Commercial sealant contractors for businesses in Worthing

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Our process

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For premises in central Worthing, deliveries and parking need a bit of planning, whereas edge-of-town units normally have yard space. Let us know what’s there when you send details.

  1. We start with the evidence: photos, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

Before we start on site

  • Explain the parking and delivery arrangements
  • Tell us your opening times and when work is allowed
  • Flag any permit to work we’ll need

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Advice

How we handle commercial sealant contractors in Worthing

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and on a working site that typically surfaces as a leak, a stain or a complaint from occupiers. We’re commercial sealant applicators for FMs, managing agents, landlords and contractors looking after property in Worthing. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. We work on window and door perimeters, kitchen worktops and splashbacks and external facade joints, and what we are called in for most is external beads that have gone brittle and cracked and gaps behind commercial kitchen worktops and sinks. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Worthing is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

The most common commercial job in Worthing is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.

Around a large place like Worthing, commercial sealant work splits between town-centre premises and out-of-town parks and estates. Offices want neat internal joints and dry window perimeters, while hotels and restaurants need cleanable joints in kitchens and washrooms, and all of it can sit under one quote.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Signs you need commercial sealant contractors in Worthing

Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed will all fail early. BS 6213 gives guidance on choosing construction sealants.

Clients normally get in touch after noticing one or more of the following:

  • Earlier reseals applied straight onto the failed bead
  • Smeared sealant across finishes from a rushed job
  • Frame sealant that has cracked, shrunk or pulled away
  • Movement joints packed with grit and debris

Occupiers with premises at both Goring Business Park and Downlands Business Park could have the sealant at each handled under one quote.

How to choose a sealant contractor

Why it’s worth doing now in Worthing

Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We can help you prioritise, starting with the joints most likely to let water in. On a busy site in a large place like Worthing, a failed joint gets worse with every day of use, until a reseal turns into a repair. Acting early keeps it a sealant job.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Why appoint us

  • Constructionline member for supplier checks
  • Commercial sealant work since 2005
  • CSCS-carded applicators
  • Fixed quotes based on photographs, drawings or a visit

Questions we’re asked in Worthing

Does your area include sites such as Goring Business Park, near Worthing?

Yes. Estates, retail parks and business parks around Worthing, Goring Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Will our hotel in Worthing need to close for the work?

Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Will the building have to shut during the work?

It’s normal for us to work in occupied buildings. Only the area being sealed is closed, and the sequence is agreed in advance for as long as the cure needs.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

What the job involves on each surface

Window and door perimeters

Internally, window boards and frame edges often have decorators’ caulk or silicone that has cracked. We use a paintable product where decorating follows and a silicone where it doesn’t, in a shade that suits the frame.

Commercial kitchens and tea points

In kitchens, sealant lines at worktops, sinks and wall panels take heat, grease and daily cleaning. They’re degreased thoroughly before resealing.

After the work

A few simple habits keep the new joints working:

  • Keep abrasive pads and scrapers off resealed joints
  • Look at the sealant around anything that has been moved or replaced
  • Add sealant to the planned maintenance inspection list
  • Keep a record of which joints were resealed and when

Brief your cleaning team on the joints that have been resealed. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces; a mild cleaner is all most joints need.

Sealant rarely fails all at once across a building. The first failures are often a warning about the rest, so it makes sense to look at the wider elevation or block. We can assess the lot and suggest what to do now and later.
