Fire stopping for Hassell Street sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Quoting for work in Hassell Street
Before we quote, we look at:
- Joint width, depth and condition
- Phasing around occupants
- Induction, permit and paperwork requirements
- Whether old sealant has to be cut out first
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What to include in your enquiry
We can often quote from photographs and a few details. It helps to include:
- Where the site is, with the postcode
- When you need the work done
- Specification clauses that apply
- Access details, including height
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
Fire stopping in Hassell Street, done properly
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, 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. We work on service gaps in risers, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are fire sealant pulled out of the opening and non-fire-rated filler around services. One point of contact handles commercial sealant work in Hassell Street from the first photographs to the final walk-round, for single jobs and planned programmes alike.
For a smaller site near Hassell Street, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Leave it or put it right?
An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first. One visit to deal with every failing joint makes more sense than several trips to a place like Hassell Street. Send photographs of each area and we’ll quote for the lot.
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote when you’re ready.
Why us?
- CHAS accredited
- Constructionline member for supplier checks
- Public liability insurance in place
- Products installed to the manufacturer’s instructions

When to call us in Hassell Street
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.
Things that normally lead to an enquiry:
- Expanding foam used as fire stopping
- Head-of-wall gaps with no fire seal
- Improvised or mixed-product fire seals
- Unsealed penetrations discovered above suspended ceilings
For a hospital such as William Harvey Hospital, which lies south-west of Hassell Street, penetration sealing is usually phased ward by ward, with infection-control rules agreed first.
Questions to ask before you book
- How the existing material will be dealt with
- Their public liability cover
- What site paperwork they can supply
- Whether primer will be used where the manufacturer specifies it
Questions we’re asked in Hassell Street
Can you work on a hospital site such as William Harvey Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What does the BS 476 change mean for fire-rated sealant in Hassell Street?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.
How do I request a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit normally takes anything from one day to a planned run of visits, depending on the number of seals and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
How the job changes by surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits.
Plastic pipes
Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail.
Fire stopping around Hassell Street: what changes locally
Hassell Street lies roughly 52 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal. Fire stopping of openings and penetrations in England falls under Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
For a school such as Wye School, penetration sealing fits best at the end of the summer works.
Hassell Street is about 6 miles north-east of Ashford, in Kent. Across the TN25 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Kent coverage takes in 931 places. London is covered too, around 52 miles from Hassell Street.

What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Gaps in walls that were never built as compartment walls
- Fire doors, dampers or other fire safety equipment
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If you are not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Cable penetrations
- Pipe penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
From enquiry to 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.

- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
