Fire stopping for businesses in Kippington

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

Honest limits

Honesty saves time and money. New sealant won’t cure:

  • Approving the work on behalf of building control
  • Construction that lacks the fire resistance the seal relies on
  • Large openings beyond what any sealant detail covers

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

What we seal

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

Fire stopping in Kippington

No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths 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. If you are dealing with fire-stopping items raised at inspection or handover and damaged fire seals in risers and voids, we can help, whatever the surface. Looking for mastic applicators who cover Kippington? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

Around smaller places like Kippington, many commercial buildings are conversions or extensions of older ones, so the wall or floor a service passes through isn’t always what the drawings assume. The right product depends on the wall or floor and the services passing through, and we will tell you if the detail calls for something other than sealant.

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

Different surfaces, different methods

Drylining partitions

Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do.

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.

FAQs: Kippington

Do you work on fire-rated sealing in hotels in Kippington?

Yes. We install fire-rated and intumescent sealant where it is specified. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.

How does the move away from BS 476 affect penetration seals in Kippington?

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. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Is your workmanship covered by a guarantee?

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

Can you work while the building is occupied?

In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

What will the job cost?

There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.

Site staff or a sealant specialist?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

On site: what to expect

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. For a job in Kippington, the main thing is a clear picture of the work, so send photographs of each area. A fixed quote follows.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  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.

Preparing the site

  • Point out parking and an unloading spot
  • For older buildings, check the asbestos register before work
  • Let us know about inductions and permits

Building owners, agents and FMs in Kippington

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Kippington can form part of a wider programme.

Common problems we fix in Kippington

Openings in fire-resisting walls usually appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.

Clients normally get in touch after noticing one or more of the following:

  • Damaged fire seals in risers and voids
  • Openings left by services added after handover
  • Snag lists that include open service penetrations
  • Open linear gaps along the top of fire-resisting walls

In a building such as Church of St Mary, any service penetration through a fire-resisting wall should be sealed to the specified detail.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • The terms of the workmanship guarantee
  • Will CSCS-carded applicators be on site?
  • Will RAMS and insurance details be available?

How to choose a sealant contractor

Compartment walls and floors in Kippington

Kippington lies roughly 20 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. 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. Either way, we install the specified product to its tested detail.

On a hospital site such as Sevenoaks Hospital, 1.4 miles to the north-east of Kippington, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. For a school such as St Thomas' Catholic Primary School, penetration sealing fits best at the end of the summer works.
