Our Fireplace Services team knows these hills.

Why Horizon Chimney Sweep Washington Is West Slope’s Preferred Fireplace Services Company
We’ve built our reputation one chimney at a time — 1,006 verified reviews averaging 4.8 stars, with James Wilson, our owner, still climbing roofs as lead technician. That’s not marketing language; it’s why a homeowner off SW 78th Avenue called us back last season after we diagnosed a draft issue their previous sweep missed entirely.
West Slope sits in unincorporated Washington County, which means no city permit office to navigate — just the county’s land use and building division. We’ve routed enough paperwork through Hillsboro to know the inspection pathways cold. When you’re staring at a cold fireplace in November and need a liner replacement approved fast, that familiarity saves weeks.
Our response time to West Slope averages two business days for standard appointments, same-day for urgent downdraft or smoke-spillage calls. The sloped lots off SW Ridge Drive and SW Patton Road make ladder staging tricky — irregular roof pitches, offset chimney heights, sometimes narrow driveway access — but we’ve done this enough to arrive with the right equipment rather than improvising on your roof.
Those 1,000-plus reviews reflect repeated trust, not a lucky streak. Homeowners in West Slope call us back because we name the problem specifically — “windward mortar joint erosion at the third course,” not “your chimney needs work” — and we fix it with materials built to last: DuraFlex liners, HeatShield crown sealant, Copperfield dampers when the original cast-iron frame has warped beyond adjustment.
Our Fireplace Services in West Slope
Gas Fireplace Service
Gas fireplaces in West Slope’s 1950s–1970s ranches often sit in original fireboxes never designed for them — converted from wood-burning with venting that doesn’t account for the hillside downdraft pressure we see here. We inspect gas valve assemblies, pilot orifices, and thermocouple positioning, but we also check whether your vent termination is fighting Pacific winds head-on. A misaligned vent cap on a windward slope can extinguish pilots repeatedly or cause rollout. Service runs $180–$320 for standard cleaning and safety inspection; valve or burner replacement adds $150–$400 depending on parts.
Wood Burning Fireplace
Original single-wythe masonry fireplaces dominate West Slope’s housing stock, most with clay-tile flue liners now 50–70 years old. The persistent moisture off the Tualatin Mountains keeps these liners damp October through April, and when a cold snap hits, freeze-thaw cycles exploit every hairline crack. We sweep, camera-inspect, and document liner condition — but we’re also looking at the windward face for spalling brick and eroded mortar joints that let water behind the wythe. A level II inspection with sweep runs $280–$380; firebox repointing starts around $450.
Fireplace Insert
This is where we solve West Slope’s chronic downdraft problem at the source. A properly sized insert with a continuous stainless steel liner — we use DuraFlex for the flex sections, Olympia Chimney rigid pipe where straight runs allow — creates a controlled combustion chamber and positive draft independent of the original flue’s deteriorated condition. For homes off SW 80th Avenue where wind howls down the original throat damper all winter, an insert transforms a useless, smoking fireplace into the primary heat source. Insert installation in West Slope ranges $2,800–$4,500 depending on unit size, liner length, and whether we need to reframe the surround for a proper seal.
Damper Repair
Original throat dampers in West Slope’s mid-century homes are cast iron, often rusted solid or warped from decades of uneven heating. Worse, a failed damper in a hillside home means Pacific wind has an open pathway into your living room year-round. We repair when possible — new damper plates, pivot pin replacement — but often recommend a top-sealing damper from Copperfield or Famco installed at the flue termination. It seals against weather, stops downdraft, and operates by cable from the firebox. Repair: $220–$340. Top-sealing damper installation: $380–$520.
Firebox Repair
The firebox takes direct thermal cycling, and in West Slope’s aging masonry, we’ve found refractory panels cracked from thermal shock, hearth extensions settled on hillside-compromised foundations, and rear walls where mortar has turned to sand. We repoint with high-temperature refractory mortar, replace damaged brick, and install steel firebox liners when the original structure can’t be restored safely. Firebox repair in West Slope runs $650–$1,800 depending on whether we’re addressing surface repointing or rebuilding the rear wall and throat.
Fireplace Conversion
Converting a wood-burning fireplace to gas in West Slope requires Washington County permit routing and inspection — not Portland’s system, not Beaverton’s. We handle the paperwork, run proper gas lines to code, and install vented log sets or direct-vent inserts with termination caps positioned to minimize wind interference. Conversion projects start around $1,800 for basic log sets, $3,200–$5,500 for direct-vent inserts with full liner systems.
