Fire stopping in Gordon Hill
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. The enquiries we see most involve seals disturbed by maintenance and left open and improvised or mixed-product fire seals, across service gaps in risers, cable penetrations and joints between fire-resisting walls and floors. One point of contact handles commercial sealant work in Gordon Hill from the first photographs to the final walk-round, for single jobs and planned programmes alike.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Whether the work must be split into stages
- Quantities, in metres or numbers
- The site’s rules and procedures
- Which sealant the job calls for
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
What we need to price the job
To price the job accurately, we need to understand the site. Useful things to include:
- Specification clauses that apply
- Approximate linear metres or a joint schedule
- The asbestos register, for older buildings
- Any dates the work must fit around
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Signs you need fire stopping in Gordon Hill
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.
Clients normally get in touch after noticing one or more of the following:
- Fire sealant pulled out of the opening
- Service penetrations left open after M&E works
- Hidden openings found during inspections
- Open linear gaps along the top of fire-resisting walls
For a hospital such as St Michael's Community Hospital (less than half a mile south-east of Gordon Hill), penetration sealing is usually phased ward by ward, with infection-control rules agreed first.

Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Settle who seals which penetrations at the start of a project
- Check risers and ceiling voids after each round of works
- Get seals inspected before ceilings and boxing close
- Leave fire sealant to cure fully before covering it
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way, or a new specification from the designer.
Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, and it helps at inspections.

Questions about Gordon Hill
Do you work on fire-rated sealing in hotels in Gordon Hill?
Yes, where the specification calls for fire-rated sealant. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
Can you take on a job at a hospital such as St Michael's Community Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Is colour matching possible?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Work for main contractors and building owners
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Gordon Hill can form part of a wider programme.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
How a job runs
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- 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.
Before we start on site
- Arrange parking or a loading space
- Move anything stored against the joints
- Send asbestos survey details if the building is pre-2000

What happens if it’s left?
A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Compartment walls and floors in Gordon Hill
Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements. The area within 2 miles of Gordon Hill holds several hotels. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product.
At a retail site such as Enfield Retail Park, 1.5 miles to the south-east of Gordon Hill, walls between units may be fire-resisting, so services added in a refit need the specified seal. For a site team at a college like Capel Manor College, 1.7 miles to the north-east of Gordon Hill, fire-rated sealing is best scheduled after the summer works.
