Bath & shower resealing (mastic) in Cold Harbour, Windsor and Maidenhead
Bath, shower and sink resealing with new mould-resistant silicone in Cold Harbour, carried out at your home and guaranteed for a year.
- Missing sealant behind the taps
- Black spots in the silicone
- Water getting behind the bath or tray
Can I fix it myself?
If you’ve already tried a DIY fix, that is fine. We remove the old filler and start again, so it does not stop a professional repair. Just mention it when you send pictures, as it can add time.
It’s natural to want to try a repair yourself. The risk is that a kit repair hides the damage for a while, then fails, and the old filler has to come out before a proper repair.
Bath resealing at your home in Cold Harbour
We cut out all of the old sealant, treat any mould, and reseal with new mould-resistant silicone. We do this for baths, showers, sinks and worktops, including the awkward bits behind the taps. If you are dealing with silicone smeared on tiles and leaks at the edges, we can help.
The work is covered for a year after we finish. If anything is not right, ring us and we’ll sort it.

Landlords, agents and businesses in Cold Harbour
Builders use us to fix snagging damage before handover, saving last-minute replacements. Several plots can be done in one visit to keep costs down.
Hotels, guest houses and holiday lets cannot afford rooms out of action for long, so we keep visits short and tidy. We’ll fit around changeovers where we can.
What bath resealing costs
You’ll know the full cost before booking. We look at:
- The material
- Whether it’s a chip, crack, burn or wear
- Whether we combine several jobs
- Whether old repairs or coatings need taking off
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 photos and you’ll get a fixed figure.
Quotes from your pictures
You can take the pictures on your phone, there is no need for anything special. Make sure they show:
- Where you are, by postcode
- Any earlier repairs or coatings
- A close-up of the damage, in focus
- A picture taken from further back
Email us a picture of the damage and one of the whole item, with your SL6 postcode, and we’ll come back with a fixed quote.
How to care for the repair
So the finish stays in good condition for years:
- Keep bottles off the joints
- Use the extractor fan
- Keep the joints dry
- Open a window after bathing
Do not scrape the sealant with anything sharp, and do not stand bottles on the seal.
Black mould in sealant is not just unsightly; it shows moisture is getting in. Resealing early keeps water out of the walls and floor.
What a repair can’t fix
It helps to know what we cannot do:
- Very wide gaps that need a trim
- A bath or tray that moves, until its support is fixed
- Loose tiles, which need refixing first
Send us pictures and we’ll tell you honestly.
What we work on
- Kitchen worktops & sinks
- Wet rooms
- Shower trays & enclosures
- Basins & vanity units
- Baths
FAQs for Cold Harbour
My seal keeps tearing. Why?
Usually because the bath or tray moves, or it was sealed with the bath empty. We fill the bath before sealing it.
Do I have to be there?
We need someone to let us in. After that, you can carry on with your day.
Can you repair several things at once?
Of course, and it normally saves money. Send pictures of everything together and we will quote them together.
Is there a guarantee?
Every repair comes with our one-year guarantee. Ask us what it covers when you get your quote.
How do I book?
Photos of the damage, a picture of the whole bath or shower and your postcode. After that, we just agree a date.
Is it safe with children and pets around?
Yes, as long as they stay out of the room we’re working in. We’ll tell you when the room can be used again.
How do I stop mould in sealant?
Generally poor ventilation and moisture sitting on the joint. We use mould-resistant silicone, and ventilation helps it last.
Is it worth repairing rather than replacing?
Usually, if the item is otherwise sound. A repair avoids removal and making good. We will tell you honestly if replacement makes more sense.

Is resealing worth it?
