Bath resealing at your home in Holwell
A good reseal is all about preparation: every bit of old silicone out, mould treated, the joint clean and dry. Then the fresh sealant goes on, in a neat, continuous bead. Common call-outs are for silicone coming away from the tiles and black spots in the silicone, in wet rooms, baths and kitchen worktops & sinks.
We guarantee the work for a year. If something isn’t right in that time, we come back and put it right.

Different materials, different repairs
Shower trays
We put weight on a tray before sealing it, so the joint is at its widest.
Sinks and worktops
Basins, vanity units and kitchen worktops are resealed too, once the joint is completely dry.
Aftercare tips
Most damage we see is avoidable. A few tips:
- Use the extractor fan
- Wipe the joints dry after use
- Store bottles on a shelf
- Clean the sealant gently and regularly
Avoid scraping the joints, and keep shampoo bottles off the joints.
If you notice damp, stains on the ceiling below or loose tiles, act quickly. It may be more than a reseal, and we will say if you need a builder or plumber.

Holwell questions
Can you reseal over the old silicone?
We always remove the old sealant completely. New silicone won’t bond to old.
Do you do work for letting agents?
Yes. We carry out repairs for householders, landlords, letting agents, builders and businesses.
Can you repair something that is been repaired before?
Generally, yes. Tell us what was done before and we’ll plan for it.
Can tenants book a repair?
Yes, though it’s best to check with your landlord first. Landlords are often glad to have it sorted.
What happens once I’ve sent photos?
We review the pictures and send a fixed quote.
Will the price change on the day?
It’s rare, but if it happens we talk to you first. You decide whether to go ahead.
What areas do you cover?
Across the UK, and that includes Holwell. Prices do not change with location.
Is there a guarantee?
Yes: twelve months. If anything goes wrong with the repair within the year, we return to fix it.
How we price bath resealing
We price every job individually. What matters most is:
- Doing more than one item at once
- How much damage there is
- Previous DIY repairs that have to come out
- What kind of damage it is
Every job is a little different, so we price each one individually. 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.
How to get a fixed price
Before you send photos, a few simple things make all the difference:
- Daylight if possible, and no flash reflection
- A clear, close picture of the problem area
- A picture taken from further back
- What it’s made of, if you know
Send us a picture of the damage and a wider shot of the entire item, with your SG5 postcode, and we will come back with a fixed quote.

Is resealing worth it?
Sealing over old silicone is a false economy. It peels within weeks, and traps mould underneath. A proper reseal removes the old first. There are no surprise extras on the day. What we quote from your pictures is what you pay, unless the damage turns out to be different, in which case we talk to you first.

DIY repairs versus a professional job
A kit can be fine for a tiny mark out of sight. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, it’s worth having it done properly.
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, then guarantee it for a year.
When to call us in Holwell
Sealant splits when the bath or tray moves, frequently because it was sealed with the bath empty.
If you can see any of these, send us a photo:
- Silicone smeared on tiles
- Unsealed corners
- Black mould in the sealant
- Stained silicone
Before booking anyone

- What happens if they find more damage
- What protection goes down before work starts
