Bath resealing at your home in South Hylton
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. Typical jobs include missing sealant behind the taps and stained silicone, across baths, shower trays & enclosures and wet rooms.
A one-year guarantee comes as standard, so you’re not left on your own once we have gone.

What we cannot put right
Not everything can be repaired, and we would rather say so up front. We cannot fix:
- Tiles that move, until they’re refixed
- Gaps too big for silicone alone
- Hidden water damage
If in doubt, send photos and we’ll say what we think.
What we work on
- Wet rooms
- Kitchen worktops & sinks
- Basins & vanity units
- Baths
- Shower trays & enclosures
Why reseal now?
Resealing is a small job. Putting off a reseal lets water get behind the bath or tray, and that damage costs much more to fix. Every job is a little different, so we price each one individually. The size and type of damage, the material and access all make a difference, and combining jobs on one visit brings the cost down.

What else we do in South Hylton
Landlords, agents and businesses in South Hylton
Rental properties take more wear, and replacing items every time a tenant leaves is expensive. Repairing between tenants keeps the property presentable for less.
For developers and builders, we fix damage before handover, so there is no need to replace a damaged item at the last minute. We can visit several plots in one trip to keep costs down.
What your bath or shower is made of matters
Shower trays
We put weight on a tray before sealing it, for the same reason.
Baths
We fill the bath before sealing, to open the joint fully.
Questions from South Hylton
Why does mould come back so fast?
Mostly moisture and poor ventilation. We use mould-resistant silicone, and ventilation helps it last.
How do I get a price for bath resealing in South Hylton?
Because every job differs, we price from pictures. You will get a fixed figure before you book.
Do you seal over the old sealant?
No, we never seal over old silicone. It’s removed, cleaned off and the joint dried first.
Is my repair covered?
All our work carries a one-year guarantee. Ask us what it covers when you get your quote.
Why does my sealant keep splitting?
Movement is the usual cause. We fill the bath before sealing it.
When can I use the bath after resealing?
Normally about a day later. We will tell you the exact time.
Can you repair several things at once?
Yes. Combining jobs on one visit brings the cost down. Send photos of everything you’d like done.
How long does a reseal take?
Usually a couple of hours, then it needs to cure.
When to call us in South Hylton
Sealant doesn’t last forever. Each shower leaves moisture and soap behind, which mould feeds on, and the joint moves slightly every time the bath is filled.
The things customers generally mention when they call include:
- Black mould in the sealant
- Stained silicone
- Damp near the bath
- A messy previous reseal
Comparing quotes

- What happens if they find more damage
- How long it needs to cure
- Is the price fixed, and does it include VAT?
DIY kit or professional repair?
We understand the appeal of fixing it yourself. The risk is that a kit repair hides the damage for a while, then fails, and then the old filler has to be removed first.
It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Doing it properly first is generally the cheaper route.
Looking after it afterwards
So the finish stays in good condition for years:
- Reseal at the first sign of lifting
- Give the seal a regular clean
- Keep bottles off the joints
- Keep the joints dry
Leave the sealant to cure for the time we give you, normally about a day.
Black mould in sealant is not just unsightly, it’s a sign moisture is sitting in the joint. An early reseal keeps water where it belongs.
