Where services cross fire walls in Holland Park

Fire stopping of openings and penetrations in England falls under Approved Document B. 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. We install whatever has been specified, to the product’s tested detail. The area within 2 miles of Holland Park holds a good number of hotels. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product.

In a retail centre such as Kensington Arcade (0.6 miles east of Holland Park), any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. Office fit-outs on sites such as Berghem Mews Business Village, 0.7 miles south-west of Holland Park, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Holland Park is about 1 mile north of Kensington, in Greater London. We cover commercial sites throughout Holland Park. Holland Park is one of 764 places in Greater London on our list for service penetrations.

Work on service penetrations is covered throughout W8, W11 and W14, whatever the building. Streets here include Dukes Lane, Milson Road and Elsham Road. Main routes into Holland Park include the A402 and A4204, useful when we plan access and materials. Just outside Holland Park, we also work in Kensington (1 mile south), Notting Hill (1 mile north), Shepherd's Bush (1 mile west), Notting Dale (1 mile north) and White City (1 mile north-west). Nearby towns on our patch include London (5 miles east), Marylebone (3 miles east), St Pancras (4 miles north-east), Shoreditch (6 miles east), Walthamstow (10 miles north-east) and Hoxton (6 miles east).

Landmarks near Holland Park

We work on buildings around Kensington Palace Green, Abdus Salam Library and Windsor Castle in Kensington pub, among other places. Nearby too are Kensington School (0.6 miles south-east) and Fox Primary School (under half a mile north-east). The nearest railway station is Kensington Olympia station, about 0.5 miles south-west of the centre. Well-known places in the area include London Museum (0.7 miles east) and St Mary Abbot's Hospital (0.7 miles south-east). Open spaces near Holland Park include Campden Hill and WWT London Wetland Centre.

How we handle fire stopping in Holland Park

A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. If you have fire-stopping items raised at inspection or handover and openings left by services added after handover, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Holland Park it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. Our part is installing the specified fire-rated sealant; tell us what records you need and we’ll confirm with the quote.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What the job involves on each surface

Small ducts

We seal around ducts only within what the tested detail covers. The ductwork, its supports and any dampers are for the ductwork contractor.

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed, and we work within it.

Common questions from Holland Park clients

Would you work within a site like Cromwell Hospital?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can work at a site such as University of Westminster fit around teaching?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Can you fire stop behind the services contractors?

Yes, where there is a specification for those walls and floors. Openings left by new services are among the most common jobs we see and we close them with the specified product.

What about RAMS and site documents?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

How do I request a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

What changes on 2 September 2029?

It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, subject to transitional arrangements. Scotland follows its own Technical Handbook, with clause 2.1.14 covering service penetrations.

Our process

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. All of Greater London is in the ULEZ, and kerbside space in Holland Park 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. We read the specification, drawings or penetration schedule you send.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  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

  • Have the specification and drawings to hand
  • Clear stock, furniture or equipment away from the joints
  • Point out parking and an unloading spot

Work for main contractors and building owners

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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.

Do you need fire stopping in Holland Park?

Openings in fire-resisting walls normally appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.

Most enquiries start with something like this:

  • Fire stopping installed outside its tested range
  • Expanding foam used as fire stopping
  • Fire seals cut back for extra cables and never reinstated
  • Fire-stopping items raised at inspection or handover

For a site team at a college like St Mellitus Theological College, 1 mile south-east of Holland Park, fire-rated sealing is best scheduled after the summer works.

How to choose a sealant contractor

Aftercare for building managers

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Foam or ordinary sealant is never a fire-seal repair
  • Record which product was used where
  • Check with the data sheet before painting over fire sealant
  • Brief every trade that openings they make must be sealed

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned.
