DuraFlex chimney cleaning and relining in Cedar Hills typically runs $280–$450 for a full sweep with Level 2 inspection, while complete DuraFlex 316L stainless relining of a mid-century ranch chimney averages $2,800–$4,200. We’re Sequoia Chimney Sweep Vancouver — independent specialists, not manufacturer-authorized — and we’ve completed over 200 DuraFlex jobs across the Portland metro since 2015.

Why Cedar Hills Residents Choose Us for DuraFlex Service
We’ve been driving to Cedar Hills since before the 205 interchange was rebuilt, back when most of these ranch homes were hitting their 50-year mark and the phone calls started coming in about smoking fireplaces and water-stained fireboxes. Larry Peterson — owner, lead technician, the person who actually shows up — grew up in Vancouver’s Fruit Valley neighborhood and built his technical foundation through Clark College’s vocational programs. Fourteen years and 664 verified reviews later, he’s still the one climbing the ladder.
Our customers in Cedar Hills don’t find us through billboard ads. They get our number from a neighbor on Cedar Hills Boulevard whose downdraft problem we solved, or from someone on Greenbrier Drive whose 1958 ranch we relined last March. DuraFlex sales & service is what we know, but independence is how we operate — we choose DuraFlex 316L stainless for Pacific Northwest moisture because it outperforms, not because a manufacturer contract requires it. Larry’s signature line around here: “I’d rather tell you what I actually found up there than what you were hoping to hear.” That directness has earned us a 4.8-star rating across those 664 reviews.
We stock DuraFlex liners and fittings locally for same-week turnaround. No waiting on East Coast shipping while your fireplace sits unusable through another wet Cedar Hills weekend — unlike areas such as DuraFlex repair in West Slope, we’re stocked locally.
Common DuraFlex Chimney Cleaning Problems We Solve in Cedar Hills
- Creosote glazing on corrugations from undersized flue openings. The Johnson-McDonald tract homes throughout Cedar Hills were built with a 1:12 flue-to-firebox ratio instead of the proper 1:10. Smoke lingers, cools, and deposits glazed creosote in the ridges of DuraFlex liners — a fire hazard that standard brushing won’t touch. We use rotary poly chains and chemical treatments specific to glazed buildup.
- Corrosion at 304 stainless seams from persistent moisture. Cedar Hills sits in the Tualatin Valley catchment, pulling 37–40 inches of annual rainfall into chimneys that breathe that damp air year-round. We’ve replaced DuraFlex 304 liners that failed at the seam welds after eight years — exactly why we now default to 316L for Cedar Hills relines, with its higher molybdenum content against chloride attack.
- Liner buckling near the crown from freeze-thaw clay tile expansion. Those original clay liners spall and swell during valley hard freezes, pinching the DuraFlex sleeve from the outside. Last winter we found three Cedar Hills chimneys where the liner had kinked at the top course of brick, choking draft to a whisper.
- Improper radial compression creating ovaling at offsets. Installers without mid-century ranch experience often compress DuraFlex too aggressively around the smoke chamber throat, flattening the oval and restricting flow. We measure offset angles before pulling liner — a step that adds twenty minutes and prevents the creosote-trapping restrictions we see in competitor jobs.
- Smoke chamber deterioration hiding behind “clean” flues. Cedar Hills’s 60–70-year-old fireboxes show parge coat failure as standard. A swept flue means nothing if the smoke chamber above it is shedding sandy mortar into the hearth. Our Level 2 Inspection includes smoke chamber video — Chimney Repair in Cedar Hills often starts with what we find there.
DuraFlex Service in Cedar Hills: What Local Conditions Mean for Your Equipment
Cedar Hills was platted by the same developer, the Johnson-McDonald Company, between 1952 and 1965, and every original fireplace in that development shares the same flue-to-firebox ratio defect — a 1:12 instead of the recommended 1:10 — meaning DuraFlex liners for these homes consistently need a full-length ovalizer to correct draft. This isn’t a theoretical problem. Last March we relined a 1958 ranch on Greenbrier Drive where the clay tile liner had spalled into the smoke chamber after a freeze-thaw cycle. We pulled an 8-inch DuraFlex 316L through the crown, and when we opened the damper, the firebox was 20% larger than the flue’s cross-section — the classic Johnson-McDonald undersize. We ovalized the top four feet to coax the draft, and the homeowner’s downdraft complaint vanished.
That pattern repeats block after block through Cedar Hills’s original subdivisions. A technician who doesn’t know this neighborhood’s construction history pulls a round liner, connects it, and leaves — then wonders why the customer calls back smelling smoke in the living room. We’ve documented this failure mode across dozens of Cedar Hills jobs. The Pacific moisture, the aging clay, the undersized flue, the freeze-thaw cycles — they all converge on the same DuraFlex specification: 316L stainless, full-length ovalization, and a crown seal that actually sheds water instead of trapping it.
DuraFlex Models & Products We Service in Cedar Hills
We work with the full DuraFlex product line, specifying by application rather than by price:
- DuraFlex 316L Stainless Steel — our default for Cedar Hills relines. The molybdenum content resists the chloride pitting that kills 304 liners in this rainfall zone. We stock 6″, 7″, and 8″ diameters with standard and extended collars.
- DuraFlex 304 Stainless Steel — specified only for interior gas venting or where budget constraints override longevity concerns. We make the trade-off explicit before ordering.
- DuraFlex High-Temp Aluminized Steel — suitable for gas appliance venting in Cedar Hills’s milder exhaust temperatures. Not for wood-burning hearths.
- DuraFlex Flex-Weight — the lighter-gauge option for straight runs without offsets. Rarely specified in Cedar Hills given the smoke chamber throats and damper offsets common to these ranch homes.
We carry OEM DuraFlex connectors, top plates, and termination caps in our Beaverton DuraFlex service and Vancouver shop — no waiting on freight to Ohio when your Cedar Hills fireplace is out of commission mid-January. For clay tile systems with more than three cracked sections, we recommend full relining over patching; HeatShield or Gelco buys time but doesn’t stop the systemic moisture drive that rots clay in this climate.

