Different surfaces, different methods
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 if the joint can be cleared.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
External mastic for homes and businesses in Yalding
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. We work on copings & trims, concrete & block and render & cladding joints, and common reasons people get in touch are old sealant gone brittle and cracked and moss and dirt in joints with no sealant left.
In a village or hamlet like Yalding, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours to a few days, depending on the length of joint and the access, and the area is left clean. For a village or hamlet like Yalding, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- 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
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints

Yalding: your questions answered
Do you cover Yalding for external mastic?
Yes. Our work covers London and the South East, and Yalding is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
I let a flat near Yalding station. Can you help?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Can you reach joints on upper floors?
It depends on the building. We work on joints that can be reached safely. Give us some details and we will confirm the access.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We’ll give you a better idea when we quote.
What is a movement joint?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Look over the joints every year, ideally after winter
- Act on the first splits you see
- Never let anyone fill a movement joint with mortar
- Fix overflowing gutters above sealed joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants are not designed to be painted.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
Why act early in Yalding
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Around Yalding, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

External mastic in Yalding: local notes
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.
If you live in an older home near St Peter's and St Paul's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Yalding station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

What sealant work cannot fix
We’ll always be straight with you, so here’s what sealant cannot fix:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracked brickwork or render that needs a builder or plasterer
- Movement that’s more than a sealant joint can take
