Abraham Chimney Inc in San Rafael, CA

Complete structural flue diagnostics, mechanical creosote mitigation, and historic masonry rehabilitation engineered specifically for Marin County microclimates and seismic standards.

Primary Solutions

Four Essential Flue Protections

Rotary Sweeping

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.

Internal Optics

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.

Masonry Restoration

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.

Roof Protection

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.

Thermal Sealing
Draft Correction
Structural Cap

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.

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.
