Unblocking Shared Chimney Flue Columns

Unblocking Shared Chimney Flue Columns

Shared flue columns are vertical chimney ducts that serve multiple apartments in the same building, typically used to evacuate smoke from fireplaces, stoves, or heating systems. In older buildings or those with irregular maintenance, these columns can become partially or fully blocked, putting both comfort and resident safety at risk.

Servilar offers specialized services for unblocking shared chimney flue columns, using professional tools and experienced technicians trained to handle complex and limited-access situations.

Signs of a blocked shared flue

• Smoke entering the apartment instead of exiting

• Persistent odors even when the fireplace is off

• Difficulty lighting the fire or poor draft

• Soot accumulating around the fireplace opening

• Multiple residents reporting similar issues

How we perform the unblocking

• Initial inspection of the flue (video inspection when needed)

• Use of mechanical rotary brushes and high-powered vacuum systems

• Roof, terrace, or technical ceiling access, depending on the situation

• Removal of obstructions caused by compacted soot, nests, debris, or internal collapses

• Optional installation of access panels for future maintenance

Ideal for:

• Apartment buildings with shared flue systems

• Older properties with outdated chimney infrastructure

• Condominiums with recurring smoke complaints

• Buildings undergoing rehabilitation or preparing for sale/rental
