Abraham Chimney Inc in San Rafael, CA








Primary Solutions
Zero-Mess Creosote Mitigation
Heavy-duty poly containment runners isolate hearth perimeters before pneumatic rotary brushes clear third-stage creosote deposits without releasing particulate dust into domestic living quarters.
NFPA 211 Camera Diagnostics
Dual-axis robotic cameras descend the entire vertical flue run, documenting baseline clay tile spalling, missing mortar joints, and concealed thermal fractures directly with the property owner.
Historic Lime-Mortar Tuckpointing
Raked exterior mortar joints undergo systematic repointing with custom-blended hydraulic lime mortars calibrated to match historical brick expansion rates and resist salt-fog degradation.
Coastal Spark Arrestor Fabrication
Marine-grade 304 stainless steel and copper spark arrestors engineered to stop wind-driven ember intrusion while withstanding intense coastal salt air without premature galvanic rot.
Flue Engineering
Specialized Hearth Restorations
Beyond seasonal sweeping, our certified technicians resolve critical airflow deficiencies, drafting failures, and thermal containment issues.
Top-Sealing Lock-Top Dampers
Smoke Chamber Parging
Poured Concrete Crown Rebuilds
Spring-loaded stainless assemblies seat tightly across the flue crown, eliminating conditioned air loss and stopping cold downdrafts.
Application of refractory insulating mortar transforms corrugated corbelled brick steps into smooth transitional draft throats that accelerate smoke evacuation.
Reinforced overhanging mortar crowns with integrated drip edges cast off rainwater to shield porous exterior brickwork from freeze-thaw cracking.
Field Standards
Structured Four-Stage Execution
Surface Isolation
Mechanical Sweep
Internal Video Scan
Owner Documentation
Canvas drop runners and HEPA extraction barriers isolate the fireplace envelope before diagnostic equipment enters the residence.
Rotary whips and specialty brass brushes dislodge combustible glazed soot from firebox, smoke shelf, and vertical chimney liner.
Calibrated optical cameras inspect every linear foot of chimney flue to verify liner integrity and structural clearances.
Clients receive an immediate annotated condition report outlining clearance findings, NFPA compliance, and prioritized repair requirements.
Direct dispatch across San Rafael, Mill Valley, Novato, and surrounding North Bay communities. Technicians arrive equipped for same-day diagnostics.
