Contractors’ notes for South Bersted
South Bersted is within about 1 mile of the coast. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so we check the specified product suits the exposure before the first bead. There are a good number of hotels within about 2 miles of South Bersted. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
When a school such as South Bersted CofE Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. On a campus such as University of Chichester (Bognor Campus), 0.6 miles to the south-east of South Bersted, new teaching buildings and residences are usually built and refurbished around the academic year.

About our construction mastic in South Bersted
We work to the specification and the programme rather than whatever product is to hand. If a product is named, that’s what goes in; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance. Most enquiries involve sanitary sealant damaged by following trades and frame perimeters left unsealed or poorly sealed, across floor and skirting junctions, internal decorators’ caulk and window and door perimeters. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in South Bersted it comes down to the same thing: the right product in a properly prepared joint.
Around places like South Bersted, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Why deal with it now?
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you are ready.

Maintenance after handover
For the best life from the joints:
- Get the mastic subcontractor involved early in the programme
- Ask installers to correct oversized gaps first
- Keep finished joints away from paint, plaster and scrapers
- Stick to the specified sealant rather than a generic substitute
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead, so stick to soft cloths and gentle cleaners near sealant.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
Surface by surface
Snagging before handover
Snagging is often the final mastic stage. Snags are cleared room by room, cutting out damaged joints and resealing them properly.
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. One applicator team gives the same finish everywhere.
When something else is needed
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Specifying the product where the designer hasn’t
- Glazing units that are cracked or misted
- Rework caused by others damaging completed areas
If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Questions we are asked in South Bersted
Can work at a site such as University of Chichester (Bognor Campus) fit around teaching?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you work on a hospital site such as Bognor Regis War Memorial Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Do you cover South Bersted?
Yes. South Bersted is in our area, within our coverage of Greater London, South East England and Scotland. To discuss a job, speak to us on 01277 525 020 or email us.
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 it all comes out first.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
Can you fit around our programme?
Our work is sequenced around the programme. Each plot, floor or elevation is sealed when it’s ready.

Common problems we fix in South Bersted
On construction sites, joints normally fail early because of when they were sealed, not what was used. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, and the joint has to be redone.
If one of these sounds familiar, it’s time for a closer look:
- Internal caulk splitting as the building dries out
- Mastic snags holding up handover
- Oversized or tapered gaps around new frames
- Existing joints on a refurb that need cutting out and resealing
New units and refits on sites such as Durban Road Industrial Estate (to the north of South Bersted) need their panel and perimeter joints sealed to the specification.
