About our commercial sealant contractors in Findon

Sometimes a split bead is a symptom rather than the cause. Water at a window perimeter might be coming from the frame, the cill or the wall behind, and repeated splits in a movement joint can mean the joint is too narrow for the movement. We look before we quote and tell you plainly if sealant won’t solve it. We work on floor and threshold joints, window and door perimeters and washrooms and tea points, and the usual reasons a site gets in touch are layers of sealant, all of them failing and gaps behind commercial kitchen worktops and sinks. Most enquiries from Findon start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

A lot of what we do in Findon is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Work in smaller places such as Findon tends to come one building at a time: a pub kitchen, a hall, a small office. We’ll want a full list and photos first, so the right products come on the day and nothing waits for a second trip.

Work we carry out in West Sussex comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or send photos by email and we’ll come back to it.

Common questions from Findon clients

Is a smaller place like Findon outside your area?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Does your area include sites such as Gosling Croft Business Centre, near Findon?

Yes. Our area takes in Findon and its surroundings, with estates and business parks such as Gosling Croft Business Centre included. A few photographs and the unit address let us price the work.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Can weather delay the job?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Which sealant will you use?

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

Could the old sealant in an older building contain asbestos?

It can, on some older buildings. So we check the register first and stop work on anything suspect until it’s tested. HSE guidance on asbestos is a useful reference.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Shops, offices and hotels in and around Findon

The South East is one of the drier parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. The area within 2 miles of Findon holds several hotels. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter, and the work can be phased so the rest of the hotel keeps trading.

On a business park such as Gosling Croft Business Centre (2.5 miles south-west of Findon), sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters. A hotel such as Findon Manor Hotel (less than half a mile west of Findon) shows how much sealant a hospitality building has on show, from bathroom joints to the bar. Premises within reach of West Worthing station, 3.4 miles south of Findon, often have busy frontages where joints are seen by everyone passing.

Findon is about 3 miles north of Worthing, in West Sussex. Anywhere in BN14, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 373 places in West Sussex. There’s a separate page for Brighton, roughly 12 miles from Findon.

Work on sealant joints is covered throughout BN14, whatever the building. Among the streets we cover are High Street, Southview Road and Summerfields. Just outside Findon, we also work in High Salvington (1 mile south), Cote (2 miles south), Durrington (2 miles south), Clapham (2 miles south-west) and Patching (2 miles south-west). Bigger towns within reach include Horsham (14 miles north), Worthing (3 miles south), Bognor Regis (13 miles south-west), Burgess Hill (14 miles north-east), Littlehampton (7 miles south-west) and Shoreham-by-Sea (6 miles east).

What the job involves on each surface

Shop fronts and retail fit-outs

In retail, sealant is on show. Counters, display units, shopfront frames and floor trims all need a neat line, frequently colour-matched to the fit-out. We’ll confirm the colours available for the specified product.

Facade and cladding joints

Facade sealant failures can be hard to spot from the ground. Close-up photographs or a site visit tell us what’s needed.

Doing it in-house

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.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Findon can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. Site photographs, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  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. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

How the quote is worked out

What shapes the price:

  • Removal of failed or old sealant
  • How much there is to seal
  • How accessible the joints are
  • The site’s rules and procedures

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

What we need to price the job

However big the job, these details speed things up:

  • How the joints are reached, and at what height
  • The site address and postcode
  • Any specification or named product
  • Any dates the work must fit around

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Why act early in Findon

A cheaper quote sometimes means the old bead stays in. New sealant laid on old silicone has nothing to bond to, so it peels. Our prices always include removal of the failed bead and full joint preparation. Around Findon, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.

The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote when you are ready.

Aftercare for building managers

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • On pre-2000 buildings, share the asbestos information before work starts
  • Act on the first lifting edges rather than waiting
  • Keep a record of which joints were resealed and when
  • Ask fit-out and M&E contractors to report any sealant they disturb

Later works are the usual way new joints get damaged. When fittings are moved or cabling added, the sealant nearby is easily disturbed, and it’s easy to forget to reseal afterwards. Where work has disturbed a joint, just call the office on 01277 525 020 or use the quote form for a quote.

In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Environmental health officers look at how cleanable surfaces are, which makes sound joints worth keeping on top of.
