How we handle fire rated sealant in Welling
We can work through a building room by room or floor by floor, with each location and product recorded. That record is useful for your files and for whoever looks at the building next. We are often asked to deal with ordinary sealant used where a fire-rated product was needed and holes left by a change of layout, on flats & HMOs, pipe & cable gaps and linear gaps.
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 Welling.
Your job is guaranteed for a year, as with all our work.

Signs you need fire rated sealant in Welling
Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
Common reasons people contact us include:
- Ordinary sealant used where a fire-rated product was needed
- Gaps where walls meet ceilings or slabs
- Damaged fire sealant left by other trades
- New service routes left unsealed after building work
Community buildings like St John's Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.
What your quote should include

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
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 fails, we can still redo it.
Common questions in Welling
Can you help a landlord with a rental near Welling station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Is parking an issue for fire rated sealant in Welling?
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.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one of the options. We use whichever the specification and tested details call for.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
What do you need from me for a quote?
A short description and the location. We’ll ask anything else we need to know.
Do you come to Welling?
Yes. We cover Welling and the rest of Greater London. For a quote, phone 0345 464 0079 or drop us an email.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Include fire stopping when you schedule refits
- Check risers, ceiling voids and cupboards during building checks
- Photograph sealed gaps before they’re covered up
- Don’t paint over fire sealant until it has cured
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded so the item can be closed.

What fire rated sealant looks like in Welling
Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed. 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, 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.
For landlords with property near Welling station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Schools such as Danson Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

What happens if it’s left?
Squirting in whichever sealant is nearest does not make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. In a flat in Welling, 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.
