Facade sealing for commercial buildings in Shoreham-by-Sea

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range, and cold, damp starts can delay work. We plan for that and keep you updated. Site teams most often ask us about perimeter joints where frames meet the structure and failed sealant on precast panel joints, on stone and brick facade joints, window and door perimeters and coping and flashing joints. One point of contact handles commercial sealant work in Shoreham-by-Sea from the first photographs to the final walk-round, for single jobs and planned programmes alike.

For contractors on site in a town like Shoreham-by-Sea, the mastic has to fit the programme: perimeters sealed before scaffold is struck, internal sealant after decoration, snags before handover. Tell us the programme and we’ll quote to it.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

New build and refits around Shoreham-by-Sea

Shoreham-by-Sea sits close to the coast, within about 1 mile. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Shoreham-by-Sea lies roughly 46 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.

When a school such as Buckingham Park Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Historic houses such as Portslade Manor (to the east of Shoreham-by-Sea) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Shoreham-by-Sea is about 4 miles west of Brighton and Hove, in West Sussex. We cover commercial sites throughout Shoreham-by-Sea, for single jobs and planned programmes alike. Across West Sussex, 373 places are covered, including Shoreham-by-Sea. There’s a separate page for Brighton, roughly 6 miles from Shoreham-by-Sea.

Common problems we fix in Shoreham-by-Sea

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.

Any of the following is a good reason to get the joints checked over:

  • Air leaks through failed facade joints
  • Weathered joints at frame-to-structure perimeters
  • Leaks at window and door perimeters
  • Hard, chalky sealant that no longer flexes

Units on estates such as Dolphin Industrial Estate, 0.6 miles east of Shoreham-by-Sea, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Questions to ask before you book

  • Whether their applicators hold CSCS cards
  • What site paperwork they can supply
  • Do they follow the manufacturer’s priming guidance?
  • What level of public liability insurance do they hold?

Our contractor checklist

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Replacing glass or failed glazing units
  • Cracked or spalling substrates that need repair before sealing
  • Water getting in through cracked render or porous masonry

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

Joints and surfaces we work on

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

Common questions from Shoreham-by-Sea clients

Does the sea air around Shoreham-by-Sea change the choice of sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Would you work within a site like Southlands Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

Can you work while the building is occupied?

Typically, yes. Phased work can be planned so areas stay in use.

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.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Our process

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Town-centre premises in Shoreham-by-Sea may have limited parking, so tell us what’s nearby. On estates and business parks it’s normally simpler.

  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.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Warn occupants and staff about the work
  • Move anything stored against the joints
  • Tell us what induction or permit system the site runs

Getting a fixed quote

Why act early in Shoreham-by-Sea

Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds. A failed joint is easier to put right before damp shows inside. Once water gets in, there’s drying out and making good as well.

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

Why appoint us

  • Health and safety: CHAS accredited
  • Work carried out by CSCS-carded applicators
  • One contact handling all your sites
  • Clear, fixed quotes

Read how commercial sealant jobs are priced or how we’re accredited.

How the quote is worked out

We price every job individually. The main factors are:

  • Induction, permit and paperwork requirements
  • Travel to remote or island sites
  • Removal of failed or old sealant
  • Phasing around occupants

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What we need to price the job

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Whether the building will be occupied during the work
  • Specification clauses that apply
  • Whether an asbestos survey exists
  • Your programme or deadline

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Work for main contractors and building owners

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
