Core Capabilities
Flue Diagnostics
Video scan & draft evaluation
Continuous digital camera inspection through all flue tiles, identifying hairline thermal fractures, creosote glaze, and draft obstructions before lighting winter fires.
Soot Containment
Mechanical sweep & glaze removal
Rotary brush sweeping paired with negative-pressure HEPA vacuums removes Stage 3 creosote while maintaining complete particulate isolation inside the residence.
Liner Integrity
Stainless relining & damper repair
Custom titanium-stabilized stainless steel liners, firebox reconstruction, smoke chamber parging, and top-sealing energy dampers that prevent conditioned air loss.
Exterior Masonry
Lime repointing & copper caps
Breathable Type N lime mortar joint restoration for pre-war brickwork, custom stainless chase covers, poured concrete crown repairs, and waterproof sealing.
Surgical Discipline
Our four-stage clearance protocol
Canvas isolation barrier
Full-length camera probe
Rotary mechanical sweep
NFPA written clearance
We lay heavy double-layer drop-cloths across the hearth perimeter and engage commercial negative-pressure HEPA filtration before unboxing tools.
A robotic dual-axis camera travels the entire flue height, recording joint separation, moisture intrusion, and creosote density on digital video.
Specialized poly-core whip systems sweep flue walls clean without chipping historic clay tiles or dislodging soft pre-war brick assemblies.
You receive a signed NFPA 211 condition report with recorded interior video stills and actionable line-item maintenance recommendations.
Safety Benchmarks
Every flue inspection conforms to strict NFPA 211 diagnostic safety standards.
We preserve century-old Northwest DC chimneys with breathable lime mortar and calibrated airflow modeling to ensure zero smoke spillover and total combustion integrity.
