About our fire stopping in Seamill

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on joints between fire-resisting walls and floors, service gaps in risers and pipe penetrations, and the usual reasons a site gets in touch are damaged fire seals in risers and voids and improvised or mixed-product fire seals. Whether you call it commercial sealant work, mastic application or joint sealing, in Seamill it comes down to the same thing: the right product in a properly prepared joint.

Hotels and care homes around smaller places like Seamill often have services added during refurbishment. A round of checks after M&E work is good practice, and any gaps found are sealed where fire-rated sealant is specified.

Work we carry out in North Ayrshire comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email a schedule or drawings and we will come back to it.

What the job involves on each surface

Cables and cable bundles

Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and we tell you if the bundle exceeds what sealant covers.

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork usually needs a different solution set by the designer, and we’ll say if that applies.

What we’re called out for in Seamill

Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped.

If one of these sounds familiar, it’s time for a closer look:

  • Fire-rated sealant that has cracked or shrunk back
  • Unsealed openings around new pipes and cables
  • Hidden openings found during inspections
  • Unsealed joints where partitions meet the slab

Hotels such as Seamill House Hotel, less than half a mile north-east of Seamill, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Questions to ask before you book

  • Which product they’ll use, and why it suits the joint
  • Their pre-qualification and accreditations
  • How the joint faces will be prepared and primed
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Our contractor checklist

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Fire risk assessments, a job for a competent assessor
  • Large openings beyond what any sealant detail covers
  • Writing the fire-stopping specification

If in doubt, ring 01277 525 020 or email drawings and photos and we will say what we think.

Surfaces we seal

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

Where services cross fire walls in Seamill

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. There are a number of hotels within about 2 miles of Seamill. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.

On a hospital site such as Lady Margaret Hospital, 5.8 miles to the north of Seamill, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Older community buildings such as Barony Parish Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Seamill is about 3 miles north-west of Ardrossan, in North Ayrshire. Our applicators travel to Seamill for work on service penetrations, handled exactly as we handle every other area.

How the quote is worked out

The price varies from site to site. Expect it to depend on:

  • How much existing material needs removing
  • How much there is to seal
  • The size and state of each joint
  • Induction, permit and paperwork requirements

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Before you send an enquiry

A good diagnosis starts with the right details. Let us know:

  • Any specification or named product
  • The site address and postcode
  • The type of building and who uses it
  • Photos of the joints, close up and from further back

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or send details through our quote form.

Diagnose, treat, sign off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Tell us who will meet us and how to get in at your building near Seamill. We’ll confirm the plan with the fixed quote.

  1. We read the specification, drawings or penetration schedule you send.
  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. 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

  • Move anything stored against the joints
  • Arrange parking or a loading space
  • Let building users know which areas are affected

Related advice

When to bring in a specialist

Some joints are best left to specialists: 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.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Questions we’re asked in Seamill

Is Seamill too small for you to travel to?

Not at all. Seamill is within our area. We cover the whole of Scotland. Send photographs 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 Seamill?

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

How long does a job like this take?

It depends on the scope, though a typical visit typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Will you just go over the old sealant?

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

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
