Shoreham: your questions answered
Do you cover smaller places like Shoreham?
Yes, Shoreham is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is Shoreham in your area for external mastic?
Yes. We work across London and the South East, and Shoreham is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing.
Do you work at height?
It depends on the building. Tell us the height, the number of joints and what’s below them.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is usually a movement joint. It gives the wall room to move.
Can a movement joint be filled with mortar?
No, not if it’s a movement joint. Pointing it stops it working and can lead to cracking. We will reseal it with a flexible sealant.
How much does external mastic cost in Shoreham?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Can tenants book the work?
Of course. Ask your landlord first, and we can send them the quote if that helps.
External mastic in Shoreham, done properly
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 colour to suit. We’re often asked to deal with movement joints with cracked, split or missing sealant and moss and dirt in joints with no sealant left, across façade panels, brickwork movement joints and concrete & block.
In a village or hamlet like Shoreham, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Point out the joints to other trades
- Get split or bare joints resealed while the damage is small
- Keep high-pressure jets off the joints
- Keep soil, plants and ivy away from the joints
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges and let water in behind.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Why deal with it now?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a small place like Shoreham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What else we do in Shoreham
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
External mastic in Shoreham: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Lullingstone Castle (about 1.8 miles north-east) nearby, there’s older building stock in the area around Shoreham as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around Church of St Peter and St Paul, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as Shoreham Village School, larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Shoreham (Kent) station, outside joints that have cracked can let damp into a rental, so check them between lets.

What happens on the day
On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. The work generally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Shoreham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed

How the job changes by surface
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly.
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible year round.
