About our fire stopping in Mill Street
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. Reproducing the tested arrangement on site is the part we take care of. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and pipe penetrations, and what we’re called in for most is openings left by services added after handover and fire seals cut back for extra cables and never reinstated. For commercial sealant work in Mill Street, you deal with one contact from quote to sign-off, whether it’s one building or several.
Rural conversions around Mill Street can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

On site: what to expect
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, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For work around Mill Street, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- 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.

Advice
Honest limits
Being straight saves everyone time. Fresh joints won’t solve:
- Deciding what a wall or floor needs, which belongs to the designer
- Large openings beyond what any sealant detail covers
- Construction that lacks the fire resistance the seal relies on

Fire stopping around Mill Street: points for this area
Mill Street is about 55 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal. Fire stopping of openings and penetrations in England falls under Approved Document B. 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. Either way, we install the specified product to its tested detail.
Hotels like Stoke by Nayland Hotel, 1.3 miles to the west of Mill Street, are refurbished in phases, and each phase can open up compartment walls. Halls and meeting rooms at places like Church of St Mary sometimes gain new services, and any compartment wall crossed needs the specified seal. In a school such as Stoke-by-Nayland Church of England Primary School, fire-rated sealant goes in around service penetrations where it is specified.

Why deal with it now?
An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. Converted and older buildings near places like Mill Street tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Pricing service penetrations depends on how many there are, their condition and the access. Ask us for a fixed quote.

Common questions from Mill Street clients
Can you take on a job at a hospital such as Severalls Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What happens to BS 476 references for fire stopping in Mill 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.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Is your workmanship covered by a guarantee?
Yes. Workmanship is guaranteed for 12 months on every job.
Can staff carry on working while you are here?
Yes, with some planning. Tell us your site hours and access windows and we will plan around them.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Is Mill Street in your area?
Yes. We cover Mill Street, and you can phone 01277 525 020 or email a schedule or drawings to get started.
Surface by surface
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do and we’ll tell you what the detail says instead.
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening, with backing added if the detail requires it.
Looking after the joints
Regular inspection catches problems early. In particular:
- Check risers and ceiling voids after each round of works
- Agree the fire-stopping specification before services go in
- Put resealing into every M&E and fit-out package
- Have penetrations checked while they can still be seen
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job.
