Fire stopping for Hothfield sites

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

How we handle fire stopping in Hothfield

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. If you are dealing with unsealed joints where partitions meet the slab and snag lists that include open service penetrations, we can help. Most enquiries from Hothfield start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Smaller places such as Hothfield still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

What we’re called out for in Hothfield

Plenty of openings were simply never closed. Inspections, refurbishments and ceiling access usually bring them to light.

Most enquiries start with something like this:

  • Unsealed penetrations discovered above suspended ceilings
  • Unsealed joints where partitions meet the slab
  • Builders’ foam or ordinary silicone in compartment walls
  • Snag lists that include open service penetrations

Halls and meeting rooms at places like Church of St Margaret sometimes gain new services, and any compartment wall crossed needs the specified seal.

Before you book anyone

  • Proof of insurance
  • What the guarantee covers, and for how long
  • Are they CHAS accredited or on Constructionline?
  • How they handle RAMS and site documents

Questions to ask before you appoint anyone

Fire stopping around Hothfield: what changes locally

In England, Approved Document B covers fire stopping of openings and penetrations. 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. What we install is set by the specification, and it goes in to the tested detail. Hothfield is about 46 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.

For a unit at a centre such as Warren Retail Park, which lies east of Hothfield, penetration seals are worth checking after each shop fit. At a college such as Ashford College (2.9 miles south-east of Hothfield), checking penetration seals after summer M&E works is good practice.

Hothfield is about 3 miles north-west of Ashford, in Kent. Looking for fire stopping in Hothfield? We can help, as we do across Kent. Hothfield is one of 931 places we cover in Kent for service penetrations. We also cover London, some 46 miles away.

Work on service penetrations is covered throughout TN26, for business premises of every kind. For a building on The Street, Sackville Close and Beech Drive or nearby, send details and we will quote for service penetrations. Sites close to Hothfield are covered too, including Tutt Hill (1 mile north), Ram Lane (1 mile north), Potters Corner (1 mile east), Westwell Leacon (2 miles north) and Godinton (2 miles south-east). Bigger towns within reach include Maidstone (14 miles north-west), Ashford (3 miles south-east), Canterbury (14 miles north-east), Sittingbourne (12 miles north), Faversham (10 miles north) and Hythe (13 miles south-east).

Around Hothfield

For rail, the closest station is Charing station, roughly 2.9 miles north-west. Well-known places in the area include County Square (2.7 miles south-east) and William Harvey Hospital (4.6 miles south-east).

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • Induction, permit and paperwork requirements
  • How accessible the joints are
  • Removal of failed or old sealant
  • Working within restricted access windows

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

What we need to price the job

It doesn’t need to be a full survey. A few details are enough to get going:

  • The type of building and who uses it
  • Anything awkward about access or site hours
  • Clear photos of the problem areas
  • Approximate linear metres or a joint schedule

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or send photos by email.

General trades versus a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

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.

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Hothfield are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out.
  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.

Preparing the site

  • Flag any permit to work we will need
  • Arrange parking or a loading space
  • Send any specification or drawings in advance

Request a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Common questions from Hothfield clients

Is a smaller place like Hothfield outside your area?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

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

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.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

How much does the work cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Surface by surface

Cables and cable bundles

Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe, and some details add wrapping or a set length of insulation. If the detail needs something beyond sealant, we tell you.
