Fire stopping across Brae

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Our process

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Tell us who will meet us and how to get in at your building near Brae. We’ll confirm the plan with the fixed quote.

  1. We read the specification, drawings or penetration schedule you send.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  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. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Move anything stored against the joints
  • Send your site hours and access windows
  • Point out parking and an unloading spot

Advice

Fire stopping in Brae

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. We work on service gaps in risers, pipe penetrations and cable penetrations, and the failures we’re asked to look at most are unsealed penetrations discovered above suspended ceilings and damaged fire seals in risers and voids. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Brae it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Hotels and care homes around smaller places like Brae 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.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Why it’s worth doing now in Brae

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. For buildings near Brae, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Questions we are asked in Brae

How do Scotland’s building standards affect fire-rated sealant in Brae?

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.

Do you seal service penetrations in hotels around Brae?

Yes, to the specification and the product’s tested detail. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.

Do you cover Brae?

Yes. We cover Brae, within our coverage of Greater London, South East England and Scotland. To discuss a job, call 01277 525 020 or email a schedule or drawings.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Do you offer coloured sealant?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

After the work

Keep the joints in good shape with a few simple steps:

  • Get seals inspected before ceilings and boxing close
  • Keep general-purpose fillers away from compartment walls
  • Include service cupboards in routine inspections
  • Agree the fire-stopping specification before services go in

After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.

Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there, not months later.

How the job changes by surface

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening, with backing added if the detail requires it.

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter and we work within those limits.

What sealant work can’t fix

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:

  • Signing off or certifying a building’s fire stopping
  • Writing the fire-stopping specification
  • Fire doors, dampers or other fire safety equipment

If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think.

Where we work in Brae

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

Service penetrations in Brae buildings

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 what’s specified, to the product’s tested detail. Several hotels sit less than 2 miles from Brae. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

Hotels such as The Brae Hotel Shetland (under half a mile south of Brae) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. For buildings in and around Brae, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail.

What affects the price in Brae

Before we quote, we look at:

  • Location, for remote and island sites
  • The site’s rules and procedures
  • The size and state of each joint
  • Which sealant the job calls for

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you are ready.

Details that help us quote

We can often quote from photos and a few details. It helps to include:

  • Specification clauses that apply
  • Approximate linear metres or a joint schedule
  • Anything awkward about access or site hours
  • Whether the building will be occupied during the work

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or ring 01277 525 020 or send photos by email to discuss it first.
