Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How we handle fire stopping in Hainault
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance. Most enquiries involve head-of-wall gaps with no fire seal and damaged fire seals in risers and voids, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and cable penetrations. For commercial sealant work in Hainault, you deal with one contact from quote to sign-off, whether it’s one building or several.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you’ll hear it from us.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Your questions answered
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Hainault?
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.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you quote from photographs?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
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, so we’ll confirm the curing time on the day.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member.
When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Openings that need collars, wraps, batts or boards rather than sealant
- Signing off or certifying a building’s fire stopping
- Reviewing a building’s overall fire safety
If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
Joints and surfaces we work on

Service penetrations in Hainault buildings
Hainault has several hotels close by, all within 2 miles. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Three care or nursing homes sit less than 2 miles from Hainault. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. We install fire-rated sealant to the tested detail where it is specified.
Hotels like London Chigwell Prince Regent Hotel, 1.2 miles west of Hainault, are refurbished in phases, and each phase can open up compartment walls. For a hospital such as King George Hospital (1.9 miles south-east of Hainault), penetration sealing is normally phased ward by ward, with infection-control rules agreed first.
Hainault is about 2 miles east of Woodford, in Greater London. Businesses, contractors and managing agents in Hainault can call on us for service penetrations, as part of our coverage of Greater London. 764 places across Greater London fall within our area, including Hainault.

Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. All of Greater London is in the ULEZ, and kerbside space in Hainault can be scarce. 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.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- 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
- Flag any permit to work we will need
- Clear stock, furniture or equipment away from the joints
- Send your site hours and access windows

When to call us in Hainault
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
Clients typically get in touch after noticing one or more of the following:
- Fire sealant pulled out of the opening
- Unsealed joints where partitions meet the slab
- Hidden openings found during inspections
- Non-fire-rated filler around services
At a college such as New City College (1.8 miles south of Hainault), checking penetration seals after summer M&E works is good practice.
What your quote should include
- How they handle RAMS and site documents
- Can the work be phased to keep areas open?

- Do they follow the manufacturer’s priming guidance?

Different surfaces, different methods
Plastic pipes
Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail.
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.
