Bath & shower resealing (mastic) in Castletown, Dorset
Bath, shower and sink resealing with new mould-resistant silicone at your home in Castletown, with a one-year guarantee on every repair.
- Missing sealant behind the taps
- Silicone smeared on tiles
- Black spots in the silicone
Aftercare tips
Much of the damage we repair could have been avoided. A few tips:
- Replace the seal when mould sets in
- Keep the joints dry
- Clean the joints with a mild cleaner
- Don’t stand toiletries on the seal
Use the extractor fan, dry the joints after bathing, and clean them regularly with a mild cleaner to slow mould growth.
Damp below or loose tiles need checking quickly. It may be more than a reseal, and we’ll say if you need a builder or plumber.
Bath resealing in Castletown, done in place
Resealing is one of the simplest ways to protect your bathroom. Old, split or mouldy sealant lets water get behind the bath or tray, and resealing puts a stop to that. Whether it’s gaps in the seal and unsealed corners, we can help, on wet rooms, baths and shower trays & enclosures alike.
You get a one-year guarantee, the same in Castletown as everywhere else we work.

How we price bath resealing
There’s no area surcharge for Castletown. What changes the price is:
- Where the damage is and how we get to it
- Any earlier repairs that need removing first
- Doing more than one item at once
- The material
Every job is a little different, so each one is priced on its own. The size and type of damage, the material and access all play a part, and combining jobs on one visit brings the cost down.
Quotes from your photos
When you take your photos, a few simple things make all the difference:
- A clear, close picture of the problem area
- Something in shot to show the size
- Any details about the material
- Your postcode, so we can check dates
You don’t need a survey visit. Nearly every job can be priced from photos: send a close-up, a wider shot and your postcode, and we’ll reply with a fixed quote.
Questions from Castletown
Is there a call-out fee?
There’s no separate call-out charge. Your fixed price includes everything.
How long does silicone take to cure?
Usually after around 24 hours. We will tell you the exact time.
Will there be a smell?
There can be some smell while we work, which is why we ventilate. It fades as everything cures.
Will the price change on the day?
If we find something the pictures didn’t show, we explain it first. You decide whether to go ahead.
What areas do you cover?
Everywhere in the UK, Castletown included. There is no extra charge for travel.
It’s been repaired before. Can you still fix it?
Most of the time. Let us know what was used before.
Do you seal over the old sealant?
Never over old. It’s removed, cleaned off and the joint dried first.
Do I need to be at home?
Yes. The technician needs access to the room for the visit, at a time we agree with you.
Landlords, agents and businesses in Castletown
We carry out planned and one-off repairs for housing associations and facilities teams in Dorset and across the UK. Repairing in place avoids the disruption of a replacement, which matters when someone is living in the home.
Rental properties take more wear, and replacing things at every changeover adds up. A repair between tenancies is a cheaper way to keep the property in good order.
DIY kit or professional repair?
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 frequently lifts.
A kit can be fine for a tiny mark out of sight. For damage in plain view, cracks, holes or rust, or coloured finishes, a professional repair is worth it.
Common problems we fix in Castletown
Poor ventilation speeds things up: damp hangs around, and mould takes hold.
Common reasons people in Castletown contact us include:
- Damp near the bath
- Missing sealant behind the taps
- Discoloured, yellow sealant

What to look for in a quote

- What happens if they find more damage
- Whether the colour is mixed to match
- How to look after the finish
When we’d advise against a repair
We’d rather lose a job than do one that will not last, so these are the limits:
- Hollow or loose tiles
- Gaps so wide they need filling or trims before sealing
- Rotten walls or floors behind the bath
Send us photos and we will tell you honestly before you book.

Baths
We fill the bath before sealing, to open the joint fully.
Shower trays
We put weight on a tray before sealing it, for the same reason.
