Fire stopping across Laleham
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
On site: what to expect
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. Work in places the size of Laleham is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Let us know about inductions and permits
- Move anything stored against the joints
- Share the asbestos register for older buildings

Fire stopping for commercial buildings in Laleham
A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in. We work on small duct penetrations where the tested detail allows, pipe penetrations and joints between fire-resisting walls and floors, and the failures we are asked to look at most are fire-rated sealant that has cracked or shrunk back and hidden openings found during inspections. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Laleham, that means joint design, primers and backing rod as standard.
Converted and extended buildings around places like Laleham can mix old and new construction, so it’s worth confirming the wall or floor type before choosing the seal. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Common questions from Laleham clients
Is Laleham off your patch?
No. Places such as Laleham are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Could you schedule work at a campus like Royal Holloway University for the vacation?
Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is the work guaranteed?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
What does an EI 60 rating mean?
BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Classification follows BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. The rating applies to the product as tested.
Is the BS 476 change in 2029 relevant to fire stopping?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, subject to transitional arrangements. In Scotland, the Technical Handbook sets its own guidance.
Can you fire stop behind the services contractors?
Yes. Share the penetration schedule and product details and a fixed quote follows. Work can run area by area behind the M&E trades so areas aren’t left open.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Issuing fire ratings or certificates for seals
- Deciding what a wall or floor needs, which belongs to the designer
- Reviewing a building’s overall fire safety
If in doubt, ring 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

How the quote is worked out
Quotes vary with the job. It mainly depends on:
- Location, for remote and island sites
- Any access equipment needed
- How much existing material needs removing
- Site requirements such as inductions and permits
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
Before you send an enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Clear photos of the problem areas
- How the joints are reached, and at what height
- When you need the work done
- Any specification or named product
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or use the quote form.
Aftercare for building managers
To get the most from the new sealant:
- File the specified details where the next contractor can find them
- Report damaged or disturbed seals as soon as they’re spotted
- Look above ceilings when tiles are lifted for other jobs
- Settle who seals which penetrations at the start of a project
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
Why deal with it now?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Compartment walls and floors in Laleham
There are a good number of hotels within about 2 miles of Laleham. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product. Laleham is about 18 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.
At a university such as Royal Holloway University, which lies west of Laleham, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. Office fit-outs on sites such as Pine Trees Business Park, 1.6 miles to the north-west of Laleham, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Hospital estates such as Ashford Hospital (to the north of Laleham) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
