Fire stopping for Kilmuir sites

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

Our process

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. For work around Kilmuir, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Tell us which areas need to stay in use
  • Point out parking and an unloading spot
  • Send asbestos survey details if the building is pre-2000

Fire stopping in Kilmuir

A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. We work on pipe penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows, and what we’re called in for most is open linear gaps along the top of fire-resisting walls and builders’ foam or ordinary silicone in compartment walls. Most enquiries from Kilmuir start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

For a building near Kilmuir, we plan fire-rated sealing so it’s finished in one visit where possible. Send the specification and photos of the openings, with sizes if you have them.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Brief every trade that openings they make must be sealed
  • Include service cupboards in routine inspections
  • Ask which product is in place before decorating
  • Settle who seals which penetrations at the start of a project

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.

Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job; found late, it can be one of many.

When to call us in Kilmuir

Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it and has to be removed.

Typical triggers for a call:

  • Old intumescent sealant that has split away
  • Open linear gaps along the top of fire-resisting walls
  • Seals disturbed by maintenance and left open
  • Service penetrations left open after M&E works

For a hospital such as County Community Hospital (3.4 miles south-west of Kilmuir), penetration sealing is usually phased ward by ward, with infection-control rules agreed first.

Choosing a commercial sealant contractor

Leave it or put it right?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Resealing early avoids that.

A quote for service penetrations depends on how many there are, their condition and the access. Call for a quote.

Questions about Kilmuir

Is Kilmuir too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers all of Scotland, cities, towns and islands alike. Good photographs up front let us bring everything on the first visit.

Which Scottish guidance covers penetration seals in Kilmuir?

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. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

What will the job cost?

Each job is quoted on its own details. To get one, call 01277 525 020 or send details through our quote form.

When can the area be used after sealing?

We will confirm how long the chosen product needs to cure.

When can you be on site?

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

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Fire risk assessments, a job for a competent assessor
  • Signing off or certifying a building’s fire stopping
  • Writing the fire-stopping specification

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

Where we work in Kilmuir

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

Should maintenance staff do it?

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.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Service penetrations in Kilmuir 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.

Halls and meeting rooms at places like Parish Church sometimes gain new services, and any compartment wall crossed needs the specified seal.
