Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Aftercare for building managers
For the best life from the joints:
- Respect the cure time before traffic returns
- Check joint lines on busy aisles regularly
- Keep photos of joints that look like they’re failing
- Put loading bays at the top of the list
Problems inside the 12-month guarantee period are ours to put right. Beyond that, an inspection once or twice a year catches failing joints early.
Joints are easiest to look after when someone checks them regularly. We can quote a programme that starts with the busiest areas and keeps on top of the rest.
How we handle floor joint sealing in Na Gearrannan
Concrete floors in warehouses and factories are cut into bays by saw-cut joints and construction joints, and each joint line is a weak edge that wheels run over all day. We fill or seal them with a product matched to the traffic and the movement so the edges are held up and debris can’t pack in. We work on joints along racking aisles, saw-cut induced joints and forklift and pallet-truck routes, and what we’re called in for most is chipped and spalling edges along forklift routes and trucks and loads jolting over damaged joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Na Gearrannan is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller Scottish places like Na Gearrannan, slabs needing attention are often in agricultural buildings, workshops, schools and hotels. Slabs and yards take vehicles, rain and frost.
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.

Why it’s worth doing now in Na Gearrannan
Open joints are where dirt collects, out of reach of the floor cleaner. In shops, showrooms and clean production areas that matters for hygiene and appearance. Filled joints are far simpler to keep clean. Around smaller places like Na Gearrannan, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you are ready.

Your questions answered
Will you travel to Na Gearrannan on the island?
Yes, Na Gearrannan is within the area we cover. Every Scottish council area is within our area. Ferry times and the weather set the plan, so we ask for photographs and a full list first.
Does a site in Na Gearrannan have to shut while its joints are sealed?
Usually not: we work in sections and hand each one back once it has cured. Tell us which hours and entrances we can use and we’ll plan from there.
What site paperwork can you supply?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards.
What guarantee do you give on joint filling?
There is a 12-month guarantee on our workmanship and the work is covered by public liability insurance.
How long does a job like this take?
That varies with the scale of the job, though a typical visit usually takes a day for smaller units, with bigger warehouse floors programmed over several visits. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Which is better for warehouse joints, filler or sealant?
It depends on the traffic and the movement. Trafficked joints on truck routes usually need a semi-rigid filler to support the edges and joints with more movement take a flexible sealant.
Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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 usually costs more in the end than doing them right.
What the job involves on each surface
Isolation joints at walls and columns
Perimeter and column joints get forgotten, and they collect dust and debris. We include them in the survey.
Saw-cut induced joints
Induced joints are sawn into a new slab to control where it cracks. They start narrow and widen as the concrete dries so trafficked runs need a filler that holds the arrises.
What sealant work can’t fix
Some faults sit outside our scope, and we say so rather than covering them up:
- Structural cracking in the slab
- Slab panels that rock or move under load
- Uneven floors that need grinding or levelling
If you are not sure, just phone 01277 525 020 or email us and we’ll give you a straight answer before you book.

Joints that move: notes for Na Gearrannan
Na Gearrannan sits close to the coast, within about 1 mile. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, which is why split joints are worth sealing before the edges deteriorate. Being in the west of Scotland, Na Gearrannan gets more rain than eastern areas. Open joints in car parks and yards let in more water than in drier areas. Dry spells are used for the external joints.
Once a joint near Na Gearrannan opens up, grit and water get in and the edges start to break; we will tell you if the edges need repairing first. For floors and slabs around Na Gearrannan, the product is chosen for the traffic and the movement at each joint.
