External mastic for homes and businesses in Broad Oak
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint does not stand out. Common call-outs are for moss and dirt in joints with no sealant left and rigid filler in a joint that should flex, on joints between brick and frames, render & cladding joints and copings & trims.
Older homes in small places like Broad Oak may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

What external mastic looks like in Broad Oak
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.
Rented homes near Winchfield station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near All Saints Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Should I point up the gap in my brickwork?
No. A mortar-filled joint can’t move, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
When will the joints need doing again?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Is there a guarantee?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Wash walls gently around the sealant
- Check external joints each spring
- Make sure movement joints aren’t pointed over
- Act on the first splits you see
Keep pressure washers away from the sealant. High-pressure water can lift the edges and let water in behind.
Act while the splits are small. At that stage it’s a simple cut out and reseal.
Signs you need external mastic in Broad Oak
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall and make things worse.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that has lost its bond to the brick or render
- Leaking joints around cladding and façade panels
- Failed seals between different materials
- Joints pointed up with cement by mistake
For site and facilities teams at buildings such as Mayhill Junior School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What we cannot put right
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Cracking across the wall rather than at a joint
- Cutting new joints into brickwork, which is building work rather than sealant work
- Loose or hollow render, which needs re-rendering
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.

Why deal with it now?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a small place like Broad Oak, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.
