External mastic in Great Bromley, done properly
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’ll confirm what’s needed to reach them safely. We work on façade panels, concrete & block and render & cladding joints, and common reasons people get in touch are old sealant gone brittle and cracked and damp patches traced to an open external joint.
Around Great Bromley, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

How the job changes by surface
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Render that is blown, hollow or coming away
- Walls that need new movement joints cut into them
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.
What we seal
- Façade panels

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Why it’s worth doing now in Great Bromley
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. In a small place like Great Bromley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.

Outside joints around Great Bromley
Historic houses like Castle House (about 4 miles north) are a reminder that the area around Great Bromley has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St George include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like St George's Church of England Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Alresford station, outside joints that have cracked can let damp into a rental, so check them between lets.

Are you insured?
Yes, we’re fully insured for every job we do.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Where are you based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
