External mastic in East Lavington
Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. If you’re dealing with joints where the bead has come unstuck and water getting into walls through failed joints, we can help.
Older homes in small places like East Lavington 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.
Each job carries a 12-month guarantee, large or small.

Outside joints around East Lavington
London and the South East are among 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 Bignor Roman Villa (about 2.9 miles south-east) are a reminder that the area around East Lavington has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For an older house near a landmark such as The Parish Church of St Peter, the joints between older walls, newer extensions and the roofline need a sealant that can move.

How the visit works
The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. Somewhere like East Lavington needs a little journey planning: 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.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Mention any tricky access
- Let us know about parking restrictions
- Keep children and pets away from the work area

Advice
Signs you need external mastic in East Lavington
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Most people get in touch after spotting one of these:
- Joints where the bead has come unstuck
- Water getting into walls through failed joints
- Rigid filler in a joint that should flex
- Old sealant gone brittle and cracked
For site and facilities teams at buildings such as Graffham CofE Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Aftercare tips
A little care helps the new joints last. We recommend:
- Act on the first splits you see
- Check external joints each spring
- Clear growth from the base of walls and joints
- Keep high-pressure jets off the joints
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Older cottages and farmhouses around East Lavington can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Different surfaces, different methods
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.

Do you cover smaller places like East Lavington?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is the work guaranteed?

Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
