Why it’s worth resealing in Blackwood
A reseal is one of the cheapest bathroom jobs there is, and it protects everything around the bath. Leaving failed sealant can let water cause damage that costs far more to fix. 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.

Bath resealing at your home in Blackwood
We cut out all of the old sealant, treat any mould, and apply fresh mould-resistant silicone. We do this for baths, showers, sinks and worktops, and that includes the awkward spots behind the taps. We work on wet rooms, baths and shower trays & enclosures, and the jobs we see most are black mould in the sealant and discoloured, yellow sealant.
The work is covered for a year after we finish. Just call us if there’s a problem and we will come back.

FAQs for Blackwood
Can pets and children be at home?
Keep pets and children away from the work area on the day, mainly so nothing gets touched before it has cured.
Why does the silicone keep cracking?
Typically because the bath or tray moves, or it was sealed with the bath empty. We fill the bath before sealing it.
How do I stop mould in sealant?
Typically poor ventilation and moisture sitting on the joint. We use mould-resistant silicone, and ventilation helps it last.
Do you work for landlords and businesses?
We do, regularly. We can quote for several properties together and work between tenancies.
What happens next?
We check the damage, the material and your postcode, then reply with a quote.
Do you charge for travel?
There is no separate call-out charge. Your fixed quote includes everything.
Can you price it without visiting?
Nearly always. If photos don’t show enough, we’ll ask for another angle.
Can you redo someone else’s repair?
Yes, we frequently do. It can add a little time, which we include in the quote.
When a repair isn’t the answer
A repair isn’t right for every job, including:
- Movement in the bath or tray
- Gaps too big for silicone alone
- Hollow or loose tiles
Not sure? Send photos and we will give you a straight answer.

What we do, step by step
Here’s how a visit generally runs: we arrive on time, sheet and mask the area around the job, carry out the work and tidy away. Plan for around two hours from start to finish. Before leaving, we tell you when it can be used and what to avoid for the first few days.
- We cut out all of the old sealant.
- Residue is removed and the joint cleaned.
- Any mould is treated and the joint dried.
- We fill the bath, or weight the tray, to open the joint.
- New mould-resistant silicone is applied and tooled neatly.
Preparing for the visit
- Let the surface dry out before the visit
- Keep pets and children out of the room while we work
- Keep a parking space free if you can

What bath resealing costs
You won’t pay by the hour. The price is based on:
- How easy the damage is to reach
- Whether we combine several jobs
- The colour and finish to match
- Previous DIY repairs that have to come out
We charge the same wherever you are, so there is no premium for Blackwood. What changes the price is the job itself: the material, the amount of damage and how many items.
How to get a fixed quote
Most quotes are done from photos alone. To help us price it:
- One picture of the entire bath or shower
- Any details about the material
- A coin or ruler next to the damage for scale
- A close-up of the damage, in focus
There’s no need for us to visit first. Nearly every job can be priced from pictures: send a close-up, a wider shot and your postcode, and we’ll reply with a fixed quote.
DIY repairs versus a professional job
A DIY attempt isn’t a disaster. We remove the old filler and start again, so it will not stop us repairing it. Just mention it when you send photos, as it can add time.
If you’re set on a kit, follow its instructions closely, make sure the area is clean and completely dry, and give it the full curing time. If it doesn’t work out, we can still repair it properly.
Signs you need bath resealing in Blackwood

Common reasons people in Blackwood contact us are:
- Gaps in the seal
- An untidy old seal
- Black mould in the sealant
- Water getting behind the bath or tray
Questions to ask before you book
- Aftercare advice
- How long it needs to cure
- Whether cleaning and preparation are in the price
- What happens if the damage is worse than the pictures show
