Bath & shower resealing (mastic) in Glandwr, Blaenau Gwent
Bath, shower and sink resealing with new mould-resistant silicone in Glandwr, carried out at your home and guaranteed for a year.
- Unsealed corners
- Leaks at the edges
- Gaps in the seal
Should I try a DIY kit first?
It’s natural to want to try a repair 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.
DIY kits are sold for most surfaces, and they can make a small mark look better. Where they fall down is colour and preparation: they come in a handful of shades, and if the surface isn’t prepared the repair won’t last.
Bath resealing in Glandwr 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. We regularly repair basins & vanity units, wet rooms and shower trays & enclosures, and common reasons people get in touch are silicone smeared on tiles and water getting behind the bath or tray.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Common questions in Glandwr
Can pets and children be at home?
Just keep them out of the work area. We will tell you when the room can be used again.
Why does my sealant keep splitting?
The bath or tray is probably flexing. If it keeps happening, the support may need fixing.
Do you work in Glandwr?
Yes. We cover the entire UK and travel to Glandwr and the rest of Blaenau Gwent. Send photos and we will quote, or call 0345 017 0787.
Can you quote from photos?
In nearly every case. We only ask to see it in person if the photos can’t show what we need.
How long will it take?
A bath or shower generally takes a couple of hours. It then needs time to cure.
Can you reseal over the old silicone?
We always remove the old sealant completely. New silicone will not bond to old.
Why does my sealant keep going mouldy?
Mould needs moisture. Ventilation and drying keep it clean longer.
Do you charge for travel?
There is no separate call-out charge. The fixed price covers the visit and the work.
Why reseal now?
A reseal is one of the cheapest bathroom jobs there is and protects the walls and floor. Leaving failed sealant can let water cause damage that costs far more to fix. Instead of hourly rates, we fix the price before we start. It depends on the damage, the material and access, and doing several items at once reduces it.
Why Glandwr clients choose us
- A year’s guarantee on all work
- One visit for most repairs
- Fixed prices from your photos
- No extra charge for your area
Read our prices page.
What bath resealing costs
There are no hourly rates or hidden extras. The price is based on:
- Unusual colours or finishes
- Access to the area
- Doing more than one item at once
- How much damage there is
A repair typically costs much less than people expect, particularly next to the cost of replacement. Send pictures and we will give you the exact figure.
Quotes from your pictures
When you take your photos, these tips help us give you a firm price:
- What it’s made of, if you know
- Daylight if possible, and no flash reflection
- Any earlier repairs or coatings
- The postcode, so we can plan the visit
No survey visit is needed: we price from photos. Use the quote form, or ring 0345 017 0787 to talk it through, and we will come back with a fixed figure.
Different materials, different repairs
Baths

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Air the room after use
- Clean the joints with a mild cleaner
- Reseal at the first sign of lifting
- Run the extractor fan during and after showers
Keep the room well ventilated, and dry the joints after bathing.
Don’t wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.
