Bath & shower resealing (mastic) in St Thomas, Devon
Bath resealing across St Thomas and nearby, normally in one visit and guaranteed for a year.
- Black spots in the silicone
- Old sealant that looks dirty
- Silicone smeared on tiles
Materials and what they mean for the repair
Shower trays
We put weight on a tray before sealing it, so the joint is at its widest.
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, with the joint fully dried first.
About our bath resealing in St Thomas
A proper reseal starts with removing every trace of the old silicone. New silicone won’t bond to old, which is why so many DIY reseals peel. Typical jobs include black mould in the sealant and stained silicone, on shower trays & enclosures, kitchen worktops & sinks and wet rooms.
The work is covered for a year after we finish. Just call us if there is a problem and we’ll sort it.

Why reseal now?
Sealing over old silicone is a false economy. It soon peels, and traps mould underneath. We remove the old sealant completely. A few things move the price: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Photos let us give you a fixed figure.

When we’d advise against a repair
Not everything can be repaired, and we will tell you before we start. Repairs will not solve:
- Movement in the bath or tray
- Tiles that move, until they’re refixed
- Gaps too big for silicone alone

Should I try a DIY kit first?
Kits are cheap and easy to find, but the repairs we redo most frequently are DIY ones that have discoloured or lifted. Doing it properly first is generally the cheaper route.
A DIY attempt is not a disaster. We take the old repair out and do it properly, so it will not stop us repairing it. Just mention it when you send photos, as it can add time.
Keeping it looking good
Looking after the surface is easy, and it makes a real difference:
- Give the seal a regular clean
- Use the extractor fan
- Keep the joints dry
- Don’t stand toiletries on the seal
Avoid scraping the joints, and keep shampoo bottles off the joints.
Do not wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.
How it works
A typical visit goes like this: we arrive on time, protect everything around the work area, do the job and tidy away. Plan for about two hours for a bath from start to finish. Before we go, we’ll explain when it can be used and how to care for it.
- The surrounding area is protected and the joints masked.
- Old sealant and residue are removed.
- We clean, treat and dry the joint.
- We run a continuous bead of new silicone.
- The bead is smoothed, the tape removed and the seal left to cure.
Getting ready for the visit
- Have a window or extractor fan available
- Mention any parking restrictions or tricky access
- Mention any earlier repairs or resurfacing

A repair normally costs much less than people expect, particularly next to the cost of replacement. Photos let us give you the exact figure.
