FAQs: Twickenham
Can you seal penetrations in a hotel in Twickenham after a refit?
Yes, where fire-rated sealant is the specified product. Each seal follows the tested detail, and rooms are done in turn.
What happens to BS 476 references for fire stopping in Twickenham?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
What do you charge?
Each job is quoted on its own details. For yours, call 01277 525 020 or email drawings and photos with a description of the work.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
How long do sealant joints 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.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
About our fire stopping in Twickenham
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, often unnoticed. Those on your schedule are closed with the specified product. We work on joints between fire-resisting walls and floors, pipe penetrations and service gaps in risers, and what we’re called in for most is fire seals cut back for extra cables and never reinstated and head-of-wall gaps with no fire seal. Searching for sealant specialists in Twickenham? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
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 will confirm with the quote.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

From enquiry to sign-off
Tell us your site hours and access windows and we’ll 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. All of Greater London is in the ULEZ, and kerbside space in Twickenham can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We start with your penetration schedule, drawings or specification.
- 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.
- Foam, ordinary sealant and debris come out.
- 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
- Send your site hours and access windows
- For older buildings, check the asbestos register before work
- Flag any permit to work we will need

Related advice
Different surfaces, different methods
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point against the detail’s limits, and any that don’t are flagged.
Do you need fire stopping in Twickenham?
Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.
Look out for the following:
- Penetration schedules that need working through
- Fire-rated sealant that has cracked or shrunk back
- Seals that don’t match their tested detail
- Open linear gaps along the top of fire-resisting walls
Wherever services are added at a hospital such as Teddington Memorial Hospital (to the south of Twickenham) the compartment line has to be made good with the specified product.
Before you book anyone
- How they’ll work around occupants
- Are they CHAS accredited or on Constructionline?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- The terms of the workmanship guarantee
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Keep general-purpose fillers away from compartment walls
- Keep product data and details in the fire safety file
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Settle who seals which penetrations at the start of a project
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t.
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.
When to bring in a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
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.
Compartment walls and floors in Twickenham
Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. We seal to the specification and the product’s tested detail, working within the building’s permits. For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
Workshops and IT rooms at colleges like Richmond-upon-Thames College, under half a mile north-west of Twickenham, are re-serviced often, leaving penetrations to seal. Industrial units on estates such as Heathlands Industrial Estate, less than half a mile south of Twickenham, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.
