Trusted external mastic in Hampton Poyle

Leave it or put it right?

A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Older cottages and farmhouses around Hampton Poyle can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

External mastic in Hampton Poyle, done properly

External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. Typical jobs include movement joints with cracked, split or missing sealant and sealant that has lost its bond to the brick or render, on joints between brick and frames, brickwork movement joints and copings & trims.

Older homes in small places like Hampton Poyle may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

When to call us in Hampton Poyle

Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.

Common reasons people contact us include:

  • Panel joints letting water in
  • Plants rooting in failed movement joints
  • Failed seals between different materials
  • Old sealant gone brittle and cracked

For an older house near a landmark such as Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Hampton Poyle buildings and the weather

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Blenheim Palace (about 3.9 miles west) are a reminder that the area around Hampton Poyle has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.

Letting a property close to Islip station? Then split movement joints are easy to miss on a rental until damp shows inside. Schools such as Gosford Hill School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

DIY versus a professional finish

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

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.

Aftercare tips

No joint lasts for ever, but care makes a real difference. A few tips:

  • Keep movement joints as flexible joints, not mortar
  • Show decorators and builders where the movement joints are
  • Deal with leaking gutters that soak the joints below
  • Avoid pressure-washing directly into sealant joints

Avoid pressure-washing straight into the joints. High-pressure water can lift the edges.

Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
