- Water getting behind the bath panel
Bathroom resealing in Bow, done properly
We fill the bath before sealing it. The weight settles the bath to its lowest point, so the new joint isn’t pulled apart the first time it’s used. Quick jobs often leave it out, and it makes a real difference. We work on kitchen worktops & upstands, baths and basins & vanity units, and common reasons people get in touch are water getting behind the bath panel and new sealant laid over old sealant that is now lifting.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Bow more than a cosmetic job.
All of our work is guaranteed for twelve months, in Bow and everywhere else we cover.

Bow homes and their sealant
London’s water is hard, which leaves limescale on sealant, grout and taps. 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.
Homes close to St Paul Old Ford include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. As a London address, Bow can be tricky for parking: let us know about parking bays, permits or a driveway.
Bow is about 1 mile south-east of Hackney, in Greater London. Bow gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. We cover 764 towns and villages across Greater London.

When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- A tray or bath that is cracked through
- Water coming from the plumbing rather than the joint
- Water getting in through the grout rather than the sealant
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before you book.

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 we find a deeper problem, you’ll hear it from us. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Bow questions
Can worn sealant in a flat in Bow cause a leak downstairs?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
Can you help a landlord with a rental near Hackney Wick 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.
Which products 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.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How do I get a quote for bathroom resealing in Bow?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or drop us an email with a short description of the job.
Can you get rid of the black mould in my sealant?
Yes. Once mould has grown into the silicone, it usually can’t be cleaned out for good, so the bead comes out, the joint is treated and new anti-fungal silicone goes in.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Signs you need bathroom resealing in Bow
Not every tube in the shop is meant for a shower. Decorators’ caulk and all-purpose sealants aren’t made for constant wetting, so they crack, discolour or grow mould quickly. Wet areas call for a sanitary silicone with an anti-fungal additive.
These are the problems we are asked about most:
- Leaking joints on a shower screen
- New sealant laid over old sealant that is now lifting
- Damp behind the bath or under the tray
- A joint torn by a bath that flexes
Letting a property close to Hackney Wick station? Then fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.
Before booking anyone
- How long the guarantee is
- What happens if the job turns out different
- Whether the sealant suits the joint
- Whether you can choose the colour
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep scourers and sharp tools away from the bead
- Let new sealant cure fully before it gets wet
- Keep an eye on the corners, where splits start
- Clean with a mild bathroom cleaner and a soft cloth
Wipe up standing water along the worktop joint and keep hot pans away from the silicone. The drier the joint stays, the longer it lasts.
Mould that starts as a few spots spreads through the bead. When it has grown right through, it rarely cleans out. Replacing the sealant early keeps the job small.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes around two hours for one bath or shower, longer for a whole bathroom and we leave things clean and tidy. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We protect the area and cut out all of the old sealant, including the film left on the tiles.
- The joint is cleaned, degreased and treated for mould.
- Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
- New anti-fungal silicone goes on in a colour to suit and is tooled to a clean finish.
- We clear away and tell you when it can get wet, generally after around 24 hours.
Getting ready for the visit
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
