External mastic in Allhallows-on-Sea: local notes
Allhallows-on-Sea is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Chalkwell station, outside joints that have cracked can let damp into a rental, so check them between lets. In the older streets around Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant.

About our external mastic in Allhallows-on-Sea
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where mortar or filler would crack. If you have brick movement joints where the sealant has split and old sealant gone brittle and cracked, we can put it right, on joints between brick and frames, brickwork movement joints and concrete & block alike.
External sealant needs dry, clean surfaces, so work around Allhallows-on-Sea is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
You are covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or email us.

Aftercare tips
To keep the joints looking good and working properly:
- Do not let climbing plants root in the sealant
- Show decorators and builders where the movement joints are
- Check the sealant is paintable before painting near it
- Act on the first splits you see
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
What the job involves on each surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. The sealant is chosen with that in mind.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly if the joint can be cleared.
What we cannot put right
In fairness, some problems need a different trade:
- Rising or penetrating damp from elsewhere in the wall
- Cracked brickwork or render that needs a builder or plasterer
- Adding movement joints to masonry that has none
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

Allhallows-on-Sea questions
Do you work for landlords with property near Chalkwell station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Do you cover smaller places like Allhallows-on-Sea?
Yes, Allhallows-on-Sea is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work at height?
It depends on the building. We work on joints that can be reached safely. Give us some details and we will confirm the access.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides with primer where required.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do you need external mastic in Allhallows-on-Sea?
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
The problems people usually mention when they call are:
- Leaking joints around cladding and façade panels
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
- Joints with sealant missing in places
For site and facilities teams at buildings such as Allhallows Primary Academy, its movement joints, gutters and trims need looking after like any other building’s.

If the job is outside, mention outbuildings, exposed walls and how to reach them.

- Old sealant and any debris are cut and raked out.
- 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.
