How we handle external mastic in Rustington
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. We work on copings & trims, brickwork movement joints and façade panels, and people most often call us about brick movement joints where the sealant has split and moss and dirt in joints with no sealant left.
Houses in smaller places like Rustington can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are usually the first to go.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Do you need external mastic in Rustington?
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
The problems people usually mention when they call include:
- Water getting into walls through failed joints
- Cracked joints where brick meets render or frames
- Panel joints letting water in
- Movement joints filled with mortar instead of sealant
If you look after a building such as Rustington Community Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What happens on the day
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. A visit to Rustington is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Advice
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Honest limits
To be straight with you, some problems need a different trade:
- Subsidence or other structural problems
- Cracked brickwork or render that needs a builder or plasterer
- Failed render or damaged cladding panels
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
Joints and surfaces we work on

Why act early in Rustington
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together, and access only has to be arranged once. Around Rustington, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What you get with us
- White, clear, grey or another colour, product permitting
- You choose the colour before work begins
- Any old sealant cut out fully, not covered over
- We leave the area clean and tidy

How the job changes by surface
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
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.
Rustington questions
Does living near the coast affect external mastic in Rustington?
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 generally the first to need attention.
Do you cover smaller places like Rustington?
Yes, Rustington is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
How much does external mastic cost in Rustington?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or send us an email with a short description of the job.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Walls and rooflines in Rustington
Rustington 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’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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near The Parish Church of St Peter and St Paul, an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Angmering station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
