For managing agents and facilities managers

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Construction mastic in Auldgirth, done properly

Getting a subcontractor through site induction should be simple. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. If you are dealing with snag items on joints that need redoing before handover and frame gaps too wide for sealant alone, we can help. A specialist sealant contractor works differently from a general builder: in Auldgirth, that means joint design, primers and backing rod as standard.

External sealing around Auldgirth depends on dry faces and the right temperature. A little flexibility in the programme lets external joints go in on suitable days.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

From enquiry to sign-off

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Where we can, we combine work around Auldgirth with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  1. Drawings, specification and programme come to us.
  2. Quantities are measured and a fixed price returned.
  3. The sequence is agreed with the site manager.
  4. Each area is sealed when it’s released.
  5. Joints are prepared, backed and sealed to the specification.
  6. After snagging, the work is handed over under our 12-month guarantee.

What we need from you

  • Arrange parking or a loading space
  • Send asbestos survey details if the building is pre-2000
  • Confirm the product named in the specification

Surface by surface

Bathrooms, en suites and washrooms

In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line and baths are loaded where appropriate before sealing.

Internal decorators’ caulk

Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s paintable and suits gaps that don’t move.

Honest limits

Being straight saves everyone time. Fresh joints won’t solve:

  • Defective windows, doors or glazing units (the supplier or installer’s job)
  • Designing joint widths or choosing the specification (that sits with the designer)
  • Oversized gaps that need packing or adjustment by others

If in doubt, call 01277 525 020 or send photos by email and we’ll say what we think before you book.

What we seal

  • Cladding and panel joints
  • Internal decorators’ caulk
  • Sanitary and kitchen joints
  • Floor and skirting junctions
  • Brick and block movement joints
  • Window and door perimeters

Doing it in-house

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.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Contractors’ notes for Auldgirth

The east of Scotland, where Auldgirth is, gets less rain than the west. Cold, damp starts still stop external sealing on some days. External dates keep a little give. Building work in Auldgirth comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. The mastic package follows the approved specification.

Extensions at sites like Thornhill Hospital (to the north-west of Auldgirth) normally sit beside working departments, and the mastic follows strict access rules.

What we’re called out for in Auldgirth

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.

Clients typically get in touch after noticing one or more of the following:

  • Perimeter gaps outside the sealant’s range
  • Internal caulk splitting as the building dries out
  • Frame perimeters left unsealed or poorly sealed
  • Bath and shower joints scraped during the final clean

Hotels like Friars Carse Country House Hotel (to the south-east of Auldgirth) rarely close for long, so refurbishment mastic is phased floor by floor.
