Fire stopping for businesses in Hyde Park Estate

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

How the job changes by surface

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance along with any permits your site needs.

Metal pipes

Heat travels along metal pipework. We follow whatever the detail requires and flag anything we can’t match.

Fire stopping for commercial buildings in Hyde Park Estate

No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth 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. We work on joints between fire-resisting walls and floors, pipe penetrations and service gaps in risers, and the failures we’re asked to look at most are head-of-wall gaps with no fire seal and fire sealant pulled out of the opening. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Hyde Park Estate, that means joint design, primers and backing rod as standard.

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.

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

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

General builders and handymen seal joints, but it isn’t their main trade. 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.

Our process

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and we clear our waste as we work. All of Greater London is in the ULEZ, and kerbside space in Hyde Park Estate can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  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. 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.

What we need from you

  • Point out any areas we must not close
  • Share your working hours and any access restrictions
  • Share the asbestos register for older buildings

Advice

Questions we are asked in Hyde Park Estate

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

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Do you take on jobs in Hyde Park Estate 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. We allow for the ULEZ, which covers every borough

Is Hyde Park Estate in your area?

Yes. We cover Hyde Park Estate, and the simplest way to start is to ring 01277 525 020 or use the quote form.

Do you guarantee your work?

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

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Can the sealant be colour-matched?

That depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

What we are called out for in Hyde Park Estate

Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access usually bring them to light.

Common reasons buildings call us in:

  • Damaged fire seals in risers and voids
  • Hidden openings found during inspections
  • Service penetrations left open after M&E works
  • Builders’ foam or ordinary silicone in compartment walls

Shop fits on retail sites such as Brompton Cross District Shopping Centre. (1.4 miles south of Hyde Park Estate) can bring new services through fire-resisting walls between units, to be sealed with the specified product.

Before you book anyone

  • What site paperwork they can supply
  • Whether their applicators hold CSCS cards
  • How the joint faces will be prepared and primed
  • Health and safety accreditation such as CHAS

How to choose a sealant contractor

What we can’t put right

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Construction that lacks the fire resistance the seal relies on
  • Issuing fire ratings or certificates for seals
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

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

Where we work in Hyde Park Estate

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

Compartment walls and floors in Hyde Park Estate

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. What we install is set by the specification, and it goes in to the tested detail. Hyde Park Estate has plenty of hotels close by, all within 2 miles. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

At a college such as London College of Fashion (1.1 miles east of Hyde Park Estate), checking penetration seals after summer M&E works is good practice. At a university such as BPP University (less than half a mile south-west of Hyde Park Estate), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
