External & façade joints in Church Norton, West Sussex
Professional external mastic in and around Church Norton, with every bit of old sealant taken out first.
- Gaps where render, brick and frames meet
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Adding movement joints to masonry that has none
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracking across the wall rather than at a joint
If in doubt, phone 0345 464 0079 or email us and we will say what we think before booking.
Joints and surfaces we work on

- Façade panels
- Render & cladding joints

External mastic in Church Norton, done properly
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. Typical jobs include weeds or debris growing in open joints and water getting into walls through failed joints, across joints between brick and frames, concrete & block and façade panels.
Somewhere as small as Church Norton, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on the building, depending on how much there is to do. Somewhere as small as Church Norton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property
- Tell us about any water getting in

What affects the cost of external mastic
You’ll get a clear quote before any work starts. It takes into account:
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- The amount of work
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Where the property is
- Photos by email, if that is easy
- Access, such as stairs, a lift or height
- The problem you’ve noticed
We don’t publish a price list. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Ask before painting over external sealant
- Check external joints each spring
- Avoid pressure-washing directly into sealant joints
- Keep movement joints as flexible joints, not mortar
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
Church Norton questions
Is external mastic in a coastal place like Church Norton any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
I let a flat near Bognor Regis station. Can you help?
Yes. We work for landlords and agents as well as homeowners. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher ones, send details and we’ll confirm the access.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
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. The sealant is matched to both sides.
What we are called out for in Church Norton
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall.
Common reasons people contact us include:
- Joints where the bead has come unstuck
- Joints pointed up with cement by mistake
- Movement joints with cracked, split or missing sealant
- Old sealant gone brittle and cracked
For an older house near a landmark such as St Wilfrid's Chapel, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Questions to ask before you book
- How the joint is cleaned and prepared
- How long the guarantee is
- Whether the sealant suits the joint
- Whether VAT is included
Why deal with it now?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together and it means sorting access once. Around Church Norton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

Church Norton buildings and the weather
Church Norton is within about 1 mile 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as The Academy, its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Bognor Regis station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
