Chimney Repointing

What Chimney Repointing Involves

Repointing means replacing the outer layer of mortar between the bricks or stones of your chimney. The bricks themselves usually last for generations, but the joints between them are the weak point. Rain, frost and wind wear them back until the mortar is recessed, sandy or missing altogether.

We rake those joints out to a sound depth, clean them and pack in fresh mortar, finishing it to the profile that suits your house. That restores the weather seal of the stack and stops water tracking through the brickwork into your chimney breast.

What’s Included

Signs Your Chimney Needs Repointing

A chimney stands above everything else on the roof, so it weathers faster than the walls below. Look for these from the garden or the street.

Mortar recessed well behind the brick face
Sand or grit collecting in the gutters
Damp patches on the chimney breast indoors
Loose or missing bricks near the top
Plants growing out of the joints
White salt staining on the brickwork
Cracked flaunching around the pots
Peeling paper or paint on a chimney breast

Getting the Mortar Right

The wrong mortar can do more harm than leaving the joints alone, so we match the mix to the chimney rather than reaching for whatever is in the van.

Lime or Cement

Older chimneys built in soft brick or stone were laid in lime mortar, which lets moisture out. Repointing those in hard cement traps water and makes the brick faces flake away.

Joint Profile

The shape of the joint affects how water runs off the face of the stack. We match the existing finish so your chimney looks like part of the house, and choose a profile that sheds rain well on exposed sides.

Mortar Colour

Fresh mortar can stand out against old brick. We adjust the sand and the mix to get as close as possible to the existing joints, so the repointed stack blends in once it has had a few weeks of weather.

FAQs

FAQs About Our Chimney Repointing Service

Answers to the things homeowners usually ask about repointing a chimney.

How often does a chimney need repointing?

There is no fixed timetable. Well-pointed brickwork on a sheltered chimney can go for decades, while an exposed stack on a coastal or hilltop house may need attention much sooner. The best guide is the joints themselves: once they are recessed or crumbling, it is time.

Can damp in my chimney breast come from the pointing?

Often, yes. Rain soaks into eroded joints and works its way down through the stack into the chimney breast, showing up as stains or peeling paint. Repointing is one possible fix, alongside checking the flaunching, the flashings and whether the chimney needs a cap or cowl.

Do you need scaffolding to repoint a chimney?

Yes, in almost every case. Repointing needs a safe, stable platform all the way round the stack for several hours of hand work, which a ladder cannot give. The cost of access is included in your written quote, so there are no extras added later.

Should I repoint or rebuild my chimney?

If the bricks are sound and the stack is upright, repointing is enough. If bricks are badly frost-damaged, the stack leans or the top courses are loose, rebuilding the upper section may be the safer option. We show you photos from the survey so you can see the condition for yourself.

Will repointing stop every leak around my chimney?

Only the ones caused by the brickwork. Water also gets in around the base through worn lead flashings and at the top through cracked flaunching. That is why we check all three on every chimney we repoint and tell you if anything else needs doing.

How It Works

How We Repoint a Chimney Stack

Repointing is slow, careful hand work, and these are the stages your chimney goes through.

Step 01

Access & Protection

We put up a chimney scaffold or roof access platform and lay boards over the surrounding tiles, so nothing is cracked by feet or falling debris.

Step 02

Rake Out the Joints

Old mortar is raked out by hand or with a fine cutter to a consistent depth, without chipping the edges of the bricks on either side.

Step 03

Clean & Dampen

Dust and loose material are brushed out of every joint and the brickwork is lightly dampened, so the new mortar bonds instead of drying out too fast.

Step 04

Repoint, Finish & Check the Top

Fresh mortar is pressed in firmly in layers, then tooled to match the joint style on the rest of the house, whether flush, bucket handle or weathered. While we are up there, we check the flaunching round the pots and the lead flashings at the base, and quote you separately for anything that needs attention.
