Fire stopping in Hackington

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

Fire stopping for commercial buildings in Hackington

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. Most enquiries involve non-fire-rated filler around services and penetration schedules that need working through, on service gaps in risers, linear gaps at wall heads and pipe penetrations. One point of contact handles commercial sealant work in Hackington from the first photos to the final walk-round, for single jobs and planned programmes alike.

Smaller places such as Hackington 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.

We stand by our work with a 12-month guarantee. That covers our preparation and application.

Why it’s worth doing now in Hackington

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, and doing it once, properly, is cheaper. Halls, stores and units around places like Hackington may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

See our cost guide or how we’re accredited.

What we can’t put right

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

  • Writing the fire-stopping specification
  • Reviewing a building’s overall fire safety
  • Openings that need collars, wraps, batts or boards rather than sealant

Not sure which it is? You can call the office on 01277 525 020 or email us and we will tell you honestly.

Where we work in Hackington

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

Signs you need fire stopping in Hackington

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.

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

  • Seals disturbed by maintenance and left open
  • Openings found when ceilings come down for a refit
  • Unsealed openings around new pipes and cables
  • Head-of-wall gaps with no fire seal

Shop fits on retail sites such as Maybrook Retail Park, 1.5 miles south-east of Hackington, can bring new services through fire-resisting walls between units, to be sealed with the specified product.

Questions to ask before you book

  • How long is the guarantee, and what does it include?
  • Will failed sealant be removed rather than covered?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

Hackington: questions and answers

Is Hackington too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Can you take on a job at a hospital such as Saint Martin's Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Is BS 476 being phased out?

From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, subject to the Government’s transitional arrangements. After that, the European classification under BS EN 13501-2 is the route. Your designer will choose products with the right evidence.

Do you approve fire stopping for building control?

No. Sign-off belongs to the designer or building control, not the installer. We will confirm the product and detail installed.

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

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 does an EI 60 rating mean?

Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Results are classified under BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. The rating applies to the product as tested.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

What the job involves on each surface

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork typically needs a different solution set by the designer and we flag that rather than guess.

Plastic pipes

Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough.

Compartments and services around Hackington

At about 52 miles from central London, Hackington is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. There are two care or nursing homes within about 2 miles of Hackington. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail.

At a college such as Canterbury College, which lies south of Hackington, checking penetration seals after summer M&E works is good practice. Wherever services are added at a hospital such as Saint Martin's Hospital, 2.4 miles south-east of Hackington, the compartment line has to be made good with the specified product.

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Hackington can form part of a wider programme.

Our process

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a building around Hackington, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We start with your penetration schedule, drawings or specification.
  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. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  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

  • Have the specification and drawings to hand
  • Agree which areas must stay open
  • Point out parking and an unloading spot
