Fast, Reliable Chimney Repair Across Lents
Chimney repair in Lents typically runs $450–$2,800 depending on scope, and most jobs are completed in a single visit with Larry Peterson personally overseeing the work. We’re across the river in Vancouver and regularly serve the 97266 ZIP, usually arriving within 45 minutes to an hour for Lents calls.

Call (888) 916-8797 for a free estimate.
We’ve worked on enough Lents chimneys to know the neighborhood’s patterns. The pre-WWII housing stock along SE Foster Road, SE 92nd Avenue, and the streets bordering Johnson Creek carries original masonry that most homeowners have never had professionally inspected. Larry shows up personally, assesses what you’ve got, and handles the repair start to finish — no subcontractors, no handoffs.
Why Sequoia Chimney Sweep Vancouver Is Lents’s Preferred Chimney Repair Company
Our Chimney Repair team has built a reputation in Lents through fourteen years of showing up when we say we will and fixing what others miss. We’ve earned 664 verified reviews at a 4.8-star rating — one of the most reviewed chimney specialists in the Portland-Vancouver market — and a significant portion of those come from Lents homeowners who found us after a generalist contractor couldn’t solve their problem.
Larry Peterson serves as both owner and lead technician on every job. That means the person quoting your repair is the same person performing or directly supervising the work. For Lents residents dealing with aging, unlined chimneys in 1920s bungalows, this accountability matters. We’ve seen too many cases where a subcontractor crew repointed mortar without addressing the underlying moisture source, only to have the same spalling return within two winters.
Response time to Lents is consistently under an hour from our Vancouver base. We know the crossing points, we know when Foster Road backs up, and we schedule accordingly. For chimney issues that involve active water intrusion or compromised liner integrity, that speed can prevent further masonry damage during Portland’s wet season.
Our Chimney Repair Services in Lents
Mortar Repointing
Mortar repointing in Lents runs $18–$28 per square foot of joint surface, with most craftsman bungalows needing $650–$1,400 of work. The original lime-based mortar in 1920s–1940s Lents homes has typically deteriorated to sand after ninety-plus years of Pacific Northwest moisture cycling. We grind out the failed joint to proper depth and repoint with color-matched, breathable mortar that accommodates the thermal movement these older chimneys experience. On SE Harold Street last spring, we repointed a 1932 chimney where the previous owner had used standard Portland cement — a harder material that trapped moisture and accelerated the very spalling it was meant to prevent.
Spalling Brick Repair
Spalling brick repair in Lents typically costs $800–$2,200 depending on how many courses are affected and whether the flue liner requires replacement. Portland’s wet-season firing pattern — burning wood during months of highest ambient moisture — drives water deep into porous brick, where freeze-thaw cycles pop the face off. Lents’s single-wythe chimneys are especially vulnerable because they lack the thermal mass and drainage pathways of double-wall construction. We remove spalled units, source matching replacement brick where possible, and address the moisture source rather than just the symptom. Larry often finds that Lents homeowners have lived with spalling for years, assuming it’s cosmetic until we show them the liner damage it’s masking.
Chimney Waterproofing
Chimney waterproofing in Lents runs $350–$750 for standard applications, with floodplain-adjacent properties sometimes requiring additional base sealing at $200–$400. This is where Lents’s geography becomes critical. The Johnson Creek corridor creates chronic ground saturation that wicks upward through chimney bases — we’ve found advanced efflorescence and structural cracking in homes within three blocks of the creek that homeowners had dismissed as “a little white powder.” We apply Gelco’s vapor-permeable waterproofing to vertical surfaces, allowing the chimney to breathe while shedding liquid water, and specify additional base treatment where wicking is established. For properties near the creek, this isn’t optional maintenance — it’s structural protection.
Flashing Repair
Flashing repair in Lents costs $275–$550 for standard chimney-to-roof interfaces, with complex intersecting rooflines on Lents’s older homes sometimes reaching $700–$950. The original step flashings on pre-WWII bungalows were often galvanized steel that has corroded through, or were installed without proper counterflashing integration. Portland’s driving rains exploit these gaps relentlessly. We fabricate custom flashings on site to match your roof pitch and chimney configuration, using materials compatible with your existing roofing system. On a 1926 cottage near SE 82nd Avenue, we discovered that three previous “repairs” had simply caulked over rotted flashing — a $12 tube of sealant hiding $2,400 in ongoing water damage to the roof deck and framing.

