How we handle fire rated sealant in Colliers Wood
We do not assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on linear gaps, plasterboard & masonry and door frames, and common reasons people get in touch are damaged fire sealant left by other trades and joints picked up in a fire-stopping survey.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in Colliers Wood needs to stay open, work can be planned outside normal hours.
There’s a 12-month guarantee on every job, large or small.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

When to call us in Colliers Wood
Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
Common reasons people contact us are:
- Standard silicone or caulk in a fire-stopping gap
- Gaps flagged on a fire risk assessment
- Cracked or shrunken fire-rated sealant
- Gaps left after a refit or conversion
For landlords with property near Tooting station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Colliers Wood questions
Is parking an issue for fire rated sealant in Colliers Wood?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Can you help a landlord with a rental near Tooting station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do you carry out fire risk assessments?
No, assessment is not something we do. Once you have a specification or action list from your assessor or designer, we’ll quote for the sealant work on it.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. In Colliers Wood, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your records.
How to prepare
- Clear items away from the joints we are working on
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks

Commercial buildings in Colliers Wood
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
Managing a site like Sellincourt Primary School? Then fire-stopping around service openings should be restored whenever new services go in. As a London address, Colliers Wood can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

How to look after the new joints
After the cure time, these simple habits help:
- Allow for resealing whenever new services are run
- Ask every contractor to reseal any fire stopping they disturb
- Do not paint over fire sealant until it has cured
- Check risers, ceiling voids and cupboards during building checks
Don’t add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Issuing a fire rating or certificate for a building
- Fire doors that need new seals, closers or hardware
- Openings too large for sealant, which need batts, boards or another system

How the job changes by surface
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We work through the gaps on your assessment, flat by flat if needed.
