How we handle fire stopping in St Marys
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail. We work on pipe penetrations, service gaps in risers and linear gaps at wall heads, and what we’re called in for most is fire seals cut back for extra cables and never reinstated and unsealed joints where partitions meet the slab. Facilities teams, main contractors and managing agents in St Marys tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Older stone and tenement buildings in Scotland’s cities have normally been re-serviced many times. Wall type and service type decide the product, so both are checked before sealing, and design questions go to the designer or verifier.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Signing off or certifying a building’s fire stopping
- Walls or floors that aren’t fire-resisting to begin with
- Fire risk assessments, a job for a competent assessor
Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.
Surfaces we seal
- Service gaps in risers
- Cable penetrations
- Pipe penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
Leave it or put it right?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach. Failed sealant in a shared building in St Marys can affect more than one owner. Acting early avoids disputes and bigger repairs.
Pricing service penetrations depends on quantities, condition and access. Ask us for a fixed quote.

What we are called out for in St Marys
Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
These are often picked up first by site or facilities staff:
- Head-of-wall gaps with no fire seal
- Seals that don’t match their tested detail
- Unsealed penetrations discovered above suspended ceilings
- Non-fire-rated filler around services
At a healthcare site like Kings Cross Hospital, 1.5 miles to the south-east of St Marys, new services through compartment walls are a constant, and each needs the specified seal.

What the job involves on each surface
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers.
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed, and we work within it.
What sets the cost
We price every job individually. The things that drive the figure:
- Backing rod, priming and other preparation
- Specialist products, such as fire-rated or hygienic sealants
- Whether old sealant has to be cut out first
- Any access equipment needed
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Details that help us quote
Whether it’s one area or a whole building, the same details help:
- Any specification or named product
- Asbestos survey details if the building is older
- Your programme or deadline
- Anything awkward about access or site hours
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to speak to us on 01277 525 020 or send details through our quote form with what you know.
Compartments and services around St Marys
Several hotels sit less than 2 miles from St Marys. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. The 2 miles around St Marys include four care or nursing homes. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. We install fire-rated sealant to the tested detail where it is specified.
At a college such as Dundee and Angus College - Kingsway Campus, 1.6 miles east of St Marys, checking penetration seals after summer M&E works is good practice. Industrial units on estates such as Dryburgh Industrial Estate, 0.6 miles south of St Marys, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

Questions we are asked in St Marys
Would you work within a site like Kings Cross Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will you take on work at estates like Dryburgh Industrial Estate, close to St Marys?
Yes. We cover St Marys and the area around it, including industrial estates, business parks and retail parks such as Dryburgh Industrial Estate. To start, just call the office on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Is BS 476 being phased out?
For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, subject to transitional arrangements. In Scotland, the Technical Handbook sets its own guidance, including clause 2.1.14 on service penetrations.
Is fire stopping in Scotland covered by different guidance?
Our area runs from Greater London and the South East to every part of Scotland. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, using products tested for their end use.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Do you seal openings left by new services?
Yes, provided a specification covers them. New services after M&E works often breach existing seals.

Diagnose, treat, sign off
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. In a Scottish city, kerbside space and loading need planning, especially near the centre. Shared closes, stairs and the property factor may need to be part of the plan.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
