Bath resealing in Bishop's Castle without replacing anything
Preparation is everything in a reseal: every bit of old silicone out, mould treated, the joint clean and dry. Only then does the new sealant go on, as one neat, continuous bead. Whether it’s silicone smeared on tiles and gaps by the taps, we can typically put it right, on baths, wet rooms and basins & vanity units alike.
Every job is backed for twelve months in Bishop's Castle and everywhere else. If something goes wrong with the work, we come back.

Common problems we fix in Bishop's Castle
Most reseals are because of black mould. It grows into the silicone, so cleaning only removes the surface.
Look out for any of the following:
- Black spots in the silicone
- Water getting behind the bath or tray
- Unsealed corners
- An untidy old seal

Can I fix it myself?
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.
DIY kits are sold for most surfaces, and they can tidy up a tiny mark. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.
FAQs for Bishop's Castle
Do you work for landlords and businesses?
We do, regularly. We can quote for several properties together and work between tenancies.
Do you cover the entire of Shropshire?
Across the UK, and that includes Bishop's Castle. Our prices are the same everywhere.
When can you do it?
That depends on our diary for your area. Send pictures with your postcode and we will reply with the earliest dates.
My seal keeps tearing. Why?
Usually because the bath or tray moves, or it was sealed with the bath empty. We seal baths full of water.
How long does a reseal take?
Around two hours for a bath, then it needs to cure.
Is repairing better than replacing?
Generally, yes. Replacement brings removal, refitting and making good, which a repair avoids. We’ll be honest if it’s not worth it.
Is there a guarantee?
Every repair comes with a one-year guarantee. We will explain what it covers when we quote.
Is it OK to have pets in the house?
We ask you to keep children and pets out of the room while we work and until it has cured. Everywhere else in the home is fine.

Advice
Looking after it afterwards
After the repair has cured, a few habits help it last:
- Air the room after use
- Use the extractor fan
- Reseal at the first sign of lifting
- Wipe the joints dry after use
Keep the room well ventilated, and dry the joints after bathing.
Black mould in sealant is not just unsightly; it shows moisture is getting in. Resealing early keeps water out of the walls and floor.
Prices and what affects them
There are no hourly rates or hidden extras. The price is based on:
- Access to the area
- How many items we do on one visit
- Previous DIY repairs that have to come out
- The material and finish
Compared with replacing, repairing typically costs far less, because nothing has to be taken out, refitted or made good. Your fixed quote shows exactly what’s included.
Getting a price from pictures
Before you send pictures, a few simple things make all the difference:
- Where you are, by postcode
- Any earlier repairs or coatings
- A close-up of the damage, in focus
- A wider photo showing the whole bath or shower
Most clients in Bishop's Castle get their price from photos. Add a line about what happened and your postcode, and we’ll send back a fixed quote and some dates.
What your bath or shower is made of matters
Baths
Baths are resealed with water in them, so the joint is at its widest.
Shower trays
We put weight on a tray before sealing it, so the joint is at its widest.
Honest limits
A few problems are outside what a surface repair can do:
- A bath or tray that moves, until its support is fixed
- Gaps so wide they need filling or trims before sealing
- Loose tiles, which need refixing first
If in doubt, send pictures and we’ll say what we think before booking.
