About our external mastic in St Osyth Heath
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the joint does not stand out. We’re often asked to deal with rain getting behind render or cladding at a joint and weeds or debris growing in open joints, across concrete & block, joints between brick and frames and render & cladding joints.
In a village or hamlet like St Osyth Heath, 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.
We stand behind the work with a one-year guarantee.

Different surfaces, different methods
Cladding and façade panels
If the façade has a specified sealant, that is what we use. Send us any details you have about the façade.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
St Osyth Heath buildings and the weather
St Osyth Heath is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Tendring Enterprise Studio School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Thorpe Hall, about 3.4 miles north-east, is one of the historic houses in the wider area around St Osyth Heath.
St Osyth Heath is about 2 miles north-west of Clacton-on-Sea, in Essex. Jobs in St Osyth Heath get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee. Our Essex coverage runs to 644 places, and St Osyth Heath is one of them. You can also see our page for Chelmsford, about 27 miles away.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Ask before painting over external sealant
- Walk round the building once a year and look at the joints
- Keep movement joints as flexible joints, not mortar
- Wash walls gently around the sealant
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render, so the problem grows beyond the joint itself. Around St Osyth Heath, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

What happens on the day
The work is kept neat and contained to the area we’re working on, so you can get on with your day. The job usually takes a few hours to a few days, depending on the length of joint and the access, and we tell you how long to leave it before we go. In a small place like St Osyth Heath, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work

What we’re called out for in St Osyth Heath
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
Keep an eye out for these signs:
- Sealant pulling away from one side of the joint
- Movement joints with cracked, split or missing sealant
- Water getting into walls through failed joints
- Weeds or debris growing in open joints
For landlords with property near Weeley station, outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before you book
- The length of the guarantee
