External Mastic in Wickford
Our applicators work in Wickford on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Cracked joints where brick meets render or frames
- Water getting into walls through failed joints
- Joints where the bead has come unstuck
External mastic in Wickford
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where a rigid filler would soon crack. If you are dealing with movement joints filled with mortar instead of sealant and damp patches traced to an open external joint, we can put it right, whatever the surface.
In a town like Wickford, older houses with traditional gutters sit alongside newer estates with uPVC rooflines and rendered walls. Gutter joints, fascia trims and the movement joints in newer brickwork all need sealant that can flex.
Each job carries a 12-month guarantee, whatever its size.

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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.
External mastic in Wickford: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Oakfield Primary School, its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Wickford station, split movement joints are easy to miss on a rental until damp shows inside. Homes close to St Andrew include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Common questions in Wickford
Is external mastic in Wickford guaranteed?
All our work, in Wickford and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Can you do external mastic in Wickford?
Yes. We work across London and the South East, and Wickford is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall. There’s a wide choice of exterior colours.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or send us an email.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
What is a movement joint?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Do you have insurance?
Yes. Mr Mastic is fully insured.
When it isn’t the sealant
In fairness, there are a few things sealant won’t fix:
- Loose or hollow render, which needs re-rendering
- Walls that need new movement joints cut into them
- Cracking across the wall rather than at a joint
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

Leave it or put it right?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. In a family home in Wickford, a failed seal around a bath or a frame lets water into places you cannot see, such as under the floor, behind a panel or into a wall. Left alone, that means rot, damp and a bigger repair.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear price before work begins.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Tell anyone working on the walls about the movement joints
- Keep high-pressure jets off the joints
- Keep movement joints as flexible joints, not mortar
- Keep soil, plants and ivy away from the joints
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.

What we do, step by step
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for a handful of joints, longer for a whole elevation from start to finish. For a job in Wickford, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts

How the job changes by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
