DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

What we do, step by step
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to several days, depending on the number of rooms. In Nunhead, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- First we visit and agree the scope, the sequence and the working hours.
- Every area is sheeted and the old silicone stripped out.
- Joints are cleaned, treated for mould and dried.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- We check every room and give its cure time for housekeeping.
Getting ready for the visit
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can

What else we do in Nunhead
What the job involves on each surface
Office washrooms & kitchens
Long vanity tops have joints that hold water and grime. We renew it in one tidy, continuous bead.
Student & care accommodation
Halls and care homes often have many near-identical bathrooms. We agree a programme and work through them steadily.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Pass on the cure time to whoever cleans the rooms
- Log resealing so you know what’s due
- Act on lifting sealant before it leaks
- Keep extractor fans working and serviced
We give a cure time for every area we finish, which is normally around 24 hours. Pass it on to housekeeping or cleaners so nobody showers or cleans the joint too early.
Watch for the warning signs: mould, splits, peeling corners or water marks downstairs. Any of these means the joints need attention.
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Poor ventilation that keeps bringing mould back
- A shower tray, bath or basin that’s cracked or broken
- Assessing what fire stopping a building needs
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.

Why it’s worth doing now in Nunhead
Sealant is easy to forget until an audit or inspection is due. Booking it in good time leaves room for the cure time before the visit, without a last-minute rush. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.

When to call us in Nunhead
Commercial bathrooms get far more use than domestic ones, and they’re cleaned with strong products every day. So the silicone ages faster than it would at home.
If you can see any of these, it’s time to have the joints looked at:
- Rental bathrooms that need resealing between tenants
- Leaking joints in shower rooms and changing areas
- Failed joints in office kitchens and tea points
- Leaks from showers into rooms or ceilings below
If you look after a church, hall or community building such as Saint Antony with Saint Silas, its kitchen and washroom sealant needs looking after like anywhere else.

Commercial buildings in Nunhead
London’s water is hard, so limescale builds up on sealant, grout and fittings. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
For site and facilities teams at buildings such as Ivydale Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. Nunhead is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
