What affects the price in Heneglwys
We price every job individually, from your photos. What matters most is:
- Whether we combine several jobs
- The size and number of damaged areas
- The material and finish
- What kind of damage it is
We don’t add extras on the day. The price we quote from your photos is the price you pay, and if the damage turns out to be different, we discuss it before starting.
How to get a fixed quote
It only takes a minute to photograph the damage, and it saves a visit. Please include:
- A coin beside the damage so we can judge size
- One picture of the entire bath or shower
- What it’s made of, if you know
- Any earlier repairs or coatings
Call 0345 017 0787 or use the quote form. With a clear picture of the damage and one of the whole bath or shower, we can price the job.
Bath resealing in Heneglwys without replacing anything
All of the old sealant is cut out, treat any mould, and apply fresh mould-resistant silicone. We reseal baths, showers, sinks and worktops, and that includes the awkward spots behind the taps. Whether it’s stained silicone and silicone smeared on tiles, we can help, whatever the material.

Do you need bath resealing in Heneglwys?
Sealant splits when the bath or tray moves, often because it was sealed while the bath was empty.
People generally call us after spotting one of these:
- Mould you cannot clean out
- A messy previous reseal
- Leaks at the edges
- Sealant that’s split or lifting
What to look for in a quote
- A fixed price, and whether VAT is included
- How long the guarantee is and what it covers
- Whether cleaning and preparation are in the price
- Who will actually do the work
Honest limits
A repair isn’t always the answer, and we’ll tell you before we start. We can’t fix:
- Movement in the bath or tray
- Gaps so wide they need filling or trims before sealing
- Water damage behind the bath that needs a builder
Send us pictures and we will tell you honestly.
Materials we repair
- Basins & vanity units
- Shower trays & enclosures
- Baths
- Kitchen worktops & sinks
- Wet rooms
DIY kit or professional repair?
If you’ve already tried a DIY fix, that is fine. We take the old repair out and do it properly, so it does not stop a professional repair. Just mention it when you send photos, as it can add time.
It’s natural to want to try a repair yourself. The trouble is that kit repairs frequently look fine at first and then fail, and the old filler has to come out before a proper repair.
Materials and what they mean for the repair
Shower trays
Trays are sealed with weight on them, for the same reason.
Baths
We fill the bath before sealing, to open the joint fully.
What we do, step by step
You don’t need to empty the room. We bring everything we need with us, lay protective sheets and start once you’re happy with the plan. Most jobs take a couple of hours, and you are welcome to carry on with your day while we work.
- We cut out and remove all of the old sealant.
- Next we clean the joint and deal with mould.
- We ensure the joint is completely dry.
- For a bath, we fill it with water first so the joint is at its widest.
- We apply new mould-resistant silicone and tool it to a neat finish, taps included.
Preparing for the visit
- Let the surface dry out before the visit
- Clear the area around the damage
- Let us know about parking or access
Ask for a price
You don’t need a survey visit. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we’ll reply with a fixed quote.

Common questions in Heneglwys
Is it worth repairing rather than replacing?
In most cases, yes. Replacement brings removal, refitting and making good, which a repair avoids. We’ll be honest if it’s not worth it.
Does someone need to be in?
Yes. We need access to the room while we work, at a time we agree with you.
What do you need from me?
Some photos, your postcode and how to reach you. On the day, access to the room.

Is it safe with children and pets around?

Why does my sealant keep going mouldy?
Damp is the cause. Ventilation and drying keep it clean longer.
