How we handle bath resealing in Trecastle
Resealing is one of the simplest ways to protect your bathroom. Failed sealant lets water get where it shouldn’t, and a new seal stops it. If you’re dealing with mould you can’t clean out and sealant that’s split or lifting, we can help.
You are covered for a year from the day of the repair. Just call us if there’s a problem and we will come back.

Why reseal now?
Resealing is a small job. Putting off a reseal can let water reach the walls and floor, and that damage costs much more to fix. It helps to know what pushes a price up or down: access, material, the extent of the damage and whether we can do several items together. Send pictures and you’ll get a fixed figure.

Should I try a DIY kit first?
What a professional repair adds is preparation, colour matching and finishing. We prepare the area properly, mix the colour on site and polish the finish to match, and the work is guaranteed.
For a hairline mark somewhere you’ll never see, a kit may be enough. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, a professional repair is worth it.
Trecastle: your questions answered
Are you accredited?
Yes. Our accreditations include CHAS, Constructionline and SafeContractor. See our accreditations page for the full list.
Is repairing better than replacing?
In most cases, yes. A repair skips the removal, fitting and redecorating. We’ll be honest if it’s not worth it.
How quickly can you book me in?
It depends on the time of year and where you are. Send pictures with your postcode and we will reply with the earliest dates.
What happens next?
You’ll get a fixed quote back, generally with dates to choose from. You’re under no obligation.
Why does my sealant keep going mouldy?
Mostly moisture and poor ventilation. We use mould-resistant silicone, and ventilation helps it last.
How long does a reseal take?
Typically a couple of hours, then it needs to cure.
Can tenants book a repair?
Yes, though it’s best to check with your landlord first. Landlords are often glad to have it sorted.
Do you work for landlords and businesses?
Yes, frequently. We quote for multiple addresses and fit around tenancy changeovers.
For landlords and businesses
We also carry out snagging repairs for builders and developers, putting right damage done during fitting so nothing needs replacing. We are CHAS, Constructionline and SafeContractor accredited.
Hotels, guest houses and holiday lets cannot afford rooms out of action for long, so most of our work is done in a single visit. We will fit around changeovers where we can.

What else we do in Trecastle
How to care for the repair
Simple care helps the repair last. Our advice:
- Clean the sealant gently and regularly
- Keep the joints dry
- Don’t stand toiletries on the seal
- Air the room after use
Let it cure fully before using the bath or shower, normally about a day.
Do not wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.
What we do, step by step
On the day, the technician arrives at the agreed time, protects the room with dust sheets and masking and gets started. Expect it to take about two hours for a bath. We tidy up before we leave and let you know when you can use it again.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- We treat mould and dry the joint thoroughly.
- 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
- Tell us if there are stairs or a lift
- Let the surface dry out before the visit
- Have a window or extractor fan available
How to get a price
Getting a price is easy: take a close-up of the damage and a picture from further back, send them to us with your postcode, and we will reply with a fixed price. Quotes are free and you are under no obligation.

How we price bath resealing
Every quote is fixed and free. What we take into account:
- How easy the damage is to reach
- The colour and finish to match
- Whether it’s a chip, crack, burn or wear
- The material
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.
Send pictures for a quote
Two or three clear pictures are typically enough. It helps if you send:
- Where you are, by postcode
- Good light, ideally daylight, without flash glare
- The material, if you know it
- A clear, close picture of the problem area
No survey visit is needed: we price from photos. Send them through the quote form, or call 0345 017 0787 if you’d rather talk it through, and we’ll come back with a fixed figure.
