How we handle external mastic in Wiston
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. We work on façade panels, render & cladding joints and joints between brick and frames, and people most often call us about panel joints letting water in and brick movement joints where the sealant has split.
In a village or hamlet like Wiston, 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.
All our work comes with our 12-month guarantee, wherever you are in West Sussex.

Aftercare tips
A little care helps the new joints last. We recommend:
- Walk round the building once a year and look at the joints
- Deal with leaking gutters that soak the joints below
- Clear growth from the base of walls and joints
- Tell anyone working on the walls about the movement joints
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.
Small splits are the time to act. At that stage it’s a simple cut out and reseal.

Are you fully insured?

I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Can you reach joints on upper floors?
Each building is different. Send us photos and a rough idea of the height.
Is it OK to fill a movement joint with cement?
No. Cement or mortar cannot stretch. Where a joint has been mortared, it can often be raked out and sealed properly.
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
External mastic in Wiston: local notes

Signs you need external mastic in Wiston
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
If you can see any of these, it’s time to have the joints looked at:
- Rigid filler in a joint that should flex
- Rain getting behind render or cladding at a joint
- Weathered mastic that no longer stretches
- Sealant pulling away from one side of the joint
If you live in an older home near All Saints Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of joints, longer for a whole elevation, and the area is left clean. Somewhere like Wiston needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints

Advice
What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. In a small place like Wiston, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Damp that is not coming from the joint
- Adding movement joints to masonry that has none
- Structural movement, which needs a surveyor or engineer
