Advice
External mastic in Little Canfield
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. We work on copings & trims, brickwork movement joints and render & cladding joints, and the jobs we see most are old sealant gone brittle and cracked and damp patches traced to an open external joint.
In a village or hamlet like Little Canfield, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Big or small, you get the same 12-month guarantee in Little Canfield and across Essex.

Why deal with it now?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Older cottages and farmhouses around Little Canfield can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.

When something else is needed
In fairness, there are a few things sealant won’t fix:
- Walls that need new movement joints cut into them
- Failed render or damaged cladding panels
- Structural movement, which needs a surveyor or engineer
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Never let anyone fill a movement joint with mortar
- Check the sealant is paintable before painting near it
- Walk round the building once a year and look at the joints
- Avoid pressure-washing directly into sealant joints
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What external mastic looks like in Little Canfield
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Barrington Hall (about 2.8 miles south-west) nearby, there’s older building stock in the area around Little Canfield as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Stansted Airport station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near Church of All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Takeley Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Surface by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap and keep the sealant to the right depth.
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
