Floor joint sealing for Lochboisdale sites

Floor joint sealing for commercial buildings in Lochboisdale

Few warehouses can shut a whole floor while joints are done, so the work is split into zones and treated one area at a time. Tell us your site hours and access windows and we will plan around them so the rest of the operation keeps going. Most enquiries involve broken arrises where pallet trucks cross and a gap opening alongside old joint filler, across saw-cut induced joints, loading bays and forklift and pallet-truck routes. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Lochboisdale, preparation and product choice get the time they need.

In smaller places such as Lochboisdale, the joints we’re asked about sit in workshops, farm sheds, schools and halls. Slabs and yards take vehicles, rain and frost.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What the job involves on each surface

Construction joints

Where a day joint crosses a truck route, its edges take heavy punishment. We look at how much they are moving before choosing the treatment.

Isolation joints at walls and columns

Isolation joints separate the slab from walls, columns and plinths so it can move independently. Something flexible normally suits them, not a stiff filler.

Traffic, movement and joints around Lochboisdale

Lochboisdale is within about 1 mile of the coast. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so a failed joint lets more in and the edges break up sooner. Lochboisdale is in the west of Scotland, the wetter side of the country. Open joints in car parks and yards let in more water than in drier areas. Outside joints are sealed in dry spells, so dates have some give.

A joint near Lochboisdale that has lost its sealant lets in water and grit, and the edges suffer next. In and around Lochboisdale, the right filler or sealant for each joint depends on the traffic and the movement it takes.

Lochboisdale is in Na h-Eileanan Siar. We cover commercial sites throughout Lochboisdale, whether it’s a single job or part of a planned programme. Lochboisdale is one of 87 places in Na h-Eileanan Siar on our list.

FAQs: Lochboisdale

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

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.

Will our site in Lochboisdale have to close for joint sealing?

Typically not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Is it normal for joint filler to separate?

It can be shrinkage, contamination on the joint faces or a product unsuited to the movement. We look at which it is before recommending anything.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

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.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Leave it or put it right?

Every jolt over a broken joint passes into the truck, the load and the driver. That means extra wear on wheels and a rougher ride for staff, which nobody budgets for. A filled joint takes most of that out. Renewing every failing joint on one visit is the sensible approach for a place like Lochboisdale. Send photos and we’ll quote for everything together.

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote once you have the details.

What sealant work can’t fix

We check first that sealant really is the fix. It isn’t the answer for:

  • A floor that is out of level for the racking or trucks
  • Cracks across panels caused by settlement or overload
  • Slab panels that rock or move under load

Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Joints and surfaces we work on

  • Forklift and pallet-truck routes
  • Loading bays
  • Joints along racking aisles
  • Saw-cut induced joints
  • Construction joints
  • Retail and showroom floors

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Walk the main routes and inspect joint lines on a regular cycle
  • Mention any aggressive cleaning regime at quote stage
  • Start with the dock areas, where joints fail soonest
  • Ask drivers not to drag forks or pallets

If a joint we filled starts to break up within 12 months, tell us and we will arrange a look. 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 a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes a day for smaller units, with bigger warehouse floors programmed over several visits. Tell us who will meet us and how to get in at your building near Lochboisdale. That goes into the plan alongside the quote.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. The treatment and the zones are set out in a fixed quote.
  3. Old fill and packed debris come out until both faces are sound.
  4. Dust is vacuumed out and primer applied where specified.
  5. The joint is filled to its specified depth and trimmed level.
  6. We hand each phase back when it can take traffic.

Preparing the site

  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings
  • Flag any permit to work we’ll need

Request a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
