Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
External mastic in Palestine
On houses, flats and commercial buildings across Palestine, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. Typical jobs include rigid filler in a joint that should flex and failed sealant between panels on a façade, across brickwork movement joints, copings & trims and concrete & block.
In a village or hamlet like Palestine, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

External mastic in Palestine: local notes
Historic houses like Idmiston Manor (about 4.7 miles south-west) are a reminder that the area around Palestine 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.
Rented homes near Grateley station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Grateley Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Landlord and commercial work in Palestine

We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Ask before painting over external sealant
- Check external joints each spring
- Have failed joints looked at early
- Make sure movement joints aren’t pointed over
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
Why it’s worth doing now in Palestine
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together. Around Palestine, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us and we will talk you through it.

What we are called out for in Palestine
Some movement joints have been pointed up with mortar by mistake. The joint can’t move, so the wall cracks somewhere else instead.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that has lost its bond to the brick or render
- Brick movement joints where the sealant has split
- Panel joints letting water in
- Rigid filler in a joint that should flex
If you live in an older home near Church of St Leonard, an extension built onto an older house moves differently, and the joint between them takes the strain.
What to look for in a quote
- Who does the work, and how experienced they are
- When the joint can take water or movement
- Whether you can choose the colour
- Whether all the old sealant comes out first
