Fast, Reliable Chimney Repair Across North Portland
Chimney repair in North Portland typically runs $280-$1,800 depending on scope, and most jobs our Chimney Repair team completes in a single visit with same-day scheduling available. We’ve been working the 97203 ZIP and surrounding North Portland neighborhoods since 1984, so when a St. Johns bungalow owner calls with spalled brick or a leaking flue, we’re already familiar with the house type before we pull up.
North Portland sits on that low peninsula between the Willamette and Columbia rivers, and the fog that rolls in off the water here hits chimneys differently than it does in drier eastside neighborhoods. We’ve watched mortar joints on century-old stacks in Kenton and St. Johns deteriorate faster than identical construction in Hawthorne or Laurelhurst, simply because the ambient humidity stays higher, longer, through Portland’s wet season. That local pattern matters when we’re deciding whether a chimney needs repointing now or can wait until next year. Call (844) 803-1545 and a live person will answer, 24 hours a day.
Why Hearthstone Chimney Co. Is North Portland’s Preferred Chimney Repair Company
We’ve swept and repaired chimneys in North Portland for over 42 years. Russell Haines founded this company in 1984, and our technicians have worked on the original brick stacks of Craftsman bungalows from N Lombard to N Philadelphia long enough to recognize the construction quirks of specific builders and eras.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. Homeowners in the St. Johns and Kenton areas tell us this matters because they’ve dealt with contractors who couldn’t explain what was actually wrong. We document like an engineer and explain like a craftsman.
Calls are answered by a live person, 24 hours a day, 7 days a week. Not a voicemail, not a callback queue. When a chimney leak shows up during a December storm in North Portland, you get a human who can dispatch a background-checked, uniformed technician, usually same day. Most repairs are completed in a single visit with no-hassle upfront pricing, so the number on the estimate is the number on the invoice.
Every job carries our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork, no arguing. That’s been our standard since 1984, and it’s why homeowners who’ve used us once tend to keep our number near the phone.
Our Chimney Repair Services in North Portland
Mortar Repointing
The pre-WWII brick chimneys dominating North Portland’s 97203 housing stock were built with lime-based mortars that soften and erode over 80 to 100 years of wet winters. We grind out deteriorated joints to proper depth and repoint with color-matched, breathable mortar that moves with the original brick instead of trapping moisture. In St. Johns, where many chimneys still carry their original 1910s-1930s construction, this is often the difference between a repair that lasts 25 years and one that fails in five.
Spalling Brick Repair
Spalling, the flaking and crumbling of brick faces, accelerates in North Portland’s river-humid climate where chimneys absorb more moisture per season than identical construction in drier zip codes. Once the freeze-thaw cycle of a Portland winter sets in, saturated brick faces pop off in layers. We remove damaged units, source matching replacement brick where possible, and address the underlying moisture intrusion, often with Chimney Cap & Crown in North Portland work to prevent recurrence.
Chimney Waterproofing
Waterproofing a North Portland chimney requires breathable, vapor-permeable sealers, not the hardware-store coatings that trap moisture inside. We apply professional-grade treatments from HeatShield and Famco that allow the stack to exhale while shedding rain. Given the extended wet season here, October through April, this treatment pays for itself by preventing the spalling and mortar decay that would otherwise require rebuild-level intervention within a few years.
Flashing Repair
Step flashing and counterflashing around chimney penetrations are common leak sources in North Portland’s older homes, where rooflines have settled and original flashing has corroded or pulled away. We fabricate and install custom flashing with proper integration into existing roofing, using materials from Olympia Chimney and Gelco that match the professional grade of our liner and cap work. A proper flashing repair stops the ceiling stains that homeowners near N Philadelphia and N Lombard often discover only after a heavy winter rain.

Trusted Brands We Service in North Portland
We stock and install professional-grade materials from HeatShield, Gelco, Olympia Chimney, and Famco, not builder-grade substitutes that fail early. For North Portland homeowners with aging chimneys originally built for coal ranges and later converted to wood or gas, this matters because mismatched flue diameters and deteriorated liners require materials that meet current code without compromising the original masonry. Our warehouse carries common liner diameters and flashing configurations, so most North Portland repairs don’t wait on special orders. When we quote a job, we’re quoting with parts we can source quickly, not theoretical availability.
Common Chimney Repair Problems We See in North Portland Homes
- Cracked clay tile liners in unrelined single-wythe stacks. The 1910s-1930s bungalows and foursquares of St. Johns and Kenton were built with chimneys sized for coal or wood stoves, never professionally relined. A century later, those terra-cotta flue tiles are cracked, offset, or missing chunks, creating fire and carbon monoxide hazards that our Level-2 camera inspections document with photos you can see.
- Freeze-thaw mortar destruction. North Portland’s river-humid microclimate means chimneys here absorb more moisture than identical construction in drier eastside neighborhoods. When temperatures drop below freezing, that moisture expands, popping mortar joints and spalling brick faces at a rate that makes tuckpointing a near-universal need on homes past the 80-year mark.
- Glazed creosote buildup in underused fireplaces. The damp, cool conditions of North Portland’s fall and winter promote faster glazed-creosote formation even in fireplaces burned only on occasional evenings. This hard, tar-like deposit is more flammable than fluffy soot and requires professional removal, not DIY brushing.
- Flue diameter and height mismatches from mid-century appliance conversions. Many St. Johns bungalows had their chimneys converted from coal ranges to wood inserts or gas appliances in the 1950s-1970s without proper relining or height adjustments. The resulting draft problems and code violations are a recurring issue our technicians encounter street after street in the older blocks near N Lombard.

Base labor rates are consistent across our Portland service area, but North Portland’s older housing stock often requires more extensive repair than newer construction. A century-old St. Johns chimney with original unrelined brick typically needs more intervention than a 1990s stack in Bethany or Cedar Mill. That said, our $50 off any repair over $250 and free second opinion offers apply everywhere we serve. Call (844) 803-1545 for an exact quote on your specific chimney.
