What we are called out for in Orpington
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls.
Any of the following is a good reason to get the joints checked over:
- Fire seals cut back for extra cables and never reinstated
- Non-fire-rated filler around services
- Unsealed joints where partitions meet the slab
- Snag lists that include open service penetrations
At a university such as University of Greenwich Avery Hill Campus, 4.4 miles north of Orpington, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

- Their public liability cover
- Their plan for phasing and protecting the area
- Whether old or failed sealant will be cut out, not overlaid
Fire stopping in Orpington
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to 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. The enquiries we see most involve damaged fire seals in risers and voids and snag lists that include open service penetrations, across joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and linear gaps at wall heads. Whoever orders the work in Orpington, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we’ll confirm with the quote.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

We check first that sealant really is the fix. It isn’t the answer for:
- Issuing fire ratings or certificates for seals
- Walls or floors that aren’t fire-resisting to begin with
- Large openings beyond what any sealant detail covers
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

What else we do in Orpington
Looking after the joints
To get the most from the new sealant:
- Record which product was used where
- Foam or ordinary sealant is never a fire-seal repair
- Arrange inspection before areas are covered up
- Flag new cables with no seal around them
Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original.
Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, and it helps at inspections.
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Redoing a failed joint usually 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.
Diagnose, treat, sign off
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a job in Orpington, access comes first. Send the building rules and access times with your enquiry.
- 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.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Getting the site ready
- Move anything stored against the joints
- Agree which areas must stay open
- Let building users know which areas are affected

Why it’s worth doing now in Orpington
Open penetrations multiply: each new service adds to the list. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Fire stopping in Orpington: the local picture
Several hotels sit less than 2 miles from Orpington. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. With tenants changing and fit-outs following, London buildings see service routes altered again and again. We install fire-rated sealant where it is specified and work within the building manager’s permit system.
In a hotel such as TLK Apartments & Hotel, 0.8 miles to the north-east of Orpington, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. Colleges such as Bromley College (to the west of Orpington) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Questions we’re asked in Orpington

Is fire stopping in Scotland covered by different guidance?
Scotland sets its own building regulations, with Technical Handbooks, while England relies on Approved Document B. Either way, we install the specified sealant to its tested detail.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Who decides which product is used?
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.
