About our fire stopping in Irons Bottom
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls. We close the openings listed on your schedule, using the specified sealant and detail. We work on cable penetrations, small duct penetrations where the tested detail allows and pipe penetrations, and the usual reasons a site gets in touch are service penetrations left open after M&E works and head-of-wall gaps with no fire seal. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Irons Bottom is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
A job near Irons Bottom is typically planned around one visit, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Our workmanship is guaranteed for 12 months, in Irons Bottom as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Cost factors for service penetrations
Each job is priced on its own details. The main factors are:
- Travel to remote or island sites
- Working within restricted access windows
- Removal of failed or old sealant
- Quantities, in metres or numbers
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- The site address and postcode
- Specification clauses that apply
- Whether the building will be occupied during the work
- When you need the work done
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
Fire-rated sealing for Irons Bottom buildings
Central London is about 21 miles from Irons Bottom. Office refits around the commuter belt bring new cabling through fire-resisting 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. Our part stays the same: the specified product, installed to its tested detail.
In a building such as Emmanuel Church, any service penetration through a fire-resisting wall should be sealed to the specified detail. Office fit-outs on sites such as Fontigarry Farm Business Park (to the south-east of Irons Bottom) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.
Irons Bottom is about 2 miles south of Reigate, in Surrey. Businesses, contractors and managing agents in Irons Bottom can call on us for service penetrations. Irons Bottom is one of 379 places in Surrey on our list for service penetrations. London is covered too, around 21 miles from Irons Bottom.

From enquiry to sign-off
Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you. For work around Irons Bottom, 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.
- First we go through the drawings, schedule or specification for the seals.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Move anything stored against the joints
- Arrange parking or a loading space
- Tell us what induction or permit system the site runs

Building owners, agents and FMs in Irons Bottom
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
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.
General trades versus a specialist
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Do you need fire stopping in Irons Bottom?
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position, so it has to come out.
Things that usually lead to an enquiry:
- Seals disturbed by maintenance and left open
- Fire-stopping items raised at inspection or handover
- Openings left by services added after handover
- Openings found when ceilings come down for a refit
In a school such as Burys Court School, fire-rated sealant goes in around service penetrations where it is specified.
Comparing quotes
- How the joint faces will be prepared and primed
- Proof of insurance
- How long is the guarantee, and what does it include?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Leave it or put it right?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. One visit to deal with every failing joint makes more sense than several trips to a place like Irons Bottom. Photos of every joint help us quote for the whole job.

FAQs: Irons Bottom
Is a hospital such as East Surrey Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What happens to BS 476 references for fire stopping in Irons Bottom?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
What do you charge?
Every job gets its own fixed quote. For yours, give us a call on 01277 525 020 or email the details over with a description of the work.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, let us know and we will send them with the quote.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Can you quote from photos?
It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
