Poling External Mastic
Sealing brickwork movement joints, render, cladding and façade joints in Poling, with a 12-month guarantee on every job. Ask us for a quote.
- Damp patches traced to an open external joint
- Joints with sealant missing in places
- Sealant that has lost its bond to the brick or render
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Cracking across the wall rather than at a joint
- Loose or hollow render, which needs re-rendering
- Walls that need new movement joints cut into them
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before you book.
Surfaces we seal
- Joints between brick and frames
- Copings & trims
- Façade panels
- Render & cladding joints
- Brickwork movement joints
- Concrete & block
External mastic in Poling, done properly
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. Typical jobs include failed sealant between panels on a façade and rain getting behind render or cladding at a joint, across façade panels, joints between brick and frames and render & cladding joints.
Somewhere as small as Poling, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Questions from Poling
Will you come out to Poling?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does the coastal weather in Poling affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
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 ones, send details and we’ll confirm the access.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Have failed joints looked at early
- Show decorators and builders where the movement joints are
- Ask before painting over external sealant
- Check external joints each spring
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Common problems we fix in Poling
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
People usually contact us when they notice one of these:
- Water getting into walls through failed joints
- Old sealant gone brittle and cracked
- Joints where the bead has come unstuck
- Moss and dirt in joints with no sealant left
If you live in an older home near The Parish Church of St Nicholas, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Walls and rooflines in Poling
Poling is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Ecclesden Manor (about 2 miles east) nearby, there’s older building stock in the area around Poling as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For site and facilities teams at buildings such as The Littlehampton Academy, larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Arundel station, outside joints that have cracked can let damp into a rental, so check them between lets.

How the visit works
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. It generally takes anything from a few hours to several days, depending on the building. In a small place like Poling, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
