DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Fire rated sealant in Farthing Street, done properly
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate. Typical jobs include cracked or shrunken fire-rated sealant and standard silicone or caulk in a fire-stopping gap, on plasterboard & masonry, pipe & cable gaps and linear gaps.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that’s washroom resealing or fire-rated sealant around service openings. Where a building in Farthing Street needs to stay open, work can be planned outside normal hours.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Why deal with it now?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the work involved is often modest. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Farthing Street, the repair is bigger than a sealant job.
Combining jobs into one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.

Farthing Street: your questions answered
Can parking be tricky for a visit in Farthing Street?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you work for landlords with property near Orpington station?
Yes. We work for landlords and agents as well as householders. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or send us an email.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on how many gaps there are, including the preparation. We’ll confirm how long when we quote.
Can I choose the sealant colour?
Usually, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before work begins.
Do you work in flats, HMOs and commercial buildings?
Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Let us know the building’s hours and we’ll plan the work to suit.
What affects the cost of fire rated sealant
Jobs vary more than people expect. What affects the quote:
- Any mould that needs treating

- The type of sealant required

What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
What we need to know
To make quoting easier, let us know:
- A few pictures by email, if you can
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
- Where the property is

Fire rated sealant in Farthing Street: local notes
Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Farthing Street is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For landlords with property near Orpington station, any gap left by new services in shared walls should be closed with a fire-rated product. Schools such as Downe Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

Different surfaces, different methods
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run.
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.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Ask every contractor to reseal any fire stopping they disturb
- Check whether a sealant can be painted before decorating over it
- Keep the record of products and locations with your fire safety documents
- Check risers, ceiling voids and cupboards during building checks
Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
