Common questions from Payden Street clients

Is a smaller place like Payden Street outside your area?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

What happens to BS 476 references for fire stopping in Payden Street?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.

Is your workmanship covered by a guarantee?

Yes. Workmanship is guaranteed for 12 months on every job.

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.

How many days will you need on site?

That varies with the scale of the job, but the work typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For bigger or phased jobs, we will set out a timescale with the quote.

Fire stopping for commercial buildings in Payden Street

Facilities managers in Payden Street often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it. Where there isn’t one, the designer or fire engineer needs to set one first. We work on pipe penetrations, small duct penetrations where the tested detail allows and service gaps in risers, and what we are called in for most is seals that don’t match their tested detail and damaged fire seals in risers and voids. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Payden Street, preparation and product choice get the time they need.

Around smaller places like Payden Street, 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.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Signs you need fire stopping in Payden Street

Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run 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.

Things that usually lead to an enquiry:

  • Non-fire-rated filler around services
  • Fire stopping installed outside its tested range
  • Hidden openings found during inspections
  • Open linear gaps along the top of fire-resisting walls

For a building such as Church of St Margaret, new heating or data runs are the usual reason penetrations need sealing.

What your quote should include

  • Health and safety accreditation such as CHAS
  • Proof of insurance
  • How the existing material will be dealt with
  • The named product and why it was chosen

How to choose a sealant contractor

Site staff or a sealant specialist?

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.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

What affects the price in Payden Street

Your fixed quote is built from the real scope. It allows for:

  • Site requirements such as inductions and permits
  • The total length or number of joints
  • Distance, for remote addresses
  • The size and state of each joint

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Send us:

  • Anything awkward about access or site hours
  • Your programme or deadline
  • Where the site is, with the postcode
  • What the building is and how it’s used

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email the details over.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:

  • Gaps in walls that were never built as compartment walls
  • Plastic pipes whose detail calls for a collar or wrap
  • Reviewing a building’s overall fire safety

Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Payden Street, 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. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  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. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Send your site hours and access windows
  • Warn occupants and staff about the work
  • Move anything stored against the joints

Compartment walls and floors in Payden Street

Central London is about 40 miles from Payden Street. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. For England, the fire stopping of penetrations is dealt with in 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. Our part stays the same: the specified product, installed to its tested detail.

Holiday works at schools like The Lenham School often leave service openings to seal before pupils return. For an estates team at a campus like Canterbury Christ Church University (3.3 miles west of Payden Street), summer M&E works are usually followed by a round of penetration sealing.

Maintenance after handover

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Look above ceilings when tiles are lifted for other jobs
  • Agree the fire-stopping specification before services go in
  • Treat an open penetration as a priority repair
  • Don’t let anyone top up a fire seal with the wrong product

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown, and report them promptly.

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