Chimney Rendering in Kent
Rendering, repointing and weatherproofing chimney stacks — the most exposed masonry on any house.
Kent property owners come to us for chimney rendering for one of two reasons: something has failed, or the house looks tired.
Most of what we see around Kent reflects the wider Kent pattern — ragstone and flint cottages, oast houses, Victorian terraces and coastal housing, and coastal weathering at Margate and Dover, lime work on ragstone. With drier than average inland, exposed on the coast, specification matters more in this part of the country than a national price list suggests.
Local factor. Kentish ragstone is porous and traditionally lime-rendered, while the north kent coast takes some of the most persistent easterly exposure in the south east.
Is chimney rendering right for a Kent property?
Choose chimney rendering where a stack is spalling, the pointing has failed, or damp is showing in upstairs rooms near a chimney breast.
That decision gets made at the survey, not on the phone. We will tell you plainly if a different system would serve the building better — including when a cheaper one would.

FAQs
Chimney Rendering in Kent — questions
Why is my chimney causing damp?
Water enters through failed flaunching, cracked render, open pointing or defective flashings, then runs down inside the flue and shows as staining on a chimney breast, often on the floor below.
What is flaunching?
The mortar fillet that beds the chimney pots into the top of the stack and sheds water off it. It cracks and fails with age and is a very common leak point.
How much does rendering cost?
It is priced by the square metre and depends on the system, the condition of the walls and access. Our guide-price tool gives an indicative range in about a minute, and the survey turns that into a fixed written quote.
Do you offer a guarantee?
Yes. Every job carries our workmanship guarantee, and where a full manufacturer-specified system is installed you also get the system warranty on top.
What time of year is best for rendering?
Spring through autumn is ideal. Render should not be applied in frost or in very hot direct sun, so winter work needs protection and settled conditions.
Can you render over existing render?
Sometimes, if the existing coat is completely sound and well-bonded. We hammer-test it first. Anything hollow has to come off, because covering failure just hides it.
