NACS registered chimney sweeping for open fires across Greater Manchester, Cheshire and Lancashire. Traditional or power sweeping, free smoke draw test, certificate issued on the day. From £75.
An open fire draws a great deal more air than a stove, and it burns through a lot more fuel for the heat it gives out. That means more soot, faster — and in a chimney that is often wide, tall and unlined.
Older open fire chimneys also tend to be the ones that have been in service longest. Wide throats, long flue runs, sometimes failing parging, and in terraced property the occasional flue that turns out to be shared or crossed with next door. These are not chimneys to rush.
Reopened fireplaces
The single most common open fire job we get called to is a fireplace that was blocked off during the central heating years and has since been opened back up. A flue that has been out of service for thirty or forty years needs sweeping and a draw test before it is lit — not after the room fills with smoke.
Assume nothing about what is up there. Old soot falls, debris and nests are all common.
Sweep and draw test before first use, not after
Old soot falls and loose debris are routine in long-dormant flues
Jackdaw nests are a total blockage and a carbon monoxide risk
Failing parging in unlined chimneys needs identifying early
What we do
Check the stack before we start
Sweep traditionally or by power sweeping, whichever the flue needs
HEPA filtered industrial vacuum running throughout — no dust in your room
Free smoke draw test
NACS Certificate of Chimney Sweeping
No mess, and a certificate your insurer accepts
Sheets down before we start and a HEPA filtered industrial vacuum running throughout. Every job includes a free smoke draw test and a NACS Certificate of Chimney Sweeping — which matters, because most insurers will no longer pay out on chimney fire damage without one.
Sweep once a season if you are burning wood, twice a year on bituminous coal, and at least once a year on smokeless fuel. If your fire has started smoking back, it is often not the chimney at all — new windows, doors or draught-proofing seal the house up and the fire has nowhere to draw air from.
An open fire needs an air opening of at least 50% of the throat area — usually around 16,500mm² for a typical fireplace.
There is more on fuels, moisture content and ventilation on our safety advice page.
Our other services
Whichever appliance you have, the standard is the same.
It might be, but ventilation is the more common cause — particularly if the house has recently been draught-proofed or had new windows fitted. Our smoke draw test will tell us which it is.
Please do not. Have it swept and draw tested first. A flue that has been out of service for decades is the one most likely to throw up something unexpected.
From £75, including the free smoke draw test and the certificate. A chimney that has not been swept in many years may take longer — tell us when you book and we will allow the time.
