Our Story

The oldest name in London chimney sweeping

Naish & Sons was established in 1870, when the chimneys of London were still swept from a horse-drawn cart. More than 150 years later we are the oldest established family-run chimney sweeps in London, and the name over the door has never changed.

The trade has been passed from father to son through five generations of the Naish family. The brushes, the methods and the vans have moved with the times, but the way we work has not: turn up when we say we will, leave the room cleaner than we found it, and treat every customer as part of the family rather than a number in a diary.

Today the business is run by Alan Naish and his son Dean from Coulsdon. The photograph we carry on the back of our van shows Alan's own father with his son, brushes in hand. Father and son then, father and son now, carrying the same name, the same standards and the same pride in the craft. It is not just a job to us. It is the family story.

Expert advice on your fire and flue

Bird Nest Removal

A nest can block the flue, letting dangerous gases into the house and raising the risk of a chimney fire. Nests are also a common cause of damp on the ceiling or chimney breast. We remove them safely and check the flue is clear.

All Flues & Chimneys Swept

Whatever the age or type of your chimney, regular sweeping protects your health, prevents chimney fires and avoids smoke damage to your rooms.

Wood Burners & Open Fires

We sweep and check wood burning stoves and open fires, making sure yours is clean, drawing properly and safe to light all season.

Why It Matters

Regular sweeping keeps you safe

Carbon monoxide can kill. Heating and cooking appliances fuelled by wood, coal, oil or gas can cause poisoning if they are poorly installed or not properly maintained.

The risk is reduced by having your chimney or flue swept regularly, not overloading the fire, keeping rooms well ventilated and fitting a carbon monoxide alarm that you test often. When we visit, we will happily advise on all of it.

WoodSweep quarterly when in use

CoalSweep twice a year

Where We Work

From terraced houses to country homes

No two chimneys are the same. In one week we might sweep a Victorian terrace, a wood burner in a modern extension and the tall stacks of a listed country house. Whatever is on the roof, it gets the same careful, no-mess treatment.

We are based in Coulsdon and cover the whole of south London. If you are not sure whether we reach you, ring us and ask. Get booked in before the winter rush.

“Great service, unbelievably rescued two fully grown Mallards from our wood burner chimney. We were shocked, but sweep handled the whole thing brilliantly.”
