Fire stopping across Dairsie

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Diagnose, treat, sign off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building, and our waste is bagged and taken away as we go. Travel to smaller Scottish places like Dairsie is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. External joints need a dry spell as well.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Getting the site ready

  • Confirm the product named in the specification
  • Tell staff and tenants when we will be in
  • Make sure the joints can be reached

Advice

Fire stopping in Dairsie, done properly

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind. Those on your schedule are closed with the specified product. If you have non-fire-rated filler around services and fire stopping installed outside its tested range, we can put it right, on linear gaps at wall heads, small duct penetrations where the tested detail allows and pipe penetrations alike. Looking for mastic applicators who cover Dairsie? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

In smaller Scottish places like Dairsie, buildings with fire-resisting walls typically include schools, care homes, hotels and health centres. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Common questions from Dairsie clients

Can you take on a job at a hospital such as St Andrews Community Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Is Prestonhall Industrial Estate, near Dairsie, within your area?

Yes. Our area takes in Dairsie and its surroundings, with estates and business parks such as Prestonhall Industrial Estate included. To start, just call 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Do you work in Scotland as well as England?

Building standards in Scotland are separate from England’s, while England relies on Approved Document B. Wherever the site is, our work follows the specification and the tested detail.

Is BS 476 being phased out?

It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence. In Scotland, the Technical Handbook sets its own guidance.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Do you work in Dairsie?

Yes. We take on work across Dairsie, with one number for every area we cover.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Commercial clients in Dairsie

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Dairsie. One quote can cover more than one site, which keeps the paperwork simple.

Cost factors for service penetrations

A fixed quote reflects the actual work. It takes account of:

  • Whether old sealant has to be cut out first
  • Backing rod, priming and other preparation
  • Access and working height
  • Location, for remote and island sites

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

What we need to price the job

A few photographs plus some basic facts will normally do. It helps to include:

  • Whether the building will be occupied during the work
  • Specification clauses that apply
  • Your programme or deadline
  • Access details, including height

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Different surfaces, different methods

Drylining partitions

Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range and we’ll tell you what the detail says instead.

Plastic pipes

Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough, and we will never swap a specified collar for sealant.

Where services cross fire walls in Dairsie

Scotland has its own building standards: the non-domestic Technical Handbook (clause 2.1.14) says service penetrations should be fire stopped to at least the fire resistance duration of the wall or floor, with proprietary products, intumescent ones included, tested for their end use. Our part is installing the specified fire-rated sealant to its tested detail.

Wherever services are added at a hospital such as St Andrews Community Hospital, 5.7 miles to the east of Dairsie, the compartment line has to be made good with the specified product.

Dairsie (Gaelic: Osnaburgh) is about 9 miles south of Dundee, in Fife. Businesses, contractors and managing agents in Dairsie use us for work on service penetrations. We work across 132 places in Fife. There’s a separate page for Dundee, roughly 9 miles from Dairsie.

Aftercare for building managers

To get the most from the new sealant:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Leave fire sealant to cure fully before covering it
  • Have penetrations checked while they can still be seen
  • Make fire stopping part of every scope that crosses a fire-resisting wall

Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.

What we are called out for in Dairsie

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 the usual culprits.

Most enquiries start with something like this:

  • Service penetrations left open after M&E works
  • Improvised or mixed-product fire seals
  • Unsealed joints where partitions meet the slab
  • Seals disturbed by maintenance and left open

For a unit at a site such as Prestonhall Industrial Estate (2 miles south-west of Dairsie), new power or data runs between office and warehouse can breach a compartment wall.
