Sealant applicators in Strontian

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. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead, and a backing rod limits the depth to give the sealant room to work. We work on external facade joints, movement joints in walls and floors and kitchen worktops and splashbacks, and the failures we’re asked to look at most are layers of sealant, all of them failing and wall and floor joints that have lost their seal. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Strontian, preparation and product choice get the time they need.

The most common commercial job in Strontian is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

For a job around Strontian, the Scottish weather is part of the planning: 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.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or email the details over and we will come back to it.

Our process

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Where we can, we combine work around Strontian with other jobs nearby. Tell us how flexible your dates are.

  1. First, details reach us through the quote form or a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Getting the site ready

  • For older buildings, check the asbestos register before work
  • Warn occupants and staff about the work
  • Tell us what induction or permit system the site runs

Ask for a quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Looking after the joints

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Add sealant to the planned maintenance inspection list
  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Log reseals in the O&M or maintenance records
  • Keep abrasive pads and scrapers off resealed joints

Add the resealed joints to your planned maintenance inspections. A periodic look catches splits and lifting edges early, especially on exposed elevations and in washrooms. Should something look amiss, you can ring 01277 525 020 or email drawings and photos and send a picture.

Occupiers often notice failing sealant before the facilities team does, and it reflects on how the building is run. Planned replacement saves fielding the same complaint again and again.

What Strontian’s businesses ask us to seal

With the shore within about 1 mile, Strontian counts as a coastal location. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. Sea-facing elevations are normally where failed joints show first. Being in the west of Scotland, Strontian gets more rain than eastern areas. External joints are sealed on dry days, with some flexibility in the dates.

For any commercial premises in Strontian, a lasting joint depends on full removal of the old sealant and clean, dry faces.

Strontian (Gaelic: Sron an t-Sithein) is in Highland. Businesses, contractors and managing agents in Strontian can call on us for sealant joints, as part of our coverage of Highland. Strontian is one of 256 places in Highland on our list for sealant joints. Glasgow is covered too, around 76 miles from Strontian.

Postcode districts covered here: PH36 for sealant joints. Buildings on Dal nan Each and Dal na Mart are within our area. Nearby places we also cover include Acharacle (9 miles west), Ceann Loch Muideart (9 miles north-west), Port Appin (12 miles south-east), Appin (12 miles south-east) and Balliveolan (12 miles south). For island and remote sites, travel and materials need planning ahead, so include the location in your enquiry.

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What we’re called out for in Strontian

Resealing over the top is a false economy we come across often. Fresh sealant won’t stick to the old bead underneath, so the top layer lifts, holds water and hides what’s going on. Getting back to a clean joint then means removing every layer.

If one of these sounds familiar, it’s time for a closer look:

  • Layers of sealant, all of them failing
  • Greasy, split joints in a kitchen or tea point
  • Mouldy silicone around WCs, urinals and vanity tops
  • Weathered facade sealant that no longer flexes

For a hotel such as Strontian Hotel, less than half a mile to the south of Strontian, the colour of a joint at the bar or the bath matters to the look of the room.

What your quote should include

  • How they handle RAMS and site documents
  • Their approach to joint depth and backing
  • Is the sealant right for the movement and the substrate?
  • Whether primer will be used where the manufacturer specifies it

How to choose a sealant contractor

Questions about Strontian

Will our hotel in Strontian need to close for the work?

Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.

Does the sea air around Strontian change the choice of sealant?

It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

What about asbestos in old mastic?

On older buildings, our first request is the asbestos survey. The duty to manage asbestos sits with the dutyholder.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day.

Can areas stay open during the work?

It’s mostly about sequence: areas are phased, access windows agreed and enough washrooms or entrances left in use. Let us know what can’t close and we’ll work around it.

Does commercial sealant work come with a guarantee?

The work is guaranteed for 12 months. Should anything we did fail within that period, let us know.

What the job involves on each surface

Commercial kitchens and tea points

Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. Proper degreasing comes before any new sealant.

Fire-rated seals where specified

Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services and gaps, so we will flag it if the detail needs a different product.

For managing agents and facilities managers

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
