We are a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on communal kitchens and washrooms, shopfronts below residential blocks and external wall and movement joints, and the usual reasons a site gets in touch are failed external movement joints and patchy repairs in mismatched sealant.

Blocks and managed buildings in Shoreham-by-Sea
The sea is no more than about 1 mile from Shoreham-by-Sea. On buildings near the shore, the side facing the weather normally needs its mastic renewed first; plan inspections around that. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.
Site managers at schools like Buckingham Park Primary School can fit frame mastic into the summer works. With historic buildings such as Portslade Manor (to the east of Shoreham-by-Sea) in the wider area, owners of older properties around Shoreham-by-Sea should expect mastic to need a product that suits old masonry. Older community buildings, St Mary de Haura Church among them, often have frames of mixed ages whose mastic varies.

What else we do in Shoreham-by-Sea
Maintenance after handover
Problems stay small when the joints are checked regularly. In particular:
- List the paperwork your organisation requires when you send details
- Share the asbestos register when you send details
- Make it easy for occupiers to report draughts
- Start inspections with the most exposed faces
Where a paintable product was specified, it can be painted after curing. Silicone typically can’t be painted, so keep decorators off it unless told otherwise.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and saves internal repairs.
Surface by surface
Communal areas
We keep entrances and stairs open throughout. We work in sections so access is never blocked.
Tenement and older buildings
Natural stone can be marked by the wrong sealant and we choose accordingly.
Work for main contractors and building owners
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Masonry that has broken away beside the joint
- Glazing that needs replacing
- Roof leaks, gutters or failed flashings that aren’t sealant joints
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly.
Surfaces we seal
- Balcony and threshold joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- External wall and movement joints
- Window and door perimeters on blocks
- Communal entrances and stairwells

Yes, sites like Dolphin Industrial Estate are within our area, along with the rest of Shoreham-by-Sea. To start, just phone 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Does a coastal location like Shoreham-by-Sea affect which sealant is used?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
