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 Bakers Arms
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you have open linear gaps along the top of fire-resisting walls and seals that don’t match their tested detail, we can help. Whoever orders the work in Bakers Arms, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
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.
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’re upfront about that.

Building owners, agents and FMs in Bakers Arms
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Looking after the joints
For the best life from the joints:
- Brief every trade that openings they make must be sealed
- Ask which product is in place before decorating
- Get seals inspected before ceilings and boxing close
- File the specified details where the next contractor can find them
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open, not months later.
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 other benefits follow. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
A quote for service penetrations depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

Our process
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Planning a London job such as one in Bakers Arms starts with access. Send the building rules and access times with your enquiry.
- 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.
- Where the detail needs backing, it goes in at the stated depth.
- 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.
What we need from you
- Send any specification or drawings in advance
- Share your working hours and any access restrictions
- Share the asbestos register for older buildings

Doing it in-house
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.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Where services cross fire walls in Bakers Arms
The 2 miles around Bakers Arms include 41 care or nursing homes. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules.
Colleges such as Leyton Sixth Form College (0.5 miles east of Bakers Arms) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Hospital estates such as Whipps Cross University Hospital (to the east of Bakers Arms) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

What we’re called out for in Bakers Arms
Some service penetrations were never sealed at all. Inspections, refurbishments and ceiling access typically bring them to light.
These are often picked up first by site or facilities staff:
- Openings found when ceilings come down for a refit
- Damaged fire seals in risers and voids
- Snag lists that include open service penetrations
- Expanding foam used as fire stopping
For a unit at a site such as Lennox Trading Estate, 0.5 miles west of Bakers Arms, new power or data runs between office and warehouse can breach a compartment wall.
Questions to ask before you book
- Will failed sealant be removed rather than covered?
- Is the sealant right for the movement and the substrate?
- Do they follow the manufacturer’s priming guidance?
- The terms of the workmanship guarantee
Common questions from Bakers Arms clients
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Bakers Arms?
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.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited and a Constructionline member.
