Need fire stopping in Tower Hamlets?
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Looking after the joints
To get the most from the new sealant:
- Put resealing into every M&E and fit-out package
- Report damaged or disturbed seals as soon as they’re spotted
- Agree the fire-stopping specification before services go in
- Get seals inspected before ceilings and boxing close
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small.
About our fire stopping in Tower Hamlets
Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, and they are easy to forget. Those on your schedule are closed with the specified product. We work on service gaps in risers, pipe penetrations and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are fire stopping installed outside its tested range and old intumescent sealant that has split away. A specialist sealant contractor works differently from a general builder: in Tower Hamlets, that means joint design, primers and backing rod as standard.
Around smaller places like Tower Hamlets, many commercial buildings are conversions or extensions of older ones, so the wall or floor a service passes through isn’t always what the drawings assume. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Questions about Tower Hamlets
Is Tower Hamlets off your patch?
No. Places such as Tower Hamlets are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Can you work at a site such as White Cliffs Business Park, by Tower Hamlets?
Yes. Our area takes in Tower Hamlets and its surroundings, with estates and business parks such as White Cliffs Business Park included. Photos and a short description are enough for a first look.
How much does the work cost?
Each job is quoted on its own details. For yours, call the office on 01277 525 020 or email a schedule or drawings with a description of the work.
How long does a job like this take?
It depends on the scope, but the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Which standards are fire seals tested to?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested; installing to the detail is what carries that across to site.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Can you reseal penetrations after our M&E works?
Yes, provided a specification covers them. New services after M&E works often breach existing seals and we close them with the specified product.
Do you need fire stopping in Tower Hamlets?
Damage plays a part too. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe and the opening isn’t always resealed.
It’s worth sending us details if you spot any of the following:
- Seals disturbed by maintenance and left open
- Unsealed joints where partitions meet the slab
- Openings found when ceilings come down for a refit
- Fire-stopping items raised at inspection or handover
Colleges such as East Kent College, 0.5 miles to the east of Tower Hamlets, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

- Whether old or failed sealant will be cut out, not overlaid
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Plastic pipes whose detail calls for a collar or wrap
- Construction that lacks the fire resistance the seal relies on
- Signing off or certifying a building’s fire stopping
If in doubt, phone 01277 525 020 or email drawings and photos and we will say what we think before you book.

Quoting for work in Tower Hamlets
Each job is priced on its own details. The main factors are:
- Any access equipment needed
- Distance, for remote addresses
- How much existing material needs removing
- Site requirements such as inductions and permits
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
What to include in your enquiry
For an accurate fixed quote, we need to understand the site. Send us:
- The postcode of the building
- Asbestos survey details if the building is older
- Whether the building will be occupied during the work
- The product your specification calls for
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or email the details over.
When to bring in a specialist
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.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Service penetrations in Tower Hamlets buildings
Central London is about 65 miles from Tower Hamlets. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Fire stopping of openings and penetrations in England falls under Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
Older community buildings such as Church of St Peter and St Paul that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Large healthcare estates like Buckland Hospital, less than half a mile north-west of Tower Hamlets, change their services often, so penetration seals are worth checking after M&E work.
