DuraFlex Chimney Cleaning in Cedar Hills, WA | Horizon Chimney Sweep Washington
DuraFlex chimney cleaning and inspection in Cedar Hills typically runs $180–$340 for a standard sweep with Level 2 camera inspection, and most appointments are completed same-day. What sets our DuraFlex services apart in Cedar Hills is the age of the housing stock: most 97005 chimneys were built with 8×8 clay tile flues in the 1950s–70s, and we’ve spent 17 years learning how DuraFlex retrofits behave in those exact conditions. If you’re smelling smoke, seeing rust on your cap, or you’ve just bought a mid-century ranch with an unknown liner history, call us at (866) 541-8697 for a free estimate.
Why Cedar Hills Residents Choose Us for DuraFlex Service
James Wilson grew up in the Tenleytown neighborhood and has spent his entire adult life working in the trades here. He picked up the fundamentals at Northern Virginia Community College before apprenticing under a sweep who showed him what textbooks never cover — what a chimney actually looks like after fifteen winters of neglect. That apprenticeship still shapes how we approach every Cedar Hills job.
We’re not a manufacturer-authorized DuraFlex dealer. We’re an independent service provider with 1,006 verified reviews averaging 4.8 stars, and we think that’s the better arrangement for homeowners. It means when we inspect your DuraFlex liner, our recommendation isn’t influenced by a brand quota or warranty program. If your DuraFlex Plus 316Ti has seam fatigue from two decades of Cedar Hills freeze-thaw cycling, we’ll tell you straight whether a section replacement or full reline makes sense. James still serves as lead technician on most jobs, so the person quoting your work is the same one who’ll be on your roof.
We stock genuine DuraFlex sections for system-matched repairs, but we also carry heavy-gauge stainless aftermarket caps and top plates that outlast galvanized hardware by years in this damp foothill climate. Our truck carries DuraFlex 2100 Series, Plus 316Ti, AL13, and S Type components — enough to handle most Cedar Hills same-day repairs without a parts order.
Common DuraFlex Chimney Cleaning Problems We Solve in Cedar Hills
- Seam separation on DuraFlex 2100 Series liners. The 20–30 overnight freezes each Cedar Hills winter don’t sound dramatic, but they’re enough to crack moisture-laden clay tile liners through thermal expansion. Once that clay spalls, fragments lodge in DuraFlex 2100 seam joints, prying them open during freeze cycles. We catch this with camera inspection — not guesswork.
- Crimp-joint failure at prefabricated elbows on pre-2010 DuraFlex Plus installs. Cedar Hills sits lower than the Tualatin Mountains crest, and that autumn fog lingers here longer than in flat Portland. Persistent moisture wicks into crimp joints that weren’t sealed with modern compounds, corroding the 316Ti from the inside out. We’ve replaced elbows on homes near the Cedar Hills Recreation Center where the joint looked fine from the top but was paper-thin at the bend.
- Spalled clay tile behind retrofitted DuraFlex inserts. This is the Cedar Hills special. Gas inserts dropped into 1960s fireplaces without proper liners leave old mortar fragments blocking drainage channels. Water pools, the clay tile spalls behind the flex metal, and the DuraFlex corrodes from below where you can’t see it. Our Level 2 inspection finds this before your carbon monoxide detector does.
- Corroded top plates and caps from galvanized hardware. The roughly 45 inches of annual precipitation in Cedar Hills — heavier than Portland’s core — destroys galvanized chimney components in four to six years. We see rusted DuraFlex caps that should have been stainless from the start. Our replacements use aftermarket heavy-gauge stainless that handles the wet season without drama.
- Custom reducer gaps trapping debris. Cedar Hills’s 1950s–60s ranch homes were built with 8×8 clay tile flues. Standard 6-inch DuraFlex liners leave a 2-inch annular gap that collects fallen mortar, bird nests, and condensation. Without a custom tapered reducer, that gap becomes a moisture trap that accelerates liner corrosion. We fabricate and install these on-site.
DuraFlex Service in Cedar Hills: What Local Conditions Mean for Your Equipment
Cedar Hills is a mid-century suburban build-out — the bulk of the 97005 housing stock dates from the 1950s through 1970s, meaning the area’s masonry chimneys and original clay-tile flue liners are now 50–70 years old and have been subjected to decades of Pacific Northwest moisture cycling. That specific combination of aging single-wythe brick construction and the relentless wet-season rainfall unique to this foothill-adjacent microclimate makes structural deterioration — not just creosote buildup — the dominant chimney issue Cedar Hills technicians face, setting it apart from newer suburban rings like Beaverton DuraFlex service areas or Tigard.
