Aftercare tips
Once the sealant has cured, a few habits help it last:
- Do not let climbing plants root in the sealant
- Point out the joints to other trades
- Keep high-pressure jets off the joints
- Get split or bare joints resealed while the damage is small
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
External mastic in Flackley Ash
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 mortar or filler would crack. We work on brickwork movement joints, render & cladding joints and façade panels, and common reasons people get in touch are rigid filler in a joint that should flex and sealant pulling away from one side of the joint.
External sealant needs dry, clean surfaces, so work around Flackley Ash is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
All our work comes with a one-year guarantee.

What external mastic looks like in Flackley Ash
Historic houses like Lamb House (about 3.2 miles south-east) are a reminder that the area around Flackley Ash has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Rye station? Then split movement joints are easy to miss on a rental until damp shows inside. Homes close to The Parish Church of St Peter and St Paul include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Common problems we fix in Flackley Ash
Sometimes a movement joint was filled with mortar or a rigid filler. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Signs it’s time to call us include:
- Movement joints filled with mortar instead of sealant
- Sealant that has lost its bond to the brick or render
- Plants rooting in failed movement joints
- Joints with sealant missing in places
For site and facilities teams at buildings such as Peasmarsh Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.
