Facade sealing in South Bersted

We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause, but not always. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. If you have leaks at window and door perimeters and staining on stone next to old sealant, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, the work in South Bersted is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a contractor on a smaller site near South Bersted, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.

A 12-month guarantee applies to all our work in West Sussex. If an installation problem shows up, give us a call on 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

Why it’s worth doing now in South Bersted

Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice, saving a second set-up. For buildings in places like South Bersted, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

A quote for facade joints depends on how many there are, their condition and the access. Call for a quote.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Facade sealing around South Bersted: how the place shapes the job

With the shore within about 1 mile, South Bersted counts as a coastal location. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. Plenty of hotels sit less than 2 miles from South Bersted. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

Hotel extensions and refits, at places such as The Gables Hotel, 0.6 miles south of South Bersted, typically run between busy periods, so the sealing is squeezed into short windows. School extensions, at buildings such as South Bersted CofE Primary School, typically run to the summer holidays, mastic included.

South Bersted is about 1 mile north-east of Bognor Regis, in West Sussex. Businesses, contractors and managing agents in South Bersted can call on us for facade joints, as part of our coverage of West Sussex. We work across 373 places in West Sussex, large and small. For work in that direction, see our Portsmouth page, about 18 miles away.

Common questions from South Bersted clients

Can you work on a hospital site such as Bognor Regis War Memorial Hospital?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Our building in South Bersted is near the coast: does that change the sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

What type of sealant goes on window perimeters?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we will send them with the quote.

Should we check old sealant for asbestos?

In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.

How long does a job like this take?

That varies with the scale of the job, though a typical visit usually takes a day or two for a few elevations, and longer where access has to be moved around the building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Can you send site paperwork?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Common problems we fix in South Bersted

Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back.

Site and facilities staff are often the first to spot these:

  • Discoloured or dirty facade joints
  • Old perimeter mastic that has dried out
  • Cold air coming in at window perimeters
  • Cladding panel joints that have opened up

University estates such as University of Chichester (Bognor Campus), 0.6 miles to the south-east of South Bersted, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Before you book anyone

  • How the existing material will be dealt with
  • How they handle RAMS and site documents
  • How joint depth will be controlled
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

Surface by surface

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. We clean back to sound material and flag edges that need repair.

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. We seal those perimeter joints, not the framing or glazing itself.

When to bring in a specialist

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

How a job runs

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. Several jobs near South Bersted can be grouped on one trip. Mention the building’s opening times and we will work within them.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Let building users know which areas are affected
  • For older buildings, check the asbestos register before work
  • Make sure the joints can be reached
