Fire-rated sealing for Rosewell buildings

Scotland has its own building standards: the non-domestic Technical Handbook (clause 2.1.14) says service penetrations should be fire stopped to at least the fire resistance duration of the wall or floor, with products tested for that end use. We install fire-rated sealant to that tested detail where it is specified.

For a building at a site such as IMEX Business Centre, 1.7 miles to the north-west of Rosewell, a check of penetration seals after each fit-out is good practice. Shop fits in centres such as Straiton Retail Park (to the north-west of Rosewell) can bring new services through fire-resisting walls between units, which then need the specified seal. Older community buildings such as Rosewell Parish Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Rosewell is about 2 miles south-west of Bonnyrigg, in Midlothian. Rosewell sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 34 places in Midlothian, from busy centres to rural villages. For work in that direction, see our Edinburgh page, about 7 miles away.

We take on service penetrations across the EH24 postcode area, whatever the building. If your site is on Louisa Square, Shiel Hall Square and Gorton Loan or close by, send details and we’ll quote for service penetrations. Sites close to Rosewell are covered too, including Polton (1 mile north), Roslin (1 mile west), Bonnyrigg (2 miles north-east), Loanhead (2 miles north) and Bilston (2 miles north-west). A short drive away, we cover Dalkeith (4 miles north-east), Penicuik (3 miles west), Gorebridge (4 miles east), Newtongrange (3 miles east), Mayfield (4 miles east) and Shawfair (5 miles north). As one of the bigger centres in Midlothian, Rosewell has a broad mix of commercial, public and industrial buildings, and we cover them all.

Fire stopping for commercial buildings in Rosewell

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, 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. Reproducing the tested arrangement on site is the part we take care of. We work on cable penetrations, service gaps in risers and small duct penetrations where the tested detail allows, and the failures we’re asked to look at most are head-of-wall gaps with no fire seal and fire sealant pulled out of the opening. A single leaking joint is often how a building in Rosewell first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Refurbishments in small hotels, schools and care homes around places like Rosewell 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.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Doing it in-house

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

Our process

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Where we can, we combine work around Rosewell with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.

  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. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  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.

What we need from you

  • Tell us what induction or permit system the site runs
  • Send your site hours and access windows
  • Clear stock, furniture or equipment away from the joints

Advice

Work for main contractors and building owners

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Questions we’re asked in Rosewell

Do you cover business parks and estates near Rosewell, such as IMEX Business Centre?

Yes, sites like IMEX Business Centre are within our area, along with the rest of Rosewell. A few photographs and the unit address let us price the work.

Will you plan work around the academic year at somewhere like University of Edinburgh - Easter Bush Campus?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Do you approve fire stopping for building control?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. Our part is fitting the specified product to its tested detail, and any records you need can be confirmed with the quote.

Is BS 476 being phased out?

From 2 September 2029, Approved Document B in England drops its references to BS 476 classes. The European route, BS EN 13501-2, then applies. Product selection stays with your designer.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Do you have third-party installer accreditation for fire stopping?

No. We are not members of a third-party fire-stopping installer scheme. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. Where a client or main contractor requires a scheme member, we’ll say so straight away rather than waste your time.

Will you come and look before quoting?

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

Different surfaces, different methods

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically and tell you about openings outside the list.

Plastic pipes

Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail, and we won’t substitute it for a specified collar.

What sets the cost

The price varies from site to site. It mainly depends on:

  • Any access equipment needed
  • Induction, permit and paperwork requirements
  • Whether old sealant has to be cut out first
  • The product specified

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

Before you send an enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • The type of building and who uses it
  • The asbestos register, for older buildings
  • Anything awkward about access or site hours
  • Photos of the joints, close up and from further back

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Walls or floors that aren’t fire-resisting to begin with
  • Fire doors, dampers or other fire safety equipment
  • Plastic pipes whose detail calls for a collar or wrap

If in doubt, phone 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

Surfaces we seal

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