Floor joint sealing in Walston

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, 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 Walston. We will confirm the plan with the fixed quote.

  1. First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
  2. The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. We vacuum each run and prime it if the chosen product requires a primer.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

Getting the site ready

  • Send your site hours and access windows
  • Point out any areas we must not close
  • Let us know about inductions and permits

Ask for a quote

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Floor joint sealing in Walston, done properly

Not every floor joint we treat is in a warehouse. Retail units, showrooms and trade counters have slab joints crossed by trolleys, footfall and cleaning machines, and an open, grimy joint line looks poor as well as catching wheels. A flush, well-finished joint tidies the whole floor. If you’re dealing with a gap opening alongside old joint filler and broken arrises where pallet trucks cross, we can put it right, whatever the surface. A single leaking joint is often how a building in Walston first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Weather windows decide external joint work around a place like Walston: sealant needs a dry joint and a temperature within its range, so dates have some give. Inside slabs aren’t affected and can be scheduled around the occupier.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What we’re called out for in Walston

Pallet-truck and forklift wheels concentrate weight on a tiny contact patch. Where a joint is open, the wheel dips and strikes the far edge and those knocks chip the edge apart bit by bit.

Clients usually get in touch after noticing one or more of the following:

  • A gap opening alongside old joint filler
  • Unfilled floor joints collecting dirt and grit
  • Cracked and crumbling joint fill
  • Sealant pulled out along a truck route

Hospital campuses such as Kello Hospital (to the south of Walston) grow in stages, leaving movement joints wherever new blocks meet old.

Questions to ask before you book

  • Is the sealant right for the movement and the substrate?
  • How they’ll work around occupants
  • The terms of the workmanship guarantee
  • Proof of insurance

Questions to ask before you appoint anyone

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

When it isn’t the sealant

Some faults sit outside our scope, and we say so rather than covering them up:

  • Unstable slabs moving under traffic
  • Joint edges that have already broken away, which need repairing before filling (we’ll tell you if so)
  • Worn screed or surface finishes

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Joints and surfaces we work on

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

Questions we are asked in Walston

Is a smaller place like Walston outside your area?

No. Small places get the same service as large ones. We cover the whole of Scotland. Where we can, we group nearby jobs to make the most of each trip.

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

Typically not: we work in sections and hand each one back once it has cured. We agree the sequence and timings with you before we start.

Are your applicators CSCS-carded?

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

Can you phase floor joint work around operations?

We phase it. Areas are taken out of use a section at a time. Tell us your site hours and access windows and we’ll plan around them.

Why is there a gap next to the joint filler?

Young concrete carries on shrinking for a long time and a stiff filler can separate down one side. A top-up normally puts it right.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Owners, agents and contractors

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

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

Joints that move: notes for Walston

Walston is in the east of Scotland, which is drier than the west. Frost and winter road salt still work into open joints in car parks and yards. Autumn is a sensible time to seal them.

After the work

For the best life from the joints:

  • Keep grit out of unfilled joints in the meantime
  • Record damaged joints with a photo and a location
  • Start with the dock areas, where joints fail soonest
  • Mention any aggressive cleaning regime at quote stage

Problems inside the 12-month guarantee period are ours to put right. After that, a check before your busiest period keeps small repairs small.

A broken joint on a main route is crossed by every truck on that route. Early treatment protects wheels, loads and drivers as much as the floor.
