Fire stopping for businesses in Flishinghurst

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Your questions answered

Is Flishinghurst too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you work at a site such as Hartley Dyke Business Centre, by Flishinghurst?

Yes, sites like Hartley Dyke Business Centre are within our area, along with the rest of Flishinghurst. A few photographs and the unit address let us price the work.

Will you write the fire-stopping specification?

No. The specification comes from your designer, fire engineer or building control. Our role is installing what they specify, to the product’s tested detail.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Fire stopping in Flishinghurst, done properly

It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance in Flishinghurst and nearby. We work on small duct penetrations where the tested detail allows, service gaps in risers and cable penetrations, and what we’re called in for most is fire seals cut back for extra cables and never reinstated and openings left by services added after handover. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Flishinghurst is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller places such as Flishinghurst still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Whoever the client is, the cover is the same: 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.

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Looking after the joints

Once the work is signed off, a little attention goes a long way:

  • Settle who seals which penetrations at the start of a project
  • Leave fire sealant to cure fully before covering it
  • Look above ceilings when tiles are lifted for other jobs
  • Keep general-purpose fillers away from compartment walls

Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original unless the designer specifies otherwise.

Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.

Diagnose, treat, sign off

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Flishinghurst, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  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. 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

  • Confirm the product named in the specification
  • Share your working hours and any access restrictions
  • Point out parking and an unloading spot

Getting a fixed quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or send details through our quote form.

Different surfaces, different methods

Linear joints

Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.

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.

What affects the price in Flishinghurst

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

  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints
  • Phasing around occupants
  • Backing rod, priming and other preparation

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

Sending details for a quote

We can often quote from photos and a few details. Please tell us:

  • A wide shot and a close-up of the area
  • Asbestos survey details if the building is older
  • What the building is and how it’s used
  • How the joints are reached, and at what height

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Honest limits

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Walls or floors that aren’t fire-resisting to begin with
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Fire doors, dampers or other fire safety equipment

Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we will tell you honestly.

Surfaces we seal

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

Penetration seals near Flishinghurst

A number of hotels sit less than 2 miles from Flishinghurst. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. 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.

For a building at a site such as Hartley Dyke Business Centre, which lies south of Flishinghurst, a check of penetration seals after each fit-out is good practice. In a hotel such as Kennel Holt Country House Hotel, 0.7 miles to the east of Flishinghurst, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. In a school such as Colliers Green Church of England Primary School, fire-rated sealant goes in around service penetrations where it is specified.
