Surface by surface
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible year round.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
External mastic in West Silvertown, done properly
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on joints between brick and frames, façade panels and render & cladding joints, and common reasons people get in touch are sealant that has lost its bond to the brick or render and movement joints filled with mortar instead of sealant.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so one failed joint can cause damp for more than one household. In a converted house in West Silvertown, it’s worth checking who is responsible for the outside before booking.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

What we do, step by step
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in West Silvertown. It helps if you can point us to a visitor permit or a bay close to the door.
- 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.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed

What external mastic looks like in West Silvertown
London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Britannia Village Primary School, its movement joints, gutters and trims need looking after like any other building’s. West Silvertown is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

West Silvertown: your questions answered
Is parking an issue for external mastic in West Silvertown?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you work for landlords with property near Custom House station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Do you come to West Silvertown?
We do. West Silvertown is part of the area we cover, and the service is the same as everywhere else.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
How do you reach high-level joints?
It depends on the building. Tell us the height, the number of joints and what’s below them.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Check external joints each spring
- Make sure movement joints aren’t pointed over
- Check the sealant is paintable before painting near it
- Do not let climbing plants root in the sealant
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges and let water in behind.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
When something else is needed
A few problems are outside what sealant work can do:
- Cracks in the bricks or render themselves, away from the joints
- Subsidence or other structural problems
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before booking.

What we’re called out for in West Silvertown
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Most people get in touch after spotting one of these:
- Hard, crazed mastic that has stopped moving
- Brick movement joints where the sealant has split
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
In the older streets around St Barnabas' Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
What your quote should include
- What product goes in the joint
- When the joint can take water or movement
- What insurance they hold
- Whether you can choose the colour
Can I do it myself?
A careful DIYer can reseal a simple joint, 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.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
