Fire stopping in Paddock

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

Why deal with it now?

Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. For buildings around smaller places like Paddock, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What you get with us

  • Old sealant cut out, never sealed over
  • One contact handling all your sites
  • Work to your specification and the manufacturer’s guidance
  • Our applicators hold CSCS cards

Fire stopping for commercial buildings in Paddock

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. Most enquiries involve fire sealant pulled out of the opening and unsealed penetrations discovered above suspended ceilings, across pipe penetrations, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows. One point of contact handles commercial sealant work in Paddock from the first photos to the final walk-round, whether it’s one building or several.

A job near Paddock is usually planned around one visit, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Service penetrations in Paddock buildings

For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Paddock is about 45 miles from central London. 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.

Schools such as Challock Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Large healthcare estates like William Harvey Hospital (5.8 miles south-east of Paddock) change their services often, so penetration seals are worth checking after M&E work.

Paddock is about 5 miles north of Ashford, in Kent. Commercial clients in Paddock use us for work on service penetrations. Across Kent, 931 places are covered, including Paddock. London is covered too, around 45 miles from Paddock.

We cover the TN25 postcode districts for service penetrations. Streets here include Canterbury Road and Green Lane. Nearby places we also cover include Challock (1 mile east), Pested (1 mile north-east), Stocker's Head (2 miles west), Charing Hill (2 miles west) and Stalisfield (3 miles north-west) for service penetrations. Nearby towns on our patch include Maidstone (15 miles west), Ashford (5 miles south), Canterbury (11 miles north-east), Sittingbourne (10 miles north-west), Whitstable (12 miles north-east) and Faversham (7 miles north).

Around Paddock

Around Paddock, our work takes us to commercial buildings near The Chequers pub and The Hayesbrook School and the streets around them.

Different surfaces, different methods

Risers and ceiling voids

Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically and tell you about openings outside the list.

Small ducts

We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.

What we can’t put right

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Walls or floors that aren’t fire-resisting to begin with
  • Reviewing a building’s overall fire safety
  • Approving the work on behalf of building control

If you’re not sure, just call 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Where we work in Paddock

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

FAQs: Paddock

Is Paddock too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

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

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Can one quote cover more than one building?

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

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

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.

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking anything from one day to a planned run of visits, depending on the number of seals and the access. For a building around Paddock, 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 ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Arrange parking or a loading space
  • Flag any permit to work we’ll need
  • Share the asbestos register for older buildings

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

General trades versus a specialist

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Signs you need fire stopping in Paddock

Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped.

Look out for the following:

  • Open linear gaps along the top of fire-resisting walls
  • Old intumescent sealant that has split away
  • Openings left by services added after handover
  • Fire stopping installed outside its tested range

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

Before you book anyone

  • Their approach to joint depth and backing
  • Will RAMS and insurance details be available?
  • Is the sealant right for the movement and the substrate?
  • Are they CHAS accredited or on Constructionline?
