What does a mastic package usually include?
External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging.
Construction mastic in Longformacus
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. Site teams most often ask us about bath and shower joints scraped during the final clean and cracks opening in caulked internal joints, across cladding and panel joints, sanitary and kitchen joints and internal decorators’ caulk. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Longformacus, preparation and product choice get the time they need.
External sealing around Longformacus depends on dry faces and the right temperature. A little flexibility in the programme lets external joints go in on suitable days.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Construction mastic in Longformacus: the local picture
The east of Scotland, where Longformacus is, gets less rain than the west. Frost and condensation on frames and panels can still hold up external mastic on winter mornings. External mastic is planned with the site manager for workable conditions. In Longformacus, as across Scotland, building warrants are issued by the local authority verifier under the Scottish regulations. The mastic package follows the approved specification.
Around Longformacus, as anywhere, a facade joint depends on its sizing, backing rod and preparation.
Longformacus is about 15 miles south-east of Haddington, in the Scottish Borders. We cover commercial sites throughout Longformacus. Longformacus is one of 91 places in the Scottish Borders on our list for mastic packages. We also cover Edinburgh, some 29 miles away.

What we’re called out for in Longformacus
Most mastic snags on new buildings come from sequencing rather than product. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, so they end up back on the snag list.
What tends to prompt an enquiry:
- Snag items on joints that need redoing before handover
- A mastic package split between trades with no clear owner
- Window and door perimeters that won’t pass inspection
- Sealant knocked or painted over by other trades
For contractors building in or near Longformacus, we seal to the drawings, the specification and the programme.
Before you book anyone
- Will CSCS-carded applicators be on site?
- Proof of insurance
- Will RAMS and insurance details be available?
- Which product they’ll use, and why it suits the joint
Why deal with it now?
Getting the mastic contractor involved early pays off. Early involvement means gaps, products and access are sorted before the programme bites. Leave it late and they turn up on the snag list. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Early resealing prevents it.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
Why choose Mastic Doctor in Longformacus

What the job involves on each surface
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area.
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. One applicator team gives the same finish everywhere following the programme.
For managing agents and facilities managers
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Oversized gaps that need packing or adjustment by others
- Joint design decisions that belong to the architect or engineer
If you are not sure, just phone 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.
What we seal
- Cladding and panel joints
- Floor and skirting junctions
- Brick and block movement joints
- Internal decorators’ caulk
- Window and door perimeters
- Sanitary and kitchen joints
