External mastic for homes and businesses in Bishop's Green
Low-level joints can usually be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. We are often asked to deal with joints where the bead has come unstuck and weeds or debris growing in open joints, on render & cladding joints, concrete & block and joints between brick and frames.
Older homes in small places like Bishop's Green may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
A one-year guarantee comes as standard, so you are covered after we have gone.

Do you need external mastic in Bishop's Green?
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
The most common problems we see are:
- Sealant that has lost its bond to the brick or render
- Gaps where render, brick and frames meet
- Weeds or debris growing in open joints
- Weathered mastic that no longer stretches
Rented homes near Newbury Racecourse station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

What the job involves on each surface
Cladding and façade panels
Cladding and façade panels are normally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly.
How to look after the new joints
To keep the joints looking good and working properly:
- Check external joints each spring
- Keep movement joints as flexible joints, not mortar
- Clear growth from the base of walls and joints
- Wash walls gently around the sealant
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

Outside joints around Bishop's Green
With historic houses such as Shaw House (about 3.6 miles north-west) nearby, there’s older building stock in the area around Bishop's Green as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Cheam School, larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near Church of St Peter, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Advice
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Bishop's Green questions
Is Bishop's Green within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Newbury Racecourse station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Can a movement joint be filled with mortar?
No. Cement or mortar can’t stretch and the joint fails. If it has already been filled, we can generally cut it out and reseal it.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
What information do you need?
A short description and the location, with pictures by email if possible. We’ll ask anything else we need to know.
