Frontages, fit-outs and joints in Shoreham-by-Sea

Shoreham-by-Sea lies within about 1 mile of the sea. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. Sea-facing elevations are usually where failed joints show first. Shoreham-by-Sea has at least three named business or industrial parks inside a 3-mile radius. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints, often in a colour the occupier specifies.

Occupiers with premises at both Dolphin Industrial Estate and Grange Industrial Estate could have the sealant at each handled under one quote. If you run a unit on an estate such as Dolphin Industrial Estate (0.6 miles east of Shoreham-by-Sea), the trade counter, offices and staff facilities have joints to look after as well as the warehouse. Premises within reach of Shoreham-By-Sea station, under half a mile to the south-west of Shoreham-by-Sea, often have busy frontages where joints are seen by everyone passing.

About our commercial sealant contractors in Shoreham-by-Sea

On a commercial site, sealant turns up in more places than people expect: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Outside, it closes facade joints, frame perimeters and movement joints against the weather. We deal with internal and external sealant joints alike, matching the sealant to the location instead of using one product throughout. We work on window and door perimeters, floor and threshold joints and external facade joints, and what we’re called in for most is black mould through washroom sealant that won’t clean off and greasy, split joints in a kitchen or tea point. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Shoreham-by-Sea, that means joint design, primers and backing rod as standard.

Multi-site clients with buildings in and around Shoreham-by-Sea can put several sites on one programme, with one quote format and one point of contact.

Smaller commercial landlords and businesses in a town like Shoreham-by-Sea often have a handful of sealant jobs that can go on one visit: say a shopfront perimeter, a tea point, a washroom and some frames. A single fixed quote covers everything on the list.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

On site: what to expect

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Parking and loading for town-centre jobs in Shoreham-by-Sea are worth mentioning when you send details. On estates and business parks it’s normally simpler.

  1. We start with the evidence: photos, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. Completed areas are signed off with you under our 12-month guarantee.

Getting the site ready

  • Let building users know which areas are affected
  • Send any specification or drawings in advance
  • Send your site hours and access windows

FAQs: Shoreham-by-Sea

Our building in Shoreham-by-Sea is near the coast: does that change the sealant?

It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.

Will you take on work at estates like Dolphin Industrial Estate, close to Shoreham-by-Sea?

Yes. Our area takes in Shoreham-by-Sea and its surroundings, with estates and business parks such as Dolphin Industrial Estate included. To start, just phone 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Is your work guaranteed?

It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.

Is it OK to apply fresh sealant over existing beads?

Removal of the failed sealant is always part of the job. New sealant can’t grip the old bead, so laying over it never lasts.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Can you handle sealant work across several sites?

Yes. Send a list of addresses and what’s needed at each, and fixed prices follow, with a suggested sequence.

Do you work in Shoreham-by-Sea?

Yes. Sites across Shoreham-by-Sea are covered.

When it isn’t the sealant

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Water from a services leak rather than a joint
  • Cracking that needs a structural engineer to look at it
  • Roof leaks that only look like a joint problem

If in doubt, ring 01277 525 020 or email us and we will say what we think.

What we seal

  • Washrooms and tea points
  • Kitchen worktops and splashbacks
  • External facade joints
  • Floor and threshold joints
  • Window and door perimeters
  • Movement joints in walls and floors

Doing it in-house

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with 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.

What the job involves on each surface

Fire-rated seals where specified

Fire-rated sealant is only one type of fire-stopping product. Other products, such as collars, wraps and batts, are specified for different services.

Window and door perimeters

Where frames meet the surrounding wall, sealant is the weather line. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.

Why act early in Shoreham-by-Sea

A cheaper quote sometimes means the old bead stays in. Sealing over looks tidy at handover, then lifts once the joint starts moving. Our prices always include removal of the failed bead and full joint preparation. For businesses and landlords in Shoreham-by-Sea, a tidy, sound joint also matters for appearance. Fresh sealant makes a building look maintained.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
