Questions about Dolphinton
What do Scotland’s building standards say about service penetrations in Dolphinton?
Under Scotland’s non-domestic Technical Handbook (clause 2.1.14), service penetrations should keep at least the wall or floor’s fire resistance duration, using products tested for their end use. We install what has been specified, to the manufacturer’s tested detail, while design and approval sit with the designer and the verifier.
Would you work within a site like Castle Craig Hospital?
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.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can staff carry on working while you’re here?
In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Fire stopping in Dolphinton
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. Those on your schedule are closed with the specified product. Site teams most often ask us about unsealed joints where partitions meet the slab and unsealed penetrations discovered above suspended ceilings, on linear gaps at wall heads, joints between fire-resisting walls and floors and cable penetrations. Looking for mastic applicators who cover Dolphinton? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Around smaller places such as Dolphinton, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Those penetrations are closed with the product the specification names, built up as tested.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Why act early in Dolphinton
Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Dolphinton before they leak.
Pricing service penetrations depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Tell us who will meet us and how to get in at your building near Dolphinton. That goes into the plan alongside the quote.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Getting the site ready
- Tell us your opening times and when work is allowed
- Tell us what induction or permit system the site runs
- Arrange parking or a loading space

When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Reviewing a building’s overall fire safety
- Openings that need collars, wraps, batts or boards rather than sealant
- Walls or floors that aren’t fire-resisting to begin with
If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Fire-rated sealing for Dolphinton buildings
Scottish guidance (non-domestic Technical Handbook, clause 2.1.14) asks that penetrations match at least the fire resistance period of the element they pass through, using products tested for the way they’re used. Our part is installing the specified fire-rated sealant to its tested detail.
On a hospital site such as Castle Craig Hospital (2.9 miles south-east of Dolphinton), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

What we are called out for in Dolphinton
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.
What tends to prompt an enquiry:
- Seals disturbed by maintenance and left open
- Open linear gaps along the top of fire-resisting walls
- Seals that don’t match their tested detail
- Fire-stopping items raised at inspection or handover
Older community buildings such as Dolphinton Parish Church And Churchyard that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Questions to ask before you book
- Will CSCS-carded applicators be on site?
- How joint depth will be controlled
- Their plan for phasing and protecting the area
- Their pre-qualification and accreditations
When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
