Need fire stopping in Lower Gledfield?

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

After the work

After handover, a little attention goes a long way:

  • Don’t let anyone top up a fire seal with the wrong product
  • Record which product was used where
  • Have penetrations checked while they can still be seen
  • Check risers and ceiling voids after each round of works

Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original, or a new specification from the designer.

Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, which saves guesswork.

About our fire stopping in Lower Gledfield

No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. We work on joints between fire-resisting walls and floors, linear gaps at wall heads and service gaps in risers, and what we’re called in for most is openings left by services added after handover and non-fire-rated filler around services. Most enquiries from Lower Gledfield start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Hotels and care homes around smaller places like Lower Gledfield often have services added during refurbishment. We fit the specified fire-rated sealant as its published detail shows and raise it if another product is needed.

A 12-month guarantee applies to all our work in Highland. If an installation problem shows up, speak to us on 01277 525 020 or email us and we will arrange a return visit.

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Travel to smaller Scottish places like Lower Gledfield is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. External joints need a dry spell as well.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Preparing the site

  • Confirm the product named in the specification
  • For older buildings, check the asbestos register before work
  • Clear stock, furniture or equipment away from the joints

Questions we’re asked in Lower Gledfield

Is Lower Gledfield too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across every Scottish council area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

How do Scotland’s building standards affect fire-rated sealant in Lower Gledfield?

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. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

What about RAMS and site documents?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Why deal with it now?

A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail, and doing it once, properly, is cheaper. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Lower Gledfield before they leak.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

What you get with us

  • Public liability insurance in place
  • 12-month guarantee on workmanship
  • Failed material removed, not covered up
  • Commercial sealant work since 2005

Different surfaces, different methods

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones typically call for a collar or wrap. We check the pipe material and diameter against the detail before we start.

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.

Where services cross fire walls in Lower Gledfield

Under the Scottish non-domestic Technical Handbook, clause 2.1.14, penetrations should be fire stopped to at least the wall or floor’s fire resistance duration, with proprietary products, intumescent ones included, tested for their end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

For buildings in and around Lower Gledfield, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail.

Common problems we fix in Lower Gledfield

Plenty of openings were simply never closed. Inspections, refurbishments and ceiling access typically bring them to light.

What tends to prompt an enquiry:

  • Hidden openings found during inspections
  • Old intumescent sealant that has split away
  • Non-fire-rated filler around services
  • Seals that don’t match their tested detail

On a hospital site such as Migdale Hospital, which lies east of Lower Gledfield, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

What your quote should include

  • Will RAMS and insurance details be available?
  • How they’ll work around occupants
  • Health and safety accreditation such as CHAS
  • Will CSCS-carded applicators be on site?

Choosing a commercial sealant contractor

What sealant work can’t fix

Honesty saves time and money. Fresh joints won’t solve:

  • Reviewing a building’s overall fire safety
  • Signing off or certifying a building’s fire stopping
  • Gaps in walls that were never built as compartment walls

Not sure which it is? You can call 01277 525 020 or use the quote form and we will tell you honestly.

Joints and surfaces we work on

  • Linear gaps at wall heads
  • Service gaps in risers
  • Joints between fire-resisting walls and floors
  • Pipe penetrations
  • Small duct penetrations where the tested detail allows
  • Cable penetrations
