Commercial sealant contractors for Brae sites

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

Why act early in Brae

A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. In many cases the element is fine and only the seal around it has given up. A careful reseal is a far smaller undertaking than replacement. Around smaller places like Brae, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Resealing early avoids that.

We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.

What you get with us

  • A range of standard colours, depending on the product
  • A Constructionline member, so easy to vet
  • Old sealant cut out, never sealed over
  • Products installed to the manufacturer’s instructions

Commercial sealant contractors for commercial buildings in Brae

On a commercial site, sealant turns up in more places than people expect: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Externally it keeps rain out of frame perimeters, panel joints and movement joints. Our applicators work on both the inside and the outside of the building. We work on window and door perimeters, kitchen worktops and splashbacks and external facade joints, and the usual reasons a site gets in touch are leaks that seem to come through a sealant line and earlier reseals applied straight onto the failed bead. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Brae, that means joint design, primers and backing rod as standard.

In Brae, as anywhere, the first joints to go are normally the ones that work hardest: south-facing perimeters, entrance thresholds and busy washrooms.

For a job around Brae, the Scottish weather is part of the planning: outside joints need dry, frost-clear surfaces, so we agree a window with some give in it. Internal joints can be done whatever the day brings.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Questions we are asked in Brae

Must a hotel around Brae close while you work?

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

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

Yes. Islands are part of our area, Brae included. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

How long does a typical visit take?

It depends on the scope, though a typical visit usually takes part of a day on a small job and longer where several buildings or phases are involved. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

What do you need from us to quote?

Send what you have, even a few photographs and rough lengths. We follow up with questions or a visit where needed, and then a fixed quote for the agreed scope.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

When it isn’t the sealant

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

  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Old mastic that tests positive for asbestos
  • Cracking that needs a structural engineer to look at it

If in doubt, phone 01277 525 020 or email the details over and we will say what we think before you book.

What we seal

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

Sealant on show in Brae’s commercial buildings

Brae is within about 1 mile of the coast. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. We choose a product rated for the exposure, then confirm the colours available for it. Being in the east of Scotland, Brae gets less rain than the west coast. Winter frost and damp frames still stop outside sealing on some days.

Whatever the building in Brae, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material. For a hotel such as The Brae Hotel Shetland, less than half a mile south of Brae, the colour of a joint at the bar or the bath matters to the look of the room.

Brae is in the Shetland Islands. Anywhere in ZE2, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Brae is one of 63 places we cover in the Shetland Islands.

If you need commercial sealant contractors in ZE2, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. For a building on Runafirth, Ladieside and Hevdaland or nearby, we can quote for sealant joints. Just outside Brae, we also work in Sullom (3 miles north), Scatsta (3 miles north-east), Voe (4 miles south-east), Firth (6 miles north-east) and Hogaland (7 miles north). Brae ranks among the main centres of the Shetland Islands, with offices, shops, schools and other public and commercial buildings. For island and remote sites, travel and materials need planning ahead, so include the location in your enquiry.

Keeping the joints sound

Cleaning and maintenance staff play a part too. Share these points with them:

  • Check joints after other trades have worked nearby
  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Add sealant to the planned maintenance inspection list
  • Log reseals in the O&M or maintenance records

In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer, which is how mould gets back in. Your maintenance team can look at extract fans at the same time.

Sealant installed at the same time normally fails in sequence. A few splits this year typically mean more next year. We’ll tell you which sealant joints need doing first and which can wait.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Tell us who will meet us and how to get in at your building near Brae. That goes into the plan alongside the quote.

  1. We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations, or we arrange a site visit.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

What we need from you

  • Confirm the product named in the specification
  • Send asbestos survey details if the building is pre-2000
  • Send your site hours and access windows

Owners, agents and contractors

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Site staff or a sealant specialist?

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.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
