Donovan Chimney Co

Chimney cleaning plays an important role in maintaining a safe fireplace. Regular sweeping helps improve airflow and ventilation. It can also reduce the risk of chimney fires caused by creosote buildup. Proper maintenance helps identify potential issues before they become serious. Clean chimneys allow smoke to escape more effectively. Routine care also supports the long-term performance of fireplace systems.

Precision sweeping and camera inspection

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.
