How we handle fire stopping in South Nitshill

It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. The enquiries we see most involve expanding foam used as fire stopping and old intumescent sealant that has split away, on service gaps in risers, small duct penetrations where the tested detail allows and linear gaps at wall heads. Most enquiries from South Nitshill start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

In Scotland’s cities, university, hospital and office estates see services added year after year, and new cabling and pipework through compartment walls is a common reason fire stopping gets breached. Intumescent sealant goes in where the specification calls for it, with backing and depth as tested.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

When to bring in a specialist

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

FAQs: South Nitshill

Would you work within a site like Leverndale Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will you work in a care home in South Nitshill without moving residents out?

Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.

Will you sign off the seals for us?

No. Sign-off belongs to the designer or building control, not the installer. We’ll confirm the products and details used and agree any further records when we quote.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

Do you cover South Nitshill?

Yes. Sites across South Nitshill are covered, with one number for every area we cover.

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.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Commercial clients in South Nitshill

We work for building owners and managing agents on everything from one building to a spread of sites around South Nitshill. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. South Nitshill can form part of a wider programme.

When to call us in South Nitshill

Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.

Common reasons buildings call us in:

  • Openings left by services added after handover
  • Openings found when ceilings come down for a refit
  • Non-fire-rated filler around services
  • Fire-rated sealant that has cracked or shrunk back

Shop fits in centres such as Barrhead Shopping Centre, 1.2 miles to the south-west of South Nitshill, can bring new services through fire-resisting walls between units, which then need the specified seal.

What your quote should include

  • Which product they’ll use, and why it suits the joint
  • Whether old or failed sealant will be cut out, not overlaid
  • What the guarantee covers, and for how long
  • Their pre-qualification and accreditations

Choosing a commercial sealant contractor

From enquiry to sign-off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. University, hospital and office estates in Scotland’s cities have their own permits, inductions and sign-in rules. Pass on the site’s contractor rules when you get in touch.

  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.

Before we start on site

  • Tell staff and tenants when we’ll be in
  • Make sure the joints can be reached
  • Point out any areas we must not close

How the job changes by surface

Linear joints

Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, along the full length of the run.

Cables and cable bundles

Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables and we work within those limits.

Where services cross fire walls in South Nitshill

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, with products tested for that end use. We install what’s specified, to the product’s tested detail. The 2 miles around South Nitshill include two care or nursing homes. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product.

In a school such as Barrhead High School, fire-rated sealant goes in around service penetrations where it is specified. Wherever services are added at a hospital such as Leverndale Hospital, 1.9 miles north of South Nitshill, the compartment line has to be made good with the specified product.

South Nitshill is about 1 mile north-east of Barrhead, in Glasgow. We cover commercial sites throughout South Nitshill, for single jobs and planned programmes alike. South Nitshill is one of 171 places in Glasgow on our list.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep product data and details in the fire safety file
  • Settle who seals which penetrations at the start of a project
  • Don’t let anyone top up a fire seal with the wrong product
  • Put resealing into every M&E and fit-out package

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.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open, not months later.
