Damascus isn’t like other Portland-area suburbs. Out here in the semi-rural Cascade foothills, your chimney probably works for a living. Wood stoves and masonry fireplaces serve as genuine primary or supplemental heat sources—not decorative accents—meaning chimneys accumulate creosote season after season at rates far higher than in inner suburbs. Larry Peterson, owner and lead technician at Sequoia Chimney Sweep, has spent 14 years repairing chimneys in exactly these conditions. He knows the single-wythe brick stacks on pre-1960s farmhouses along SE 232nd Avenue and the 1970s ranch-style homes near the former Damascus city center. He knows how Damascus’s position slightly upslope and east of Portland’s urban heat island produces more freeze-thaw cycles per winter, relentlessly spalling mortar joints and cracking chimney crowns. When you call us, Larry shows up personally—not a subcontractor you’ve never met.
Why Sequoia Chimney Sweep Vancouver Is Damascus’s Preferred Chimney Repair Company
We’ve earned 664 verified customer reviews averaging 4.8 stars across our service area, including consistent feedback from Damascus homeowners who found us after frustrating experiences with generalist handymen or HVAC companies that sweep chimneys as a side service. Our Chimney Repair team doesn’t split focus across trades—we handle chimneys exclusively, from routine sweeps through full rebuilds.
Larry Peterson serves as both owner and lead technician on every job. That direct accountability matters in Damascus, where chimneys often need nuanced diagnosis: distinguishing between surface spalling and structural failure, identifying whether a smoke smell stems from a cracked flue tile or a mismatched wood-stove thimble. You’re not explaining your setup to a dispatcher who then briefs an unknown crew. You’re talking to the person who will be on your roof.
Our response time to Damascus averages under 45 minutes during standard hours, and we prioritize calls involving active leaks or unsafe burning conditions—common concerns after the first hard freeze hits the foothills. We also understand the local permit landscape: since Damascus disincorporated in 2017 and reverted to unincorporated Clackamas County, structural masonry repairs now fall under Clackamas County Development Services jurisdiction, not Gresham or Portland. Contractors who pull permits by old habit create delays. We file correctly the first time.
Our Chimney Repair Services in Damascus
Spalling Brick Repair
Spalling—where brick faces flake off and mortar crumbles—is epidemic in Damascus. The combination of wet Cascade winters, repeated freeze-thaw cycling, and decades of hard use on original single-wythe brick chimneys leaves masonry deteriorated. We remove damaged material, assess whether the wythe remains structurally sound, and rebuild with mortar formulated for Damascus’s wet climate. Larry recently repaired a single-wythe brick chimney on a 1920s farmhouse on SE 232nd Avenue. The original crown had settled and cracked open, allowing water behind the clay tile flue. After removing loose debris, we installed a new poured concrete crown formed to slope away from the flue, then waterproofed the entire stack with Gelco’s ChimneySaver—this homeowner burns a wood stove as their primary heat source from November through March. The repair cost roughly $2,500 and will prevent further freeze-thaw spalling for decades.
Chimney Waterproofing
At 400–700 feet elevation, Damascus receives heavier winter precipitation than Portland proper. Water finds every entry point: cracked crowns, deteriorated flashing, porous brick. We apply vapor-permeable waterproofing treatments—Gelco’s ChimneySaver is our standard—that allow masonry to breathe while blocking liquid water. This matters particularly for Damascus’s older chimneys that have never been treated and for homes where wood-stove exhaust keeps the stack warm-cool-warm, accelerating condensation cycles inside the brick.
Flashing Repair
Decades-old metal roof flashings corrode from acidic wood smoke and freeze-thaw expansion, letting moisture wick behind the counterflashing and rot the chimney structure from the top down. We see this constantly on ranch-style homes from the 1970s–1990s where original galvanized flashings have reached end of life. We fabricate and install new step flashing, counterflashing, and cricket saddles where needed, sealed with professional-grade materials. The repair stops the leak at its source rather than masking it with sealant that fails within a season.
Mortar Repointing
Repointing—grinding out failed mortar to depth and packing new mortar in proper layers—restores structural integrity without rebuilding. In Damascus, we use Type N or Type S mortar specifically selected for wet-climate durability, not the pre-mixed bagged products some handymen default to. Proper repointing on a single-wythe chimney runs $18–$28 per square foot of wall surface, and it’s often the difference between a chimney that lasts another 30 years and one that requires $8,000+ rebuilding.

Common Chimney Repair Problems We See in Damascus Homes
- Freeze-thaw mortar destruction on pre-1960s farmhouses. Single-wythe brick chimneys on rural properties along SE 232nd Avenue and similar roads absorb moisture through porous brick, then nightly freezing expands that water 9% in volume, popping mortar joints apart. By March, the stack looks like it’s shedding skin.
- Mismatched thimble penetrations from wood-stove retrofits. Modern inserts connected to oversized open-fireplace flues create gaps that allow smoke spillage and accelerate creosote buildup. We see this in 1970s–1990s ranch homes where a previous owner “got a deal” on installation.
- Crown cracks from thermal shock. Damascus homeowners tend to burn intensely on Oregon DEQ wood-burning curtailment days, spiking flue temperatures. The crown—already stressed by freeze-thaw—expands and contracts dramatically, opening cracks that funnel water straight to the flue.
- Flashing failure behind composition roofing. Original flashings on older homes corrode where acidic condensate collects; newer homes suffer from improper integration with architectural shingles. Either way, water stains on ceiling drywall near the chimney breast are the tell.

Several factors push Damascus repairs toward the higher or lower end. Accessibility matters: chimneys on steep-pitch roofs or surrounded by mature Douglas fir require additional setup time. The extent of hidden damage—what we find once we open a wall or remove a deteriorated crown—can expand scope. And permit requirements through Clackamas County Development Services add $150–$400 for structural work. We provide upfront, itemized estimates before beginning any repair. Estimates are free, and we’ll walk you through exactly what your chimney needs versus what can wait.

FAQs — Chimney Repair in Damascus
No—do not operate your wood stove until a qualified chimney professional inspects the stack. Cracked mortar and loose bricks indicate structural compromise that can allow dangerous heat transfer to combustible framing, and gaps in the flue liner may leak carbon monoxide or sparks into wall cavities. We offer same-day safety assessments in Damascus; call (888) 916-8797 and we’ll prioritize your inspection.
Yes. Since Damascus disincorporated in 2017, all structural chimney repairs requiring permits now go through Clackamas County Development Services, not the city of Gresham or Portland. Contractors unfamiliar with this shift sometimes file incorrectly, causing weeks of delay. We pull permits through the proper county channel on every job that requires it.
The most likely cause is a mismatched thimble penetration or an improperly sized liner connecting your insert to an oversized original flue. The gap allows smoke spillage and accelerates creosote buildup. This is one of the most common repair scenarios we encounter in Damascus ranch-style homes with retrofitted stoves. A camera inspection confirms the exact failure point. Call (888) 916-8797 to schedule—estimates are free.
Damascus’s elevation in the Cascade foothills brings more freeze-thaw cycles per winter than Portland’s urban core, and the heavier precipitation saturates masonry more deeply. Combined with wood-stove use that keeps chimneys thermally stressed, mortar simply deteriorates faster here. It’s geography and usage, not imagination.
Caulk fails within one to two seasons on chimney crowns because it can’t accommodate thermal expansion and UV degradation. A proper crown repair requires removing loose material, forming a new concrete or specialized crown coat with positive slope away from the flue, and often applying waterproofing. The temporary “fix” usually traps moisture and accelerates the underlying damage. For a permanent solution in Damascus’s climate, professional repair pays for itself.
