Facade sealing for Sullom sites

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

General trades versus a specialist

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Facade sealing for commercial buildings in Sullom

A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. Most enquiries involve weathered facade joints that have lost their grip and gaps between rainscreen or cladding panels, on window and door perimeters, shopfront frames and stone and brick facade joints. One point of contact handles commercial sealant work in Sullom from the first photographs to the final walk-round, whether it’s one building or several.

External sealing around Sullom depends on dry faces and the right temperature. A little flexibility in the programme lets external joints go in on suitable days.

A 12-month guarantee applies to all our work. If an installation problem shows up, call the office on 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

Different surfaces, different methods

Render and coated surfaces

Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface.

Sullom: questions and answers

Can you keep pace with our programme in Sullom?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Sullom inside the area you cover, given it’s on an island?

Yes. Islands are part of our area, Sullom included. Island work is planned around ferry crossings and the weather, so photographs and a full list before we travel are essential.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

How is access to upper-level joints handled?

That comes down to the access arranged for the job. When you speak to us on 01277 525 020 or use the quote form, describe the access, and we will agree the approach together.

Can the building stay open while you work?

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

When can you be on site?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

What affects the price in Sullom

The price varies from site to site. It mainly depends on:

  • Backing rod, priming and other preparation
  • Removal of failed or old sealant
  • Site requirements such as inductions and permits
  • Which sealant the job calls for

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

What to include in your enquiry

However big the job, these details speed things up:

  • The asbestos register, for older buildings
  • Whether the building will be occupied during the work
  • Photos of the joints, close up and from further back
  • Anything awkward about access or site hours

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or email drawings and photos.

Mastic packages on Sullom sites

Sullom is within about 1 mile of the coast. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Island jobs, Sullom among them, are planned around the ferry and the forecast. With drawings and the programme in hand, the whole mastic package comes with us.

Window perimeters and facade joints around Sullom need correct width, depth and backing rod as much as a neat finish. For contractors building in or near Sullom, we seal to the drawings, the specification and the programme.

Sullom is in the Shetland Islands. We cover commercial sites throughout Sullom, whether it’s a single job or part of a planned programme. Our the Shetland Islands coverage takes in 63 places.

Work on facade joints is covered throughout ZE2, for business premises of every kind. If your building is just outside Sullom, we cover Scatsta (2 miles east), Brae (3 miles south), Hogaland (4 miles north), Urafirth (5 miles north-west) and Hillswick (5 miles north-west). For island and remote sites, travel and materials need planning ahead, so the full address helps from the start.

Honest limits

Some faults sit outside our scope, and we say so rather than covering them up:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Render or concrete edges that have broken away
  • Providing access systems for the work

Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

What we seal

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

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Record the product and colour used on each elevation
  • Clear debris that holds water against joints
  • Avoid harsh cleaners on facade sealant
  • Share access with other external trades

Record the sealant type and date on the building file. Future work can then match the product and colour without guesswork.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Our process

Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. For work around Sullom, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Getting the site ready

  • Move anything stored against the joints
  • Send your site hours and access windows
  • Send any specification or drawings in advance
