Construction mastic in Adur
Getting a subcontractor through site induction should be simple. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we’re fully insured. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. If you have inconsistent sealant finishes from plot to plot and cracks opening in caulked internal joints, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Adur it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Conversions of older rural buildings near smaller places such as Adur bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Questions we are asked in Adur
Is a hospital such as Southlands Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Do you cover business parks and estates near Adur, such as Dolphin Industrial Estate?
Yes, sites like Dolphin Industrial Estate are within our area, along with the rest of Adur. Send details of the unit and the work through our quote form for a quick quote.
Is colour matching possible?
It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Can you seal external joints in wet or cold weather?
External mastic depends on conditions: the joint needs to be dry and within the product’s temperature range. We plan external elevations with that in mind.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can you fit around our programme?
The programme sets the job. Tell us the sequence and we will plan applicators around it, sealing as areas become ready.

Contractors’ notes for Adur
Adur sits close to the coast, within about 2 miles. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so joint design, primers and product choice deserve extra care. Adur is about 45 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.
Extensions at sites like Southlands Hospital, 1.7 miles south-east of Adur, normally sit beside working departments, and the mastic follows strict access rules. Older buildings in the area around Adur, such as Portslade Manor (3.2 miles east of Adur), need care when sealed: the product has to suit soft or historic materials.
Adur is about 1 mile north-west of Shoreham-by-Sea, in West Sussex. We cover commercial sites throughout Adur, whether it’s a single job or part of a planned programme. We work across 373 places in West Sussex. For work in that direction, see our Brighton page (7 miles or so).
We take on mastic packages across the BN43 and BN15 postcode area, whatever the building. Streets here include Steyning Road, Coombes Road and Mill Hill, and sites on any of them can send details for a fixed quote. Nearby places we also cover include Old Shoreham (1 mile south), Shoreham-by-Sea (1 mile south-east), Castle Town (2 miles north), Kingston by Sea (2 miles east) and Southwick (3 miles south-east). A short drive away, we cover Horsham (15 miles north), Worthing (5 miles south-west), Haywards Heath (13 miles north-east), Burgess Hill (10 miles north-east), Littlehampton (11 miles west) and Rustington (10 miles west).
Local landmarks in Adur
We work on buildings around Sussex Pad pub. The nearest railway station is Shoreham-By-Sea station, about 1.5 miles south-east of the centre. A little further out are Steyning Museum (2.9 miles north-west) and Old Castle (4.9 miles south-west). Not far away are Lancing Ring and Mill Hill.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Allow flexibility for external sealing in damp or cold weather
- Put any product change through the designer first
- Keep product details for future maintenance
- Share drawings and the specification as soon as possible
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement. If that happens, let us know.
One unsealed frame can let water into finished internal areas. That typically means redoing finishes in a completed area. Checking perimeters before internal finishes go on avoids it.
What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Whether the work must be split into stages
- Distance, for remote addresses
- Access and working height
- Site requirements such as inductions and permits
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Sending details for a quote
Whether it’s one area or a whole building, these details speed things up:
- Clear photographs of the problem areas
- Where the site is, with the postcode
- Specification clauses that apply
- What the building is and how it’s used
For a fixed quote, call 01277 525 020 or email drawings and photos with the site address and an outline of the work. You can also send details through our quote form.
Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work normally takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. Jobs in and around smaller places like Adur are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
What we need from you
- Tell us your opening times and when work is allowed
- Point out parking and an unloading spot
- Send asbestos survey details if the building is pre-2000

When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
How the job changes by surface
Internal decorators’ caulk
Caulk is easy to apply badly. Done properly, it saves decorators time and gives a clean line and reduces snags.
Window and door perimeters
Internal perimeters are usually sealed with a paintable product where decorating follows. We follow what’s specified.
When to call us in Adur
On construction sites, joints normally fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, so they end up back on the snag list.
These are often picked up first by site or facilities staff:
- A mastic package split between trades with no clear owner
- Snag items on joints that need redoing before handover
- Missed perimeter joints on a new elevation
- Perimeter gaps outside the sealant’s range
For contractors at a school such as The Sir Robert Woodard Academy, sealing has to be finished before term starts.
