What happens if it’s left?
A leaking shower in a hotel room or flat above can damage the ceiling below. Then two rooms are out of action, not one. Resealing first is the smaller job. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in East End of London, the repair is bigger than a sealant job.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Commercial sealant in East End of London: local notes
London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. East End of London has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
If you look after a building such as St Mary and St Michael Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. Community buildings like Church of St Mary are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.

What we are called out for in East End of London
Heavy use means more movement: people of all sizes, daily cleaning and constant loading all work at the joint. If a tray flexes, the sealant around it splits.
Most people get in touch when they notice something like this:
- Tired sealant in let properties
- Shower leaks reaching the floor below
- Worktop sealant that has shrunk and stained
- Repeated reseals that don’t last
As a London address, East End of London can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
What your quote should include
- Whether they seal over old material or remove it
- When the joint can take water or movement
- Are they insured?
- How much experience the applicator has
Surface by surface
Welfare facilities
Welfare facilities, shower rooms and changing areas need to stay usable. Work can be split into sections.
Rental portfolios
Landlords and agents can have several properties resealed in one programme and each property booked in when it’s empty or convenient.
Aftercare tips
A little care helps the new joints last. We recommend:
- Give housekeeping the cure time for every room
- Encourage users to squeegee shower walls
- Schedule work around occupancy
- Include the silicone on your room checklists
Squeegees in guest and staff showers help: walls and trays dry faster, and so does the sealant.
A room that cannot be let or used is lost income. Catching faults early means they can be put right in a short window, instead of turning into a leak that closes the room.
Common questions in East End of London
Do you take on hotel work around East End of London?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Can parking be tricky for a visit in East End of London?
Parking in East End of London, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
How soon can a room be used after resealing?
Generally after around 24 hours. We give a cure time for each area.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can I choose the sealant colour?
Most of the time, yes. We will tell you which colours the right product comes in.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
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.
