How we handle bath resealing in Blackwood
We reseal baths, shower trays, basins and worktops, with mould-resistant sanitary silicone. Most jobs take a couple of hours, plus curing time. We regularly repair kitchen worktops & sinks, baths and shower trays & enclosures, and the jobs we see most are a messy previous reseal and gaps in the seal.
We stand behind the work with a one-year guarantee, so you are not left on your own once we have gone.

Different materials, different repairs
Shower trays
Trays are sealed with weight on them, for the same reason.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, once the joint is completely dry.
Why reseal now?
A professional reseal costs little compared with water damage. It’s quick, tidy and protects your home. Set against the cost of replacement, repairing typically costs far less, because nothing has to be taken out, refitted or made good. Your fixed quote shows exactly what’s included.

Blackwood: your questions answered
Which areas do you work in?
The whole UK, including all of South Lanarkshire. Send your postcode with your photos and we’ll offer you dates.
Why does my sealant keep going mouldy?
Damp is the cause. Run the fan, dry the joints and the new seal stays cleaner for longer.
When can you do it?
Your quote comes with available dates. If it’s urgent, say so and we’ll do what we can.
What information do you need?
Use the quote form or ring 0345 017 0787, and we’ll do the rest.
Do you seal over the old sealant?
We always remove the old sealant completely. New silicone will not bond to old.
Do you hold any accreditations?
We are accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.
Can you repair something that’s been repaired before?
Normally, yes. The old repair comes out first, so let us know about it.
What happens after I send pictures?
You get a fixed quote and available dates. If anything’s unclear, we’ll ask for another photo.

What else we do in Blackwood
Do you need bath resealing in Blackwood?
No sealant lasts for ever. Every bath or shower adds moisture and soap residue, which mould loves, and the joint moves slightly every time the bath is filled.
You may need us if you’ve spotted:
- Gaps in the seal
- Missing sealant behind the taps
- A messy previous reseal
- Damp near the bath
What your quote should include
- What protection goes down before work starts
- Is the price fixed, and does it include VAT?
- Aftercare advice
- What happens if the damage is worse than the photos show
DIY repairs versus a professional job
If you’ve already tried a DIY fix, that’s fine. We take the old repair out and do it properly, so it won’t stop us repairing it. It does add a little time, so tell us about it when you send pictures.
It’s natural to want to try a repair yourself. The risk is that a kit repair hides the damage for a while, then fails, and the old filler has to come out before a proper repair.
Keeping it looking good
Much of the damage we repair could have been avoided. These habits help:
- Let steam out after showers
- Use the extractor fan
- Reseal when black spots won’t clean off
- Dry the seal after bathing
Use the extractor fan, dry the joints after bathing, and clean them regularly with a mild cleaner to slow mould growth.
Black mould in sealant isn’t just unsightly, it’s a sign moisture is sitting in the joint. An early reseal keeps water where it belongs.
