How we handle facade sealing in Worthing

Managing agents and owners in Worthing ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. If you have weathered joints at frame-to-structure perimeters and unsightly perimeter sealant on a visible elevation, we can help, on shopfront frames, cladding panel joints and window and door perimeters alike. Whoever orders the work in Worthing, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

On larger schemes in and around Worthing, mastic is often programmed plot by plot or floor by floor. CSCS-carded applicators work to the site’s rules and the specification, and any snags are cleared before handover.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What the job involves on each surface

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed.

Brick and stone facades

Joints in natural stone need care to avoid staining. The specified stone-compatible sealant is what we use, with masked edges for a clean line.

How a job runs

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building, and we clear our waste as we work. For premises in central Worthing, deliveries and parking need a bit of planning, while out-of-town estates usually have yards and car parks. Either way, tell us what’s available.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Getting the site ready

  • Warn occupants and staff about the work
  • Agree which areas must stay open
  • Tell us what induction or permit system the site runs

Advice

Contractors’ notes for Worthing

With the shore within about 2 miles, Worthing counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care. Worthing lies roughly 48 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.

For contractors at a school such as Durrington High School, sealing has to be finished before term starts. Projects at colleges like Worthing College, 1 mile north-east of Worthing, tend to run to term dates, so the mastic is planned tightly. Hotel extensions and refits, at places such as The Railway Hotel, 1.1 miles east of Worthing, normally run between busy periods, so the sealing is squeezed into short windows.

Worthing is in West Sussex. We cover commercial sites throughout Worthing, for single jobs and planned programmes alike. Worthing is one of 373 places we cover in West Sussex for facade joints. Sites around Brighton have their own page, about 12 miles away.

Business premises anywhere in BN13, BN11, BN14 and BN12 are within our area for facade joints. For a building on Church Road, Market Place and High Street or nearby, send details and we’ll quote for facade joints. Worthing sits on or close to the A24 and A27, which helps when planning parking and deliveries for the job. Sites close to Worthing are covered too, including Salvington (1 mile north), Offington (1 mile north-east), Broadwater (1 mile east), Findon Valley (2 miles north) and East Worthing (2 miles east). Further afield, our area takes in Bognor Regis (13 miles west), Burgess Hill (15 miles north-east), Littlehampton (6 miles west), Shoreham-by-Sea (6 miles east), Lancing (3 miles east) and Rustington (5 miles west). Among the larger centres in West Sussex is Worthing, and its commercial and public buildings are all within our area.

How the quote is worked out

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Which sealant the job calls for
  • Travel to remote or island sites
  • How much there is to seal
  • How accessible the joints are

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Before you send an enquiry

There’s no need for a formal survey. These details are enough to start:

  • Approximate linear metres or a joint schedule
  • Photos of the joints, close up and from further back
  • The type of building and who uses it
  • When you need the work done

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to phone 01277 525 020 or email the details over with what you know.

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Providing access systems for the work
  • Movement beyond what any sealant can handle
  • Render or concrete edges that have broken away

If in doubt, call 01277 525 020 or email us and we will say what we think before you book.

Joints and surfaces we work on

  • Cladding panel joints
  • Perimeter joints where frames meet the structure
  • Stone and brick facade joints
  • Shopfront frames
  • Window and door perimeters
  • Coping and flashing joints

For managing agents and facilities managers

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Questions about Worthing

Can you work around term dates at a campus such as Worthing College?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Is a hospital such as Worthing Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Do you install glazing systems?

No. A glazing contractor handles that. What we seal are the joints around frames and panels across the facade.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you use silicone for external joints?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, as the specification or substrate requires.

Will you check whether the sealant is causing the leak?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Is it okay to overlay old mastic?

No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
