Materials and what they mean for the repair
Baths
Baths are resealed with water in them, so the joint is at its widest.
Shower trays
Trays are sealed with weight on them, for the same reason.
The process
Arrival times are agreed in advance, so you know when to expect us. On site, it takes about two hours for a bath. We leave the room clean and you will know when it can be used.
- The old silicone is cut out completely.
- Residue is removed and the joint cleaned.
- 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.
Getting ready for the visit
- Point us to the nearest place to park
- Keep pets and children out of the room while we work
- Let the surface dry out before the visit

Landlords, agents and businesses in Thealby
If you manage property in Thealby, we can repair and quote for several addresses together. Just send photos for each address and we’ll come back with a combined price.
Rented homes see more wear and tear, and replacing items every time a tenant leaves is expensive. A repair between tenancies is a cheaper way to keep the property in good order.

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. Rather than charging by the hour, we price the entire job up front. It depends on the damage, the material and access, and combining items on one visit brings it down.

What we can’t put right
It helps to know what we can’t do:
- Very wide gaps that need a trim
- A bath or tray that moves, until its support is fixed
- Hollow or loose tiles
Send us pictures and we’ll tell you honestly before booking.
What we work on
- Wet rooms
- Baths
- Kitchen worktops & sinks
- Shower trays & enclosures
- Basins & vanity units
DIY repairs versus a professional job
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.
If you do try a kit, read the instructions carefully and work on a clean, dry surface, and do not use it until it has fully cured. If it fails, we can still put it right.
Thealby: your questions answered
Why does mould come back so fast?
Damp is the cause. Ventilation and drying keep it clean longer.
Can I add another job to the visit?
Yes. Doing several items on one visit usually costs less than separate visits. Include pictures of each item.
Will the price change on the day?
We’ll show you and explain before doing anything extra. Nothing extra is done without your say-so.
Are you a vetted contractor?
Yes, including CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.
Is it messy?
Dust sheets and masking go down before we start, and tidy up before we leave.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
How do I get a price for bath resealing in Thealby?
The exact price depends on the damage, so we quote from pictures. You will get a fixed figure before you book.
Can new silicone go over old?
Never over old. It’s removed, cleaned off and the joint dried first.
What affects the price in Thealby
A fixed quote means you know the cost before you book. We look at:
- Whether we combine several jobs
- Previous DIY repairs that have to come out
- Access to the area
- Unusual colours or finishes
The price depends on the type and amount of damage, what it’s made of and how many items we do on one visit. We give a fixed price from your pictures, so you know the cost before booking.
Quotes from your pictures
You can take the photos on your phone, there’s no need for anything special. Ensure they show:
- A photo taken from further back
- Good light, ideally daylight, without flash glare
- A clear, close picture of the problem area
- The postcode, so we can plan the visit
The quickest way to a price is to send two or three pictures through our quote form or call us. We will say immediately whether it can be repaired.
