What the job involves on each surface

Small ducts

We seal around ducts only within what the tested detail covers. The ductwork, its supports and any dampers are for the ductwork contractor.

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, though larger ones usually call for a collar or wrap. We check the pipe material and diameter against the detail before we start.

Fire stopping for commercial buildings in Tonge Corner

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. We work on cable penetrations, service gaps in risers and linear gaps at wall heads, and the usual reasons a site gets in touch are unsealed openings around new pipes and cables and unsealed joints where partitions meet the slab. For commercial sealant work in Tonge Corner, you deal with one contact from quote to sign-off, whether it’s one building or several.

Rural conversions around Tonge Corner can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Leave it or put it right?

An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first. For buildings around smaller places like Tonge Corner, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The price depends on the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

General trades versus a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Cost factors for service penetrations

Quotes vary with the job. Expect it to depend on:

  • The site’s rules and procedures
  • How much there is to seal
  • Working within restricted access windows
  • Which sealant the job calls for

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 you will have a fixed figure to work with.

Sending details for a quote

To price the job accurately, we need to understand the site. Send us:

  • Whether the building will be occupied during the work
  • Any dates the work must fit around
  • The asbestos register, for older buildings
  • Specification clauses that apply

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

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. For work around Tonge Corner, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  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. Foam, ordinary sealant and debris come out.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Tell us your opening times and when work is allowed
  • Tell staff and tenants when we’ll be in

Advice

Tonge Corner: questions and answers

Will you plan work around the academic year at somewhere like KITE College?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Tonge Corner?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

Can the sealant be colour-matched?

That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Are you CHAS accredited?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

What will the job cost?

Each job is quoted on its own details. To get one, speak to us on 01277 525 020 or email us with a description of the work.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Compartments and services around Tonge Corner

Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. At about 39 miles from central London, Tonge Corner is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

For a school such as Lansdowne Primary School, penetration sealing fits best at the end of the summer works. Hotels like Tonge Barn Hotel (to the south of Tonge Corner) are refurbished in phases, and each phase can open up compartment walls.

Signs you need fire stopping in Tonge Corner

When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.

What tends to prompt an enquiry:

  • Hidden openings found during inspections
  • Seals disturbed by maintenance and left open
  • Seals that don’t match their tested detail
  • Fire sealant pulled out of the opening

Large healthcare estates like Sittingbourne Memorial Hospital (1.9 miles west of Tonge Corner) change their services often, so penetration seals are worth checking after M&E work.
