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, a professional repair is worth it.
It’s tempting to reach for a kit, but the repairs we redo most often are DIY ones that have discoloured or lifted. Getting it right first time is usually cheaper.
Bath resealing at your home in Sandridge
Resealing is quick, but it transforms the look. Clean, white joints make a bathroom look cared for, and they keep water out. We regularly repair wet rooms, kitchen worktops & sinks and basins & vanity units, and common reasons people get in touch are leaks at the edges and missing sealant behind the taps.
We guarantee the work for a year. If something is not right in that time, we come back and put it right.

Aftercare tips
So the finish stays in good condition:
- Wipe the joints dry after use
- Clean the joints with a mild cleaner
- Replace the seal when mould sets in
- Run the extractor fan during and after showers
Use the extractor fan, wipe the joints dry after use, and clean them regularly with a mild cleaner to slow mould growth.
Black mould in sealant is not just unsightly; it shows moisture is getting in. An early reseal keeps water where it belongs.
When to call us in Sandridge
In time, even good sealant discolours particularly in a well-used bathroom. Steam, soap and movement all wear it down.
If you can see any of these, send us a photo:
- Stained silicone
- Black spots in the silicone
- Water getting behind the bath or tray
- Gaps by the taps

Sandridge: your questions answered
Can pets and children be at home?
Just keep them out of the work area. We’ll let you know when it’s safe to use again.
Do you cover the entire of Hertfordshire?
Across the UK. Our prices are the same everywhere.
What does bath resealing cost?
Every job gets a fixed quote based on pictures of the damage. Send a close-up and a picture of the entire item and your postcode.
Why does my sealant keep splitting?
Movement is the usual cause, or it was sealed with the bath empty. We seal baths full of water.
Is a repair better than a new one?
In most cases, yes. Replacement brings removal, refitting and making good, which a repair avoids. If it is not worth repairing, we’ll tell you.
When can I use the bath after resealing?
Generally after around 24 hours. We confirm before we leave.
What if the damage is worse than the photos show?
We stop, show you and agree any change before carrying on. You won’t be charged for anything you haven’t agreed.
Do the materials smell?
It depends on the job, but often a little. Open windows and an extractor fan help, and it soon fades.
Resealing in Sandridge: why it matters
A reseal is one of the cheapest bathroom jobs there is. Leaving failed sealant can let water cause damage that costs far more to fix. It helps to know what pushes a price up or down: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Photos let us give you a fixed figure.

What a repair can’t fix
In fairness, there are a few things a repair will not fix:
- Water damage behind the bath that needs a builder
- Gaps so wide they need filling or trims before sealing
- A bath or tray that moves, until its support is fixed
If in doubt, send pictures and we’ll say what we think before booking.

The process
You do not need to empty the room. We bring everything we need with us, put protection down and start once you are happy with the plan. It normally takes around two hours, and you can get on with other things while we’re there.
- The surrounding area is protected and the joints masked.
- We remove the old sealant and every trace of residue.
- The joint is cleaned, treated and dried.
- Fresh silicone is applied in a continuous bead.
- We smooth the bead, remove the tape and leave it to cure.
Getting ready for the visit
- Mention if the room is upstairs or in a flat
- Keep a parking space free if you can
- Let the surface dry out before the visit
