External & façade joints in Bulverhythe, East Sussex

External mastic in Bulverhythe, done properly
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We work on render & cladding joints, joints between brick and frames and façade panels, and the jobs we see most are leaking joints around cladding and façade panels and joints pointed up with cement by mistake.
Around Bulverhythe, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
Whatever the size of the job, you get the same 12-month guarantee in Bulverhythe and across East Sussex.

What happens on the day
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work starts. The work generally takes anything from a few hours to several days, depending on the building. For a village or hamlet like Bulverhythe, 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.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Clear items away from the joints we’re working on
- Let us know about parking restrictions

External mastic in Bulverhythe: local notes
Bulverhythe is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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.
If you look after a building such as The St Leonards Academy, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to West St Leonards station? Then split movement joints are easy to miss on a rental until damp shows inside.
Bulverhythe is about 1 mile west of St Leonards, in East Sussex.

Different surfaces, different methods
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best in all weathers.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap so the sealant isn’t too deep.
How to look after the new joints
After the cure time, these simple habits help:
- Never let anyone fill a movement joint with mortar
- Wash walls gently around the sealant
- Leave the joints unpainted unless we have said otherwise
- Deal with leaking gutters that soak the joints below
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost around the joint, so the damage spreads beyond the joint. In a small place like Bulverhythe, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

When to call us in Bulverhythe
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Most people get in touch when they notice one of these:
- Rain getting behind render or cladding at a joint
- Gaps where render, brick and frames meet
- Joints with sealant missing in places
- Moss and dirt in joints with no sealant left
If you live in an older home near St Ethelburga's Church Mission Hall, an extension built onto an older house moves differently, and the joint between them takes the strain.

When it is not the sealant
We won’t take on work that won’t last, so here’s what sealant cannot put right:
- Structural movement, which needs a surveyor or engineer
- Loose or hollow render, which needs re-rendering
- Damp that isn’t coming from the joint

Questions from Bulverhythe
Do you cover smaller places like Bulverhythe?
Yes, Bulverhythe is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is external mastic in a coastal place like Bulverhythe any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
What is a movement joint?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move and needs a flexible seal, not mortar.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so the joint does not draw the eye.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges.