Trusted Brands We Service in West Slope
We don’t do off-brand patchwork. For West Slope’s wind-battered chimneys, we specify DuraFlex stainless steel liners for their corrosion resistance against constant moisture exposure, and HeatShield cerfractory sealant for crown repairs that need to flex through freeze-thaw without cracking. Copperfield dampers and Famco termination caps round out our typical material list for this market. We stock common sizes and configurations to avoid the two-week order delays that leave you with a cold fireplace through another storm cycle. When we quote a job, we’re quoting materials we trust to outlast the next decade of Pacific wind.
Common Fireplace Services Problems We See in West Slope Homes
- Windward mortar joint erosion. On a recent job off SW Ridge Drive, we found a 1960s single-wythe chimney where prevailing winds had eaten away windward mortar joints to half their original depth. We relined with a DuraFlex stainless steel liner and sealed the crown with HeatShield, stopping the years-long downdraft issue that had plagued the homeowners every winter.
- Chronic downdraft and smoke spillage. West Slope’s hillside exposure interrupts proper draft in ways flat-valley chimneys rarely experience. We see smoke rolling into living rooms on otherwise calm days because the pressure differential across the slope overcomes the chimney’s natural draw.
- Freeze-thaw damage to saturated masonry. West Slope receives slightly higher annual rainfall than Portland’s east side due to orographic lift, keeping chimneys damp for months. When winter cold snaps hit, water in cracked clay-tile liners and mortar joints freezes, expands, and opens new pathways for the next cycle.
- Failed original dampers wasting energy. A rusted-open throat damper in a 1960s ranch off SW Patton Road means heated air escapes constantly and wind pours in. We’ve measured temperature drops of 8–10 degrees near the hearth in homes with this single failure.

FAQs — Fireplace Services in West Slope
West Slope sits on the western-facing slopes of the Tualatin Mountains, where prevailing Pacific winds strike chimneys directly rather than being blocked by the West Hills that shelter Portland’s east side. This constant moisture-laden wind accelerates mortar joint erosion on windward faces and creates pressure differentials that cause chronic downdrafting — problems rare in the sheltered valleys below. If you’re seeing white efflorescence on your brick or smelling smoke in the room on windy days, this hillside exposure is likely the culprit. Call (866) 541-8697 and we’ll diagnose the specific wind path affecting your chimney.
Because West Slope is unincorporated Washington County rather than an incorporated city, chimney relining, insert installation, and conversion permits route through the county’s land use and building division in Hillsboro — not through Portland or Beaverton municipal offices. The inspection pathways and fee schedules differ, and turnaround times vary seasonally. We’ve filed enough of these to know the current timeline and inspector expectations, which keeps projects moving rather than stalling in jurisdictional confusion. For current permit costs and scheduling, call us at (866) 541-8697.
The 97225 ZIP is dominated by homes built during Washington County’s postwar suburban expansion, most with original clay-tile flue liners now 50–70 years old. We regularly find vertical cracking from thermal shock, joint separation allowing creosote leakage into wall cavities, and spalling tile fragments obstructing the flue — all exacerbated by West Slope’s persistent dampness and freeze-thaw cycling. A camera inspection reveals what a basic sweep cannot; we include this in our Level II inspection. Schedule yours at (866) 541-8697 — estimates are free.
Yes — a properly installed fireplace insert with a continuous stainless steel liner is one of the most effective solutions for West Slope’s chronic downdraft issues. The insert’s sealed combustion chamber and controlled air intake create positive draft independent of the original flue’s deteriorated condition, while the liner eliminates the leakage points where wind pressure disrupts draw. We’ve installed inserts in homes off SW Ridge Drive and SW 80th Avenue where homeowners had abandoned their fireplaces entirely due to smoke spillage. For insert sizing and pricing specific to your chimney, call (866) 541-8697.
Not always, but we assess for it on every job — especially on hillside homes where foundation settling or wind-driven mortar erosion has compromised structural integrity. If the wythe has separated from the house frame or the windward face shows significant spalling, we may recommend external bracing, crown reconstruction, or partial rebuild before or concurrent with liner installation. We never install a liner in a chimney that won’t safely contain it. For a structural assessment with your liner quote, call (866) 541-8697.
