chronically moist. When temperatures drop below freezing, that moisture expands and spalls brick and tile from the inside. We’ve pulled out clay tile liners in St. Johns that crumbled at the touch after decades of this cycle.
- Hidden 1970s single-wall stovepipe connections. St. Johns technicians routinely discover single-wall stovepipe running from a wood stove insert directly into an unlined masonry fireplace flue—DIY installations that look intact from the firebox but are visible code violations and active fire hazards when inspected from the roofline. This pattern is specific to this neighborhood’s era and economic history, and it’s dangerous.
- Glazed creosote accelerating liner corrosion. North Portland’s persistent ground fog produces wetter, denser smoke that condenses into third-degree (glazed) creosote faster than in drier neighborhoods. This buildup corrodes flex liners, restricts draft, and creates chimney fire conditions. Regular cleaning helps, but if your liner is already compromised, cleaning alone won’t fix it.
- Crown and shoulder deterioration masking deeper issues. From the ground, a chimney might look like it just needs pointing. From the roof, we often find the crown has disintegrated, the shoulder bricks are loose, and water has been migrating down the flue for years. In North Portland’s climate, this damage progresses faster than homeowners expect.

FAQs — Chimney Liner & Rebuild in North Portland
The pre-WWII housing stock in 97203—Craftsman bungalows, American Foursquares, modest colonials—was built with unlined brick chimneys or clay tile liners that weren’t designed for modern heating appliances. North Portland’s damp, foggy microclimate accelerates mortar erosion and creosote buildup, meaning cleaning visits routinely surface structural problems that no amount of sweeping can fix. When we camera-inspect these flues, we find cracked tiles, eroded mortar, and sometimes active leaks into wall cavities. Call (866) 541-8697 for an inspection—estimates are free.
You can’t tell from the firebox. The dangerous configurations we’ve found in St. Johns—single-wall stovepipe connected directly to unlined masonry flues, undersized connectors, improper clearances—are only visible from the roofline or via chimney camera. If your wood stove was installed during the 1970s energy crisis era, there’s a significant chance it’s not code-compliant. We inspect for this specific pattern regularly in 97203. Call (866) 541-8697 to schedule a camera inspection.
We recommend DuraFlex or Olympia Chimney stainless steel liners for North Portland’s wet climate. Stainless resists the corrosion that wetter, denser smoke causes, and it’s rated for the temperature swings these chimneys experience. Flexible stainless is necessary for offset flues; rigid stainless works for straight runs and offers slightly better draft performance. We size every liner to the specific appliance, not guesswork. Call (866) 541-8697 to discuss your setup.
Exterior brickwork can hide significant crown and shoulder damage. In North Portland’s climate, water infiltration through a cracked crown destroys the chimney from the top down—loosening brick courses, rusting dampers, and eventually compromising any new liner we install. We don’t put new liners into chimneys with failing crowns. A partial rebuild addresses the water entry point and protects your investment. We’ll show you exactly what we find during inspection. Call (866) 541-8697 for a free estimate.
Yes, the City of Portland requires permits for chimney liner installations and rebuilds, and we handle the permit process as part of our project workflow. For homes in 97203 with unpermitted 1970s stove installations, bringing the system up to current code often requires additional documentation. We’ve navigated this process many times in North Portland and can advise on what’s needed for your specific property. Call (866) 541-8697 and we’ll walk through the requirements.
