Common questions in Ladywell
Is parking an issue for fire rated sealant in Ladywell?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you work for hotels and guest houses in Ladywell?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Will you assess my building’s fire safety?
No, assessment isn’t something we do. Once you have a specification or action list from your assessor or designer, we will quote for the sealant work on it.
Is intumescent sealant the same as fire-rated sealant?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all.
What does fire rated sealant cost?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email and tell us what needs doing and where.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
Fire rated sealant for homes and businesses in Ladywell
We can work through a building room by room or floor by floor, noting the locations and products as we go. That record is useful for your files and for whoever looks at the building next. If you have seals cut through by electricians, plumbers or data installers and gaps flagged on a fire risk assessment, we can help, on pipe & cable gaps, linear gaps and flats & HMOs alike.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that is washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Ladywell cannot close.
All of our work is guaranteed for twelve months.

What fire rated sealant looks like in Ladywell
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. Ladywell has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Community buildings like Church of St Mary the Virgin are part of the picture too: gaps around pipes and cables are worth checking after any building work there. If you look after a building such as St Mary's Lewisham Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment.
Ladywell is about 1 mile south-east of New Cross, in Greater London. From the centre of Ladywell to the outskirts, fire rated sealant is available for homes and businesses alike, from flats and houses to offices and hotels. Our Greater London coverage runs to 764 places, Ladywell among them.
Work in SE13, SE6 and SE4 works the same way as everywhere else we cover. Whether your property is on Veda Road, Roxley Road and Honley Road or a nearby road, we can help. If you’re just outside Ladywell, we cover Lewisham (1 mile north-east), Crofton Park (1 mile west), Hither Green (1 mile east), Brockley (1 mile west) and Catford (1 mile south). We also work in nearby towns such as London (5 miles north-west), City of Westminster (7 miles north-west), Marylebone (7 miles north-west), Kensington (9 miles west), St Pancras (7 miles north-west) and Shoreditch (6 miles north-west).
What’s near Ladywell
We work in homes and buildings around The London & Rye pub, Trinity Church of England School and Ladywell Fields and the streets around them. There’s a railway station in Ladywell itself: Ladywell station. A little further out are Greenwich Castle (1.8 miles north) and University Hospital Lewisham (within half a mile north-west). Open spaces near Ladywell include Brookmill Road Local Nature Reserve and Knight's Hill.
What happens if it’s left?
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now means you can show the action was taken. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Ladywell, the repair is bigger than a sealant job.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The process
On the day, we look over the joints with you first. Surfaces next to the work are protected before work begins. The work usually takes anything from a few hours to several days, depending on how many gaps there are. In a London area like Ladywell, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- 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 gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used.
Before we arrive
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
- Let us know about parking restrictions

Advice
Common problems we fix in Ladywell
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.
It’s worth asking for a quote if you see:
- Sealant items on a fire risk assessment action list
- Gaps where walls meet ceilings or slabs
- Door frames with gaps between frame and wall
- Open holes round services passing through fire walls
Rented homes near Ladywell station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.
What to look for in a quote
- How hidden problems are handled
- Is the old sealant removed completely?
- How much experience the applicator has
- What the cure time is
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Get damaged fire seals looked at promptly
- Ask every contractor to reseal any fire stopping they disturb
- Plan fire stopping into any work that goes through walls or floors
- Photograph sealed gaps before they’re covered up
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
