Facade sealing for Sandwick sites

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

Facade sealing in Sandwick

Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. Most enquiries involve discoloured or dirty facade joints and gaps between rainscreen or cladding panels, across window and door perimeters, coping and flashing joints and stone and brick facade joints. Looking for mastic applicators who cover Sandwick? We’ve been sealing commercial buildings since 2005.

Sites near smaller places like Sandwick can mean longer travel, so the mastic is planned with as few trips as the job allows. Clear drawings, a programme and photos let us bring the right sealants, primers and backing rod first time.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Signs you need facade sealing in Sandwick

The wrong product causes its share of trouble: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.

Look out for the following:

  • Water coming in around window frames
  • Gaps between rainscreen or cladding panels
  • Failed seals around shopfront and entrance frames
  • Weathered facade joints that have lost their grip

For contractors building in or near Sandwick, we seal to the drawings, the specification and the programme.

What your quote should include

  • Can the work be phased to keep areas open?
  • Which product they’ll use, and why it suits the joint
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • The terms of the workmanship guarantee

Choosing a commercial sealant contractor

What the job involves on each surface

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use, and mask the edges carefully.

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface, and areas needing repair are flagged.

New build and refits around Sandwick

Sandwick is within about 1 mile of the coast. 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. For an island location such as Sandwick, work is planned around ferry crossings and the weather. Drawings and the programme let us bring every sealant, primer and backing rod the package needs.

A facade joint near Sandwick lasts when width, depth and backing are right, not just the finish.

Sandwick is in the Shetland Islands. Anywhere in ZE2, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our the Shetland Islands coverage takes in 63 places.

We take on facade joints across the ZE2 postcode area. If your site is on Central Park, Parklands and Aestbrek or close by, send details and we will quote for facade joints. Just outside Sandwick, we also work in Hoswick (1 mile west), Mail (2 miles north), Levenwick (2 miles south-west), Bremirehoull (3 miles north) and Bigton (3 miles south-west). Nearby towns on our patch include Lerwick (11 miles north), Sound (10 miles north) and Scalloway (10 miles north). Sandwick is one of the busier places in the Shetland Islands, and its commercial and public buildings are all within our area. Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

Aftercare for building managers

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Never let anyone seal over old sealant
  • Confirm the survey covers external sealants in older buildings
  • Inspect facade joints on a regular cycle
  • Plan facade sealing alongside redecoration

After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.

Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and cuts time on site.

On site: what to expect

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Where we can, we combine work around Sandwick with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Confirm the product named in the specification
  • Explain the parking and delivery arrangements
  • Warn occupants and staff about the work

Common questions from Sandwick clients

Can you work to our programme on a site in or near Sandwick?

Yes, we work to the programme and the sequence the site sets. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can being near the sea in Sandwick affect the sealant we need?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Can you send site paperwork?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Can you just add new sealant on top?

No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.

How much does the work cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you use silicone for external joints?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.

Quoting for work in Sandwick

To price the job, we consider:

  • Travel to remote or island sites
  • How much existing material needs removing
  • The size and state of each joint
  • Which sealant the job calls for

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’ll explain how it’s made up.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Clear photographs of the problem areas
  • The product your specification calls for
  • The type of building and who uses it
  • Your programme or deadline

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Why it’s worth doing now in Sandwick

Topping up a failed joint normally buys very little time. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. For buildings near Sandwick, dealing with all the failing joints at once saves return trips. Send photos and we will quote for everything together.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
