What external mastic looks like in Norton
Norton is within about 2 miles of 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Andrew, the joints between older walls, newer extensions and the roofline need a sealant that can move. For site and facilities teams at buildings such as UTC@Harbourside, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

External mastic in Norton
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. We work on copings & trims, façade panels and joints between brick and frames, and the jobs we see most are leaking joints around cladding and façade panels and rain getting behind render or cladding at a joint.
Older homes in small places like Norton may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Norton questions
Is Norton within the area you cover?
Yes, Norton is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Does the coastal weather in Norton affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
What does external mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.

How it works
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. Somewhere as small as Norton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises

Quotes for external mastic in Norton
We quote each job individually. This is what makes a difference:
- The size of the job
- Any working-time requirements on site
- Access and height
- Mould in or behind the old joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
When you contact us, these details help:
- The address or postcode of the job
- What’s wrong with the joints now
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
What happens if it’s left?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Older cottages and farmhouses around Norton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.

Common problems we fix in Norton
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.
People normally contact us when they notice one of these:
- Failed sealant between panels on a façade
- Rain getting behind render or cladding at a joint
- Brick movement joints where the sealant has split
- Rigid filler in a joint that should flex
If you let a flat or house near Bishopstone (Sussex) station, outside joints that have cracked can let damp into a rental, so check them between lets.

Surface by surface
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod.
