Professional external mastic in and around West Chiltington Common, with old sealant always removed completely and a one-year guarantee.
- Weeds or debris growing in open joints
- Water getting into walls through failed joints
- Leaking joints around cladding and façade panels
When something else is needed
Sealant isn’t the answer to every problem, and we will tell you before we start. Sealant won’t put right:
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer
- Rising or penetrating damp from elsewhere in the wall
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
What we seal
- Joints between brick and frames
- Brickwork movement joints
- Render & cladding joints
- Concrete & block
- Copings & trims
- Façade panels
External mastic for homes and businesses in West Chiltington Common
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render. We work on façade panels, render & cladding joints and joints between brick and frames, and the jobs we see most are weeds or debris growing in open joints and movement joints filled with mortar instead of sealant.
In and around West Chiltington Common, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

Do you need external mastic in West Chiltington Common?
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Keep an eye out for any of the following:
- Plants rooting in failed movement joints
- Movement joints filled with mortar instead of sealant
- Leaking joints around cladding and façade panels
- Failed seals between different materials
Rented homes near Pulborough station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Make sure movement joints aren’t pointed over
- Clear growth from the base of walls and joints
- Act on the first splits you see
- Keep water from gutters off the wall
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.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

- 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.
- 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.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints
- Let us know about parking restrictions
