- Leaking joints around cladding and façade panels
- Plants rooting in failed movement joints
External mastic in Crouch
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where a rigid filler would soon crack. We work on brickwork movement joints, joints between brick and frames and concrete & block, and common reasons people get in touch are joints pointed up with cement by mistake and weeds or debris growing in open joints.
In a village or hamlet like Crouch, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Whatever the size of the job, you get the same 12-month guarantee in Crouch and across Kent.

What we’re called out for in Crouch
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Look out for any of the following:
- Cracked joints where brick meets render or frames
- Panel joints letting water in
- Joints with sealant missing in places
- Moss and dirt in joints with no sealant left
If you live in an older home near Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Crouch questions
Will you come out to Crouch?
Yes. Crouch is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Borough Green & Wrotham station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly and reseal when it splits.
Can you do several jobs on one visit?
Yes. Just list everything you need and we will quote it together.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
What happens if it’s left?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last, so it pays to do it properly once. Older cottages and farmhouses around Crouch can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start.

When it is not the sealant
To be straight with you, some problems need a different trade:
- Cracks in the bricks or render themselves, away from the joints
- Render that is blown, hollow or coming away
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Surfaces we seal
- Concrete & block
- Façade panels
- Render & cladding joints
- Joints between brick and frames

How the visit works
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. For a village or hamlet like Crouch, 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.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

External mastic in Crouch: local notes
Historic houses like Old Soar Manor (about 1 mile south) are a reminder that the area around Crouch 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. 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.
Letting a property close to Borough Green & Wrotham station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Borough Green Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

DIY versus a professional finish
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 fails, we can still redo it.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Different surfaces, different methods
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it.
