Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Fire stopping in Cruden Bay

We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. The enquiries we see most involve fire seals cut back for extra cables and never reinstated and expanding foam used as fire stopping, on small duct penetrations where the tested detail allows, service gaps in risers and cable penetrations. A specialist sealant contractor works differently from a general builder: on jobs in Cruden Bay, preparation and product choice get the time they need.

Refurbishments in small hotels, schools and care homes around places like Cruden Bay can leave gaps around new services. We fit the specified fire-rated sealant as its published detail shows and raise it if another product is needed.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Service penetrations in Cruden Bay buildings

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, and products should be 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 Cruden Bay, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail.

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. Where we can, we combine work around Cruden Bay with other jobs nearby. Tell us how flexible your dates are.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Preparing the site

  • Tell us which areas need to stay in use
  • Explain the parking and delivery arrangements
  • Warn occupants and staff about the work

Common problems we fix in Cruden Bay

Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.

Site and facilities staff are often the first to spot these:

  • Open linear gaps along the top of fire-resisting walls
  • Openings found when ceilings come down for a refit
  • Fire sealant pulled out of the opening
  • Snag lists that include open service penetrations

For a hotel such as Cruden Bay Hotel, 0.5 miles south-west of Cruden Bay, penetration seals are worth checking after any refit or services upgrade.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • What level of public liability insurance do they hold?
  • Their pre-qualification and accreditations
  • Do they follow the manufacturer’s priming guidance?

Cruden Bay: questions and answers

Which Scottish guidance covers penetration seals in Cruden Bay?

The non-domestic Technical Handbook, clause 2.1.14, expects a penetration to keep at least the wall or floor’s fire resistance period, with proprietary products tested for the use they’re put to. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

Can you produce the fire-stopping design for a job in Cruden Bay?

No, that sits with the designer, fire engineer or building control. We install fire-rated and intumescent sealant around service penetrations and linear gaps where it is specified, to the manufacturer’s tested detail.

Can you send site paperwork?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Can the sealant be colour-matched?

That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we’ll price it properly.

Aftercare for building managers

To get the most from the new sealant:

  • Keep product data and details in the fire safety file
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Ask the designer to confirm details early on refits
  • Look above ceilings when tiles are lifted for other jobs

Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.
