Fire stopping for businesses in Ninewells

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

Maintenance after handover

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Keep general-purpose fillers away from compartment walls
  • Agree the fire-stopping specification before services go in
  • Keep product data and details in the fire safety file

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

About our fire stopping in Ninewells

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance. We work on joints between fire-resisting walls and floors, linear gaps at wall heads and pipe penetrations, and the usual reasons a site gets in touch are hidden openings found during inspections and non-fire-rated filler around services. Facilities teams, main contractors and managing agents in Ninewells tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Scotland’s non-domestic Technical Handbook says a service penetration ought to match, as a minimum, how long the wall or floor resists fire. For a building in Ninewells, specified fire-rated sealant is installed as the maker’s tested detail describes.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

How the quote is worked out

A fixed quote reflects the actual work. It allows for:

  • Phasing around occupants
  • The product specified
  • Whether old sealant has to be cut out first
  • Travel to remote or island sites

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

What to include in your enquiry

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • What the building is and how it’s used
  • The postcode of the building
  • The asbestos register, for older buildings
  • Approximate linear metres or a joint schedule

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. If you have questions first, call 01277 525 020 or email drawings and photos.

Compartments and services around Ninewells

Six care or nursing homes sit less than 2 miles from Ninewells. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. We install fire-rated sealant to the tested detail where it is specified. The area within 2 miles of Ninewells holds several hotels. 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.

Tenant changes at parks like Dundee Technology Park, 0.6 miles to the west of Ninewells, bring new data and services, and openings through fire-resisting walls need the specified seal. For a site team at a college like Dundee and Angus College - Kingsway Campus, 2.8 miles to the north-east of Ninewells, fire-rated sealing is best scheduled after the summer works. For an estates team at a campus like University of Dundee, which lies east of Ninewells, summer M&E works are typically followed by a round of penetration sealing.

Questions we’re asked in Ninewells

What do Scotland’s building standards say about service penetrations in Ninewells?

Scotland’s non-domestic Technical Handbook covers it in clause 2.1.14: penetrations keep at least the element’s fire resistance duration, with products tested for their end use. Design sits with the designer and the verifier; installation to the tested detail is our part.

Do you cover business parks and estates near Ninewells, such as Dundee Technology Park?

Yes. Our area takes in Ninewells and its surroundings, with estates and business parks such as Dundee Technology Park included. Photos and a short description are enough for a first look.

Will you just go over the old sealant?

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

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

What about RAMS and site documents?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

For managing agents and facilities managers

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

What we can’t put right

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Fire risk assessments, a job for a competent assessor
  • Walls or floors that aren’t fire-resisting to begin with

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly.

What we seal

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

Diagnose, treat, sign off

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Give us the access times and building rules for your premises in Ninewells, and we will plan the work to suit, phased where areas need to stay in use.

  1. First we confirm the product and tested details named in the specification.
  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. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Confirm the product named in the specification
  • Let building users know which areas are affected
  • For older buildings, check the asbestos register before work
