Bath resealing in Pant-mawr without replacing anything
A reseal is a small job that makes a big difference. Clean, white joints make a bathroom look cared for, and they keep water out. If you are dealing with silicone smeared on tiles and silicone coming away from the tiles, we can normally put it right, whatever the material.
You’re covered after we leave: our one-year guarantee applies to every job, and we explain what it covers before booking.

Signs you need bath resealing in Pant-mawr
Black mould is the most common reason people reseal. It grows into the silicone, so cleaning cannot get it all out.
Signs it’s time to call us include:
- Gaps in the seal
- Leaks at the edges
- Old sealant that looks dirty
- Gaps by the taps
Questions to ask before you book
- How your room will be protected
- How the colour is matched
- If travel is included in the price
- Who will actually do the work
What we cannot put right
Honesty matters more than a booking, so here’s what a repair will not do:
- Water damage behind the bath that needs a builder
- Movement in the bath or tray
- Tiles that move, until they’re refixed
If in doubt, send photos and we’ll say what we think.

The process
From the moment we arrive, the aim is to do the job without disturbing the rest of your home. Surfaces nearby are masked off, the job takes around two hours, depending on what we find, and we finish with a tidy-up and a look at the finished work together.
- The surrounding area is protected and the joints masked.
- Old sealant and residue are removed.
- The joint is cleaned, treated and dried.
- 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
- Open a window if you can
- Plan for the room to be out of bounds to pets and children
- Clear the area around the damage

Landlords, agents and businesses in Pant-mawr
Builders, developers and site managers book us for snagging repairs, putting right damage done during fitting so nothing needs replacing. We’re CHAS, Constructionline and SafeContractor accredited.
We carry out planned and one-off repairs for housing associations and facilities teams in Cardiff and across the UK. Repairing in place avoids the disruption of a replacement, which matters when someone is living in the home.
Can I fix it myself?
For a hairline mark somewhere you’ll never see, a kit may be enough. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, it’s worth having it done properly.
It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is usually cheaper.

Keeping it looking good
Nothing complicated is needed, just a few sensible habits:
- Reseal at the first sign of lifting
- Store bottles on a shelf
- Air the room after use
- Use the extractor fan
Avoid scraping the joints, and keep shampoo bottles off the joints.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. It may be more than a reseal, and we’ll say if you need a builder or plumber.
What bath resealing costs
There are no hourly rates or hidden extras. The price is based on:
- The material
- Whether old repairs or coatings need taking off
- What kind of damage it is
- Whether we combine several jobs
Set against the cost of replacement, a repair is normally a fraction of the price, because there’s no removal, plumbing or making good. The quote lists exactly what you are paying for.
Getting a price from pictures
The better the pictures, the more accurate the price. Here’s what helps:
- Any details about the material
- Details of any past repairs
- A clear, close picture of the problem area
- Something in shot to show the size
No survey visit is needed: we price from pictures. Send them through the quote form, or call 0345 017 0787 if you’d rather talk it through, and you’ll get a fixed figure back.
Is resealing worth it?
A reseal is one of the cheapest bathroom jobs there is. Leaving failed sealant can let water cause damage that costs far more to fix. A repair normally costs much less than people expect, especially compared with replacing and refitting. Send pictures and we will give you the exact figure.

Pant-mawr questions
What happens after I send pictures?
You get a fixed price and available dates. If anything’s unclear, we’ll ask for another photo.
Is it safe with children and pets around?
Yes, as long as they stay out of the room we’re working in. We will tell you when the room can be used again.
Is my repair covered?
Every repair comes with a one-year guarantee. Ask us what it covers when you get your quote.
Will there be a smell?
A little, depending on the job. Open windows and an extractor fan help, and it soon fades.
Can you repair something that is been repaired before?
In most cases. We remove the old repair before doing a new one, so mention it when you send photos.
Why does my sealant keep going mouldy?
Mostly moisture and poor ventilation. Mould-resistant silicone and good ventilation help.
Do you seal over the old sealant?
No, we never seal over old silicone. It’s removed, cleaned off and the joint dried first.
Can you quote from pictures?
Nearly always. We only ask to see it in person if the pictures can’t show what we need.
