How we handle bath resealing in Sydenham
We cut out all of the old sealant, treat any mould, and reseal with new mould-resistant silicone. We do this for baths, showers, sinks and worktops, including the awkward bits behind the taps. Whether it’s silicone smeared on tiles and old sealant that looks dirty, we can help, on basins & vanity units, baths and shower trays & enclosures alike.
You are covered for a year from the day of the repair. Just call us if there is a problem and we’ll come back.

How to look after the repair
A little care keeps the finish looking good. Our advice:
- Store bottles on a shelf
- Wipe the joints dry after use
- Give the seal a regular clean
- Air the room after use
Use the extractor fan, wipe the joints dry after use, and clean them regularly with a mild cleaner to slow mould growth.
Reseal before water gets in. Gaps or lifting edges mean it needs doing.
Different materials, different repairs
Baths
We fill the bath before sealing, so the joint is at its widest.
Shower trays
Trays are sealed with weight on them, for the same reason.

Compared with repairing water damage, resealing is cheap. It’s a quick job that protects your walls and floors. We don’t add extras on the day. The price we quote from your pictures is the price you pay, and if the damage turns out to be different, we discuss it before starting.

Sydenham questions
What happens once I’ve sent photos?
You will get a fixed quote back. There is no obligation to book.
Can I get a quote without a visit?
Typically, yes. Clear pictures let us give you a fixed price without visiting.
Can you repair something that is been repaired before?
In most cases. The old repair comes out first.
How long before I can shower?
Normally about a day later. We will tell you the exact time.
How long does a reseal take?
Usually a couple of hours, then it needs to cure.
Can you reseal over the old silicone?
No, we never seal over old silicone. It’s removed, cleaned off and the joint dried first.
Why does mould come back so fast?
Mostly moisture and poor ventilation. We use mould-resistant silicone, and ventilation helps it last.
Why does the silicone keep cracking?
Movement is the usual cause, or it was sealed with the bath empty. We seal baths full of water.

What bath resealing costs
Quotes are free and the price is fixed. What we look at:
- Where the damage is and how we get to it
- Whether it’s a chip, crack, burn or wear
- The colour and finish to match
- Previous DIY repairs that have to come out
Instead of hourly rates, we price the entire job up front. It depends on the damage, the material and access, and doing several items at once reduces it.
How to get a fixed price
Before you send photos, a few simple things make all the difference:
- A coin or ruler next to the damage for scale
- Where you are, by postcode
- A close-up of the damage, in focus
- A picture taken from further back
Call 0345 017 0787 or use the quote form. With one close-up and one wider picture, we can give you a fixed price.
Should I try a DIY kit first?
The difference between a kit and a professional repair is mostly in the preparation and colour. We prepare the area properly, mix the colour on site and polish the finish to match, and the work is guaranteed.
You can buy a DIY kit for most repairs, and they can tidy up a tiny mark. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler frequently lifts.
Landlords, agents and businesses in Sydenham
We carry out planned and one-off repairs for housing associations and facilities teams in Greater London and across the UK. Repairing in place avoids the disruption of a replacement, which matters when someone is living in the home.
For developers and builders, we fix damage before handover. We can visit several plots in one trip.
Common problems we fix in Sydenham
Even good sealant eventually discolours, especially in a busy family bathroom. Steam, soap and movement all wear it down.
The most common problems we are called about are:
- Mould you cannot clean out
- Silicone coming away from the tiles
- Leaks at the edges
- Silicone smeared on tiles
