Fire stopping in Pegwell

How we handle fire stopping in Pegwell

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal. We work on joints between fire-resisting walls and floors, cable penetrations and pipe penetrations, and the failures we’re asked to look at most are seals disturbed by maintenance and left open and snag lists that include open service penetrations. Facilities teams, main contractors and managing agents in Pegwell tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Rural conversions around Pegwell can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Gaps in walls that were never built as compartment walls
  • Openings that need collars, wraps, batts or boards rather than sealant

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

Joints and surfaces we work on

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

Looking after the joints

A few simple habits keep the new joints working:

  • Arrange inspection before areas are covered up
  • Ask the designer to confirm details early on refits
  • Brief every trade that openings they make must be sealed
  • File the specified details where the next contractor can find them

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. Then the seal goes in while the area is open.

FAQs: Pegwell

Would you work within a site like Ramsgate General 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.

Do you work in occupied care homes around Pegwell?

Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you cover Pegwell?

Yes. Pegwell is in our area. To discuss a job, ring 01277 525 020 or email drawings and photos.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

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

Diagnose, treat, sign off

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Rural sites near Pegwell may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings
  • Let building users know which areas are affected

Advice

Why deal with it now?

A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail. Older rural buildings around Pegwell move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

A quote for service penetrations depends on how many there are, their condition and the access. Call for a quote.

Where services cross fire walls in Pegwell

At about 65 miles from central London, Pegwell is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls. In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.

Where a unit on an estate such as Old Timber Yard Industrial Estate, 0.9 miles to the north of Pegwell, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. Large healthcare estates like Ramsgate General Hospital (to the east of Pegwell) change their services often, so penetration seals are worth checking after M&E work. Colleges such as Nelson College London, 2.3 miles north of Pegwell, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
