Fire stopping in Pett

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. 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, small duct penetrations where the tested detail allows and linear gaps at wall heads, and the failures we’re asked to look at most are fire-stopping items raised at inspection or handover and expanding foam used as fire stopping. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Pett is the same: the right product in a properly prepared joint.

Around smaller places like Pett, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

How the quote is worked out

The price varies from site to site. Expect it to depend on:

  • Removal of failed or old sealant
  • Induction, permit and paperwork requirements
  • Any access equipment needed
  • Backing rod, priming and other preparation

Pricing service penetrations depends on quantities, condition and access. Ask us for a fixed quote.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • The asbestos register, for older buildings
  • Approximate linear metres or a joint schedule
  • Any specification or named product
  • Anything awkward about access or site hours

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or email a schedule or drawings.

Questions about Pett

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Pett?

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.

Is Pett too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Do you seal on top of existing 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.

When can the area be used after sealing?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Do you guarantee your work?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

How many days will you need on site?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Compartment walls and floors in Pett

In England, Approved Document B covers fire stopping of openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Pett is about 53 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

Wherever services are added at a hospital such as Conquest Hospital (to the west of Pett) the compartment line has to be made good with the specified product. For a building such as St Mary & St Peter, new heating or data runs are the usual reason penetrations need sealing.

Pett is about 5 miles east of Hastings, in East Sussex. If you are looking for fire stopping in Pett, we can help, as we do across East Sussex. 308 places across East Sussex fall within our area, Pett among them. Sites around Brighton have their own page, roughly 35 miles from Pett.

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Pett are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

What we need from you

  • Agree which areas must stay open
  • Share the asbestos register for older buildings
  • Point out parking and an unloading spot

Advice

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Plastic pipes whose detail calls for a collar or wrap
  • Gaps in walls that were never built as compartment walls
  • Approving the work on behalf of building control

If in doubt, phone 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

What we seal

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

What happens if it’s left?

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. One visit to deal with every failing joint makes more sense than several trips to a place like Pett, rather than one at a time. Send photos of each area and we’ll quote for the lot.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Doing it in-house

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

How the job changes by surface

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail.

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.
