Bath & shower resealing (mastic) in Garth, Newport
Fixed-price bath resealing in Garth and the surrounding area, done in a single visit in most cases and guaranteed for a year.
- Sealant that’s split or lifting
- Black spots in the silicone
- Unsealed corners
Bath resealing at your home in Garth
The key to a good reseal is getting all of the old silicone out. Fresh sealant does not stick to old, which is why so many DIY reseals peel. We work on wet rooms, basins & vanity units and shower trays & enclosures, and people most often call us about leaks at the edges and silicone coming away from the tiles.
Every job is backed for twelve months, and the guarantee is the same wherever you live. We return to put right any problem with the work.

What we can’t put right
We would rather lose a job than do one that won’t last, so these are the limits:
- A bath or tray that moves, until its support is fixed
- Loose tiles, which need refixing first
- Very wide gaps that need a trim

Work for landlords and builders
Hospitality businesses need rooms back in use quickly, so most of our work is done in a single visit. We’ll fit around changeovers where we can.
Housing associations and facilities teams use us for planned and reactive repairs in Newport and across the UK. Repairing in place avoids the disruption of a replacement, which matters when someone is living in the home.
Repairs by material
Shower trays
We put weight on a tray before sealing it, so the joint is at its widest.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Why it’s worth resealing in Garth
Resealing is a small job. Leaving split or mouldy sealant can let water reach the walls and floor, and that damage costs much more to fix. No two jobs are quite the same, so we price each one individually. What’s damaged, how badly and how easy it is to reach all play a part, and doing several things on one visit costs less than separate visits.

- We cut out all of the old sealant.
- Residue is removed and the joint cleaned.
- Any mould is treated and the joint dried.
- The bath is filled with water, or weight put on the tray.
- New mould-resistant silicone is applied and tooled neatly.
How to prepare
- Let us know which floor the room is on
- Tell us about any previous repairs or coatings
- Clear toiletries, mats and anything else from around the area
How to get a price
Pricing is simple: snap the damage close up and then the entire item, send them to us with your postcode, and we will reply with a fixed price. Quotes are free and you are under no obligation.
Advice
What bath resealing costs
We do not charge extra for travel to Garth. The price comes down to:
- Previous DIY repairs that have to come out
- What the surface is made of
- Whether it’s a chip, crack, burn or wear
- How much damage there is
Most people are surprised how affordable a repair is, particularly next to the cost of replacement. Send photos and we’ll give you the exact figure.
Quotes from your pictures
You can typically get a fixed quote without us visiting. To help us price it:
- Daylight if possible, and no flash reflection
- A picture taken from further back
- One sharp close-up of the damage
- Whether it’s been repaired or coated before
If you’re in Garth and want a price, the easiest route is photos: a close-up, a wider shot and your postcode. You’ll get a fixed quote with dates to choose from.
Looking after it afterwards
To keep it looking its best for years:
- Air the room after use
- Run the extractor fan during and after showers
- Dry the seal after bathing
- Keep bottles off the joints
Leave the sealant to cure for the time we give you, normally around 24 hours.
Do not wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.

Garth questions
Do I need to be at home?
Yes. We need access to the room while we work, at a time that suits you.
Can tenants book a repair?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Are you a vetted contractor?
We hold CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile accreditations.
Will it make a mess?
No. The work area is masked and covered, and we take our waste away with us.
Is it worth repairing rather than replacing?
Normally, if the item is otherwise sound. A repair avoids removal and making good. If replacing would be better, we’ll say so.
How soon can you come?
That depends on our diary for your area. Send photos with your postcode and we will reply with the earliest dates.
Which areas do you work in?
The entire UK, including all of Newport. Just include your postcode and we will offer you dates.
Can you quote from photos?
In nearly every case. We only ask to see it in person if the photos cannot show what we need.
When to call us in Garth
Sealant doesn’t last forever. Every bath or shower adds moisture and soap residue, which mould feeds on, and the joint flexes each time the bath fills.
These are the problems we are asked about most:
- Discoloured, yellow sealant
- Missing sealant behind the taps
- Silicone coming away from the tiles
- Black spots in the silicone
Questions to ask before you book
- How long the guarantee is and what it covers
- If travel is included in the price
- How the room is protected while they work
- What happens if the damage is worse than the photos show
