Fire stopping for commercial buildings in Puddle Dock
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. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. If you have seals that don’t match their tested detail and non-fire-rated filler around services, we can put it right, whatever the surface. Searching for sealant specialists in Puddle Dock? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
In a London area such as Puddle Dock, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Fire-rated sealing for Puddle Dock buildings
London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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.
On estates like Childerditch Industrial Park (1.8 miles north-east of Puddle Dock), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. Workshops and IT rooms at colleges like New City College (to the west of Puddle Dock) are re-serviced often, leaving penetrations to seal. Theatres, wards and plant rooms at sites like Hartswood Hospital (2.8 miles north of Puddle Dock) all have compartment walls crossed by services.

Common questions from Puddle Dock clients
Is a hospital such as Hartswood Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you take on jobs in Puddle Dock where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
Do you design or specify fire stopping?
No. The specification comes from your designer, fire engineer or building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Can you reseal penetrations after our M&E works?
Yes. Share the penetration schedule and product details. We can follow the services contractor floor by floor.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
When to bring in a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Diagnose, treat, sign off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. In Puddle Dock, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Arrange parking or a loading space
- Share your working hours and any access restrictions

Advice
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Gaps in walls that were never built as compartment walls
- Approving the work on behalf of building control
- Deciding what a wall or floor needs, which belongs to the designer
If in doubt, call 01277 525 020 or use the quote form and we’ll say what we think.
Surfaces we seal
- Service gaps in risers
- Linear gaps at wall heads
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Cable penetrations
Leave it or put it right?
Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
