Fire Stopping in Baker Street
Commercial sealant work in Baker Street for contractors, FMs and building owners: fire-rated and intumescent sealing of service penetrations and linear gaps, with a fixed quote first.
- Head-of-wall gaps with no fire seal
- Hidden openings found during inspections
- Seals disturbed by maintenance and left open
Fire stopping for Baker Street sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
How we handle fire stopping in Baker Street
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. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. We work on linear gaps at wall heads, pipe penetrations and joints between fire-resisting walls and floors, and what we are called in for most is unsealed joints where partitions meet the slab and openings left by services added after handover. A specialist sealant contractor works differently from a general builder: in Baker Street, that means joint design, primers and backing rod as standard.
For a smaller site near Baker Street, we plan to do all the penetrations in one go, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

When to call us in Baker Street
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in, which then have to be put right.
These are often picked up first by site or facilities staff:
- Openings left by services added after handover
- Fire-stopping items raised at inspection or handover
- Openings found when ceilings come down for a refit
- Head-of-wall gaps with no fire seal
On estates like Coward Trading Estate (2.2 miles south of Baker Street), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- Whether primer will be used where the manufacturer specifies it
- Are they CHAS accredited or on Constructionline?
- How joint depth will be controlled
Different surfaces, different methods
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers, and we work within it.
Small ducts
Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork normally needs a different solution set by the designer and we flag that rather than guess.
Baker Street: questions and answers
Can work at a site such as USP College fit around teaching?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
What happens to BS 476 references for fire stopping in Baker Street?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Maintenance after handover
Regular inspection catches problems early. Specifically:
- File the specified details where the next contractor can find them
- Get seals inspected before ceilings and boxing close
- Look above ceilings when tiles are lifted for other jobs
- Brief every trade that openings they make must be sealed
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Fire stopping around Baker Street: what changes locally
In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Baker Street has several hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product.
For a building such as St Giles & All Saints Church, new heating or data runs are the usual reason penetrations need sealing. On a hospital site such as Orsett Hospital (less than half a mile east of Baker Street), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Baker Street is about 2 miles north-east of Grays, in Thurrock. We cover Baker Street, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Thurrock coverage takes in 27 places. There’s a separate page for London, about 19 miles away.

If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think before you book.
What we seal

- Joints between fire-resisting walls and floors

- Service gaps in risers
- Pipe penetrations
Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For work around Baker Street, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Point out parking and an unloading spot
- Tell us your opening times and when work is allowed
- Have the specification and drawings to hand
