Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Check risers and ceiling voids after each round of works
- Brief every trade that openings they make must be sealed
- Record which product was used where
- Ask the designer to confirm details early on refits
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, so check the product data first.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small compared with dozens found at once.
About our fire stopping in South Wimbledon
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, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. We work on joints between fire-resisting walls and floors, service gaps in risers and linear gaps at wall heads, and the failures we are asked to look at most are seals disturbed by maintenance and left open and open linear gaps along the top of fire-resisting walls. Whether you call it commercial sealant work, mastic application or joint sealing, the work in South Wimbledon is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In a London area such as South Wimbledon, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Why act early in South Wimbledon
A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product. In South Wimbledon, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Fire stopping around South Wimbledon: points for this area
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. In England, Approved Document B covers fire stopping of openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail.
Hospital estates such as St George's Hospital, 1 mile north-east of South Wimbledon, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Workshops and IT rooms at colleges like Wimbledon College of Arts (to the south-west of South Wimbledon) are re-serviced often, leaving penetrations to seal. Where a unit on an estate such as Nelson Trading Estate, 0.5 miles south of South Wimbledon, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Most London premises stay occupied while we’re on site, 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.
- 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.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Have the specification and drawings to hand
- Share the asbestos register for older buildings
- Let building users know which areas are affected

Your questions answered
Could you schedule work at a campus like Kingston University Roehampton Vale Campus for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you take on jobs in South Wimbledon where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Do the same rules apply to fire stopping in Scotland?
Our work covers Greater London, the South East and every Scottish council area. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, with proprietary products tested for the end use.
Do you work in South Wimbledon?
Yes. We cover South Wimbledon, within our coverage of Greater London, South East England and Scotland. For a quote, call the office on 01277 525 020 or send details through our quote form.
Are you members of a third-party fire-stopping installer scheme?
No, and we’d rather be clear about that. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them. Where it isn’t required, we install the specified sealant to the maker’s details.
When something else is needed
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Walls or floors that aren’t fire-resisting to begin with
- Approving the work on behalf of building control
- Writing the fire-stopping specification
If in doubt, phone 01277 525 020 or use the quote form and we will say what we think.
Joints and surfaces we work on
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Linear gaps at wall heads
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Service gaps in risers
For managing agents and facilities managers
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
