About our external mastic in Spurlands End
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We work on render & cladding joints, brickwork movement joints and façade panels, and the jobs we see most are failed seals between different materials and movement joints filled with mortar instead of sealant.
In a village or hamlet like Spurlands End, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Aftercare tips
So the new joints stay in good condition:
- Make sure movement joints aren’t pointed over
- Act on the first splits you see
- Wash walls gently around the sealant
- Look over the joints every year, ideally after winter
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.
Questions from Spurlands End
Will you come out to Spurlands End?
Yes, Spurlands End is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Spurlands End for external mastic?
Yes, Spurlands End is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
Is it OK to fill a movement joint with cement?
No. Cement or mortar cannot stretch, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Is there a guarantee?
Yes. Every job comes with a 12-month guarantee.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Different surfaces, different methods
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
Cladding and façade panels
Cladding and façade panels are normally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Movement that is more than a sealant joint can take
- Damp that is not coming from the joint
- Failed render or damaged cladding panels
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
Surfaces we seal
- Façade panels
- Concrete & block
- Copings & trims
- Joints between brick and frames

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Walls and rooflines in Spurlands End
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Hughenden Manor (about 2.5 miles south-west) are a reminder that the area around Spurlands End has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For landlords with property near Great Missenden station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as Church of the Good Shepherd, an extension built onto an older house moves differently, and the joint between them takes the strain.

Common problems we fix in Spurlands End
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
People usually contact us when they notice one of these:
- Leaking joints around cladding and façade panels
- Plants rooting in failed movement joints
- Hard, crazed mastic that has stopped moving
- Sealant pulling away from one side of the joint
If you look after a building such as Holmer Green First School and Pre-School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

- What preparation is included
What happens if it’s left?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. Where a wall is exposed, as many are in small places like Spurlands End, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before work begins.
