- Damp patches traced to an open external joint
What happens if it’s left?
Resealing a run of joints in one go is normally better than patching one at a time. Joints of the same age tend to fail together. In a small place like Lidsey, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

How we handle external mastic in Lidsey
External mastic is a job where short cuts show quickly. 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, brickwork movement joints and render & cladding joints, and the jobs we see most are leaking joints around cladding and façade panels and rigid filler in a joint that should flex.
In a village or hamlet like Lidsey, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

What the job involves on each surface
Cladding and façade panels
If the façade has a specified sealant, that’s what we use, or one the system allows. Tell us what the building has when you get in touch.
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Movement that’s more than a sealant joint can take
- Adding movement joints to masonry that has none
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.
What we seal
- Joints between brick and frames
- Façade panels
- Render & cladding joints
- Concrete & block
- Copings & trims
- Brickwork movement joints
Lidsey buildings and the weather
Lidsey is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
Schools such as Aldingbourne Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as The Parish Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain.

What we do, step by step
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Lidsey, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit

Signs you need external mastic in Lidsey
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
If you can see any of these, it’s time to have the joints looked at:
- Water getting into walls through failed joints
- Joints where the bead has come unstuck
- Brick movement joints where the sealant has split
- Leaking joints around cladding and façade panels
For landlords with property near Barnham station, outside joints that have cracked can let damp into a rental, so check them between lets.

What else we do in Lidsey
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
FAQs for Lidsey
Is external mastic in a coastal place like Lidsey any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Will you come out to Lidsey?
Yes. Lidsey 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.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Are you fully insured?
Yes. Full insurance covers our work.
Can you match the colour of my brickwork?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin from the range available.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Leave the joints unpainted unless we’ve said otherwise
- Get split or bare joints resealed while the damage is small
- Show decorators and builders where the movement joints are
- Keep high-pressure jets off the joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
