Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Stop forks and pallets being dragged across joints
- Treat loading bay joints first if they’re failing
- Walk the main routes and inspect joint lines on a regular cycle
- Keep trucks off new joints until we say they’re ready
Once cured, the joints get cleaned along with the slab. If you use strong chemicals or hot-water washing, mention it when we quote so we choose something that tolerates them.
A broken joint on a main route is crossed by every truck on that route. Sorting it early looks after your equipment as well as the slab.
When to call us in Johnstone
A slab keeps shrinking for a long time after it is cast, and saw-cut joints give that shrinkage a planned place to crack. As the panels contract, the joints widen so a filler put in early may separate along one side.
If one of these sounds familiar, it’s time for a closer look:
- Chipped and spalling edges along forklift routes
- A gap opening alongside old joint filler
- Sealant pulled out along a truck route
- Saw-cut joints left open and packed with grit
Across sites such as Mossedge Industrial Estate, 1.9 miles north-east of Johnstone, floor and movement joints can be sealed in phases so units keep working.

Our process
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a unit on an estate in Johnstone, tell us about yard access and site rules. Central premises can need a little more planning for parking.
- First, the zones and order of work are agreed with you.
- We point out joints whose edges need repairing first.
- Failed material and debris are removed and the joint cleaned.
- The chosen filler or sealant goes in flush with the slab.
- Each area is handed back when ready for traffic.
What we need from you
- Tell us which areas need to stay in use
- Have the specification and drawings to hand
- Point out parking and an unloading spot

Johnstone is on Scotland’s wetter western side. Open joints in car parks and yards let in more water than in drier areas. External sealing is booked for dry spells, with some give in the dates.

What affects the price in Johnstone
Your fixed quote is built from the real scope. It takes account of:
- The site’s rules and procedures
- Which sealant the job calls for
- Removal of failed or old sealant
- The total length or number of joints
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
What we need to price the job
It doesn’t need to be a full survey. A few details are enough to get going:
- Whether an asbestos survey exists
- Drawings or a marked-up plan, if available
- Photos of the joints, close up and from further back
- The type of building and who uses it
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
What happens if it’s left?
Not every joint needs stripping out completely. If old material is sound on one face and only a fine gap has opened, it may not all have to come out, and we’ll say which joints need what. Water through a failed joint in a building in Johnstone can spoil ceilings, floors and stock. Early action limits what needs repairing.
Pricing floor joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

- Sealing commercial buildings since 2005
- Failed material removed, not covered up

Questions we’re asked in Johnstone
Must our site in Johnstone stop work while the joints are done?
In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.
Do you cover business parks and estates near Johnstone, such as St James Business Centre?
Yes. Our area takes in Johnstone and its surroundings, with estates and business parks such as St James Business Centre included. Photos and a short description are enough for a first look.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
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 will confirm them with the quote.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you repair broken joint edges?
Edge condition is recorded when we look at the floor. Damaged edges are flagged up front so the filling isn’t wasted.
Surface by surface
Semi-rigid joint fillers
On industrial routes, a semi-rigid filler is often the right choice. They are installed to the depth the manufacturer specifies and finished flush.
Forklift and pallet-truck routes
Trucks running over open joints wear wheels and shake loads. A filled joint lets wheels roll across and protects the floor.
