Dennis Chimney Sweep Crew
Hearth Perimeter Containment
Internal Video Diagnostics
Rooftop Structural Assessment
Before any sweep begins, we lay industrial drop tarps and secure dual-motor HEPA vacuum seals across your firebox to capture all airborne particulates.
Our technicians run high-resolution articulating cameras up the flue column to record hidden clay liner cracks, mortar decay, and stage-three glazed creosote deposits.
We inspect exterior brick masonry, chimney crowns, counter-flashing seams, and spark arrestor screens for freeze-thaw spalling, rust, and alpine wildlife intrusion.








Technical Chimney Services
Creosote Mitigation Sweep
High-torque rotary brush systems strip flammable glazed creosote from clay flues and stainless steel liners, restoring optimal chimney drafting without scratching interior tile walls.
Spark Arrestor Installation
Heavy-gauge stainless steel mesh caps prevent burning embers from drifting into the pine canopy while keeping heavy mountain snow, rain, and nesting wildlife out of your flue.
Crown Sealing & Mortar Tuckpointing
Sub-zero mountain freeze cycles crack traditional mortar beds. We apply elastomeric waterproof crown coatings and perform structural tuckpointing to prevent costly moisture penetration.
Throat Damper Replacement
Cast-iron throat damper replacements and top-sealing energy dampers stop cold downdrafts from cooling your cabin living room when the firebox sits idle during winter nights.
Zero Soot Inside, Maximum Fire Defense Outside
Every service call conforms to NFPA 211 mountain heating codes, combining industrial negative-pressure containment with documented flue clearance checks before your first winter fire.
Direct dispatch across Running Springs and high-elevation cabin communities six days a week.
