How we handle external mastic in Oakshott
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 mortar or filler would crack. If you are dealing with damp patches traced to an open external joint and leaking joints around cladding and façade panels, we can put it right, whatever the surface.
In a village or hamlet like Oakshott, 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.
All our work comes with a one-year guarantee, wherever you are in Hampshire.

How it works
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Oakshott, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- On commercial sites, let us know about site rules

What else we do in Oakshott
Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Around Oakshott, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

External mastic in Oakshott: local notes
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.
Letting a property close to Liss station? Then outside joints that have cracked can let damp into a rental, so check them between lets. If you live in an older home near Church of St Peter and St Paul, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full 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.
Surface by surface
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Adding movement joints to masonry that has none
- Damp that isn’t coming from the joint
- Movement that is more than a sealant joint can take
If in doubt, call 0345 464 0079 or email us and we will say what we think before booking.
