About our fire stopping in Tolleshunt Knights

No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. We work on joints between fire-resisting walls and floors, cable penetrations and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are builders’ foam or ordinary silicone in compartment walls and unsealed openings around new pipes and cables. One point of contact handles commercial sealant work in Tolleshunt Knights from the first photos to the final walk-round, for single jobs and planned programmes alike.

For a smaller site near Tolleshunt Knights, we plan to do all the penetrations in one go, with the specification and photos sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sets the cost

What shapes the price:

  • The site’s rules and procedures
  • How much existing material needs removing
  • Specialist products, such as fire-rated or hygienic sealants
  • Quantities, in metres or numbers

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Sending details for a quote

However big the job, these details speed things up:

  • How the joints are reached, and at what height
  • Specification clauses that apply
  • Clear photographs of the problem areas
  • Whether the building will be occupied during the work

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Gaps in walls that were never built as compartment walls
  • Fire risk assessments, a job for a competent assessor
  • Openings that need collars, wraps, batts or boards rather than sealant

Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

What we seal

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

Where services cross fire walls in Tolleshunt Knights

Central London is about 43 miles from Tolleshunt Knights. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need 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. Either way, we install the specified product to its tested detail.

Offices at parks like Beckingham Business Park (2.6 miles south of Tolleshunt Knights) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. In a building such as Church of All Saints, any service penetration through a fire-resisting wall should be sealed to the specified detail.

How a job runs

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For work around Tolleshunt Knights, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Before we start on site

  • Explain the parking and delivery arrangements
  • Agree which areas must stay open
  • Make sure the joints can be reached

FAQs: Tolleshunt Knights

Does your area include sites such as Beckingham Business Park, near Tolleshunt Knights?

Yes. We cover Tolleshunt Knights and the area around it, including industrial estates, business parks and retail parks such as Beckingham Business Park. A few photographs and the unit address let us price the work.

Is Tolleshunt Knights too far out for you?

Not at all. Tolleshunt Knights is within our area. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you approve fire stopping for building control?

No. Approval sits with the designer, principal designer or building control. We’ll confirm the product and detail installed and agree any further records when we quote.

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Do you guarantee your work?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Different surfaces, different methods

Drylining partitions

Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range and we’ll tell you what the detail says instead.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically and tell you about openings outside the list.

When to call us in Tolleshunt Knights

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls.

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

  • Fire seals cut back for extra cables and never reinstated
  • Unsealed joints where partitions meet the slab
  • Fire-rated sealant that has cracked or shrunk back
  • Hidden openings found during inspections

In a school such as St Luke's Church of England Controlled Primary School, fire-rated sealant goes in around service penetrations where it is specified.

What to look for in a quote

  • The terms of the workmanship guarantee
  • How the joint faces will be prepared and primed
  • Will RAMS and insurance details be available?

Questions to ask before you appoint anyone

Maintenance after handover

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

  • Don’t let anyone top up a fire seal with the wrong product
  • Settle who seals which penetrations at the start of a project
  • Put resealing into every M&E and fit-out package
  • Treat an open penetration as a priority repair

New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.

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