Fire rated sealant in Tokyngton
Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That is the part we focus on, gap by gap. Common call-outs are for door frames with gaps between frame and wall and fire stopping disturbed by later work, across service penetrations, flats & HMOs and door frames.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in Tokyngton can’t close.
Whatever the size of the job, it’s backed by our one-year guarantee.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Never patch a fire seal with standard sealant
- Make resealing part of every contractor’s brief
- Do not paint over fire sealant until it has cured
- Allow for resealing whenever new services are run
Do not drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
What affects the cost of fire rated sealant
The quote reflects the job in front of us. We look at:
- How easy the joints are to reach
- Any working-time requirements on site
- The number of rooms or windows
- The size of the job
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- A few pictures by email, if you can
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- The rough size of the job

Different surfaces, different methods
Flats and HMOs
Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and the locations noted.
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
FAQs for Tokyngton

When to call us in Tokyngton
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. Rushed fire stopping is common.
Common reasons people contact us include:
- Unsealed gaps around fire door frames
- Gaps around pipes and cables through fire-resisting walls
- Seals cut through by electricians, plumbers or data installers
- Holes left by a change of layout
Community buildings like St Michael the Archangel are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Commercial buildings in Tokyngton
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
Managing a site like Elsley Primary School? Then fire-stopping around service openings should be restored whenever new services go in. Tokyngton is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Why act early in Tokyngton
For some gaps, sealant isn’t the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we will tell you. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Tokyngton, the repair is bigger than a sealant job.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

- Domestic, commercial and hotel work
- Anti-fungal sanitary silicone in wet areas
