Regrouting in Wapping, done properly
Our applicators rake out the old grout to an even depth, taking care not to chip the tile edges. After vacuuming, new grout goes in and the tiles are wiped clean, and the corners get fresh silicone. If you’re dealing with cracked or crumbling grout lines and corners filled with grout instead of silicone, we can help.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. That makes worn sealant and cracked grout in Wapping more than a cosmetic job.
Each job carries a 12-month guarantee.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
What affects the cost of regrouting
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- How easy the joints are to reach
- The type of sealant required
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
What we need to know
You don’t need to know the technical terms. Just tell us:
- What’s wrong with the joints now
- Any access issues, like height or stairs
- Roughly how big the job is
- The type of property
Every job is quoted individually, so the first step is telling us about yours. Simply call 0345 464 0079 or email us and describe the job, and pictures are welcome.
Bathrooms and kitchens in Wapping
London’s water is hard, so limescale builds up on sealant, grout and fittings. In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early.
As a London address, Wapping can be tricky for parking: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as St Mellitus College, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

When to call us in Wapping
Harsh cleaners and scrubbing wear grout away. Some bleaches and acid descalers break grout down with repeated use, until the joints are rough and low.
If you can see any of these, it’s time to have the joints looked at:
- Stained grout that cleaning won’t shift
- Grout washed out of a shower
- Grout that’s cracking and breaking up
- Grout that makes sound tiles look old
Letting a property close to Wapping station? Then stained grout drags a rental down, and regrouting between lets puts that right.
Before you book anyone
- Is VAT in the price?
- How the joint is cleaned and prepared
- How hidden problems are handled
- How long to leave it before use
What happens if it’s left?
Cleaning products may brighten grout for a time, but stains and mould that have soaked in tend to return. New grout, with silicone in the corners, deals with the cause. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Rinse soap off the tiles after each shower
- Look at the sealant in the corners now and then
- Clean with a soft brush, not anything metal
- Keep the fan on after showering
Use a gentle cleaner on the grout and a soft brush. Keep harsh bleach and acid limescale removers away from it, as they can break grout down.
Tiles can come away if failed grout is left. By then, new grout alone isn’t enough so early action pays.
