External mastic for homes and businesses in Hellman's Cross
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. If you have hard, crazed mastic that has stopped moving and sealant that has lost its bond to the brick or render, we can help, on brickwork movement joints, copings & trims and joints between brick and frames alike.
Somewhere as small as Hellman's Cross, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Show decorators and builders where the movement joints are
- Avoid pressure-washing directly into sealant joints
- Keep movement joints as flexible joints, not mortar
- Keep soil, plants and ivy away from the joints
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back.

Different surfaces, different methods
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best year round.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
What we are called out for in Hellman's Cross
Some movement joints have been pointed up with mortar. The joint can’t move, so the wall cracks somewhere else instead.
It’s worth asking for a quote if you see:
- Damp patches traced to an open external joint
- Sealant pulling away from one side of the joint
- Plants rooting in failed movement joints
- Failed seals between different materials
Letting a property close to Stansted Airport station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Advice
What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems
- Rising or penetrating damp from elsewhere in the wall
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal
- Brickwork movement joints
- Façade panels
- Copings & trims
- Render & cladding joints
- Joints between brick and frames
- Concrete & block
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
