Bathrooms and kitchens in Penge
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. London’s water is hard, which leaves limescale on sealant, grout and taps.
Schools such as Harris Primary Academy Crystal Palace are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. For landlords with property near Penge West station, mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.

Bathroom resealing for homes and businesses in Penge
We fill the bath before sealing it. A full bath sits slightly lower than an empty one, so the new joint is not pulled apart the first time it’s used. Quick jobs often leave it out, and it makes a real difference. We work on baths, wet rooms and shower trays & enclosures, and people most often call us about a joint torn by a bath that flexes and a messy, uneven bead from a previous reseal.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Penge, getting the joints right keeps water where it belongs and the room looking clean.
All our work comes with a one-year guarantee, wherever you are in Greater London.

What the job involves on each surface
Basins & vanity units
Basins take less water than showers, but the joint behind them is splashed every day. Old sealant there often goes black at the corners, so it’s cut out and renewed just like a bath joint.
Baths
A bath shifts slightly every time it’s filled, so it’s filled with water before the bead goes on. The joint is then laid with the bath at its lowest point and is not stretched when it’s used.
Penge questions
Can you help a landlord with a rental near Penge West station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Do you work in hotels near Penge?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Can you get rid of the black mould in my sealant?
Yes, we can. The old sealant comes out, the mould is treated, and we reseal with anti-fungal sanitary silicone.
How long does it take to reseal a bath or shower?
Allow a couple of hours for a single bath or shower. You’ll know how long to expect before we start.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
Can you reseal around my kitchen sink and worktop?
Yes. Worktops, sinks and splashbacks are all part of the job, in a kitchen-suitable sealant, matched to the worktop where it’s on show.
Looking after it afterwards
To keep the joints looking good and working properly:
- Wipe up water along the back of the worktop
- Open a window or run the fan so the room dries
- Squeegee the walls and tray after use
- Keep bottles off the sealant line
Wipe up standing water along the worktop joint and keep hot pans off the bead. The drier the joint stays, the longer it lasts.
A split bead lets water through every time the bath or shower is used. Over time that water reaches floors, walls and ceilings. Resealing early stops it.
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we do, step by step
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes two to three hours for a typical bath, depending on how much old sealant there is. In Penge, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First the area is protected and every bit of old sealant removed, including the film left on the tiles.
- We clean and degrease the joint and treat any mould.
- We let it dry fully and fill the bath with water before sealing.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- Finally we tidy up and explain the cure time before we leave.
How to prepare
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height

Advice
Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
What happens if it’s left?
Tired sealant isn’t a reason to replace a bath or shower. A new bead often brings the whole room back. If something else is wrong, we’ll tell you. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Penge, the repair is bigger than the sealant job would have been.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and send you a clear quote before we start.

What we are called out for in Penge
Mould is the reason many people want their sealant replaced. Steamy rooms that do not dry out keep the silicone damp for hours, and mould that has grown into the silicone generally will not clean off.
The problems people usually mention when they call include:
- Cracked, shrunken or lifting silicone
- Splits where the tray meets the wall
- Black spots spreading through the bead
- Smears of silicone across the tiles
If you live in an older home near Church of St John the Evangelist, walls and floors in older homes can move, and sealant and grout show it first.
