Advice
Fire rated sealant in St Giles
We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. If you have joints picked up in a fire-stopping survey and gaps around pipes and cables through fire-resisting walls, we can help, whatever the surface.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in St Giles.
Big or small, you get the same one-year guarantee.

St Giles: your questions answered
Can you help a landlord with a rental near Tottenham Court Road station?

Is parking an issue for fire rated sealant in St Giles?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months.
Do you come to St Giles?
Yes. We work in St Giles and the rest of Greater London. For a quote, ring 0345 464 0079 or send us an email.
Can you work in occupied buildings?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. The order of work and access are planned with you.
How much does fire rated sealant cost in St Giles?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or send us an email and tell us what needs doing and where.
Can you tell me which gaps need fire stopping?
No, assessment isn’t 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.
Can you fill the gap behind a fire door frame?
Yes. The joint between frame and wall is sealed with a fire-rated sealant following the tested details. The door, its seals and closer are for a door specialist.
What affects the quote in St Giles
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether the work is at height
- Mould in or behind the old joints
- Which sealant suits the joint
- How many rooms, windows or areas are involved
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What to tell us for a quote
When you contact us, these details help:
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- Roughly how big the job is
- Any access issues, like height or stairs
If you’re in St Giles and need fire rated sealant, call 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you will get a clear quote before work begins.
Why deal with it now?
If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up gives you evidence that the item was dealt with. In a flat in St Giles, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Surface by surface
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail.
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the seal has something sound to bond to.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Report cracked or damaged seals as soon as you notice them
- Ask which product was used before you paint
- Plan fire stopping into any work that goes through walls or floors
- Include hidden areas like risers in routine checks
Do not add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

Fire rated sealant around St Giles
There are hotels and other places to stay in and around St Giles. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
Community buildings like Soho Baptist Chapel are part of the picture too: gaps around pipes and cables are worth checking after any building work there. If you look after a building such as St Josephs Catholic Primary School, service openings in fire-resisting walls need checking after any refurbishment.

Do you need fire rated sealant in St Giles?
Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
Common reasons people contact us include:
- Gaps filled with a product that is not fire-rated
- Gaps left after a refit or conversion
- Gaps where walls meet ceilings or slabs
- Door frames with gaps between frame and wall
Rented homes near Tottenham Court Road station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
