Why Horizon Chimney Sweep Washington Is Maltby’s Preferred Chimney Repair Company
We’ve built our reputation in Snohomish County one chimney at a time. Our 1,006 verified reviews carry a 4.8-star average — not from a handful of jobs, but from nearly two decades of homeowners who called us back year after year. James Wilson arrives as the lead technician on Maltby jobs, not a subcontractor you’ve never met. That matters on acreage properties where diagnosing the real problem often means understanding how the homeowner burns, what wood they’re using, and how the original builder set things up in 1978.
Our response time to Maltby is typically same-day or next-day during the burning season. We stock Gelco caps, Olympia Chimney liner sections, and Famco flashing kits on our trucks — common failure points in Maltby’s wetter foothills climate. We don’t run back to Seattle for parts while your chimney leaks.
Our Chimney Repair Services in Maltby
Mortar Repointing
Maltby’s heavier annual precipitation — more than the Puget Sound lowlands get — keeps chimney crowns and mortar joints saturated for months. We grind out deteriorated mortar to proper depth and repoint with color-matched, high-bond mortar formulated for Pacific Northwest freeze-thaw cycles. On the older farmhouses near the Maltby Cafe, we’ve repointed original 1950s brickwork that had turned to powder behind the face. Done right, repointing adds 20+ years of service life.
Spalling Brick Repair
Spalling — brick faces popping off from moisture penetration — is epidemic in Maltby. The combination of glazed creosote holding moisture against the flue liner, plus persistent foothills rain attacking the exterior, destroys brick from both sides. We remove spalled units, install matching replacement brick, and seal with breathable waterproofing. James Wilson has replaced entire courses on chimneys where spalling had progressed to structural compromise. Caught early, it’s a repair. Ignored, it’s a rebuild.
Chimney Waterproofing
Waterproofing isn’t optional in 98072. We apply vapor-permeable sealers that let the chimney breathe while blocking liquid water — critical on Maltby properties where a single rain event can drop an inch in 24 hours. We pay special attention to the chimney-shoulder interface on older homes, where original flashing has often failed completely. Our waterproofing includes crown resurfacing with flexible, UV-stable compounds that bridge hairline cracks before they become entry points.
Flashing Repair
Maltby’s rural properties often have complex rooflines — additions, detached workshops, metal roofing retrofits — that make proper chimney flashing a specialized job. We fabricate custom flashing from copper and coated steel, integrating with existing roofing without disturbing warranties. On a recent job near Cottage Lake, we replaced rusted step flashing that had been dumping water into a wall cavity for three burning seasons. The homeowner smelled it every time the stove got hot.

Trusted Brands We Service in Maltby
We install and repair with Gelco stainless steel caps, Olympia Chimney relining products, and Famco venting components — brands that hold up to Maltby’s wet winters and heavy burning schedules. These aren’t big-box substitutes; they’re what we specify when a Maltby homeowner needs a repair that outlasts the next storm cycle. We keep common sizes and fittings stocked, so most Maltby jobs don’t wait on shipping.
Common Chimney Repair Problems We See in Maltby Homes
- Glazed creosote bonding to flue liners. Burning green alder or fir from your own lot produces third-degree creosote that mechanical brushing alone won’t remove. We chemical-treat first, then sweep — a two-stage process that’s standard here, rare in Woodinville.
- Deteriorated mortar from persistent moisture. Maltby’s foothills rainfall keeps chimneys wetter longer than Bothell or Kirkland. Mortar joints that look sound in September are crumbling by March. We catch this during annual inspections.
- Failed chimney crowns and shoulder leaks. The concrete crown takes the worst weather exposure. In Maltby, freeze-thaw cycling against saturated concrete causes cracking that channels water straight to the flue. Crown resurfacing or replacement is a frequent fall repair.
- DIY stovepipe runs with improper clearances. On 1970s–1990s rural builds, owner-installed stovepipe often runs too close to combustibles or uses unsupported horizontal sections. We see this on cleaning calls and quote correction before it becomes a house fire.

FAQs — Chimney Repair in Maltby
Maltby homeowners burn self-cleared alder and fir that’s rarely properly seasoned, and our heavier foothills rainfall keeps even stacked wood damp. This combination produces thick, glazed creosote that bonds to flue liners and requires chemical softening before mechanical removal. In Woodinville, more residents buy kiln-dried cordwood, so basic sweeping usually suffices. If you’ve burned two or more cords of your own wood last winter, expect us to recommend chemical pretreatment — call (866) 541-8697 and we’ll assess it during your free estimate.
Mortar repointing and crown resurfacing are the most frequent repairs we perform on Maltby’s 1950s–1980s farmhouses. Decades of Pacific Northwest moisture cycling degrade mortar joints to sand, while concrete crowns crack and allow water to saturate the chimney core. We repoint with color-matched mortar and apply flexible crown compounds that flex with freeze-thaw stress. James Wilson has repointed chimneys on Paradise Lake Road properties that hadn’t seen maintenance since the original construction.
We can replace or reroute DIY stovepipe installations to meet current clearance requirements and proper support spacing. We do not “repair” unsafe configurations in place — we correct them. This typically involves replacing single-wall pipe with proper clearances, adding support brackets, or in some cases rerouting through a wall or roof with insulated chimney pipe. We’ll show you exactly what’s wrong and quote the correction before starting.
Most repairs — repointing, spalling brick replacement, flashing repair — are completed in one day. Jobs requiring scaffolding on two-story farmhouses, or partial rebuilds with extensive brick matching, may extend to two days. We schedule Maltby acreage properties with buffer time for longer driveways and site access, so we’re not rushing or charging you for transit delays. Call (866) 541-8697 to discuss your timeline.
Yes, we repair and inspect chimney systems on detached workshops, barns, and outbuildings throughout Maltby’s rural properties. These installations often use older Class A chimney pipe or improvised stovepipe runs that see heavy use during workshop hours. We inspect for proper clearances, creosote buildup, and structural integrity — the same standards we apply to residential systems.
