About our external mastic in Leigh
Movement joints let brickwork, render and cladding expand and shrink without cracking. 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. If you are dealing with rain getting behind render or cladding at a joint and sealant pulling away from one side of the joint, we can put it right, whatever the surface.
External sealant needs dry, clean surfaces, so work around Leigh is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Leigh buildings and the weather
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 Penshurst Place (about 2 miles south-west) nearby, there’s older building stock in the area around Leigh as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around St Mary's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Leigh (Kent) station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Leigh is about 3 miles west of Tonbridge, in Kent. Leigh gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Our Kent coverage runs to 922 places, and Leigh is one of them. For nearby work, see our Crawley page (19 miles or so).

How the visit works
The work is kept neat and contained to the area we are working on, so you can get on with your day. The job normally takes a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. In a small place like Leigh, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- 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.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

Related advice
What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. Older cottages and farmhouses around Leigh can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

When to call us in Leigh
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
These are the problems we’re asked about most:
- Plants rooting in failed movement joints
- Leaking joints around cladding and façade panels
- Rigid filler in a joint that should flex
- Rain getting behind render or cladding at a joint
If you look after a building such as Leigh Primary School, larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include
- How long to leave it before use
- The length of the guarantee
- Who does the work, and how experienced they are
- Whether you can choose the colour
How the job changes by surface
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. We prime where the product needs it.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Your questions about external mastic in Leigh
Is Leigh within the area you cover?
Yes, Leigh is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Leigh (Kent) station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
How long does external mastic take?
That depends on how much there is to do, but most jobs take a few hours to a few days, depending on the length of joint and the access. We will tell you when we quote.
How do I get a quote for external mastic in Leigh?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or email us and tell us what needs doing and where.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Where do you work from?
We’re based in Crawley, and we work across South East England, London and Scotland.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or send us an email.
Honest limits
In fairness, some problems need a different trade:
- Cracked brickwork or render that needs a builder or plasterer
- Walls that need new movement joints cut into them
- Damp that isn’t coming from the joint
