Outside joints around Shripney
Shripney is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Bersted Green Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as Holy Cross Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

About our external mastic in Shripney
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. We work on brickwork movement joints, concrete & block and joints between brick and frames, and common reasons people get in touch are movement joints with cracked, split or missing sealant and cracked joints where brick meets render or frames.
Somewhere as small as Shripney, homes and farm buildings often face open ground, 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.
Whatever the size of the job, you get the same one-year guarantee.

What else we do in Shripney
What we are called out for in Shripney
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.
Signs it’s time to call us include:
- Rain getting behind render or cladding at a joint
- Plants rooting in failed movement joints
- Weathered mastic that no longer stretches
- Failed seals between different materials
If you let a flat or house near Bognor Regis station, outside joints that have cracked can let damp into a rental, so check them between lets.

Why deal with it now?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Around Shripney, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
Why choose Mr Mastic in Shripney
- Sealant colour chosen to suit
- Experience in homes, commercial sites and hotels
- Trusted Arbo and Everbuild sealants
- Over 20 years’ experience
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
When something else is needed
It helps to know what we cannot do too:
- Cracks in the bricks or render themselves, away from the joints
- Loose or hollow render, which needs re-rendering
- Walls that need new movement joints cut into them
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
