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

Questions we are asked in Swinbrook

Is Swinbrook off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How does the move away from BS 476 affect penetration seals in Swinbrook?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Can staff carry on working while you are here?

Normally, yes. We phase the work so most of the building stays in use.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Fire stopping in Swinbrook

Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind. Those on your schedule are closed with the specified product. We work on joints between fire-resisting walls and floors, service gaps in risers and linear gaps at wall heads, and the usual reasons a site gets in touch are service penetrations left open after M&E works and fire stopping installed outside its tested range. For commercial sealant work in Swinbrook, you deal with one contact from quote to sign-off, whether it’s one building or several.

Rural conversions around Swinbrook can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

On site: what to expect

Before we leave any area, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Swinbrook may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Before we start on site

  • Agree which areas must stay open
  • Tell us your opening times and when work is allowed
  • Send any specification or drawings in advance

Getting a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Aftercare for building managers

Regular inspection catches problems early. Specifically:

  • Have penetrations checked while they can still be seen
  • Put resealing into every M&E and fit-out package
  • Include service cupboards in routine inspections
  • Check with the data sheet before painting over fire sealant

New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.

When to bring in a specialist

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

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.

Surface by surface

Metal pipes

Heat travels along metal pipework, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.

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, so we check before sealing.

Do you need fire stopping in Swinbrook?

Damage plays a part too. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped, and the repair is often skipped.

Look out for the following:

  • Unsealed joints where partitions meet the slab
  • Seals that don’t match their tested detail
  • Non-fire-rated filler around services
  • Fire-rated sealant that has cracked or shrunk back

In a building such as Church of St Mary, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Comparing quotes

  • Will failed sealant be removed rather than covered?
  • Are they CHAS accredited or on Constructionline?
  • Proof of insurance
  • Do they follow the manufacturer’s priming guidance?

Our contractor checklist

When something else is needed

Part of a good diagnosis is knowing where sealant stops. 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
  • Fire risk assessments, a job for a competent assessor
  • Walls or floors that aren’t fire-resisting to begin with

Not sure which it is? You can phone 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Penetration seals near Swinbrook

The area within 2 miles of Swinbrook holds a number of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.

In a school such as Burford School, fire-rated sealant goes in around service penetrations where it is specified. Offices at parks like Wychwood Business Centre, 2.9 miles north of Swinbrook, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.
