How we handle external mastic in Hoe Gate
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. If you have movement joints with cracked, split or missing sealant and old sealant gone brittle and cracked, we can put it right, whatever the surface.
Around Hoe Gate, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
Big or small, it’s backed by our 12-month guarantee.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Keep movement joints as flexible joints, not mortar
- Deal with leaking gutters that soak the joints below
- Ask before painting over external sealant
- Point out the joints to other trades
Keep pressure washers away from the sealant. High-pressure water can lift the edges and let water in behind.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

When to call us in Hoe Gate
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and tears as soon as the joint widens.
These are the problems we are asked about most:
- Movement joints filled with mortar instead of sealant
- Plants rooting in failed movement joints
- Gaps where render, brick and frames meet
- Panel joints letting water in
In the older streets around Church of the Holy Trinity, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
The process
The work is kept neat and contained to the area we’re working on, so you can get on with your day. The job generally takes a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. For a village or hamlet like Hoe Gate, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- On commercial sites, let us know about site rules
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints

What we cannot put right
In fairness, there are a few things sealant won’t fix:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Movement that is more than a sealant joint can take
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before you book.

Hoe Gate buildings and 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 let a flat or house near Portchester station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as Newtown Soberton Infant School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
