About our bathroom resealing in Coldharbour
Across Coldharbour, the joints we reseal are the ones that fail in any home: bath edges, tray joints, basin backs and kitchen upstands. Every joint is cut out, cleaned and left dry before it’s resealed. If you are dealing with lumpy, uneven sealant from a DIY attempt and leaks into the floor or ceiling below, we can help, on baths, shower trays & enclosures and wet rooms alike.
Hard London water leaves limescale on sealant, grout and taps alike. In Coldharbour, bathroom resealing is as much about a room looking cared for as about keeping water out.
Each job carries a 12-month guarantee.

Coldharbour questions
Is parking a problem for a job in Coldharbour?
Parking in Coldharbour, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Could a tired shower seal in my Coldharbour flat affect the neighbours below?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What should I tell you?
Tell us what needs doing and where, with photos by email if possible. If we need more, we’ll ask.
Can tenants book the work?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Can I choose the colour of the sealant?
White, clear and a range of colours are available. Where the joint is on show, we match it to the surface.
Do you work for landlords and businesses?
Yes, often. Several properties can be quoted together, and between tenancies is a good time for the work.
What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take around two hours for one bath or shower, longer for a whole bathroom. In a London area like Coldharbour, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We cover the area around the joints we’re working on.
- We cut away the old sealant and clean off what’s left.
- Mould is treated, then the joint is left to dry thoroughly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Preparing for the visit
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
- Clear items away from the joints we’re working on

Advice
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
What sealant work can’t fix
In fairness, there are a few things sealant won’t fix:
- A tray that rocks until it’s re-bedded
- A leaking waste, trap or valve
- A cracked shower tray or bath (that needs repair or replacement)
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Surfaces we seal
- Kitchen worktops & upstands
- Basins & vanity units
- Shower trays & enclosures
- Baths
- Sinks & splashbacks
- Wet rooms
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
When to call us in Coldharbour
Not every tube in the shop is meant for a shower. Acrylic caulk and general-purpose sealants are not designed for a joint that’s wet every day, so they stain, crack or go mouldy before long. A bathroom joint needs anti-fungal sanitary silicone.
It’s worth asking for a quote if you see:
- Water getting behind the kitchen upstand
- Water escaping at the shower enclosure
- Lumpy, uneven sealant from a DIY attempt
- A bead that has pulled away from the tiles
Schools such as Mottingham Primary School are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
Before you book anyone
- Is the old sealant removed completely?
- Are they insured?
- Is VAT in the price?
- How much experience the applicator has
Bathroom resealing around Coldharbour
London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early.
As a London address, Coldharbour can be tricky for parking: let us know about parking bays, permits or a driveway. If you let a flat or house near Mottingham station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Check the joints every few months for splits or lifting
- Keep the fan on for a while after bathing
- Wait for the cure time we give you
- Avoid abrasive pads on the sealant
Treat the new bead gently when you clean: warm soapy water and a soft cloth do the job. Avoid scouring pads and anything sharp, because a damaged bead gives mould a foothold.
Worktop joints fail quietly. Splashes run behind the back edge and soak into the worktop, where it can make the board swell. Resealing before that happens protects the worktop.
