Fire stopping near Spitalfields
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Aftercare for building managers
Problems stay small when the joints are checked regularly. In particular:
- Check risers and ceiling voids after each round of works
- 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
After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
Fire stopping in Spitalfields
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls. Those on your schedule are closed with the specified product. If you have fire sealant pulled out of the opening and unsealed openings around new pipes and cables, we can put it right. A specialist sealant contractor works differently from a general builder: on jobs in Spitalfields, preparation and product choice get the time they need.
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.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.
What sets the cost
Each job is priced on its own details. The things that drive the figure:
- How much there is to seal
- Distance, for remote addresses
- Joint width, depth and condition
- Phasing around occupants
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
Before you send an enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- The product your specification calls for
- Clear photos of the problem areas
- Any dates the work must fit around
- Approximate linear metres or a joint schedule
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or send photos by email.
Penetration seals near Spitalfields
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. A good number of hotels sit less than 2 miles from Spitalfields. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product.
Office fit-outs on sites such as Princes Court Business Centre, 0.9 miles south-east of Spitalfields, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Wherever services are added at a hospital such as Royal London Hospital, 0.7 miles to the east of Spitalfields, the compartment line has to be made good with the specified product. Workshops and IT rooms at colleges like London College of Marketing and Technology (less than half a mile south-east of Spitalfields) are re-serviced often, leaving penetrations to seal.
Spitalfields is about 1 mile north-east of London, in Greater London. Across the E1 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 764 places in Greater London, from busy centres to rural villages.

FAQs: Spitalfields
Could you schedule work at a campus like London Metroplitan University: Aldgate Campus for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Would you work within a site like Royal London Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
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.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Is fire stopping in Scotland covered by different guidance?
Scotland sets its own building regulations, with Technical Handbooks, and England uses Approved Document B. Wherever the site is, our work follows the specification and the tested detail.
How long will the new sealant 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.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Why it’s worth doing now in Spitalfields
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

When to bring in a specialist
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Most London premises stay occupied while we’re 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.
- 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.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Preparing the site
- Share the asbestos register for older buildings
- Confirm the product named in the specification
- Share your working hours and any access restrictions
