How we handle fire rated sealant in St Ann's
We do not assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on pipe & cable gaps, linear gaps and plasterboard & masonry, and common reasons people get in touch are seals cut through by electricians, plumbers or data installers and door frames with gaps between frame and wall.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In St Ann's, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Why deal with it now?
Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. In a flat in St Ann's, 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.
Doing several joints on one visit is normally more efficient than separate visits. We’ll give you a clear quote for the lot.
What you get with us
- Fully insured
- More than 20 years in sealant work
- An ARBOMaster approved applicator
- A 12-month guarantee on all work

Commercial buildings in St Ann's
St Ann's has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
St Ann's is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For site and facilities teams at buildings such as St Ann's CE Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Store the list of sealed gaps with your building paperwork
- Do not paint over fire sealant until it has cured
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Look in service cupboards and ceiling voids from time to time
Don’t 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.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Do you need fire rated sealant in St Ann's?
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Keep an eye out for these signs:
- Fire stopping disturbed by later work
- Sealant items on a fire risk assessment action list
- Gaps left after a refit or conversion
- Ordinary sealant used where a fire-rated product was needed
For buildings such as St Ann's Church, gaps around pipes and cables are worth checking after any building work there.

Common questions in St Ann's
Is parking an issue for fire rated sealant in St Ann's?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you work for landlords with property near Seven Sisters station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
How much does fire rated sealant cost in St Ann's?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Can you tell me which gaps need fire stopping?
No, we do not assess buildings. Once you have a specification or action list from your assessor or designer, we’ll quote for the sealant work on it.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
Where do you work from?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
How long will you be here?
Typically it takes a few hours for a handful of gaps, and longer for a whole building. Larger jobs naturally take longer, and we’ll say how long yours will take.
What we do, step by step
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. It normally takes from a few hours to a few days, depending on the number of gaps and the access. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in St Ann's. It helps if you can point us to a visitor permit or a bay close to the door.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can
