Fire stopping for Bowes Park sites

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

How the quote is worked out

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Travel to remote or island sites
  • The site’s rules and procedures
  • How much existing material needs removing
  • How accessible the joints are

The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you’re ready.

What we need to price the job

We can often quote from photos and a few details. It helps to include:

  • Approximate linear metres or a joint schedule
  • A wide shot and a close-up of the area
  • The site address and postcode
  • Anything awkward about access or site hours

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Fire stopping in Bowes Park, done properly

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls. Those on your schedule are closed with the specified product. Most enquiries involve seals that don’t match their tested detail and service penetrations left open after M&E works, on small duct penetrations where the tested detail allows, pipe penetrations and service gaps in risers. Most enquiries from Bowes Park start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you will hear it from us.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

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 one of these:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Gaps in walls that were never built as compartment walls
  • Issuing fire ratings or certificates for seals

Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Surfaces we seal

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

Penetration seals near Bowes Park

The area within 2 miles of Bowes Park holds a good number of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. We install fire-rated sealant where it is specified and work within the building manager’s permit system.

At a university such as American University in London, which lies south of Bowes Park, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. Theatres, wards and plant rooms at sites like St Ann's Hospital, 1.8 miles south-east of Bowes Park, all have compartment walls crossed by services.

How a job runs

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Preparing the site

  • Send your site hours and access windows
  • Explain the parking and delivery arrangements
  • Warn occupants and staff about the work

Related advice

Different surfaces, different methods

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in, along the full length of the run.

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance along with any permits your site needs.

Do you need fire stopping in Bowes Park?

Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. They come to light during inspections, refits or when another trade lifts a tile.

Any of the following is a good reason to get the joints checked over:

  • Old intumescent sealant that has split away
  • Open linear gaps along the top of fire-resisting walls
  • Fire-stopping items raised at inspection or handover
  • Service penetrations left open after M&E works

For a unit at a centre such as The Mall Wood Green (0.5 miles south-east of Bowes Park), penetration seals are worth checking after each shop fit.

What your quote should include

  • How they handle RAMS and site documents
  • Do they follow the manufacturer’s priming guidance?
  • Their pre-qualification and accreditations
  • What level of public liability insurance do they hold?

Choosing a commercial sealant contractor

Questions we’re asked in Bowes Park

Is a hospital such as St Ann's Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Will you plan work around the academic year at somewhere like American University in London?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

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

No, and we’d rather be clear about that. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.

Do you design or specify fire stopping?

No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do the same rules apply to fire stopping in Scotland?

Building standards in Scotland are separate from England’s, while England relies on Approved Document B. Wherever the site is, our work follows the specification and the tested detail.

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.

For managing agents and facilities managers

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
