Why Hearthstone Chimney Co. Is West Slope’s Preferred Chimney Repair Company
We’ve been serving West Slope for over 42 years, long enough to have worked on the same chimney twice as ownership changed hands. Our technicians are background-checked, uniformed, and trained to document every inspection with Level-2 camera footage you can see yourself, plus a plain-English verdict on what needs fixing now versus what can wait.
Response time matters here. West Slope’s hillside lots and limited through-streets mean a crew unfamiliar with the area wastes twenty minutes navigating dead-end courts and unmarked driveways. We don’t. Most West Slope calls are scheduled within 48 hours, and emergency situations - a leaking flue, a damaged crown letting water straight into the firebox - get same-day response when safety is at stake. For routine maintenance, we also offer Chimney Cleaning & Sweep - West Slope services.
Our 90-Day Done Right Promise applies to every West Slope job in writing. If it’s not right, we come back. No paperwork to dig up, no arguing. That’s the Keystone Standard we’ve operated under since Russell Haines founded this company, and it’s why West Slope homeowners who’ve been burned by contractors before tend to stick with us once they’ve tried us.
Our Chimney Repair Services in West Slope
Mortar Repointing
The 1950s-1970s brick fireplaces common throughout West Slope are now pushing 50-70 years on their original mortar joints. Pacific storm moisture channels directly into this hillside community, and the freeze-thaw cycles at elevation chew through soft lime mortar faster than you’d see in the Tualatin Valley below. Tuckpointing and full repointing are our most frequent West Slope requests. We grind out deteriorated joints to proper depth and repack with color-matched, professional-grade mortar - not the quick-setting bag mixes that fail in two seasons. A typical mortar repointing job in West Slope runs $450-$1,200 depending on accessible surface area.

Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is epidemic in West Slope’s mid-century chimneys. The sustained dampness here saturates porous brick through our long wet season, then winter freezes expand the trapped water and pop the face right off. Upper-slope properties near the ridgeline see this worst. We assess whether individual bricks can be replaced or if the damage indicates deeper structural compromise requiring Chimney Liner & Rebuild - West Slope work. Spalling brick repair in West Slope typically ranges from $280 for localized replacement to $1,800 for extensive face restoration with waterproofing.

Chimney Waterproofing
Water is the enemy of every West Slope chimney, and standard masonry sealers from the hardware store trap moisture inward rather than repelling it. We apply vapor-permeable treatments formulated for Pacific Northwest conditions - products from HeatShield and Famco that let the chimney breathe while shedding rain. For chimneys already showing water damage, we often pair waterproofing with crown resurfacing using Gelco materials. Waterproofing a West Slope chimney runs $350-$650 for application, more if crown repair or flashing work is needed simultaneously.

Flashing Repair
The steep roof pitches and irregular chimney placements on West Slope’s hillside lots make flashing details more complex than flat-land installations. Step flashing corrodes, counterflashing separates, and the resulting leaks often masquerade as roof problems until a chimney-specific inspection reveals the true source. We fabricate and install custom flashing with proper overlap and sealant compatibility for your roofing material. Flashing repair in West Slope generally costs $320-$780; full replacement at complicated roof-to-chimney intersections can reach $1,100.
We also handle Chimney Cap & Crown in West Slope when the damage extends above the roofline, and our Fireplace Services in West Slope cover the firebox, damper, and hearth components that complete your system.

Trusted Brands We Service in West Slope
We don’t use builder-grade substitutes. For West Slope repairs, we stock and install professional-grade materials from Olympia Chimney, HeatShield, and Famco - brands that hold up to the sustained moisture and freeze-thaw stress this hillside climate delivers. Having the right parts on the truck means most West Slope jobs finish in one visit, not two. When a clay tile liner needs HeatShield resurfacing or a custom Famco cap is required for an odd-angle chimney termination, we don’t leave you waiting on a parts order from out of state.
Common Chimney Repair Problems We See in West Slope Homes
- Glazed creosote accelerating mortar decay. West Slope homeowners burn Douglas fir - a resinous softwood that deposits creosote at roughly twice the rate Eastern hardwood guidelines assume. That glazed buildup traps acidic moisture against firebox walls and smoke chamber mortar, eroding joints from the inside even as external weather attacks from outside.
- Cracked clay tile liners dislodged during sweeping. The 50-70-year-old clay flue tiles in West Slope’s original construction are brittle and segmented. Standard rotary sweeping can crack already-compromised sections or knock loose the mortar between them, which is why we recommend Level-2 camera inspection before any cleaning on these aging systems.
- Crown deterioration from freeze-thaw at elevation. West Slope’s position on the Tualatin Mountains’ western face means more freeze-thaw cycles than the valley floor below. Concrete crowns without proper overhang and drip edge crack, allowing water straight down the flue. We see this most on upper-slope homes above SW Oleson Road.
- Flash rust on dampers and hardware. Months of near-continuous moisture during West Slope’s wet season rusts throat dampers, top-sealing dampers, and firegrate hardware. The damper won’t open fully, won’t seal when closed, or drops rust flakes into the firebox - all signs that water intrusion needs addressing, not just the symptom.
