External mastic in Little London: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Andover station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Smannell and Enham Church of England (Aided) Primary School, larger buildings have long runs of movement joint that eventually need resealing.

External mastic in Little London, done properly
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. We work on render & cladding joints, copings & trims and joints between brick and frames, and the jobs we see most are old sealant gone brittle and cracked and movement joints filled with mortar instead of sealant.
In a village or hamlet like Little London, older cottages and farm buildings often stand in the open, 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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Advice
Common problems we fix in Little London
Some movement joints have been pointed up with mortar. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Any of these means the joints need attention:
- Movement joints with cracked, split or missing sealant
- Damp patches traced to an open external joint
- Joints where the bead has come unstuck
- Leaking joints around cladding and façade panels
In the older streets around Christ Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Surface by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so the movement is taken up.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant.
When it is not the sealant
We won’t take on work that won’t last, so these are the limits:
- Damp that isn’t coming from the joint
- Cracked brickwork or render that needs a builder or plasterer
- Walls that need new movement joints cut into them
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.
Surfaces we seal
- Brickwork movement joints
- Render & cladding joints
- Façade panels
- Concrete & block
- Joints between brick and frames
- Copings & trims
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Little London: your questions answered
Can you help a landlord with a rental near Andover station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Will you come out to Little London?
Yes, Little London is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you seal joints between render and window frames?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
Do you work at height?
It depends on the height and the site. Ground-floor joints are simple; for higher ones, send details and we’ll confirm the access.
Is it OK to seal over old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Can a movement joint be filled with mortar?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose, and the wall may crack nearby. We will reseal it with a flexible sealant.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before we start, matched as closely as the range allows.
Leave it or put it right?
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 doesn’t last. Older cottages and farmhouses around Little London can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.
