About our fire stopping in Gatehouse of Fleet

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. We work on small duct penetrations where the tested detail allows, service gaps in risers and linear gaps at wall heads, and what we’re called in for most is head-of-wall gaps with no fire seal and service penetrations left open after M&E works. Facilities teams, main contractors and managing agents in Gatehouse of Fleet tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Refurbishments in small hotels, schools and care homes around places like Gatehouse of Fleet 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.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Penetration seals near Gatehouse of Fleet

The area within 2 miles of Gatehouse of Fleet holds several hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. 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, using products tested for the way they’re used. We install fire-rated sealant to that tested detail where it is specified.

In a building such as St Mary's Episcopal Church, any service penetration through a fire-resisting wall should be sealed to the specified detail. Hotels like Murray Arms Hotel (under half a mile east of Gatehouse of Fleet) are refurbished in phases, and each phase can open up compartment walls.

Why it’s worth doing now in Gatehouse of Fleet

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Gatehouse of Fleet before they leak.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Our process

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Where we can, we combine work around Gatehouse of Fleet with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Share the asbestos register for older buildings
  • Flag any permit to work we’ll need
  • Point out parking and an unloading spot

Advice

Common questions from Gatehouse of Fleet clients

Is Gatehouse of Fleet too small for you to travel to?

No. Places such as Gatehouse of Fleet are covered as much as the big towns. We work across every Scottish council area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How do the Scottish rules apply to fire-rated sealing in Gatehouse of Fleet?

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. Design sits with the designer and the verifier; installation to the tested detail is our part.

How long before the joints can be used?

We’ll confirm how long the chosen product needs to cure.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

How many days will you need on site?

That varies with the scale of the job, though a typical visit normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we will set out a timescale with the quote.

Can staff carry on working while you’re here?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Looking after the joints

Regular inspection catches problems early. In particular:

  • Check risers and ceiling voids after each round of works
  • Ask the designer to confirm details early on refits
  • Treat an open penetration as a priority repair
  • Foam or ordinary sealant is never a fire-seal repair

After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.

Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job.

For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Reviewing a building’s overall fire safety
  • Walls or floors that aren’t fire-resisting to begin with
  • Openings that need collars, wraps, batts or boards rather than sealant

Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we will tell you honestly.

Surfaces we seal

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

What affects the price in Gatehouse of Fleet

Before we quote, we look at:

  • Access and working height
  • Joint width, depth and condition
  • The total length or number of joints
  • Whether the work must be split into stages

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

Before you send an enquiry

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

  • Any dates the work must fit around
  • Approximate linear metres or a joint schedule
  • Any specification or named product
  • How the joints are reached, and at what height

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
