External mastic in Layer Marney, done properly
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We work on copings & trims, brickwork movement joints and joints between brick and frames, and the jobs we see most are movement joints with cracked, split or missing sealant and moss and dirt in joints with no sealant left.
Older homes in small places like Layer Marney may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

What we’re called out for in Layer Marney
If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall and make things worse.
Keep an eye out for these signs:
- Joints pointed up with cement by mistake
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
- Weeds or debris growing in open joints
Managing a site like Thurstable School? Then its movement joints, gutters and trims need looking after like any other building’s.

How long does external mastic take?
A typical job takes a few hours for a handful of joints, longer for a whole elevation, including the preparation. Your quote will say how long we expect yours to take.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or drop us an email.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Can you reach joints on upper floors?
It depends on the building. Tell us the height, the number of joints and what’s below them, and we will confirm what access is needed.

What else we do in Layer Marney
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Layer Marney 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.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in

Advice
Walls and rooflines in Layer Marney
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Layer Marney Tower (about 0.4 miles south) are a reminder that the area around Layer Marney 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.
Letting a property close to Marks Tey station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as Church of St Mary the Virgin, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Check the sealant is paintable before painting near it
- Make sure movement joints aren’t pointed over
- Keep soil, plants and ivy away from the joints
- Point out the joints to other trades
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Around Layer Marney, 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 reflects the work involved, not guesswork. That’s why we ask about the job first.
