How we handle fire stopping in Thorley Street
A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. Most enquiries involve penetration schedules that need working through and unsealed joints where partitions meet the slab, on linear gaps at wall heads, pipe penetrations and cable penetrations. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Thorley Street is the same: the right product in a properly prepared joint.
A job near Thorley Street is typically planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Questions about Thorley Street
Is Thorley Street too small for you to travel to?
No. Places such as Thorley Street are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you work on fire-rated sealing in hotels in Thorley Street?
Yes. We install fire-rated and intumescent sealant where it is specified. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
Is colour matching possible?
That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Is the work guaranteed?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
What sets the cost
What shapes the price:
- Whether old sealant has to be cut out first
- How accessible the joints are
- Induction, permit and paperwork requirements
- Phasing around occupants
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Before you send an enquiry
A good diagnosis starts with the right details. Tell us:
- How the joints are reached, and at what height
- Drawings or a marked-up plan, if available
- Any dates the work must fit around
- What the building is and how it’s used
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Issuing fire ratings or certificates for seals
- Fire risk assessments, a job for a competent assessor
- Walls or floors that aren’t fire-resisting to begin with
If you are not sure, just ring 01277 525 020 or email us and we’ll give you a straight answer before you book.
Where we work in Thorley Street

Fire-rated sealing for Thorley Street buildings
A 2-mile radius around Thorley Street takes in a number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
Older community buildings such as St. Swithin's Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Buildings near Thorley Street get the fire-rated product that’s specified, installed to its tested detail.

What the job involves on each surface
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we’ll say if that applies.
Site staff or a sealant specialist?
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.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
