Fire stopping in Hillingdon, done properly
On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, call the office on 01277 525 020 or send photos by email with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. If you have fire stopping installed outside its tested range and openings left by services added after handover, we can put it right, whatever the surface. A single leaking joint is often how a building in Hillingdon first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. Our part is installing the specified fire-rated sealant; tell us what records you need and we will confirm with the quote.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Look above ceilings when tiles are lifted for other jobs
- Brief every trade that openings they make must be sealed
- Settle who seals which penetrations at the start of a project
- Keep general-purpose fillers away from compartment walls
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Fire doors, dampers or other fire safety equipment
- Walls or floors that aren’t fire-resisting to begin with
- Approving the work on behalf of building control
Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly.
Surfaces we seal
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Service gaps in risers
- Cable penetrations
- Pipe penetrations
Fire stopping around Hillingdon: how the place shapes the job
A 2-mile radius around Hillingdon takes in a number of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail.
For a hospital such as Hillingdon Hospital, which lies south-west of Hillingdon, penetration sealing is typically phased ward by ward, with infection-control rules agreed first. Campus buildings at universities such as Brunel University of London, 1.1 miles to the west of Hillingdon, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. For a site team at a college like Uxbridge College (1.3 miles north-west of Hillingdon), fire-rated sealing is best scheduled after the summer works.
Hillingdon is about 2 miles north-west of Hayes, in Greater London. Any commercial site in Hillingdon is covered. Hillingdon is one of 764 places we cover in Greater London. There’s a separate page for London, roughly 15 miles from Hillingdon.
Commercial sites across UB10, UB8, UB9 and HA4 are covered for service penetrations. For a building on The Larches, Brampton Road and Clifton Gardens or nearby, we can quote for service penetrations. You’ll find Hillingdon on or near the B465 and B467, so getting applicators and materials to site is simple. We also cover Uxbridge (1 mile west), Ickenham (1 mile north), Cowley (2 miles south-west), Yiewsley (2 miles south-west) and Hayes (2 miles south-east) for service penetrations. Further afield, our area takes in London (15 miles east), City of Westminster (13 miles east), Marylebone (13 miles east), Kensington (11 miles east), St Pancras (14 miles east) and Hampstead (12 miles east).
Near you in Hillingdon
We work on buildings around Highfield Primary School, Norman Leddy Memorial Gardens and Oak Wood School and the streets around them. For rail, the closest station is West Drayton station, roughly 2.2 miles south-west of the centre. Nearby you’ll also find Hillingdon Museum and Archives Services (1.4 miles north-west) and Hillingdon Hospital (1 mile south-west). For a walk, there’s Northala Fields and Gutteridge Wood and Meadows.
Leave it or put it right?
Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Common questions from Hillingdon clients
What does the BS 476 change mean for fire-rated sealant in Hillingdon?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Share the building’s contractor rules and we will work to them.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
What do you charge?
There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Commercial clients in Hillingdon
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.
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 Hillingdon can sit alongside others in a wider programme.
How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking anything from one day to a planned run of visits, depending on the number of seals and the access. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Preparing the site
- Tell staff and tenants when we’ll be in
- Share your working hours and any access restrictions
- Send any specification or drawings in advance
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Different surfaces, different methods
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any outside it are raised with you.
