Construction mastic in Belhaven, done properly
On refurbishments, the mastic package typically includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. We work on brick and block movement joints, floor and skirting junctions and cladding and panel joints, and the usual reasons a site gets in touch are snag items on joints that need redoing before handover and inconsistent sealant finishes from plot to plot. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Belhaven, that means joint design, primers and backing rod as standard.
External sealing around Belhaven depends on dry faces and the right temperature. We build some give into the plan and agree it with the site manager.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

How the quote is worked out
Before we quote, we look at:
- Backing rod, priming and other preparation
- How much there is to seal
- The product specified
- Location, for remote and island sites
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Anything awkward about access or site hours
- Any dates the work must fit around
- Any specification or named product
- What the building is and how it’s used
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Questions about Belhaven
Is a hospital such as Belhaven Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is a smaller place like Belhaven outside your area?
Not at all: smaller places are covered as well as towns. We work across every Scottish council area. Where we can, we group nearby jobs to make the most of each trip.
Can you fit around our programme?
We seal plot by plot or floor by floor as areas are released. The sequence is agreed with the site manager at the start and adjusted as things change.
Can fire-rated sealing at service penetrations be included?
Where it’s specified, yes to the tested detail. We will flag if the detail needs a different product.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Can you clear a mastic snag list before handover?
Yes. We clear snags by redoing joints rather than patching them.
Can you work while the building is occupied?
In most cases, yes. We phase the work so most of the building stays in use.
Facades, frames and programmes in Belhaven
Belhaven lies within about 1 mile of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. A 2-mile radius around Belhaven takes in plenty of hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
Recladding or extending a unit at a site like Spott Road Industrial Estate (to the east of Belhaven) brings panel joints and frame perimeters into the programme. Extensions at sites like Belhaven Hospital, under half a mile south-east of Belhaven, normally sit beside working departments, and the mastic follows strict access rules.
Belhaven is about 1 mile west of Dunbar, in East Lothian. We cover commercial sites throughout Belhaven. Belhaven is one of 48 places we cover in East Lothian for mastic packages. We also cover Edinburgh, some 26 miles away.

General trades versus a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
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, which is what makes a joint last.
When to call us in Belhaven
A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly, so depth is controlled with backing rod or bond-breaker tape.
Look out for the following:
- Mastic snags holding up handover
- Missed perimeter joints on a new elevation
- Early adhesion failures on new external joints
- Old sealant on a refurbishment that needs stripping before new work
Hotels like Eden Hotel, 0.7 miles east of Belhaven, rarely close for long, so refurbishment mastic is phased floor by floor.
What your quote should include
- What level of public liability insurance do they hold?
- How they handle RAMS and site documents
- Whether old or failed sealant will be cut out, not overlaid
- How long is the guarantee, and what does it include?
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Put any product change through the designer first
- Keep product details for future maintenance
- Keep scrapers and abrasive pads off new beads
- Don’t force external sealing on a damp or frosty day
Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean so keep them off the joints.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, and the repair falls into the defects period. Proper preparation, with the right silicone first time, keeps it off the defects list.
