About our external mastic in Balcombe
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We’re often asked to deal with movement joints filled with mortar instead of sealant and old sealant gone brittle and cracked, across concrete & block, joints between brick and frames and copings & trims.
Around Balcombe, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
Every job comes with our 12-month guarantee, wherever you are in West Sussex.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
What external mastic looks like in Balcombe
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Tyes Place (about 2.1 miles south-west) are a reminder that the area around Balcombe has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For landlords with property near Balcombe station, outside joints that have cracked can let damp into a rental, so check them between lets. If you live in an older home near The Parish Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.

How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. For a village or hamlet like Balcombe, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit
- Mention any tricky access

Advice
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Letting agents and landlords in Balcombe can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Balcombe: your questions answered
Will you come out to Balcombe?
Yes. Balcombe is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Common problems we fix in Balcombe
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
These are the problems we are asked about most:
- Weeds or debris growing in open joints
- Failed sealant between panels on a façade
- Old sealant gone brittle and cracked
- Movement joints with cracked, split or missing sealant
Managing a site like Balcombe CofE Controlled Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include
- What guarantee comes with the work
- Whether all the old sealant comes out first
- Who turns up on the day
- Whether the sealant suits the joint
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Tell anyone working on the walls about the movement joints
- Wash walls gently around the sealant
- Get split or bare joints resealed while the damage is small
- Clear growth from the base of walls and joints
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage.
