Common questions in Lessness Heath
Is Lessness Heath in your area for fire rated sealant?
Yes. We work across London and the South East, and Lessness Heath is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Can parking be tricky for a visit in Lessness Heath?
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 it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Is intumescent sealant the same as fire-rated sealant?
Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, large or small.
How do I get a quote for fire rated sealant in Lessness Heath?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or drop us an email with a short description of the job.
Do you seal gaps around fire door frames?
Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

Surface by surface
Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in with backing where the detail needs it.
Door frames
Our work is the joint between frame and wall. The door leaf, its seals and closer need a door specialist and we will mention anything we notice.

What happens if it’s left?
Squirting in whichever sealant is nearest doesn’t make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

When it isn’t the sealant
A few problems are outside what sealant work can do:

- Big openings where sealant alone isn’t the tested solution
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on how many gaps there are, and the area is left clean.

- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.

Advice
Looking after it afterwards
To keep the joints looking good and working properly:
- Report cracked or damaged seals as soon as you notice them
- Check whether a sealant can be painted before decorating over it
- Keep photos of seals that will be hidden
- Ask every contractor to reseal any fire stopping they disturb
File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
What fire rated sealant looks like in Lessness Heath
Commercial buildings in London often have strict access rules and limited loading, 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 work to the specification you’re given, installing the product to its tested details.
If you let a flat or house near Belvedere station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For buildings such as Parish Church of All Saints, older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as Lessness Heath Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.
