Commercial sealant contractors for businesses in Lochranza

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Broken glass or blown double-glazed units
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)

If you’re not sure, just call the office on 01277 525 020 or email the details over and we will give you a straight answer.

Where we work in Lochranza

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

Commercial mastic work in Lochranza

We’ve applied sealant on commercial sites for over 20 years: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. We work on movement joints in walls and floors, washrooms and tea points and window and door perimeters, and what we’re called in for most is window and door perimeter joints that have cracked open and gaps behind commercial kitchen worktops and sinks. A specialist sealant contractor works differently from a general builder: on jobs in Lochranza, preparation and product choice get the time they need.

Occupied buildings in Lochranza need the work phased: washrooms in turn, floors in sections and entrances kept open.

Scottish weather decides a lot about outside work in a place like Lochranza: 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.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Questions about Lochranza

Our building in Lochranza is near the coast: does that change the sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Is Lochranza too far out for you?

No. Small places get the same service as large ones. Every Scottish council area is within our area. Good photographs up front let us bring everything on the first visit.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

What do you need from us to quote?

Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. For a fixed quote, send details through our quote form.

Which site documents can you send us?

The paperwork is agreed with the quote: RAMS, an insurance certificate and CSCS details are the usual requests. Every applicator holds a CSCS card.

Is it OK to apply fresh sealant over existing beads?

The old bead is stripped out first. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.

Will the building have to shut during the work?

It’s mostly about sequence: we agree access windows, phase the work and keep enough facilities open. Tell us what has to stay open and we’ll plan the job around it.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be 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.

What happens if it’s left?

Some low prices are low because nothing gets cut out. New sealant laid on old silicone has nothing to bond to, so it peels. Every quote we give includes full removal and preparation, because that’s what makes the new bead last. Around smaller places like Lochranza, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Resealing early avoids that.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Take a look at what affects the cost or how we’re accredited.

How the job changes by surface

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. We’ll recommend the right filler or sealant for the traffic and movement.

Washrooms and toilets

Washroom joints take water, cleaning chemicals and constant use. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, with phased work so some facilities stay open.

Working on commercial sites near Lochranza

Lochranza sits close to the coast, within about 1 mile. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. Sea-facing elevations are typically where failed joints show first. Lochranza is on Scotland’s wetter western side. Frontage work is booked with a few days’ give for the weather. Elevations facing the weather usually show failed joints first

Colour matters on frontages and fit-outs, so the quote confirms which colours the chosen product comes in. For any commercial premises in Lochranza, a lasting joint depends on full removal of the old sealant and clean, dry faces.

Lochranza is about 20 miles west of Saltcoats, in North Ayrshire. Commercial clients in Lochranza use us for work on sealant joints, as part of our coverage of North Ayrshire. Our North Ayrshire coverage takes in 54 places, from busy centres to rural villages. Glasgow is covered too, some 41 miles away.

Postcode districts covered here: KA27 for sealant joints. Buildings on Bearlach Dearg and Newton Road are within our area. We also cover Pirnmill (6 miles south-west), Corrie (8 miles south-east), Whitehouse (10 miles north-west), Kingarth (11 miles east) and An Tairbeart (12 miles north-west). Where a site is remote or on an island, travel and materials need planning ahead, so the full address helps from the start.

Advice

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.

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.
