Fire stopping in Aylesham, done properly

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and service gaps in risers, and the failures we are asked to look at most are unsealed openings around new pipes and cables and unsealed joints where partitions meet the slab. One point of contact handles commercial sealant work in Aylesham from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Converted and extended buildings around places like Aylesham can mix old and new construction, 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’ll tell you if the detail calls for something other than sealant.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

What we can’t put right

We check first that sealant really is the fix. It isn’t the answer for:

  • Gaps in walls that were never built as compartment walls
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Approving the work on behalf of building control

If in doubt, phone 01277 525 020 or email drawings and photos and we’ll say what we think.

Joints and surfaces we work on

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

Diagnose, treat, sign off

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. If neighbouring businesses or buildings around Aylesham need work too, visits can be combined. Tell us your site hours and we will plan around them.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  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. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • Share your working hours and any access restrictions
  • Let us know about inductions and permits
  • Tell staff and tenants when we’ll be in

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Compartment walls and floors in Aylesham

Aylesham is about 59 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail.

Halls and meeting rooms at places like St Peter sometimes gain new services, and any compartment wall crossed needs the specified seal. Large healthcare estates like St Martins Hospital (to the north-west of Aylesham) change their services often, so penetration seals are worth checking after M&E work.

Aylesham is about 6 miles south-east of Canterbury, in Kent. Anywhere in CT3, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across Kent, 931 places are covered, Aylesham among them. There’s a separate page for London, roughly 59 miles from Aylesham.

If you need fire stopping in CT3, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Among the streets we cover are Market Place, Mexborough Square and Derwent Way. Sites close to Aylesham are covered too, including Bloodden (1 mile north), Adisham (1 mile north), Womenswold (1 mile south-west), Woolage Green (2 miles south) and Out Elmstead (2 miles south-west). A short drive away, we cover Canterbury (6 miles north-west), Margate (13 miles north-east), Dover (8 miles south-east), Folkestone (10 miles south), Ramsgate (12 miles north-east) and Broadstairs (14 miles north-east).

Building owners, agents and FMs in Aylesham

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

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Looking after the joints

Once the work is signed off, these steps help:

  • Treat an open penetration as a priority repair
  • Keep general-purpose fillers away from compartment walls
  • Ask the designer to confirm details early on refits
  • Put resealing into every M&E and fit-out package

Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, so check the product data first.

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned.

Quoting for work in Aylesham

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

  • Quantities, in metres or numbers
  • Specialist products, such as fire-rated or hygienic sealants
  • Site requirements such as inductions and permits
  • The size and state of each joint

Pricing service penetrations depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

What we need to price the job

Whether it’s one area or a whole building, the same details help:

  • Any specification or named product
  • The type of building and who uses it
  • Whether an asbestos survey exists
  • The site address and postcode

For a fixed quote, give us a call on 01277 525 020 or email us, telling us the site location and the nature of the job. You can also send details through our quote form.

Questions we’re asked in Aylesham

What happens to BS 476 references for fire stopping in Aylesham?

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. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Can you work on a hospital site such as St Martins Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

What will the job cost?

It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

Do you offer coloured sealant?

It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Can you work while the building is occupied?

In most cases, yes. Phased work can be planned so areas stay in use.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Signs you need fire stopping in Aylesham

Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe, and the repair is often skipped.

These are often picked up first by site or facilities staff:

  • Unsealed joints where partitions meet the slab
  • Seals disturbed by maintenance and left open
  • Non-fire-rated filler around services
  • Old intumescent sealant that has split away

Industrial units on estates such as Aylesham Industrial Estate (0.5 miles south-west of Aylesham) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.
