Fire stopping in Childs Hill
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. Most enquiries involve damaged fire seals in risers and voids and head-of-wall gaps with no fire seal, across cable penetrations, service gaps in risers and joints between fire-resisting walls and floors. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Childs Hill it comes down to the same thing: the right product in a properly prepared joint.
In a London area such as Childs Hill, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or email us and we will arrange a return visit.

Site staff or a sealant specialist?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Leave it or put it right?
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is typically a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Getting scaffold, permits or access booked in Childs Hill takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

From enquiry to sign-off
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking anything from one day to a planned run of visits, depending on the number of seals and the access. In Childs Hill, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Let us know about inductions and permits
- Point out parking and an unloading spot
- Share your working hours and any access restrictions

Advice
FAQs: Childs Hill
Does your area include sites such as Brent Cross Shopping Park, near Childs Hill?
Yes. Our area takes in Childs Hill and its surroundings, with estates and business parks such as Brent Cross Shopping Park included. Photos and a short description are enough for a first look.
Do you seal service penetrations in hotels around Childs Hill?
Yes, to the specification and the product’s tested detail. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Is colour matching possible?
It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Do you cover Childs Hill?
Yes. We take on work across Childs Hill.
Fire-rated sealing for Childs Hill buildings
A 2-mile radius around Childs Hill takes in a good number of hotels. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product. Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules.
Tenant changes at centres like O2 Centre (1.2 miles south-east of Childs Hill) often mean new services through walls between units. Wherever services are added at a hospital such as Royal Free Hospital, 1.5 miles to the south-east of Childs Hill, the compartment line has to be made good with the specified product.
Childs Hill is about 1 mile north-west of West Hampstead, in Greater London.

What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Issuing fire ratings or certificates for seals
- Walls or floors that aren’t fire-resisting to begin with
- Fire risk assessments, a job for a competent assessor
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.
What we seal
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Linear gaps at wall heads
- Cable penetrations
For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Childs Hill can sit alongside others in a wider programme across Greater London.
Common problems we fix in Childs Hill
Damage plays a part too. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe.
If one of these sounds familiar, it’s time for a closer look:
- Fire-stopping items raised at inspection or handover
- Openings found when ceilings come down for a refit
- Builders’ foam or ordinary silicone in compartment walls
- Damaged fire seals in risers and voids
Campus buildings at universities such as Middlesex University, 3 miles to the north-west of Childs Hill, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.
