External Mastic in Bow Common
We cover Bow Common for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Moss and dirt in joints with no sealant left
- Weathered mastic that no longer stretches
- Rain getting behind render or cladding at a joint
How the job changes by surface
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
External mastic in Bow Common
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. If you are dealing with joints pointed up with cement by mistake and failed sealant between panels on a façade, we can help, on render & cladding joints, copings & trims and concrete & block alike.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall, and both kinds of building are found across London.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Looking after it afterwards
So the new joints stay in good condition:
- Keep water from gutters off the wall
- Get split or bare joints resealed while the damage is small
- Clear growth from the base of walls and joints
- Check external joints each spring
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.

Signs you need external mastic in Bow Common
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Any of these means the joints need attention:
- Movement joints filled with mortar instead of sealant
- Weathered mastic that no longer stretches
- Water getting into walls through failed joints
- Sealant pulling away from one side of the joint
As a London address, Bow Common can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Bow Common, the repair is bigger than a sealant job.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
