Fire-rated sealant in Waterloo, Greater London
Intumescent and fire-rated sealant around gaps, frames and service penetrations for Waterloo, backed by a one-year guarantee. Call for a quick quote.
- Seals cut through by electricians, plumbers or data installers
- Standard silicone or caulk in a fire-stopping gap
- Gaps left after a refit or conversion
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Fire rated sealant for homes and businesses in Waterloo
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. We work on pipe & cable gaps, service penetrations and door frames, and people most often call us about standard silicone or caulk in a fire-stopping gap and unsealed gaps around fire door frames.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Waterloo, and room-by-room programmes can be planned where needed.
Your job is guaranteed for a year, as with all our work.

What happens on the day
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a handful of gaps, and longer for a whole building. In Waterloo, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any tricky access
- Move anything stored near the joints

Advice
When to call us in Waterloo
Much fire stopping is hidden: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
The most common problems we see are:
- Fire stopping disturbed by later work
- Open gaps behind door architraves
- Gaps where walls meet ceilings or slabs
- Joints picked up in a fire-stopping survey
As a London address, Waterloo can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
What your quote should include
- Whether they seal over old material or remove it
- What happens if the job turns out different
- Which colour the sealant will be
- How much experience the applicator has
Waterloo questions
Do you work for landlords with property near London Waterloo station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Do you work in hotels near Waterloo?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Where do you work from?
We work from Crawley. We cover Waterloo and the rest of Greater London, along with the rest of our area.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can I add another job to the visit?
Yes. Just list everything you need and you will get one quote.
What does intumescent mean?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Ask which product was used before you paint
- Look in service cupboards and ceiling voids from time to time
- Tell trades working in the building that fire seals must be put back
- Report cracked or damaged seals as soon as you notice them
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint, so ask us which we used.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the list grows.
What fire rated sealant looks like in Waterloo
Waterloo has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
Schools such as Oasis Academy Johanna are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. For buildings such as Christ Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Why it’s worth doing now in Waterloo
An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the work involved is often modest. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Waterloo, the repair is bigger than the sealant job would have been.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
