Chimney Cleaning for Wood-Burning Stove Inserts

Wood-burning stove inserts (also known as heat recovery fireplaces) are an excellent way to heat a home more efficiently. However, compared to open fireplaces, these systems generate higher combustion temperatures, which can lead to faster buildup of soot and creosote inside the flue. That’s why regular chimney cleaning is essential to ensure safe and optimal operation.

At Servilar, we offer professional chimney cleaning for heat recovery stoves and fireplace inserts across the Greater Lisbon area. Whether installed in houses, apartments, or seasonal homes, our team tailors the cleaning to the technical needs of each system.

Why do stove inserts need more frequent maintenance?

Greater soot and creosote buildup: The high-intensity combustion causes particles to stick to the flue walls.
Narrower or curved ducts: Common in stove systems, they require special tools and skilled handling to clean thoroughly.
Reduced efficiency: Blocked flues can lower the stove’s performance and cause smoke to enter the room.
Fire risk: Creosote is highly flammable and must be removed periodically to prevent chimney fires.

Full-service cleaning with inspection and expert advice

Servilar’s technicians use rotary mechanical brushes, industrial vacuums, and video inspection when needed. After cleaning, we assess the condition of the flue and system, and provide guidance on any further maintenance, such as seal replacement or duct repair.

When should you clean your stove insert?

We recommend cleaning:

Once per year, ideally before winter starts
After long periods of inactivity
Whenever you smell smoke or notice poor draft
