External & façade joints in South Chingford, Greater London
Problem with your movement joints in South Chingford? We remove the old material, prepare the joints and seal them properly.
- Water getting into walls through failed joints
- Cracked joints where brick meets render or frames
- Plants rooting in failed movement joints
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
External mastic in South Chingford
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. We work on brickwork movement joints, joints between brick and frames and façade panels, and common reasons people get in touch are gaps where render, brick and frames meet and failed sealant between panels on a façade.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. For a home in South Chingford, tell us how high the joints are and how to reach the back of the building.
Each job carries a 12-month guarantee.

When something else is needed
Sealant isn’t the answer to every problem, and we will tell you before we start. It will not solve:
- Cracked brickwork or render that needs a builder or plasterer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Loose or hollow render, which needs re-rendering
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.
Surfaces we seal
- Brickwork movement joints
- Joints between brick and frames
- Render & cladding joints
- Concrete & block
- Façade panels
- Copings & trims
Why act early in South Chingford
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together and it means sorting access once. In a flat in South Chingford, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

How to look after the new joints
So the new joints stay in good condition:
- Keep high-pressure jets off the joints
- Ask before painting over external sealant
- Make sure movement joints are not pointed over
- Tell anyone working on the walls about the movement joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.

Common problems we fix in South Chingford
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
The most common problems we see are:
- Moss and dirt in joints with no sealant left
- Rain getting behind render or cladding at a joint
- Joints pointed up with cement by mistake
- Hard, crazed mastic that has stopped moving
Managing a site like Chingford Hall Primary Academy? Then larger buildings have long runs of movement joint that eventually need resealing.

Outside joints around South Chingford
With historic houses such as Bruce Castle (about 2.2 miles west) nearby, there’s older building stock in the area around South Chingford as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts.
As a London address, South Chingford can be tricky for parking: let us know about parking bays, permits or a driveway. If you live in an older home near St Edmund's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