What drives cost: chimney height, accessibility, degree of creosote buildup, and whether the existing clay liner requires extraction or can remain as a sleeve. Every estimate we provide in Cedar Hills includes the full video inspection — no separate charge to “look and see.” We don’t quote relines over the phone without seeing the flue; the Johnson-McDonald undersize issue changes material specs, and we’d rather measure once than eat a return trip. Call (888) 916-8797 for an exact quote — estimates are free, and Larry handles them personally.

FAQs — DuraFlex Chimney Cleaning in Cedar Hills
Yes — in most Cedar Hills homes, we leave the existing clay tiles in place and pull the DuraFlex liner through as a new sleeve. We remove tiles only when they’ve shifted enough to obstruct the flue or when spalled fragments have fallen into the smoke chamber. During your free estimate, we’ll run a camera to determine which approach applies. Call (888) 916-8797 to schedule.
The Johnson-McDonald Company built Cedar Hills’s original homes with flues undersized by roughly 20% relative to the firebox opening. Cleaning removes creosote but doesn’t change the geometry — smoke still stalls in the firebox before the draft can establish. We solve this with DuraFlex ovalization at the top four feet, increasing effective flue area without breaking into the masonry. Same-day evaluation available.
Persistent moisture wicks through aging mortar and pools at the base of chimneys, promoting corrosion at 304 stainless seams and accelerating clay tile spalling. We specify DuraFlex 316L for Cedar Hills specifically for its molybdenum resistance to this chloride-rich wet environment, and we seal crowns with silicone-modified concrete rather than standard mortar.
DuraFlex 316L and High-Temp Aluminized models are listed for gas appliance venting under applicable UL standards. We verify BTU output and vent configuration before specifying — a 40,000 BTU insert in a Cedar Hills ranch requires different sizing than the same unit in a taller chimney. Larry confirms compatibility during the Level 2 Inspection.
The cap style — Gelco, Famco, or generic — doesn’t change the DuraFlex liner spec, but it signals whether previous work addressed the crown properly. A poorly fitted cap traps moisture against the flue collar, accelerating the freeze-thaw damage we see throughout Cedar Hills’s 1950s stock. We inspect the crown condition before finalizing liner diameter; ovalization requires adequate clearance at the top plate. Call (888) 916-8797 and we’ll sort out what’s actually up there.
