About our bath resealing in Barmston
Baths, trays, basins and kitchen worktops all get resealed, with mould-resistant sanitary silicone. Most jobs take a couple of hours, then it needs to cure. Our technicians work on baths, wet rooms and kitchen worktops & sinks, and people most frequently call us about an untidy old seal and mould you can’t clean out.

Keeping it looking good
Looking after the surface is easy:
- Keep the joints dry
- Store bottles on a shelf
- Replace the seal when mould sets in
- Air the room after use
Let it cure fully before using the bath or shower, typically around 24 hours.
Mouldy sealant is more than a cosmetic problem, it’s a sign moisture is sitting in the joint. Resealing early keeps water out of the walls and floor.
Repairs by material
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, with the joint fully dried first.
Shower trays
We put weight on a tray before sealing it, for the same reason.

FAQs for Barmston
It’s been repaired before. Can you still fix it?
Typically, yes. The old repair comes out first, so let us know about it.
Do you work for landlords and businesses?
Yes. We carry out repairs for householders, landlords, letting agents, builders and businesses.
Do you charge for travel?
We do not add a call-out fee. The fixed price covers the visit and the work.
How do I stop mould in sealant?
Mostly moisture and poor ventilation. Mould-resistant silicone and good ventilation help.
Which areas do you work in?
Everywhere in the UK, Barmston included. Travel is included in the price.
Is it worth repairing rather than replacing?
Generally, yes. Replacement brings removal, refitting and making good, which a repair avoids. We will be honest if it’s not worth it.
Is it messy?
Very little mess: we sheet and mask everything nearby, and we take our waste away with us.
How soon can you come?
It depends on the time of year and where you are. Send pictures with your postcode and we will reply with the earliest dates.
DIY repairs versus a professional job
For a hairline mark somewhere you’ll never see, a kit may be enough. For damage in plain view, cracks, holes or rust, or coloured finishes, a professional repair is worth it.
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 does not work out, we can still repair it properly.
Why it’s worth resealing in Barmston
Compared with repairing water damage, resealing is cheap. It’s a quick job that protects your walls and floors. The price depends on the type and amount of damage, what it’s made of and how many jobs we combine into one visit. We give a fixed quote from your pictures, so you know the cost before you book.

What affects the price in Barmston
Quotes are free and the price is fixed. What we take into account:
- The size and number of damaged areas
- The type of damage
- Whether old repairs or coatings need taking off
- The material
No two jobs are quite the same, so each one is priced on its own. What’s damaged, how badly and how easy it is to reach all play a part, and doing several things on one visit costs less than separate visits.
Send photos for a quote
When you take your photos, a few simple things make all the difference:
- Details of any past repairs
- One sharp close-up of the damage
- Your postcode, so we can check dates
- One picture of the entire bath or shower
If you are in Barmston and want a price, the easiest route is photos: one close up, one from further back, plus your postcode. We reply with a fixed quote and our next available dates.
What we do, step by step
On the day itself, there’s little for you to do. Show us the job, point us to the room, and we will get on with it. Most visits take about two hours for a bath.
- 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.
- We apply fresh mould-resistant silicone and tool a neat bead.
How to prepare
- Have a window or extractor fan available
- Let us know which floor the room is on
- Clear toiletries, mats and anything else from around the area
Ask for a price
Pricing is simple: snap the damage close up and then the entire item, send them over with your postcode, and we’ll reply with a fixed quote. There is no charge for the quote and no obligation.
