Fire rated sealant for homes and businesses in Belgravia
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We work on door frames, flats & HMOs and plasterboard & masonry, and the jobs we see most are unsealed gaps where pipes and cables go through a wall and linear gaps at the head of walls.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Belgravia, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
All our work is covered by a one-year guarantee.

Quotes for fire rated sealant in Belgravia
Jobs vary more than people expect. The main factors:
- Any mould that needs treating
- Which sealant suits the joint
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
What we need to know
What to tell us when you ask for a quote:
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
- A few pictures by email, if you can
- Roughly how big the job is
Want a quote for fire rated sealant? Please call 0345 464 0079 or drop us an email with a few details. We will explain what we’d do and send you a clear quote before work begins.
How to look after the new joints
Looking after new joints is easy:
- Tell trades working in the building that fire seals must be put back
- Include hidden areas like risers in routine checks
- Check whether a sealant can be painted before decorating over it
- Report cracked or damaged seals as soon as you notice them
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint, so ask us which 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
We’d rather tell you now than do work that will not last, so these are the limits:
- Large holes that need a different fire-stopping system
- Fire doors that need new seals, closers or hardware
- Walls or floors that weren’t built to resist fire
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before you book.

Questions from Belgravia
Do you work for landlords with property near London Victoria station?
Yes. We work for landlords and letting agents as well as householders. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Can parking be tricky for a visit in Belgravia?
Parking in Belgravia, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
What does fire rated sealant cost?
Every job is different, so each one gets its own quote. To get one, ring 0345 464 0079 or drop us an email with a short description of the job.
Do you offer different sealant colours?
Most of the time, yes. We’ll explain which colours are available and agree one before we start.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How long does the job take?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on how many gaps there are. We will tell you when we quote.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you work in flats, HMOs and commercial buildings?
Yes. Occupied flats, HMOs, offices and schools are all fine. Early starts or out-of-hours work can be arranged where it’s needed.
Why act early in Belgravia
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing when the building is next checked. In a flat in Belgravia, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.
Why book with us
- Full insurance on every job
- Domestic, commercial and hotel work
- Anti-fungal silicone where joints get wet
- 20+ years of sealant experience

For landlords and businesses
Letting agents and landlords in Belgravia can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Different surfaces, different methods
Service penetrations
New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in.
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both, following the tested detail.
The process
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of gaps, and longer for a whole building. In Belgravia, 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.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Preparing for the visit
- Mention any tricky access
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in
