How we handle fire stopping in Roxeth
Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it. Where there isn’t one, the designer or fire engineer needs to set one first. Most enquiries involve old intumescent sealant that has split away and unsealed penetrations discovered above suspended ceilings, on cable penetrations, pipe penetrations and linear gaps at wall heads. Looking for mastic applicators who cover Roxeth? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
In a London area such as Roxeth, 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.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Have penetrations checked while they can still be seen
- Report damaged or disturbed seals as soon as they’re spotted
- Check with the data sheet before painting over fire sealant
- Agree the fire-stopping specification before services go in
Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.
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, which saves guesswork.
Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. For a job in Roxeth, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Let us know about inductions and permits
- Point out any areas we must not close

What else we do in Roxeth
Signs you need fire stopping in Roxeth
Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.
Things that usually lead to an enquiry:
- Penetration schedules that need working through
- Head-of-wall gaps with no fire seal
- Improvised or mixed-product fire seals
- Old intumescent sealant that has split away
For a site team at a college like St Dominic's Sixth Form College, less than half a mile to the south-east of Roxeth, fire-rated sealing is best scheduled after the summer works.
What your quote should include
- How they’ll work around occupants
- Do they follow the manufacturer’s priming guidance?
- What site paperwork they can supply
- Their pre-qualification and accreditations
When something else is needed
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Fire doors, dampers or other fire safety equipment
- Approving the work on behalf of building control
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If you are not sure, just ring 01277 525 020 or send photos by email and we will give you a straight answer before you book.
Joints and surfaces we work on
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Pipe penetrations
- Cable penetrations
- Service gaps in risers
- Small duct penetrations where the tested detail allows
Where services cross fire walls in Roxeth
Roxeth has two care or nursing homes no more than 2 miles away. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. Roxeth has a good number of hotels close by, all within 2 miles. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
In a retail centre such as St. George's Shopping Centre (1 mile north-east of Roxeth), any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. Office fit-outs on sites such as Harrovian Business Village (to the north of Roxeth) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Roxeth: questions and answers
Will you plan work around the academic year at somewhere like Westminster University?
Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you take on work at healthcare sites like Cygnet Hospital?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Can you quote from photos?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.
Do you work in Roxeth?
Yes. Roxeth is in our area and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. For a quote, give us a call on 01277 525 020 or email us.
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.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
