Stage 3 Creosote Removal
Glazed tar and chemical creosote require specialized rotary head whips and chemical treatments to eliminate severe chimney fire hazards without fracturing flue tiles.
Camera Flue Scans
Motorized 360-degree cameras travel the entire vertical chimney shaft to document interior joint separation, hairline cracks, and hazardous hidden drafting obstructions.
Masonry Tuckpointing
Decaying mortar joints allow smoke leakage and structural collapse; we rake out defective joints and repack them with high-temperature refractory mortar blends.
Spark Arrestor Fabrication
Custom stainless steel and copper mesh housings prevent airborne ember spread across dry foothill brush while locking out bats, raccoons, and rain intrusion.
Hearth Structural Repairs
Specialized structural repairs designed to prevent moisture penetration, smoke spillage, and hazardous heat transfer into living room framing and historic subfloors.
Smoke Chamber Parging
Crown Sealant Rebuilding
Firebox Refractory Repointing
Rough corbelled brickwork creates turbulent eddies and smoke rollback; smooth refractory parge coating accelerates drafting velocity and limits thermal transfer into wood studs.
Cracked mortar slabs atop chimneys channel rainwater down inner walls; elastomeric crown coats and poured concrete crowns preserve external masonry assemblies.
Degraded firebrick panels and cracked refractory mortar joints are dismantled and reconstructed using structural high-heat hydraulic cements rated past two thousand degrees.
