Facade sealing in Birling Gap

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Looking after the joints

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Insist on a full cut-out when joints are renewed
  • Share access with other external trades
  • Don’t wait for a second leak before calling
  • Walk the elevations once or twice a year

Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; record the locations.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos.

Facade sealing in Birling Gap

Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. If you’re dealing with weathered joints at frame-to-structure perimeters and water coming in around window frames, we can put it right, on coping and flashing joints, perimeter joints where frames meet the structure and cladding panel joints alike. One point of contact handles commercial sealant work in Birling Gap from the first photos to the final walk-round, whether it’s one building or several.

For a site near Birling Gap, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we will quote to suit.

Our 12-month guarantee is about workmanship, not 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.

Our process

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If others near Birling Gap need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for 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

  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand

What the job involves on each surface

Window and door perimeters

Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each surface.

Cladding panel joints

On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them to the correct depth.

Your questions answered

Can you take on a job at a hospital such as Eastbourne District General Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Our building in Birling Gap is near the coast: does that change the sealant?

It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Can you work while the building is occupied?

Typically, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Can you just add new sealant on top?

No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.

When something else is needed

Being straight saves everyone time. New sealant won’t cure:

  • Damaged frames that need replacing
  • Damp caused by condensation inside the building
  • Joints whose design needs changing by the specifier

Not sure which it is? You can call 01277 525 020 or use the quote form and we will tell you honestly.

Joints and surfaces we work on

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

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

What affects the price in Birling Gap

Before we quote, we look at:

  • Any access equipment needed
  • Specialist products, such as fire-rated or hygienic sealants
  • Induction, permit and paperwork requirements
  • Phasing around occupants

Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Details that help us quote

We can often quote from photos and a few details. It helps to include:

  • Anything awkward about access or site hours
  • Photos of the joints, close up and from further back
  • Whether the building will be occupied during the work
  • Asbestos survey details if the building is older

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email us.

Facade sealing in Birling Gap: the local picture

Birling Gap lies within about 1 mile of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. At about 54 miles from central London, Birling Gap is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

For a contractor working at a hospital such as Eastbourne District General Hospital, 4.1 miles to the north-east of Birling Gap, perimeter and facade sealing is planned around patients and deliveries. Historic houses such as Alfriston Clergy House, 4.7 miles to the north-west of Birling Gap, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. University estates such as University of Brighton (2.8 miles east of Birling Gap) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Birling Gap is about 5 miles south-east of Seaford, in East Sussex. Across the BN20 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across East Sussex, 308 places are covered, Birling Gap among them. Sites around Brighton have their own page, roughly 16 miles from Birling Gap.

Business premises anywhere in BN20 are within our area for facade joints. Just outside Birling Gap, we also work in East Dean (1 mile north), Friston (1 mile north), Meads (3 miles east), Holywell (3 miles east) and Old Town (3 miles north-east).
