Fire stopping in Detling

No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. Most enquiries involve openings left by services added after handover and seals disturbed by maintenance and left open, on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and linear gaps at wall heads. One point of contact handles commercial sealant work in Detling from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Rural conversions around Detling can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or use the quote form and we will come back to it.

Where services cross fire walls in Detling

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. Either way, we install the specified product to its tested detail. Central London is about 32 miles from Detling. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.

Shop fits in centres such as The Mall Maidstone, 2.4 miles to the south-west of Detling, can bring new services through fire-resisting walls between units, which then need the specified seal. Older community buildings such as St Martin of Tours Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Detling is about 3 miles north-east of Maidstone, in Kent. We send applicators to Detling for service penetrations. 931 places across Kent fall within our area, Detling among them. For work in that direction, see our London page (32 miles or so).

Business premises anywhere in ME14 are within our area. Streets here include The Street, Princes Way and Queens Way. Nearby places we also cover include Thurnham (1 mile south-east), Grove Green (1 mile south-west), Harbourland (1 mile west), Weavering (2 miles south) and Bearsted (2 miles south) for service penetrations. Nearby towns on our patch include Maidstone (3 miles south-west), Sittingbourne (8 miles north-east), Gravesend (12 miles north-west), Tonbridge (14 miles south-west), Faversham (14 miles east) and Northfleet (14 miles north-west).

Other landmarks nearby include KIMS hospital (0.8 miles south-west) and The Mall Maidstone (2.4 miles south-west). Not far away are Burham Down and Detling Hill.

What we can’t put right

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Fire doors, dampers or other fire safety equipment
  • Plastic pipes whose detail calls for a collar or wrap

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
  • Joints between fire-resisting walls and floors
  • Pipe penetrations
  • Cable penetrations
  • Service gaps in risers
  • Linear gaps at wall heads

Different surfaces, different methods

Metal pipes

Heat travels along metal pipework. We follow whatever the detail requires and flag anything we can’t match.

Drylining partitions

Drylined fire walls are tested in a particular build-up. We check that the product’s detail covers that partition type and board thickness before sealing.

Doing it in-house

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

From enquiry to sign-off

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. If others near Detling need work, visits can be combined. You will have a fixed quote before work starts.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out.
  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.

What we need from you

  • Arrange parking or a loading space
  • Send any specification or drawings in advance
  • Point out any areas we must not close

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Common questions from Detling clients

Can you work around term dates at a campus such as University for the Creative Arts?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Do you cover business parks and estates near Detling, such as Viewpoint Industrial Estate?

Yes. Estates, retail parks and business parks around Detling, Viewpoint Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

What do BS EN 1366-3 and BS EN 13501-2 mean?

The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. EI 60 means integrity and insulation for 60 minutes in the tested arrangement; installing to the detail is what carries that across to site.

Can you seal any opening with fire-rated sealant?

No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. If an opening falls outside, it needs another solution, as set out by the designer.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

What site paperwork can you supply?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

Will you sign off the seals for us?

No. Sign-off belongs to the designer or building control, not the installer. We will confirm the product and detail installed.

Cost factors for service penetrations

Each job is priced on its own details. The main factors are:

  • Whether old sealant has to be cut out first
  • Working within restricted access windows
  • Which sealant the job calls for
  • Joint width, depth and condition

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Whether the building will be occupied during the work
  • Access details, including height
  • Clear photographs of the problem areas
  • Where the site is, with the postcode

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, call the office on 01277 525 020 or email drawings and photos.

Common problems we fix in Detling

Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.

Common reasons buildings call us in:

  • Openings left by services added after handover
  • Unsealed penetrations discovered above suspended ceilings
  • Expanding foam used as fire stopping
  • Fire seals cut back for extra cables and never reinstated

Where a unit on an estate such as Viewpoint Industrial Estate, which lies west of Detling, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
