Fire stopping for West Cliffe sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Fire stopping in West Cliffe

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. The enquiries we see most involve unsealed penetrations discovered above suspended ceilings and openings left by services added after handover, on service gaps in risers, joints between fire-resisting walls and floors and pipe penetrations. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in West Cliffe it comes down to the same thing: the right product in a properly prepared joint.

Around smaller places like West Cliffe, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Settle who seals which penetrations at the start of a project
  • Brief every trade that openings they make must be sealed
  • Record which product was used where
  • Foam or ordinary sealant is never a fire-seal repair

During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged and get them dealt with.

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

Different surfaces, different methods

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.

Metal pipes

Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.

On site: what to expect

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For work around West Cliffe, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  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. 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.

What we need from you

  • Confirm the product named in the specification
  • Point out any areas we must not close
  • Clear stock, furniture or equipment away from the joints

What we can’t put right

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

  • Deciding what a wall or floor needs, which belongs to the designer
  • Reviewing a building’s overall fire safety
  • Signing off or certifying a building’s fire stopping

Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Where services cross fire walls in West Cliffe

At about 67 miles from central London, West Cliffe is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. The area within 2 miles of West Cliffe holds a number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

At a healthcare site like Royal Victoria Hospital (2.8 miles south-west of West Cliffe), new services through compartment walls are a constant, and each needs the specified seal. Hotels such as St. Margaret's Bay Hotel (to the south-east of West Cliffe) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. Older community buildings such as Church of St Peter that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Why it’s worth doing now in West Cliffe

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is normally a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Around West Cliffe, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Common questions from West Cliffe clients

Is West Cliffe too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Would you work within a site like Royal Victoria Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you hold third-party fire-stopping installer certification?

No. We don’t hold a third-party fire-stopping installer certificate. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. If your contract requires third-party installer certification, we are not the right fit for that package.

Will fire-rated sealant work on every penetration?

No. A sealant’s evidence covers set services, gaps and wall or floor types. If an opening falls outside, it needs another solution.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Is colour matching possible?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

What do you charge?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.
