Aftercare for building managers
Once the work is signed off, these steps help:
- Note which joints were done, when, and with what
- Act on the first tear or lifting edge rather than waiting
- Inspect movement joints alongside other routine building checks
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal.
An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load. A sound seal keeps the joint working.
Expansion joint sealing for commercial buildings in Dunbar
Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. If you’re dealing with debris jammed in movement joints and previous reseals laid over old sealant, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Dunbar, preparation and product choice get the time they need.
Travel to smaller places like Dunbar is planned so the work is done in one trip where possible. Send photographs, joint widths and details of the traffic first.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Floors, slabs and movement joints in Dunbar
Dunbar sits close to the coast, within about 1 mile. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so it pays to keep them sealed. Dunbar is on Scotland’s drier eastern side. Cold winters and gritting are hard on any yard or deck joint left open. Resealing before the cold months helps protect the edges.
For an occupier at a site such as Spott Road Industrial Estate, 0.5 miles to the south-east of Dunbar, the joints at loading doors and dock levellers usually see the hardest wear.
Dunbar is about 26 miles east of Kirkcaldy, in East Lothian. We cover commercial sites throughout Dunbar, for single jobs and planned programmes alike. Dunbar is one of 48 places in East Lothian on our list for movement joints. We also cover Edinburgh, some 27 miles away.

Doing it in-house
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Different surfaces, different methods
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. We use a sealant classed for the movement, laid over backing to depth.
Podium joints
Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.

Common problems we fix in Dunbar
When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes, and it’s common on joints sealed in a hurry.
Most enquiries start with one or more of the following:
- Water dripping through deck or ramp joints

FAQs: Dunbar
Can being near the sea in Dunbar affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Would you work within a site like Belhaven Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Why has the sealant in our expansion joints split?
Typically the joint is moving more than the sealant can take. We review the joint design as well as the sealant before pricing.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can you seal joints in cold or wet weather?
Outside work depends on conditions because a damp or frozen joint won’t take a proper bond. Internal floor joints are far less affected.
What guarantee do you give on joint sealing?
The 12-month guarantee applies to the workmanship. Tell us right away if a joint we sealed gives trouble in that time.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
On site: what to expect
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 anything is cut or cleaned, and the work typically takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Where we can, we combine work around Dunbar with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.
- We assess the joints on site or from photos, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Before we start on site
- Warn occupants and staff about the work
- Arrange parking or a loading space
- Send any specification or drawings in advance
