Mastic sealing in Crossbush, done properly
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. We work on external wall and movement joints, balcony and threshold joints and window and door perimeters on blocks, and the failures we’re asked to look at most are patchy repairs in mismatched sealant and complaints coming in block by block. A single leaking joint is often how a building in Crossbush first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For buildings around smaller places like Crossbush, we group work so one trip covers it. Photos of each elevation help us quote accurately.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

For owners and agents in Crossbush
Crossbush lies within about 3 miles of the sea. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints. Rainfall across the South East, Crossbush included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Historic properties like Ecclesden Manor (3 miles east of Crossbush) show the age of some local stock, where frame mastic must suit soft brick or stone. Schools and community buildings such as The Littlehampton Academy need frame and external mastic kept sound like any building. For agents with blocks near Arundel station, which lies north-west of Crossbush, a block-wide mastic programme deals with frames, balconies and entrances in one go.
Crossbush is about 2 miles north of Littlehampton, in West Sussex. Commercial clients in Crossbush can call on us for mastic joints, as part of our coverage of West Sussex. We work across 373 places in West Sussex. For work in that direction, see our Brighton page, about 18 miles away.

When it isn’t the sealant

- Asbestos-containing sealant, which we don’t remove
- Misted or failed double-glazed units
If you’re not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. If others near Crossbush need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.

Why act early in Crossbush
Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work and less choice about when. Converted and older buildings near places like Crossbush tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
A quote for mastic joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.
What you get with us

Site staff or a sealant 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.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Common questions from Crossbush clients
Can being near the sea in Crossbush affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Can you quote for a block close to Arundel station?
Yes. Blocks of any size are within what we do. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Do you work for managing agents and housing associations?
Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
Do you work in Crossbush?
Yes. Crossbush falls within our area, and the simplest way to start is to ring 01277 525 020 or email drawings and photos.
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Look at the sunniest and most exposed elevations first
- Include mastic in your cyclical inspections
- Check the asbestos register before any old mastic is disturbed
- Group repairs into a planned programme
Log the date and extent of the resealing for each block. It helps plan the next round and gives you a history.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
