Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Why act early in Dundonald

Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up and the job grows to repairs as well as sealing. Resealing early keeps the work to sealant. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Resealing early avoids that.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Why appoint us

  • Failed material removed, not covered up
  • Standard and matched colours in many product ranges
  • Specification-led, product-correct work
  • RAL and finish matching where the product range allows

About our expansion joint sealing in Dundonald

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels so the product has to suit both the traffic and the movement. If the arrises are already broken, we’ll say so before sealing and phasing can keep areas working. If you are dealing with damp inside where a wall movement joint has failed and layers of sealant in a movement joint, we can put it right. Most enquiries from Dundonald start with one failed joint and grow into a wider look at the building: 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 Dundonald: sealant needs a dry joint and a temperature within its range. Internal floors can be done whenever suits the site.

Work we carry out in South Ayrshire comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or email us and we will come back to it.

Slabs, ramps and loading bays in Dundonald

The sea is no more than about 3 miles from Dundonald. Open joints in coastal car parks and yards let in salt-laden water as well as grit, and edges left open tend to break up faster. Dundonald has two named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

A healthcare site such as University Hospital Crosshouse (3.3 miles north-east of Dundonald) depends on car parks, ramps and service yards whose joints take traffic all day. Phasing is what makes joint work possible on busy sites such as Moorfield North Industrial Park (2.9 miles north-east of Dundonald): one bay, aisle or car park row at a time. For an occupier at a site such as Moorfield Industrial Estate (2.6 miles north-east of Dundonald), the joints at loading doors and dock levellers usually see the hardest wear.

Dundonald is about 3 miles north-east of Troon, in South Ayrshire. Dundonald sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 48 places across South Ayrshire fall within our area, including Dundonald.

Our process

On arrival, 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 typically takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. For a building near Dundonald, directions, keys and a contact on the day are worth sorting early. We will confirm the plan with the fixed quote.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Tell us your opening times and when work is allowed
  • Let us know about inductions and permits

Work for main contractors and building owners

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Dundonald. Several sites can go on one quote, so there’s one set of paperwork to deal with.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Surface by surface

Car park decks and ramps

Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again flagging broken edges along the way.

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen.

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Changing the joint layout or spacing of a structure
  • Leaks coming from the membrane rather than the joint seal
  • Concrete or masonry repairs along the arrises

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

What we seal

  • Car park decks and ramps
  • Blockwork control joints
  • Podiums and floor movement joints
  • Cladding panel joints
  • Brickwork movement joints
  • Precast concrete panel joints

Common questions from Dundonald clients

Can being near the sea in Dundonald affect the sealant we need?

It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Is Dundonald off your patch?

No. Small places get the same service as large ones. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.

Can you seal car park deck joints?

Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement, and phased work can be planned so parts of the car park stay in use.

Why do our movement joints keep failing?

Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. Working out the cause comes first.

Can you quote from photographs?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and the quote will be based on it.

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Inspect movement joints alongside other routine building checks
  • Keep racking legs and heavy point loads off floor joints
  • Keep traffic off new joints until the cure time is up

Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. A routine sweep is the simplest protection.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint. Catching it early keeps the water outside.
