External mastic in Broadland Row, done properly
For buildings in Broadland Row, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We work on copings & trims, joints between brick and frames and brickwork movement joints, and people most often call us about rain getting behind render or cladding at a joint and rigid filler in a joint that should flex.
Around Broadland Row, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
All our work is covered by a 12-month guarantee, wherever you are in East Sussex.

What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Render that’s blown, hollow or coming away
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracking across the wall rather than at a joint
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.

What affects the cost of external mastic
The quote reflects the job in front of us. We look at:
- How many rooms, windows or areas are involved
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- The type of sealant required
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Questions from Broadland Row
I let a flat near Doleham station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Do you cover smaller places like Broadland Row?
Yes, Broadland Row is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.
What should I tell you?
Tell us what needs doing and where, with photos by email if possible. We will ask anything else we need to know.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
What’s an expansion joint in brickwork?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly.
Different surfaces, different methods
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant.
Why deal with it now?
Resealing a run of joints in one go is normally better than patching one at a time. They’ve weathered the same way and it means sorting access once. Around Broadland Row, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.
Why us?
- White, clear, grey or coloured to suit, where the product allows
- Sanitary silicone with an anti-fungal additive in wet areas
- Tidy, careful work
- We never seal over old sealant

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Tell anyone working on the walls about the movement joints
- Leave the joints unpainted unless we have said otherwise
- Check external joints each spring
- Get split or bare joints resealed while the damage is small
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The process
Before we leave, we go over the finished joints with you. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Somewhere as small as Broadland Row, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky

Broadland Row buildings and the weather
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Great Dixter (about 4 miles north-west) are a reminder that the area around Broadland Row has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For an older house near a landmark such as The Parish Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you let a flat or house near Doleham station, split movement joints are easy to miss on a rental until damp shows inside.
