Chimney Cleaning in Historic and Older Buildings

Chimney Cleaning in Historic and Older Buildings

In many historic areas of Lisbon, older buildings still have traditional chimney systems, often interconnected through shared flue columns that serve multiple apartments. Over time, these systems can accumulate soot, debris, moisture, and even collapsed internal structures, making chimney cleaning and inspection not just a matter of functionality — but of fire safety and indoor air quality.

At Servilar, we offer specialized chimney cleaning for older buildings and historic properties, with experience in century-old constructions, complex flue systems, and areas where both unblocking and careful inspection are essential.

Common issues in chimneys of older buildings

• Obstructed shared flue columns

• Decades of soot and combustion residue buildup

• Bird nests, leaves, and debris blown into the ducts

• Internal moisture and material deterioration

• Signs of malfunction: smoke returning into the apartments, persistent odors, difficulty lighting fireplaces

How we intervene

• Initial assessment of the chimney system (individual or shared)

• Use of rotary mechanical brushes and industrial vacuum equipment

• Video inspection, when needed, to verify internal conditions

• Technical advice on flue repairs, pipe replacement, or adding access panels

• Cleaning reports for building managers or condominium associations (upon request)

We work with:

• Historic residential buildings in central Lisbon

• Apartment buildings with fireplaces or stove inserts

• Flats where chimneys have been inactive for years

• Urban rehabilitation projects
