Bath resealing at your home in Derry Downs
Preparation is everything in a reseal: old silicone removed, mould treated, the joint cleaned and dried. Only then does the new sealant go on, as one neat, continuous bead. If you’re dealing with an untidy old seal and discoloured, yellow sealant, we can usually put it right.
You get a one-year guarantee, the same in Derry Downs as everywhere else we work.

What else we do in Derry Downs
How it works
It’s a tidy, low-fuss visit. We confirm the time with you beforehand, cover and mask the work area, and get on with the job, which normally takes a couple of hours. If anything looks different from your pictures, we’ll talk to you before going ahead.
- 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.
Preparing for the visit
- Clear toiletries, mats and anything else from around the area
- Tell us if there are stairs or a lift
- Plan for the room to be out of bounds to pets and children

Should I try a DIY kit first?
What a professional repair adds is preparation, colour matching and finishing. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, then guarantee it for a year.
A kit can be fine for a tiny mark out of sight. For damage in plain view, cracks, holes or rust, or coloured finishes, it’s worth having it done properly.
Questions from Derry Downs
Is repairing better than replacing?
Normally, if the item is otherwise sound. A repair avoids removal and making good. If replacing would be better, we will say so.
How do I stop mould in sealant?
Mostly moisture and poor ventilation. We use mould-resistant silicone, and ventilation helps it last.
Will the price change on the day?
We stop, show you and agree any change before carrying on. You will not be charged for anything you haven’t agreed.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Is there a guarantee?
Yes: twelve months. If anything goes wrong with the repair within the year, we return to fix it.
Can you do more than one item on the same visit?
Yes, and it’s often cheaper. Send pictures of everything together and we’ll quote them together.
Can new silicone go over old?
All the old sealant comes out. New silicone will not bond to old.
Will you leave a mess?
We protect the room with dust sheets and masking first, and tidy up before we leave.
Aftercare tips
It’s all simple stuff, just a few sensible habits:
- Use the extractor fan
- Clean the sealant gently and regularly
- Replace the seal when mould sets in
- Open a window after bathing
Keep the room well ventilated, and dry the joints after bathing.
Reseal before water gets in. Split or lifting sealant is a sign it’s time.
For landlords and businesses
For anyone letting property in or around Derry Downs, we will quote for several properties at once. Send photos for each one and we’ll price them together.
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.
Is resealing worth it?
Compared with repairing water damage, resealing is cheap. It’s a quick job that protects your walls and floors. Every job is a little different, so each one is priced on its own. What’s damaged, how badly and how easy it is to reach all make a difference, and doing several things on one visit costs less than separate visits.

Do you need bath resealing in Derry Downs?
Black mould is the most common reason people reseal. It grows into the silicone, so cleaning only removes the surface.
Send us a photo if you notice any of these:
- Silicone coming away from the tiles
- Water getting behind the bath or tray
- Discoloured, yellow sealant
- Black spots in the silicone

When a repair isn’t the answer
A repair isn’t always the answer, and we would rather say so up front. Repairs won’t solve:
- Tiles that move, until they’re refixed
- Water damage behind the bath that needs a builder
- Movement in the bath or tray
If in doubt, send photos and we’ll say what we think before you book.
