Advice
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Leave it or put it right?
Water gets in through a failed movement joint, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Around Angmering-on-Sea, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Keep soil, plants and ivy away from the joints
- Never let anyone fill a movement joint with mortar
- Show decorators and builders where the movement joints are
- Fix overflowing gutters above sealed joints
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.
Do you need external mastic in Angmering-on-Sea?
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.
These are the problems we are asked about most:
- Weeds or debris growing in open joints
- Panel joints letting water in
- Brick movement joints where the sealant has split
- Joints pointed up with cement by mistake
Letting a property close to Angmering station? Then split movement joints are easy to miss on a rental until damp shows inside.

Angmering-on-Sea buildings and the weather
Angmering-on-Sea 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 is hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Ecclesden Manor (about 1.7 miles north) are a reminder that the area around Angmering-on-Sea has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Schools such as East Preston Infant School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near The Parish Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Your questions about external mastic in Angmering-on-Sea
Is external mastic in a coastal place like Angmering-on-Sea any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Is Angmering-on-Sea within the area you cover?
Yes, Angmering-on-Sea is covered. 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.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
How long does external mastic take?
A typical job takes a few hours to a few days, depending on the length of joint and the access, including preparation and clearing up. Your quote will say how long we expect yours to take.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges.