For DuraFlex owners, this reality changes everything. A liner installed in a 1965 ranch on Southwest Lloyd Street isn’t performing in the same environment as DuraFlex in West Haven-Sylvan or a 2005 Hillsboro build. The single-wythe brick in Cedar Hills has absorbed six decades of rain, freeze, and thaw. Mortar joints are porous. Crowns are cracked. Water finds its way behind DuraFlex liners and sits there, especially when the original 8×8 clay flue creates that annular gap we keep mentioning. We’ve learned to inspect for water staining on the flex metal itself — a telltale sign that the liner is essentially operating inside a damp sleeve. In newer construction with proper damp-proofing and double-wythe chimneys, DuraFlex liners dry out between storms. In Cedar Hills, they often don’t. That’s why we push harder for full replacement over patching here. A seam repair in a dry climate might last ten years. In a 97005 chimney with compromised masonry, we’ve seen moisture re-open repairs within eighteen months. The local conditions don’t forgive shortcuts.
DuraFlex Models & Products We Service in Cedar Hills
We work on the full DuraFlex residential line: the 2100 Series (the original corrugated stainless flex, common in 1990s–2000s relines), DuraFlex Plus 316Ti (the heavier-wall upgrade many Cedar Hills homeowners chose for wood-burning conversions), DuraFlex AL13 (aluminum alloy, lighter duty, usually found with gas appliances), and DuraFlex S Type (the 304 stainless option for specific venting configurations).
Our truck stocks 6-inch and 8-inch diameters in 316Ti and 2100 Series, plus custom tapered reducers for those 8×8 Cedar Hills clay flues. For caps, top plates, and storm collars, we default to heavy-gauge stainless aftermarket parts that outlast galvanized DuraFlex OEM hardware in this environment. When a structural repair demands genuine DuraFlex sections for warranty or code compliance, we source them — but we’ll always explain why and show you the compatibility issue. No parts markup mysteries.

FAQs — DuraFlex Chimney Cleaning in Cedar Hills
Yes, but you’ll need a custom tapered reducer. Standard 6-inch DuraFlex leaves a 2-inch gap that traps moisture and debris against your aging clay tile. We fabricate 8-to-6 reducers on-site for Cedar Hills’s common ranch and split-level stock. Call (866) 541-8697 and we’ll measure your flue during the free estimate.
Annually, without exception. The persistent October-to-May rainfall here saturates masonry that DuraFlex liners depend on for support. We find new spalling, crown cracks, and cap corrosion every year in Cedar Hills — not every two years, every year. Call (866) 541-8697 to get on the calendar before the heavy rains return.
Your cap is probably galvanized, not stainless. Cedar Hills’s 45+ inches of annual precipitation destroys galvanized hardware in four to six years — we’ve documented this repeatedly near the recreation center and along Southwest Beaverton-Hillsdale Highway corridors. We replace with heavy-gauge stainless aftermarket caps that handle the damp. Call (866) 541-8697 for a cap swap quote.
Probably. Pre-2000 DuraFlex 2100 Series in Cedar Hills has usually endured twenty-plus years of moisture cycling in single-wythe chimneys. We recently serviced a 1962 split-level on Southwest Lloyd Street where a gas log insert had been dropped into the original clay flue without any liner. Our Level 2 camera inspection revealed the clay tiles were spalled at the second offset, leaking carbon monoxide into the attic space. We installed a 316Ti DuraFlex liner with a custom 8-to-6 reducer, then sealed the crown with a flexible coating — all in one morning, saving the homeowner from an unpermitted configuration they’d inherited when they bought the house, similar to DuraFlex repair in Raleigh Hills cases we’ve handled. If your liner is original to a 1990s reline, schedule a camera inspection. Call (866) 541-8697.
Disclose it to your insurer first, then call us for a Level 2 inspection. Washington County tightened enforcement after many of these 1980s–2000s retrofits, but the existing installs weren’t grandfathered. We document the configuration, test draft and spillage, and quote correction to code — usually a properly sized DuraFlex liner with permit-ready documentation. We’ve handled this exact scenario dozens of times in 97005. Call (866) 541-8697 to get compliant.
