Fire stopping for Tolworth sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Diagnose, treat, sign off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. In Tolworth, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Getting the site ready
- Send any specification or drawings in advance
- Tell staff and tenants when we will be in
- For older buildings, check the asbestos register before work

Fire stopping in Tolworth
Facilities managers in Tolworth often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it. With no specification in place, the first step sits with your designer or fire engineer, not with us. We work on joints between fire-resisting walls and floors, linear gaps at wall heads and pipe penetrations, and what we’re called in for most is seals that don’t match their tested detail and expanding foam used as fire stopping. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Tolworth, preparation and product choice get the time they need.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you will hear it from us.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Don’t let anyone top up a fire seal with the wrong product
- Ask which product is in place before decorating
- Arrange inspection before areas are covered up
- Record which product was used where
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.
Quoting for work in Tolworth
Before we quote, we look at:
- How much existing material needs removing
- The size and state of each joint
- Working within restricted access windows
- How accessible the joints are
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Before you send an enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Access details, including height
- Rough lengths or quantities, or drawings if you have them
- A wide shot and a close-up of the area
- Any specification or named product
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Common questions from Tolworth clients
Will you take on work at estates like Fairfield Trade Park, close to Tolworth?
Yes. Estates, retail parks and business parks around Tolworth, Fairfield Trade Park among them, are all within reach. To start, just give us a call on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Will you work in a care home in Tolworth without moving residents out?
Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we will work to them.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.
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.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Do you have third-party installer accreditation for fire stopping?
No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t, so it’s worth checking what your contract says. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
Why deal with it now?
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. In Tolworth, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Walls or floors that aren’t fire-resisting to begin with
- Openings that need collars, wraps, batts or boards rather than sealant
- Deciding what a wall or floor needs, which belongs to the designer
If you’re not sure, just ring 01277 525 020 or email us and we’ll give you a straight answer before you book.
Surfaces we seal
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Cable penetrations

Fire stopping around Tolworth: what changes locally
Tolworth has several hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product. Fire stopping of openings and penetrations in England falls under 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. We install whatever has been specified, to the product’s tested detail.
Hospital estates such as Tolworth Hospital, 0.5 miles south-west of Tolworth, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. For a site team at a college like Hillcroft College, 1 mile to the north-west of Tolworth, fire-rated sealing is best scheduled after the summer works. For a unit at a site such as Fairfield Trade Park, which lies north of Tolworth, new power or data runs between office and warehouse can breach a compartment wall.
