What we do, step by step
On the day, we arrive at the time we’ve agreed, cover the area with dust sheets and masking, and set to work. The job typically takes around two hours. We clean up when we are done and tell you when it’s ready to use.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- We treat mould and dry the joint thoroughly.
- We fill the bath, or weight the tray, to open the joint.
- New mould-resistant silicone is applied and tooled neatly.
Preparing for the visit
- Keep a parking space free if you can
- Let us know which floor the room is on
- Keep children and pets away from the room on the day

Related advice
Your questions about bath resealing in The Rock
Do you seal over the old sealant?
We always remove the old sealant completely. Fresh silicone doesn’t stick to old.
Can tenants book a repair?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Can you repair something that’s been repaired before?
Most of the time. Tell us what was done before and we’ll plan for it.
Do the materials smell?
Some materials have a smell while they’re applied. It clears as the materials cure.
Do you cover The Rock?
We do. Repair technicians travel to The Rock from across the region, and the price is the same as everywhere else.
How long does a reseal take?
A bath or shower normally takes a couple of hours. Leave it to cure before use.
Will it make a mess?
Very little mess: we sheet and mask everything nearby, and we take our waste away with us.
Is a repair better than a new one?
In most cases, yes. A repair skips the removal, fitting and redecorating. We will be honest if it’s not worth it.
Do you need bath resealing in The Rock?
Sealant doesn’t last forever. Each shower leaves moisture and soap behind, which mould loves, and the joint flexes each time the bath fills.
Send us a photo if you notice any of these:
- Unsealed corners
- Old sealant that looks dirty
- Silicone smeared on tiles
- Black mould in the sealant

Landlords, agents and businesses in The Rock
For anyone letting property in or around The Rock, we can repair and quote for several addresses together. Send pictures for each one and we will come back with a combined price.
Rental properties take more wear, and replacing things at every changeover adds up. Repairing between tenants keeps the property presentable for less.
What bath resealing costs
Each job gets its own fixed price. This is what makes a difference:
- Doing more than one item at once
- How hard the colour is to match
- The type of damage
- Any earlier repairs that need removing first
The price reflects the work involved, not where you live. The full price is agreed before you book.
How to get a fixed quote
You can take the pictures on your phone, there’s no need for anything special. Just ensure we can see:
- Any earlier repairs or coatings
- A wider photo showing the entire bath or shower
- A close-up of the damage, in focus
- A coin or ruler next to the damage for scale
Pricing is simple: take a close-up of the damage and a photo from further back, send them over with your postcode, and we will reply with a fixed price. Quotes are free and you’re under no obligation.
How to look after the repair
How the surface is treated afterwards matters. Here’s what we suggest:
- Dry the seal after bathing
- Ventilate the bathroom well
- Give the seal a regular clean
- Air the room after use
Let it cure fully before using the bath or shower, normally about a day.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. There may be more going on, so we will tell you if it needs a builder or plumber.

Resealing in The Rock: why it matters
A reseal is one of the cheapest bathroom jobs there is, and it protects everything around the bath. Leaving failed sealant can let water cause damage that costs far more to fix. Most people are surprised how affordable a repair is, particularly next to the cost of replacement. Send pictures and we will give you the exact figure.

DIY kit or professional repair?
The difference between a kit and a professional repair is mostly in the preparation and colour. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, then guarantee it for a year.
We understand the appeal of fixing it yourself. The trouble is that kit repairs often look fine at first and then fail, and then the old filler has to be removed first.
