Fire stopping near Seven Dials
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Different surfaces, different methods
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do.
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance along with any permits your site needs.
How we handle fire stopping in Seven Dials
On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, phone 01277 525 020 or send details through our quote form with the schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. We work on pipe penetrations, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and the failures we’re asked to look at most are expanding foam used as fire stopping and old intumescent sealant that has split away. Facilities teams, main contractors and managing agents in Seven Dials tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What we are called out for in Seven Dials
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.
What tends to prompt an enquiry:
- Open linear gaps along the top of fire-resisting walls
- Openings left by services added after handover
- Openings found when ceilings come down for a refit
- Builders’ foam or ordinary silicone in compartment walls
Colleges such as Scott's College, under half a mile north-west of Seven Dials, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
Questions to ask before you book
- How they’ll work around occupants
- What site paperwork they can supply
- Their public liability cover
- What the guarantee covers, and for how long
From enquiry to sign-off
Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Getting the site ready
- Explain the parking and delivery arrangements
- Tell us your opening times and when work is allowed
- Tell staff and tenants when we’ll be in

Compartment walls and floors in Seven Dials
There are a good number of hotels within about 2 miles of Seven Dials. 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. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. We install whatever has been specified, to the product’s tested detail.

At a university such as University of Notre Dame, which lies south of Seven Dials, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Aftercare for building managers
A few simple habits keep the new joints working:
- Record which product was used where
- Brief every trade that openings they make must be sealed
- Foam or ordinary sealant is never a fire-seal repair
- Ask which product is in place before decorating
Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.

Common questions from Seven Dials clients
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Can work at a site such as University of Notre Dame fit around teaching?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you hold third-party fire-stopping installer certification?
No. We are not members of a third-party fire-stopping installer scheme. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. Where a client or main contractor requires a scheme member, we will say so straight away rather than waste your time.
How many days will you need on site?
It depends on the scope, but the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we will give you a timescale with the quote.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Do you work in Seven Dials?
Yes. We cover Seven Dials, and the simplest way to start is to give us a call on 01277 525 020 or email a schedule or drawings.
How do we ask for 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 photographs and a postcode.
Work for main contractors and building owners
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
