- Sealant that has lost its bond to the brick or render
How we handle external mastic in Cramhurst
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. Typical jobs include plants rooting in failed movement joints and failed seals between different materials, on joints between brick and frames, copings & trims and concrete & block.
Around Cramhurst, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
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.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Have failed joints looked at early
- Keep water from gutters off the wall
- Check external joints each spring
- Wash walls gently around the sealant
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.

We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Surface by surface
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and helps it last.
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.

Cramhurst buildings and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Loseley Park (about 4.4 miles north-east) nearby, there’s older building stock in the area around Cramhurst as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For an older house near a landmark such as St John the Evangelist's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Why deal with it now?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Around Cramhurst, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
Do you need external mastic in Cramhurst?
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Look out for any of the following:
- Sealant that has lost its bond to the brick or render
- Plants rooting in failed movement joints
- Failed sealant between panels on a façade
- Failed seals between different materials
Letting a property close to Milford (Surrey) station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
