How we handle external mastic in Littlehampton
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what access is needed. We work on concrete & block, joints between brick and frames and copings & trims, and the jobs we see most are weathered mastic that no longer stretches and cracked joints where brick meets render or frames.
Plenty of homes in a town like Littlehampton have been extended, and the line where an extension meets the original house is a common leak point. Sealing it properly means the right joint depth and a flexible sealant, not a quick bead.
Your job is guaranteed for a year, as with all our work.

Different surfaces, different methods
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Do you need external mastic in Littlehampton?
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
Look out for these signs:
- Joints where the bead has come unstuck
- Failed sealant between panels on a façade
- Weeds or debris growing in open joints
- Water getting into walls through failed joints
Letting a property close to Littlehampton station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Littlehampton questions
Do you work for landlords with property near Littlehampton station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
Is external mastic in a coastal place like Littlehampton any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
How much does external mastic cost in Littlehampton?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or drop us an email.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
What’s an expansion joint in brickwork?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Leave it or put it right?
Sealing over the top of old mastic does not hold for long. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. Gaps in sealant and mould in the bead never get better on their own, and in a busy home in Littlehampton they get worse with every use. Replacing the sealant now is the simplest fix.
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What you get with us
- Full insurance on every job
- Anti-fungal sanitary silicone in wet areas
- We leave the area clean and tidy
- White, clear, grey or another colour, product permitting

What external mastic looks like in Littlehampton
Littlehampton is within about 1 mile of 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. With historic houses such as Ecclesden Manor (about 2.9 miles north-east) nearby, there’s older building stock in the area around Littlehampton as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around The Parish Church of St Mary the Virgin, the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like The Littlehampton Academy? Then its movement joints, gutters and trims need looking after like any other building’s.
