Fire stopping for Carrington sites

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

Your questions answered

Does your area include sites such as Dalhousie Business Park, near Carrington?

Yes. Estates, retail parks and business parks around Carrington, Dalhousie Business Park among them, are all within reach. To start, just call 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

What do Scotland’s building standards say about service penetrations in Carrington?

Scotland’s non-domestic Technical Handbook covers it in clause 2.1.14: penetrations keep at least the element’s fire resistance duration, with products tested for their end use. We install what has been specified, to the manufacturer’s tested detail, while design and approval sit with the designer and the verifier.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

What do you charge?

We don’t publish prices, as every site differs. With photographs or drawings, we can give you a fixed quote.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Fire stopping for commercial buildings in Carrington

Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. Where there isn’t one, the designer or fire engineer needs to set one first. If you are dealing with unsealed joints where partitions meet the slab and unsealed penetrations discovered above suspended ceilings, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Carrington, that means joint design, primers and backing rod as standard.

Hotels and care homes around smaller places like Carrington 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.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Different surfaces, different methods

Drylining partitions

Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range.

Small ducts

Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork typically needs a different solution set by the designer, and we will say if that applies.

Our process

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For work around Carrington, we aim for one trip, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  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. 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

  • Let building users know which areas are affected
  • Make sure the joints can be reached
  • Point out any areas we must not close

Getting a fixed quote

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or use the quote form to discuss it first.

What sealant work can’t fix

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Gaps in walls that were never built as compartment walls
  • Fire risk assessments, a job for a competent assessor
  • Plastic pipes whose detail calls for a collar or wrap

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

Surfaces we seal

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

Service penetrations in Carrington 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. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

Offices at parks like Dalhousie Business Park, 2 miles to the north of Carrington, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. Halls and meeting rooms at places like Carrington Parish Church sometimes gain new services, and any compartment wall crossed needs the specified seal.

Carrington is about 3 miles south of Bonnyrigg, in Midlothian. We cover commercial sites throughout Carrington, whether it’s a single job or part of a planned programme. Our Midlothian coverage takes in 34 places, from busy centres to rural villages. There’s a separate page for Edinburgh, roughly 9 miles from Carrington.

Business premises anywhere in EH23 are within our area for service penetrations. If your site is on Main Street, Primrose Gardens and Manse Road or close by, we can quote for service penetrations. Sites close to Carrington are covered too, including Arniston (2 miles east), Birkenside (2 miles east), Gorebridge (2 miles north-east), Gowkshill (2 miles north-east) and Newtongrange (3 miles north-east). A short drive away, we cover Bonnyrigg (3 miles north), Dalkeith (4 miles north), Penicuik (5 miles west), Loanhead (4 miles north-west), Mayfield (3 miles north-east) and Shawfair (6 miles north).

Local landmarks in Carrington

For rail, the closest station is Gorebridge station, about 1.7 miles east of the centre. Other landmarks nearby include Midlothian Community Hospital (3.2 miles north) and Dalhousie Castle (1.9 miles north). The countryside around Carrington includes Edgelaw Reservoir.

Signs you need fire stopping in Carrington

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.

Things that usually lead to an enquiry:

  • Fire sealant pulled out of the opening
  • Improvised or mixed-product fire seals
  • Damaged fire seals in risers and voids
  • Fire-stopping items raised at inspection or handover

For a hospital such as Midlothian Community Hospital, 3.2 miles to the north of Carrington, penetration sealing is usually phased ward by ward, with infection-control rules agreed first.

How to choose a sealant contractor

Aftercare for building managers

To get the most from the new sealant:

  • Keep product data and details in the fire safety file
  • Keep general-purpose fillers away from compartment walls
  • Agree the fire-stopping specification before services go in
  • Look above ceilings when tiles are lifted for other jobs

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.

Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small; found late, it can be one of many.
