About our external mastic in Lyminge
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you’re dealing with rain getting behind render or cladding at a joint and movement joints filled with mortar instead of sealant, we can help, on concrete & block, brickwork movement joints and copings & trims alike.
Somewhere as small as Lyminge, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Your job is guaranteed for a year, as with all our work.

What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Movement that is more than a sealant joint can take
- Cracks in the bricks or render themselves, away from the joints
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
Where we work in Lyminge

- Joints between brick and frames
- Concrete & block
- Façade panels
- Brickwork movement joints
Leave it or put it right?
Resealing a run of joints in one go is normally better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. In a small place like Lyminge, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Surface by surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. We choose the product to suit.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, 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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

When to call us in Lyminge
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
It’s worth asking for a quote if you see:
- Damp patches traced to an open external joint
- Movement joints with cracked, split or missing sealant
- Rigid filler in a joint that should flex
- Leaking joints around cladding and façade panels
Acrise Place, about 2.1 miles east, is one of the historic houses in the wider area around Lyminge.

FAQs for Lyminge
Is Lyminge in your area for external mastic?
Yes, Lyminge is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
I let a flat near Sandling station. Can you help?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we will confirm what’s needed.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
What happens on the day
The work is kept neat and contained to the joints we are treating. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. For a village or hamlet like Lyminge, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks

External mastic in Lyminge: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Acrise Place (about 2.1 miles east) are a reminder that the area around Lyminge 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.
Schools such as Lyminge Church of England Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Sandling station? Then split movement joints are easy to miss on a rental until damp shows inside.
