How we handle fire stopping in Temple

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on pipe penetrations, service gaps in risers and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are hidden openings found during inspections and openings left by services added after handover. A specialist sealant contractor works differently from a general builder: on jobs in Temple, preparation and product choice get the time they need.

Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. Our part is installing the specified fire-rated sealant; tell us what records you need and we’ll confirm with the quote.

Every job we finish is backed by a 12-month workmanship guarantee, in Temple as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Our process

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. All of Greater London is in the ULEZ, and kerbside space in Temple can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. First we go through the drawings, schedule or specification for the seals.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Send your site hours and access windows
  • Send any specification or drawings in advance
  • Flag any permit to work we will need

Advice

Temple: questions and answers

Do you take on jobs in Temple where loading and access are tightly controlled?

Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for

Can you work on a hospital site such as St Bartholomew's Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is any job too small?

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

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you guarantee your work?

Yes. Our workmanship is backed for 12 months.

Cost factors for service penetrations

What shapes the price:

  • The size and state of each joint
  • Any access equipment needed
  • Which sealant the job calls for
  • How much there is to seal

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

What we need to price the job

Good information means a firmer quote. When you get in touch, include:

  • Anything awkward about access or site hours
  • What the building is and how it’s used
  • Clear photographs of the problem areas
  • Where the site is, with the postcode

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

Common problems we fix in Temple

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

Clients usually get in touch after noticing something like this:

  • Fire-rated sealant that has cracked or shrunk back
  • Fire seals cut back for extra cables and never reinstated
  • Openings left by services added after handover
  • Unsealed joints where partitions meet the slab

Colleges such as The Royal College of Radiologists, less than half a mile north-west of Temple, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Questions to ask before you book

  • How they’ll work around occupants
  • Health and safety accreditation such as CHAS
  • The terms of the workmanship guarantee
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Questions to ask before you appoint anyone

What the job involves on each surface

Plastic pipes

Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail, and we will never swap a specified collar for sealant.

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we’ll say if that applies.

Compartments and services around Temple

The area within 2 miles of Temple holds plenty of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. 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.

For an estates team at a campus like King's College London, less than half a mile to the west of Temple, summer M&E works are usually followed by a round of penetration sealing. Industrial units on estates such as Grand Vitesse Industrial Estate, 0.7 miles south-east of Temple, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

Temple is about 1 mile south of St Pancras, in City of London. We cover Temple and the rest of City of London, with the same fixed quotes and 12-month guarantee as everywhere else. Our City of London coverage takes in 7 places.

We cover the SE1, WC2H and WC2B postcode districts. If your site is on Shoe Lane, Drury Lane and New Square or close by, we can quote for service penetrations. Temple sits on or close to the A4 and A40. Just outside Temple, we also work in Temple Bar (1 mile north), Blackfriars (1 mile east), Aldwych (1 mile west), Clare Market (1 mile north-west) and Covent Garden (1 mile west).
