- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Subsidence or other structural problems
- Cracking across the wall rather than at a joint

External mastic in Roydon Hamlet, done properly
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. If you have plants rooting in failed movement joints and rigid filler in a joint that should flex, we can put it right.
Around Roydon Hamlet, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.

Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Older cottages and farmhouses around Roydon Hamlet can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Roydon Hamlet buildings and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of All Saints, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Roydon station, split movement joints are easy to miss on a rental until damp shows inside.

What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Roydon Hamlet, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.

Different surfaces, different methods
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.

What else we do in Roydon Hamlet
Common problems we fix in Roydon Hamlet
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
Any of these means the joints need attention:
- Failed sealant between panels on a façade
- Joints where the bead has come unstuck
- Rain getting behind render or cladding at a joint
- Movement joints with cracked, split or missing sealant
For site and facilities teams at buildings such as Roydon Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Wash walls gently around the sealant
- Do not let climbing plants root in the sealant
- Keep water from gutters off the wall
- Get split or bare joints resealed while the damage is small
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
