Fire stopping for businesses in Bishopsbourne

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Fire stopping in Bishopsbourne

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and service gaps in risers, and what we are called in for most is non-fire-rated filler around services and fire-rated sealant that has cracked or shrunk back. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Bishopsbourne is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Barn and farm-building conversions near places like Bishopsbourne often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Common questions from Bishopsbourne clients

Is Bishopsbourne too small for you to travel to?

No. Places such as Bishopsbourne are covered as much as the big towns. 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.

Will you work in a care home in Bishopsbourne without moving residents out?

Yes. We work around residents’ routines, a room or two at a time. Noise and disruption are kept to a minimum.

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. We don’t remove asbestos-containing materials.

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. Include photographs or drawings if you have them.

Will you write the fire-stopping specification?

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

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Commercial clients in Bishopsbourne

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Fire stopping around Bishopsbourne: how the place shapes the job

Bishopsbourne has two care or nursing homes no more than 2 miles away. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. In England, Approved Document B covers fire stopping of openings and penetrations. 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. What we install is set by the specification, and it goes in to the tested detail.

Halls and meeting rooms at places like Church of St Mary sometimes gain new services, and any compartment wall crossed needs the specified seal. On a site such as Canterbury Business Park, 0.8 miles to the north-east of Bishopsbourne, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. On a hospital site such as Kent and Canterbury Hospital (3.2 miles north-west of Bishopsbourne), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Bishopsbourne is about 4 miles south-east of Canterbury, in Kent. Anywhere in CT4, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Bishopsbourne is one of 931 places we cover in Kent. Sites around London have their own page, about 56 miles away.

Postcode districts covered here: CT4. If your site is on The Street, Park Lane and Crows Camp Road or close by, send details and we will quote for service penetrations. Nearby places we also cover include Kingston (1 mile south-east), Bridge (1 mile north), Out Elmstead (1 mile south-east), Marley (1 mile south) and Patrixbourne (2 miles north) for service penetrations. Further afield, our area takes in Ashford (13 miles south-west), Canterbury (4 miles north-west), Margate (15 miles north-east), Dover (10 miles south-east), Folkestone (10 miles south) and Ramsgate (14 miles north-east).

Local landmarks in Bishopsbourne

We work on buildings around The Mermaid Inn. For rail, the closest station is Bekesbourne station, roughly 2.2 miles north of the centre. Well-known places in the area include Canterbury Castle (4.1 miles north-west) and Kent and Canterbury Hospital (3.2 miles north-west).

Site staff or a sealant 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.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Bishopsbourne, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  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. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Before we start on site

  • Tell staff and tenants when we’ll be in
  • Send your site hours and access windows
  • Flag any permit to work we’ll need

Request a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or send details through our quote form.

Advice

What sets the cost

What shapes the price:

  • Backing rod, priming and other preparation
  • The total length or number of joints
  • Removal of failed or old sealant
  • The product specified

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Details that help us quote

The more we know, the firmer the quote. Helpful details to send:

  • The asbestos register, for older buildings
  • Photos of the joints, close up and from further back
  • How the joints are reached, and at what height
  • Rough lengths or quantities, or drawings if you have them

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Looking after the joints

After handover, these steps help:

  • Don’t let anyone top up a fire seal with the wrong product
  • Get seals inspected before ceilings and boxing close
  • Flag new cables with no seal around them
  • Put resealing into every M&E and fit-out package

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.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts.

Honest limits

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Plastic pipes whose detail calls for a collar or wrap
  • Signing off or certifying a building’s fire stopping
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

If you’re not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Joints and surfaces we work on

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