Donovan Chimney Co






Level II video flue inspection
High-definition camera passage through your flue interior identifies hairline clay tile fractures, hidden obstructions, and draft turbulence for real estate transfers and annual safety.
Stage 3 creosote removal
Mechanical rotary whip rods and specialized chemical neutralization dissolve dangerous glazed creosote deposits that standard wire brushes cannot displace, eliminating high-heat chimney fire fuel.
Draft troubleshooting and smoke abatement
Detailed differential pressure testing pinpoints negative air stack effects, cold flue downdrafts, and smoke back-puffing into your living area caused by improper throat geometry.
Masonry preservation and hardware replacement
Structural brick repair, moisture barrier defense, and stainless steel venting upgrades built to endure foothill wind patterns.
Crown rebuilds and chimney caps
Historic brick tuckpointing
Stainless steel flue relining
Poured concrete crown restoration and spark arrestor chimney caps prevent rainwater penetration, avian intrusion, and foothill ember risks.
Careful removal of decayed mortar followed by lime-matched repointing stabilizes vintage Arroyo stone and period brick chimneys against seismic wear.
Custom-fitted UL-listed stainless steel liners bypass deteriorated clay tiles, restoring safe draft velocity and modern heat tolerance to older chimneys.
The zero-soot service workflow
HEPA containment setup
Rotary cleaning & inspection
Certified digital reporting
We lay multi-layer drop cloths and seal the hearth opening with negative-pressure industrial HEPA filtration before any sweeping equipment enters your flue.
Technicians deploy motorized rotary rods from hearth to roofline, recording high-resolution video footage of every clay joint and damper surface.
You receive a signed NFPA diagnostic condition report complete with interior flue photographs, clearance measurements, and written maintenance records.
Seven-day dispatch across Altadena, Pasadena, and the San Gabriel foothills. Fast scheduling for home sales, routine cleanings, and masonry repairs.
