Fire stopping near Stocker's Head

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

Fire stopping in Stocker's Head, done properly

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you are dealing with fire-rated sealant that has cracked or shrunk back and penetration schedules that need working through, we can put it right, whatever the surface. For commercial sealant work in Stocker's Head, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Around smaller places like Stocker's Head, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Signs you need fire stopping in Stocker's Head

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.

Site and facilities staff are often the first to spot these:

  • Fire-rated sealant that has cracked or shrunk back
  • Builders’ foam or ordinary silicone in compartment walls
  • Damaged fire seals in risers and voids
  • Snag lists that include open service penetrations

Schools such as Charing Church of England Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

What your quote should include

  • Who will actually carry out the work
  • How joint depth will be controlled
  • How they’ll work around occupants
  • What level of public liability insurance do they hold?

How to choose a sealant contractor

On site: what to expect

At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. For a building around Stocker's Head, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Point out parking and an unloading spot
  • Have the specification and drawings to hand
  • Let us know about inductions and permits

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Surface by surface

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

Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Quoting for work in Stocker's Head

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • The product specified
  • Phasing around occupants
  • How much existing material needs removing
  • Quantities, in metres or numbers

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Details that help us quote

For an accurate fixed quote, we need to understand the site. Send us:

  • Rough lengths or quantities, or drawings if you have them
  • Any dates the work must fit around
  • Asbestos survey details if the building is older
  • Access details, including height

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or email us.

FAQs: Stocker's Head

Can you produce the fire-stopping design for a job in Stocker's Head?

No. The designer or fire engineer sets the detail and building control accepts it. We install what’s specified, to the product’s tested detail.

Is Stocker's Head off your patch?

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.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

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

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

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

How long does a typical visit take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Central London is about 44 miles from Stocker's Head. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. In England, Approved Document B covers fire stopping of openings and penetrations. 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. Either way, we install the specified product to its tested detail.

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

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Fire doors, dampers or other fire safety equipment
  • Plastic pipes whose detail calls for a collar or wrap
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

What we seal

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