What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Frames fitted out of tolerance
- Damage to finishes by other trades after we’ve sealed
- Defective windows, doors or glazing units (the supplier or installer’s job)
If you are not sure, just call 01277 525 020 or email drawings and photos and we will give you a straight answer.
Surfaces we seal
- Window and door perimeters
- Sanitary and kitchen joints
- Brick and block movement joints
- Floor and skirting junctions
- Internal decorators’ caulk
- Cladding and panel joints
Construction mastic in Hangleton
We work to the specification and the programme. Where the specification names a product, we use it. Backing, primer and depth follow what the sealant maker sets out, so the joints perform as the designer intended. The enquiries we see most involve bath and shower joints scraped during the final clean and a mastic package split between trades with no clear owner, on cladding and panel joints, window and door perimeters and internal decorators’ caulk. Searching for sealant specialists in Hangleton? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Around smaller places like Hangleton, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

After the work
Problems stay small when the joints are checked regularly. In particular:
- Plan external elevations with the weather in mind
- Use the product the specification names
- Keep scrapers and abrasive pads off new beads
- Ask for joint and product checks before the package is urgent
A new structure shifts as it loses construction moisture. The right product in each joint copes with that. If that happens, let us know.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks.
Site staff or a sealant specialist?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Why it’s worth doing now in Hangleton
It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites, which avoids last-minute problems. Leave it late and they turn up on the snag list. For buildings around smaller places like Hangleton, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

New build and refits around Hangleton
Hangleton is within about 2 miles of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. At about 49 miles from central London, Hangleton is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.
For contractors refurbishing units at places like Goring Business Park, 1.5 miles east of Hangleton, the mastic covers cladding panels, roller-door and window perimeters. Projects at schools like Ferring CofE Primary School work to term dates, so mastic is programmed tightly.
Hangleton is about 2 miles west of Worthing, in West Sussex. Any commercial site in Hangleton is covered, whether it’s a single job or part of a planned programme. Across West Sussex, 373 places are covered, Hangleton among them. For work in that direction, see our Brighton page (14 miles or so).

Do you need construction mastic in Hangleton?
Value-engineered products sometimes end up in the wrong joints. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
Clients normally get in touch after noticing something like this:
- Internal caulk splitting as the building dries out
- External joints sealed in damp or cold conditions that are now failing
- Failed sealant in an existing building being refurbished
- Frame gaps too wide for sealant alone
Work at a hotel such as Angmering Manor Hotel, 1.2 miles to the north-west of Hangleton, tends to be programmed around bookings, mastic included.

Common questions from Hangleton clients
Is Hangleton off your patch?
Not at all. Hangleton is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Does the sea air around Hangleton change the choice of sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.
What accreditations do you hold?
CHAS and Constructionline are both in place, and our applicators hold CSCS cards. Public liability insurance is in place.
Do you use the sealant named in the specification?
We work to the specification and the manufacturer’s installation guidance. Primers, backing and joint depth follow what the manufacturer sets out.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
What guarantee comes with a mastic package?
The work is guaranteed for 12 months on the workmanship. Protecting sealed areas from following trades helps avoid damage.
