Surface by surface
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
External mastic in Frant, done properly
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. We work on joints between brick and frames, render & cladding joints and brickwork movement joints, and people most often call us about plants rooting in failed movement joints and movement joints with cracked, split or missing sealant.
Older homes in small places like Frant 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.
All of our work is guaranteed for twelve months.

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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. Everything old must be removed first.
External mastic in Frant: local notes
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. With historic houses such as Wadhurst Castle (about 3.5 miles south-east) nearby, there’s older building stock in the area around Frant as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Letting a property close to Frant station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Frant Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Questions from Frant
Will you come out to Frant?
Yes. Frant is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Frant for external mastic?
Yes, Frant is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.
Can you reach joints on upper floors?
Each building is different. Send us photos and a rough idea of the height.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
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.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Look over the joints every year, ideally after winter
- Keep movement joints as flexible joints, not mortar
- Ask before painting over external sealant
- Point out the joints to other trades
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
Do you need external mastic in Frant?
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
People generally contact us after spotting one of these:
- Brick movement joints where the sealant has split
- Rigid filler in a joint that should flex
- Joints where the bead has come unstuck
- Leaking joints around cladding and façade panels
If you live in an older home near The Parish Church of St Alban, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How the visit works
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. The work usually takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Frant, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- 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.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in
