Fire stopping for Crouch sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle fire stopping in Crouch

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. So our job is to reproduce that arrangement faithfully. Site teams most often ask us about improvised or mixed-product fire seals and hidden openings found during inspections, across joints between fire-resisting walls and floors, service gaps in risers and pipe penetrations. Looking for mastic applicators who cover Crouch? We’ve been sealing commercial buildings since 2005.

A job near Crouch is usually planned around one visit, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Keeping the joints sound

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

  • Put resealing into every M&E and fit-out package
  • Treat an open penetration as a priority repair
  • Don’t let anyone top up a fire seal with the wrong product
  • Get seals inspected before ceilings and boxing close

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.

Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.

How the job changes by surface

Cables and cable bundles

Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.

Plastic pipes

Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough.

Questions we’re asked in Crouch

What happens to BS 476 references for fire stopping in Crouch?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Can you work on a hospital site such as Sevenoaks Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Is your workmanship covered by a guarantee?

Yes. Our workmanship is backed for 12 months.

Do you cover Crouch?

Yes. We cover Crouch, and you can call 01277 525 020 or send details through our quote form to get started.

How soon can the area be used again?

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

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.

Penetration seals near Crouch

Central London is about 23 miles from Crouch. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. The area within 2 miles of Crouch holds a number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

In a building such as Church of St Mary, any service penetration through a fire-resisting wall should be sealed to the specified detail. Offices at parks like Bourne Enterprise Centre, 1.2 miles north of Crouch, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. For a school such as Borough Green Primary School, penetration sealing fits best at the end of the summer works.

Crouch is about 6 miles east of Sevenoaks, in Kent. Our applicators travel to Crouch for work on service penetrations, handled exactly as we handle every other area. Our Kent coverage takes in 931 places. We also cover London, around 23 miles from Crouch.

Should maintenance staff do it?

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. Smaller jobs around Crouch can be grouped with others nearby. You’ll have a fixed quote before work starts.

  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. Unsuitable material is removed and the opening cleaned first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Preparing the site

  • Flag any permit to work we’ll need
  • Point out any areas we must not close
  • Explain the parking and delivery arrangements

Advice

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Fire doors, dampers or other fire safety equipment
  • Gaps in walls that were never built as compartment walls
  • Openings that need collars, wraps, batts or boards rather than sealant

If you are not sure, just give us a call on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Surfaces we seal

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