Trusted Brands We Service in Lents
We stock and install professional-grade materials that match the demands of Lents’s aging chimney stock. For stainless steel liner installations and rebuilds, we specify DuraFlex and Olympia Chimney components — both are trade-trusted for their corrosion resistance in wet-climate applications. For waterproofing and resurfacing, we use Gelco’s vapor-permeable systems and HeatShield’s cerfractory resurfacing product for restoring deteriorated flue surfaces without full liner replacement. Famco and Copperfield hardware round out our cap, crown, and ventilation accessories. We carry common sizes in stock, which means most Lents repairs don’t wait on parts. When you’re dealing with an active leak or a heating season emergency, that turnaround matters.
Common Chimney Repair Problems We See in Lents Homes
- Freeze-thaw spalling on 1920s single-wythe chimneys. Portland’s wet season moisture penetrates porous brick, then expands when temperatures drop below freezing. Lents’s original unlined chimneys lack the thermal protection that would mitigate this cycle, so we see advanced face spalling by the time most homeowners notice.
- Flood-wicking efflorescence and cracking near Johnson Creek. Ground saturation migrates upward through chimney bases, depositing salt crystals and undermining mortar bonds. Homeowners frequently mistake this for a cosmetic issue until we demonstrate the structural cracking and compromised liner integrity it’s signaling.
- Crumbling mortar joints and missing caps on never-inspected chimneys. Lents’s deferred-maintenance history means many chimneys have gone decades without professional evaluation. The original clay caps have often deteriorated entirely, allowing direct water entry into the flue system.
- Incompatible Portland cement repairs from previous owners. Hard, non-breathable mortar traps moisture against soft historic brick, accelerating deterioration. We remove these patches as part of proper repointing work.

FAQs — Chimney Repair in Lents
The white powder is efflorescence — salt deposits left when moisture migrates through masonry and evaporates at the surface. In Lents, the Johnson Creek floodplain creates chronic ground saturation that wicks upward through chimney bases, especially in homes within a few blocks of the creek. This same moisture migration causes the structural cracking that homeowners often mistake for settling or cosmetic damage. We’ve found bottom courses in this pocket that have lost significant structural integrity while the homeowner was planning to “touch up the paint.” Call (888) 916-8797 if you’re seeing this pattern — we’ll assess whether the liner has been compromised.
Yes, most 1940s single-wythe chimneys in Lents can be fully repaired in one trip if the damage is limited to exterior masonry and the flue liner is intact or replaceable with our stocked DuraFlex components. On SE Foster Road near Johnson Creek, we repointed a 1940s cottage chimney where moisture migration had spalled the bottom four courses. We installed a DuraFlex stainless liner and sealed the base with Gelco waterproofing to break the wicking cycle — a single-trip fix for a self-reliant homeowner. Complex rebuilds or custom brick matching may require a second visit, but we’ll tell you that upfront during your free estimate.
Most Lents craftsman bungalows with original unlined or single-wythe clay tile chimneys need a stainless steel liner to meet current safety standards, especially if you’re actively using the fireplace or stove. The original construction often lacked any liner, or the clay tiles have deteriorated after ninety-plus years of thermal cycling and moisture exposure. Portland’s wet-season burning pattern — firing during months of highest ambient moisture — accelerates creosote accumulation and liner deterioration. We install DuraFlex and Olympia Chimney stainless liners sized to your appliance and flue configuration. The $1,800–$3,400 investment protects both safety and masonry longevity.
Portland’s wet season — October through April — is simultaneously the primary heating season, which creates a damaging combination for Lents chimneys. Residents fire wood-burning appliances during months of highest ambient moisture, promoting incomplete combustion, accelerated creosote layering, and rapid spalling of brick and mortar as freeze-thaw cycles attack water-saturated masonry. We schedule exterior masonry repairs during drier windows when possible, but waterproofing and liner work can proceed year-round. Emergency repairs for active leaks or compromised liners happen regardless of weather. If you’re entering heating season with visible masonry damage, call (888) 916-8797 — delaying through winter often multiplies the damage.
We specify DuraFlex and Olympia Chimney for stainless steel liner components in rebuilds, Gelco for waterproofing and protective coatings, and HeatShield for cerfractory flue resurfacing where full liner replacement isn’t required. Famco and Copperfield provide our cap, crown, and ventilation hardware. These are trade-trusted brands we’ve used across fourteen years and hundreds of chimneys — not generic materials sourced from hardware store shelves. For Lents’s moisture-challenged environment, the corrosion resistance and vapor permeability of these specific product lines matter. Call (888) 916-8797 to discuss what your chimney needs.
