About our fire stopping in Marsh Benham

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on service gaps in risers, pipe penetrations and joints between fire-resisting walls and floors, and the failures we are asked to look at most are seals disturbed by maintenance and left open and builders’ foam or ordinary silicone in compartment walls. A single leaking joint is often how a building in Marsh Benham first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Barn and farm-building conversions near places like Marsh Benham often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

After the work

For the best life from the joints:

  • Check with the data sheet before painting over fire sealant
  • Record which product was used where
  • Get seals inspected before ceilings and boxing close
  • Make fire stopping part of every scope that crosses a fire-resisting wall

Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.

Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.

What happens if it’s left?

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. Halls, stores and units around places like Marsh Benham may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Common questions from Marsh Benham clients

Can you take on a job at a hospital such as West Berkshire Community Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

How long before the joints can be used?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

Can you fit around our working hours?

We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a single visit for a short list of penetrations, or a phased programme for a whole building, and our waste is bagged and taken away as we go. For a building around Marsh Benham, tell us how to find it and who will meet us. Send that with the details and we’ll 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. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Have the specification and drawings to hand
  • Warn occupants and staff about the work

Advice

How the job changes by surface

Plastic pipes

Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail.

Metal pipes

Heat travels along metal pipework, and the tested detail may ask for insulation beyond the wall. We follow whatever the detail requires and flag anything we can’t match.

Signs you need fire stopping in Marsh Benham

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.

What tends to prompt an enquiry:

  • Damaged fire seals in risers and voids
  • Unsealed penetrations discovered above suspended ceilings
  • Builders’ foam or ordinary silicone in compartment walls
  • Fire sealant pulled out of the opening

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

What to look for in a quote

  • Health and safety accreditation such as CHAS
  • Whether old or failed sealant will be cut out, not overlaid
  • Their public liability cover
  • Whether primer will be used where the manufacturer specifies it

Our contractor checklist

When something else is needed

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

  • Deciding what a wall or floor needs, which belongs to the designer
  • Issuing fire ratings or certificates for seals
  • Construction that lacks the fire resistance the seal relies on

If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think before you book.

  • Service gaps in risers

  • Pipe penetrations

  • Linear gaps at wall heads

Fire-rated sealing for Marsh Benham buildings

In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Central London is about 56 miles from Marsh Benham. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.

Shop fits on retail sites such as Parkway Shopping Centre (to the east of Marsh Benham) can bring new services through fire-resisting walls between units, to be sealed with the specified product. For a hotel such as The Vineyard Hotel, which lies north-east of Marsh Benham, penetration seals are worth checking after any refit or services upgrade.
