How we handle external mastic in Swaile's Green
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We work on brickwork movement joints, render & cladding joints and copings & trims, and people most often call us about failed seals between different materials and old sealant gone brittle and cracked.
Around Swaile's Green, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
Whatever the size of the job, you get the same one-year guarantee in Swaile's Green and across East Sussex.

Common problems we fix in Swaile's Green
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
Any of these means the joints need attention:
- Rain getting behind render or cladding at a joint
- Rigid filler in a joint that should flex
- Cracked joints where brick meets render or frames
- Leaking joints around cladding and façade panels
Schools such as Staplecross Methodist Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Swaile's Green questions
Is Swaile's Green within the area you cover?
Yes. Swaile's Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do external mastic in Swaile's Green?
Yes. We work across London and the South East, and Swaile's Green is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render. There’s a wide choice of exterior colours.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
What the job involves on each surface
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible year round.
Looking after it afterwards
Aftercare is simple:
- Leave the joints unpainted unless we’ve said otherwise
- Show decorators and builders where the movement joints are
- Have failed joints looked at early
- Look over the joints every year, ideally after winter
Keep pressure washers away from the sealant. High-pressure water can lift the edges over time.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

Why act early in Swaile's Green
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Older cottages and farmhouses around Swaile's Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

What external mastic looks like in Swaile's Green
London and the South East are among 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 Durhamford Manor (about 1.2 miles south) nearby, there’s older building stock in the area around Swaile'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.
Rented homes near Robertsbridge station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to St Marks Staplecross include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
