A chimney should be swept once a year, before the first fire of the season. Handyman Algarve arranges chimney sweeping for open fireplaces, wood burners and cooking flues: describe what you have, get a free quote, and the flue is cleaned and checked before you light it.
Chimney sweeping removes the soot and creosote that build up in a flue and checks it is clear before the fire is lit again. In the Algarve the right time is autumn, before the first cold nights, because a chimney that sat unused through a hot summer is the one most likely to hold a bird nest. Handyman Algarve quotes chimney sweeping in the Algarve for free, in English or Portuguese, with the price known before any work starts.
Why do Algarve chimneys need sweeping at all?
The heating season here is short, so it is easy to assume a fireplace barely used needs no attention. The opposite is true, for three local reasons.
Short, hot fires. A few evenings of hard burning through December and January lay down soot quickly, especially with the resinous pine and eucalyptus sold locally.
Nine months of nothing. The flue then stands unused through spring and summer, which is exactly when birds nest in it and when damp air turns loose soot into a hard, tarry layer.
Old, wide flues. Traditional Algarve chimneys are often large, unlined and shared with a cooking hearth, so they draw unevenly and collect more deposit than a modern liner would.
Blackened opening and smoke coming back into the room
Stop using the fireplace until it has been checked. Smoke entering the room means the flue is not clearing properly.
Look up the flue with a torch from the hearth: a solid dark mass rather than daylight usually means a nest or a heavy deposit.
Clear the hearth and move rugs and furniture back before the sweep arrives, so the room is protected.
Ask for the flue to be checked as well as brushed, so cracks and missing mortar are found while the chimney is open.
What does a chimney sweep actually do?
A proper visit is more than a brush up the flue:
Sheeting and sealing the opening so soot goes into the vacuum and not onto your furniture.
Mechanical sweeping with rods sized to the flue, from the hearth, from the roof, or both where the chimney bends.
Removing what is in there, which in the Algarve is often a nest, fallen mortar, or a hardened layer on the first metre above the fire.
Checking the flue and the pot for cracks, missing mortar, and a cowl that has rusted or blown off in a winter storm.
Leaving the hearth clean and telling you plainly what condition the chimney is in.
When is the best time to book?
Autumn, before the first cold snap. Everyone in the Algarve reaches for the fireplace on the same first cold weekend, and that is when sweeps are hardest to get and when chimney fires happen. Booking in September or October means the flue is clear and any repair to the pot or the cowl is found while the weather is still dry enough to do it.
What determines the price?
Chimney sweeping is quoted per chimney, and as of 2026 the things that move the price are concrete: how many flues the house has, whether the chimney is reached from the hearth or from the roof, the height and pitch of that roof, how many seasons of soot are in there, and whether a bird nest or hardened creosote has to be cut out rather than brushed. A cooking flue that needs degreasing is a different job from a fireplace and is quoted separately. The quote is free, given before anyone comes out, and the price you accept is the price you pay.
If the sweep finds a cracked flue, a failed pot or a missing cowl, you get the repair quoted separately and decide then. Nothing beyond the sweep happens without your say so. See how it works for the process from request to finished job.

Frequently asked questions
How often should a chimney be swept in the Algarve?
Once a year for a fireplace or wood burner used through the winter, and before the first fire of the season rather than after it. Algarve homes burn for a short intense season, so soot builds up quickly and then sits in a damp flue for months. A chimney used only two or three times a year still needs checking for bird nests before it is lit.
How much does chimney sweeping cost?
It is quoted per chimney, and the price depends on how many flues the house has, the height and pitch of the roof, how the chimney is reached, how long it has been since the last sweep, and whether a bird nest or hardened creosote has to be removed. Handyman Algarve quotes chimney sweeping free, before anyone comes out, so the cost is known up front.
Do chimney sweeping logs actually work?
Not as a replacement for sweeping. A chemical log can dry out and loosen light soot, which makes a later sweep easier, but it does not remove hardened creosote, it does not clear a bird nest, and it cannot tell you whether the flue is cracked. Use one between sweeps if you like, not instead of one.
What are the signs a chimney needs sweeping?
Smoke coming back into the room, a fire that is hard to light or burns lazily, a strong smell from the fireplace on humid days, soot falling onto the hearth, and dark tarry marks around the opening. Birds heard in the flue in spring and summer mean a nest, which blocks the chimney completely and must be removed before lighting.
Who is responsible for sweeping the chimney in a rented house?
It is normally set out in the tenancy agreement, so check there first. In practice the person using the fireplace is the one who benefits from a swept flue, while the owner is the one whose building is at risk, and many contracts split it that way. Whoever pays, keep the receipt: it is the only proof the chimney was maintained.
Is a kitchen extraction chimney the same job?
No. A cooking flue collects grease rather than soot, and grease is both harder to remove and easier to set alight. It needs degreasing rather than brushing, and in a house with a traditional open cooking chimney the two flues are usually swept at the same visit. Say which one you mean when you ask for a quote.
