About our remedial sealant in North End
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. Only then can new sealant bond. Common call-outs are for sealant peeling off a dusty or damp surface and repeat leaks from the same joint, on leaking tray & enclosure joints, botched or over-sealed joints and mouldy bath & shower sealant.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In North End, that’s a good reason to put tired sealant and grout right early.
Every job is covered by a 12-month guarantee.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

What else we do in North End
Why it’s worth doing now in North End
Stripping out botched sealant adds time to a reseal, but not by much: it takes a few hours for most joints, depending on how much old sealant has to come out. Compared with chasing the same leak every few months, it’s time well spent. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in North End.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.
Why book with us
- Colour agreed with you before any work starts
- Fully insured
- Experience in homes, commercial sites and hotels
- A choice of colours where the product allows

Landlord and commercial work in North End
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Remedial sealant around North End
There are hotels and other places to stay in and around North End. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. London’s water is hard, which leaves limescale on sealant, grout and taps.
North End is in London, so parking needs planning: let us know about parking bays, permits or a driveway. In the older streets around Church of St Alban the Martyr, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For landlords with property near Hampstead Heath station, botched sealant from a previous quick fix is easier to strip out between tenants.

North End: your questions answered
I live in a flat in North End. Can a failed seal leak into the flat below?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
Is parking a problem for a job in North End?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
What if resealing won’t fix my leak?
We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.
Do you come to North End?
Yes. We are based in Crawley and work across South East England, London and Scotland, North End included.
Someone sealed over the old bead. Can you fix it?
Yes. Both layers come out; over-sealing fails because silicone won’t bond to silicone.
Can you match the sealant colour?
Yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
The process
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a typical bath or shower, longer where several layers have been applied. In a London area like North End, 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.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
How to prepare
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
How to get a quote
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand.

How to look after the new joints
To keep the joints looking good and working properly:
- Find out why the sealant failed first
- Keep the room well ventilated
- Don’t add new sealant on top of old
- Act on a lifting corner right away
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
Signs to act on: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.
