Remedial sealant in Grange Park, done properly
If a joint has been resealed and is leaking again, it’s worth a proper look. It helps to have photos when you ring 0345 464 0079 or send us an email, and say how long ago it was last done. If you are dealing with smears and lumps from a botched reseal and worktop sealant that has shrunk and split, we can help.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Grange Park, that’s a good reason to put tired sealant and grout right early.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Leave it or put it right?
Mould under a bead can’t be reached by cleaning. Removal is the only way to get at it. In a flat in Grange Park, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear price before work begins.

Questions from Grange Park
Is parking a problem for a job in Grange Park?
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.
Can you help a landlord with a rental near Grange Park station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Where are you based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Someone sealed over the old bead. Can you fix it?
Yes. Each layer is cut out and the residue cleaned off, then the joint is resealed once.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Does remedial work come with a guarantee?
Yes. You get our 12-month guarantee.
What remedial sealant looks like in Grange Park
London’s water is hard, so limescale builds up on sealant, grout and fittings. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early.
If you let a flat or house near Grange Park station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For an older house near a landmark such as Church of St Mary Magdalene, walls and floors in older homes can move, and sealant and grout show it first.

What we are called out for in Grange Park
Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
Keep an eye out for these signs:
- Black mould underneath the bead
- Sealant that came away because the surface wasn’t prepared
- Caulk or the wrong sealant used in a wet area
- Over-sealed joints coming away
Managing a site like Grange Park Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What your quote should include
- When the joint can take water or movement
- How the joint is cleaned and prepared
- Whether they seal over old material or remove it
- The length of the guarantee
What happens on the day
At the end, we look at the finished work together. The work normally takes a few hours, depending on how many layers have to come out, depending on the size of the job. In Grange Park, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.
Getting ready for the visit
- Clear the area around the work
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work

Advice
Landlord and commercial work in Grange Park
Housing providers, facilities teams and property managers book us too in Grange Park and across Greater London. Several sites can be quoted together, and we are fully insured for the work.
We work for landlords and agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
How the job changes by surface
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out.
What we cannot put right
Before booking, it’s worth knowing the limits:
- Failed tanking or loose tiles behind the sealant
- A tray or bath that is cracked
- A bath, tray or worktop that moves until it’s properly fixed
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.
Where we work in Grange Park
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Failed movement joints
- Expansion joints
- Leaking tray & enclosure joints
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Have loose fittings fixed before resealing
- Deal with small splits early
- Always have old sealant cut out, not covered
- Keep an eye on the ceiling below the bathroom
If the joint ever needs renewing, have it cut out, not sealed over. New silicone doesn’t bond to old, so the old bead should always come out first.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
