External mastic in Wimbish
Low-level joints can usually be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. Typical jobs include cracked joints where brick meets render or frames and water getting into walls through failed joints, on joints between brick and frames, façade panels and brickwork movement joints.
External sealant needs dry, clean surfaces, so work around Wimbish is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
Your job is guaranteed for a year, as with all our work.

The process
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases. Somewhere like Wimbish needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Clear the area around the work
- Let us know about parking restrictions
- Tell us about any water getting in

External mastic in Wimbish: local notes
Historic houses like Horham Hall (about 4.1 miles south) are a reminder that the area around Wimbish 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Wimbish Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Newport (Essex) station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as St Paul's Mission Room, the joints between older walls, newer extensions and the roofline need a sealant that can move.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Keep movement joints as flexible joints, not mortar
- Get split or bare joints resealed while the damage is small
- Point out the joints to other trades
- Avoid pressure-washing directly into sealant joints
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
What happens if it’s left?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In a small place like Wimbish, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Subsidence or other structural problems
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.
