Commercial sealant contractors in Sound

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Working on commercial sites near Sound

Sound is within about 1 mile of the coast. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. A matched colour is only half the brief on an exposed frontage. Sound is in the east of Scotland, which is drier than the west. Cold snaps still affect when external joints can be sealed. We plan external frontages and frames around that

A hotel such as The Lerwick Hotel, 0.8 miles north-east of Sound, shows how much sealant a hospitality building has on show, from bathroom joints to the bar. If you have premises on more than one site, say at North Ness Business Park and South Gremista Industrial Estate, one contractor and one quote can cover both.

Sound is about 1 mile south-west of Lerwick, in the Shetland Islands. Across the ZE1 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Sound is one of 63 places in the Shetland Islands on our list for sealant joints.

Work on sealant joints is covered throughout ZE1. Buildings on Quoys Road, South Road and Oversund Road are within our area. We also cover Lerwick (1 mile north-east), Gulberwick (2 miles south-west), Gremista (2 miles north), Grindiscol (2 miles east) and Heogan (2 miles north-east) for sealant joints. As one of the bigger centres in the Shetland Islands, Sound has a broad mix of commercial, public and industrial buildings, and we cover them all. 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.

Near you in Sound

We work on buildings around Gilbertson Park and the streets around them. Nearby you will also find Gilbert Bain Hospital (0.7 miles north-east) and Shetland Museum (1.2 miles north-east). Not far away are Hill of Berry and Clickimin Loch.

Commercial sealant contractors for commercial buildings in Sound

A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Primer is used wherever the manufacturer calls for it on that surface and the joint depth is controlled with backing rod. We work on washrooms and tea points, kitchen worktops and splashbacks and external facade joints, and the failures we’re asked to look at most are water staining near frames, panels or ceilings and weathered facade sealant that no longer flexes. One point of contact handles commercial sealant work in Sound from the first photos to the final walk-round, whether it’s one building or several.

Quotes for commercial sealant in Sound can come from photos and a joint schedule, or from a walk-round, and the scope is set out in writing.

Scottish weather decides a lot about outside work in a place like Sound: sealant needs a dry joint and the right temperature, so external work has a weather window built in. Internal joints can be done whatever the day brings.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

What we can’t put right

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

  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • A dripping trap, valve or pipe behind a fitting
  • Roof leaks that only look like a joint problem

If you are not sure, just speak to us on 01277 525 020 or send photos by email and we will give you a straight answer.

Where we work in Sound

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

Building owners, agents and FMs in Sound

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

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.

Diagnose, treat, sign off

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Tell us who will meet us and how to get in at your building near Sound. We will confirm the plan with the fixed quote.

  1. Send details through our quote form, or ask for a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Where parts of the building must stay open, the work is phased.
  4. Every failed bead is removed rather than covered.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Getting the site ready

  • Make sure the joints can be reached
  • Agree which areas must stay open
  • Confirm the product named in the specification

Getting a fixed quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Common problems we fix in Sound

If sealant tears through its centre, it has failed cohesively. That typically means the joint stretched further than the product could cope with. Replacing it like for like rarely holds, which is why we look at the joint design as well.

Things that normally lead to an enquiry:

  • A top-up bead over failed sealant, now lifting
  • Sanitary sealant that has gone black and patchy
  • Frame mastic that has hardened and come away from the wall
  • Gaps behind commercial kitchen worktops and sinks

Parks like North Ness Business Park, 1.4 miles north-east of Sound, see tenants come and go, and every move-in brings joints to seal.

Before you book anyone

  • Their plan for phasing and protecting the area
  • Whether primer will be used where the manufacturer specifies it
  • Will RAMS and insurance details be available?
  • Is the sealant right for the movement and the substrate?

Questions to ask before you appoint anyone

Surface by surface

Washrooms and toilets

Mould that has grown into washroom sealant can’t usually be cleaned out. The lasting answer is removal, preparation and a new sanitary bead, planned so the building keeps enough facilities in use.

Commercial kitchens and tea points

A smooth, continuous joint is easier to keep clean, and cleanability is part of what an inspector looks at. We seal to a neat, cleanable finish and work around service times you agree with us.

After the work

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Act on the first lifting edges rather than waiting
  • Add sealant to the planned maintenance inspection list
  • Respect the cure time before reopening an area
  • Make sure ventilation in wet areas is switched on and working

Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life, while a neutral cleaner and a soft cloth do no harm.

Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.

Common questions from Sound clients

Does a coastal location like Sound affect which sealant is used?

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.

Will you travel to Sound on the island?

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

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

How is commercial sealant work priced?

Send photographs, drawings or a list of locations. If a visit is needed we will book one, and a fixed quote follows.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Who decides which product is used?

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