Bath resealing at your home in Treswithian
We reseal baths, shower trays, basins and worktops, with mould-resistant sanitary silicone. A typical reseal takes a couple of hours, then it needs to cure. We regularly repair shower trays & enclosures, basins & vanity units and wet rooms, and the jobs we see most are an untidy old seal and gaps in the seal.
You are covered for a year from the day of the repair. If anything is not right, ring us and we’ll sort it.

Landlords, agents and businesses in Treswithian
Letting agents frequently send us pictures straight from the inventory. That means we can quote before you even visit the property, and we can arrange access with the tenant directly if that helps.
We carry out planned and one-off repairs for housing associations and facilities teams in Cornwall and across the UK. Repairing in place avoids the disruption of a replacement, which matters when someone is living in the home.
What happens on the day
We begin by going over the job with you. Next, we cover and mask everything nearby and the work begins. It normally takes about two hours for a bath, and we’ll tell you if anything changes.
- The old silicone is cut out completely.
- Residue is removed and the joint cleaned.
- We treat mould and dry the joint thoroughly.
- The bath is filled with water, or weight put on the tray.
- We apply fresh mould-resistant silicone and tool a neat bead.
How to prepare
- Clear toiletries, mats and anything else from around the area
- Mention any parking restrictions or tricky access
- Keep children and pets away from the room on the day
Getting a price
A quote takes minutes to ask for: take one close-up and one wider shot of the bath or shower, add your postcode and send them over. You will get a fixed quote, not an estimate.

Materials and what they mean for the repair
Baths
Baths are resealed with water in them, to open the joint fully.
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.
Is resealing worth it?
Resealing is a small job. Leaving split or mouldy sealant lets water get behind the bath or tray, which costs far more to put right. Rather than charging by the hour, we fix the price before we start. Damage, material and access decide it, and combining items on one visit brings it down.

Your questions about bath resealing in Treswithian
How quickly can you book me in?
That depends on our diary for your area. We will offer you dates when we send your quote.
What happens after I send photos?
You get a fixed quote and available dates. If we need another angle, we’ll ask.
What happens if you find more damage?
If we find something the photos didn’t show, we explain it first. The price only changes if you agree.
Do you seal over the old sealant?
No, we never seal over old silicone. The old sealant is cut out and the joint cleaned and dried.
Can pets and children be at home?
We ask you to keep children and pets out of the room while we work. Everywhere else in the home is fine.
Is there any odour?
Expect a mild smell while we’re working.
Why does the silicone keep cracking?
Typically because the bath or tray moves. We seal baths full of water.
Can you price it without visiting?
Yes, almost always. Clear pictures let us give you a fixed quote without visiting.

What bath resealing costs
Prices are worked out job by job, from your photos. What matters most is:
- The type of damage
- How much damage there is
- Previous DIY repairs that have to come out
- The colour and finish to match
It helps to know what pushes a price up or down: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Send pictures and you will get a fixed figure.
How to get a fixed quote
Most quotes are done from photos alone. To help us price it:
- Any details about the material
- Any earlier repairs or coatings
- Something in shot to show the size
- Natural light rather than flash
There’s no need for us to visit first. Nearly every job can be priced from pictures: we need a close-up, a wider picture and your postcode, and we’ll reply with a fixed quote.
Should I try a DIY kit first?
If you do try a kit, read the instructions carefully and work on a clean, dry surface, and do not use it until it has fully cured. If it does not work out, we can still repair it properly.
You can buy a DIY kit for most repairs, and they can make a small mark look better. The trouble is colour and preparation: they come in a handful of shades, and if the surface is not prepared the repair will not last.
How to care for the repair
Most damage we see is avoidable. A few tips:
- Keep the joints dry
- Let steam out after showers
- Replace the seal when mould sets in
- Run the extractor fan during and after showers
Don’t scrape the sealant with anything sharp, and keep shampoo bottles off the joints.
Black mould in sealant is not just unsightly, it’s a sign moisture is sitting in the joint. An early reseal keeps water where it belongs.
