Fire stopping for businesses in Martyr's Green

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

Fire stopping in Martyr's Green

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail, not a rule of thumb. If you’re dealing with seals disturbed by maintenance and left open and fire sealant pulled out of the opening, we can help. Facilities teams, main contractors and managing agents in Martyr's Green tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

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

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

From enquiry to sign-off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. Smaller jobs around Martyr's Green can be grouped with others nearby. A fixed quote is given before anything starts.

  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 so the seal starts clean.
  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

  • Tell us your opening times and when work is allowed
  • Point out parking and an unloading spot
  • Send asbestos survey details if the building is pre-2000

Aftercare for building managers

Regular inspection catches problems early. Specifically:

  • Flag new cables with no seal around them
  • Don’t let anyone top up a fire seal with the wrong product
  • Record which product was used where
  • Arrange inspection before areas are covered up

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged, and report them promptly.

Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.

Compartments and services around Martyr's Green

At about 20 miles from central London, Martyr's Green is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

In a hotel such as The Hautboy Hotel, 0.9 miles to the west of Martyr's Green, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

Questions about Martyr's Green

Can you work on a hospital site such as Cobham Community Hospital and Health Centre?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Martyr's Green off your patch?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

What will the job cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

How do you deal with asbestos in old sealant?

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. We don’t remove asbestos-containing materials.

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

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

How the job changes by surface

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement, along the full length of the run.

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail. We check the pipe material and diameter against the detail before we start.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Walls or floors that aren’t fire-resisting to begin with
  • Fire risk assessments, a job for a competent assessor
  • Issuing fire ratings or certificates for seals

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

What we seal

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

When to call us in Martyr's Green

Plenty of openings were simply never closed. They come to light during inspections, refits or when another trade lifts a tile.

It’s worth sending us details if you spot any of the following:

  • Fire seals cut back for extra cables and never reinstated
  • Service penetrations left open after M&E works
  • Fire-stopping items raised at inspection or handover
  • Openings found when ceilings come down for a refit

Large healthcare estates like Cobham Community Hospital and Health Centre, 2.5 miles north-east of Martyr's Green, change their services often, so penetration seals are worth checking after M&E work.

Comparing quotes

  • Can the work be phased to keep areas open?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Are they CHAS accredited or on Constructionline?
  • Whether primer will be used where the manufacturer specifies it
