Fire stopping in Nonington

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Signing off or certifying a building’s fire stopping

Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly before you book.

What we seal

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

Fire stopping in Nonington, done properly

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance in Nonington and nearby. If you are dealing with penetration schedules that need working through and unsealed openings around new pipes and cables, we can put it right, on linear gaps at wall heads, joints between fire-resisting walls and floors and service gaps in risers alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Nonington, preparation and product choice get the time they need.

For a smaller site near Nonington, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Do you need fire stopping in Nonington?

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. Across several fit-outs, the openings add up.

If one of these sounds familiar, it’s time for a closer look:

  • Non-fire-rated filler around services
  • Fire-rated sealant that has cracked or shrunk back
  • Head-of-wall gaps with no fire seal
  • Openings left by services added after handover

Older community buildings such as Church of St Mary that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

  • What site paperwork they can supply

Questions to ask before you appoint anyone

Owners, agents and contractors

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Nonington can sit alongside others in a wider programme across Kent.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Different surfaces, different methods

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers.

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, so we check each one.

Where services cross fire walls in Nonington

Nonington lies roughly 60 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Fire stopping of openings and penetrations in England falls under 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. Our part stays the same: the specified product, installed to its tested detail.

For a unit at a site such as Aylesham Industrial Estate (1.5 miles west of Nonington), new power or data runs between office and warehouse can breach a compartment wall. Schools such as Nonington Church of England Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Nonington is about 7 miles north-west of Dover, in Kent. Nonington sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 931 places across Kent fall within our area, including Nonington.

On site: what to expect

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a building around Nonington, 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 start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Getting the site ready

  • Point out any areas we must not close
  • Tell us what induction or permit system the site runs
  • Point out parking and an unloading spot

Get a fixed quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Common questions from Nonington clients

What does the BS 476 change mean for fire-rated sealant in Nonington?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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.

Is Nonington too small for you to travel to?

Not at all. Nonington is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

What will the job cost?

We don’t publish prices, as every site differs. Send photos or drawings and we will price it at a fixed figure.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

When is resealing likely to be due?

There isn’t a single answer, 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.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

How many days will you need on site?

The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.

Why deal with it now?

A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product. Around Nonington, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.

Pricing service penetrations depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.
