Colnbrook questions
It’s been repaired before. Can you still fix it?
In most cases. The old repair comes out first.
Is it OK to have pets in the house?
Yes, as long as they stay out of the room we’re working in. We will let you know when it’s safe to use again.
How long does silicone take to cure?
Normally about a day later. We confirm before we leave.
What happens if you find more damage?
It’s rare, but if it happens we talk to you first. The price only changes if you agree.
Do you come to Colnbrook?
We do. We send a technician to Colnbrook for every job, with no extra charge for travel.
Is a repair better than a new one?
Generally, yes. Replacement brings removal, refitting and making good, which a repair avoids. We will be honest if it’s not worth it.
Do the materials smell?
Some materials have a smell while they’re applied, which is why we ventilate. It fades as everything cures.
How much does bath resealing cost in Colnbrook?
The exact price depends on the damage, so we quote from pictures. You know the full cost before anything is booked.
Bath resealing in Colnbrook without replacing anything
A proper reseal starts with removing every trace of the old silicone. Fresh sealant doesn’t stick to old, which is why many DIY jobs peel. Typical jobs include missing sealant behind the taps and gaps in the seal, in basins & vanity units, wet rooms and kitchen worktops & sinks.
A one-year guarantee comes as standard, so you are not left on your own once we have gone.

How to look after the repair
Good habits make a big difference to how long a repair lasts:
- Ventilate the bathroom well
- Don’t stand toiletries on the seal
- Clean the joints with a mild cleaner
- Dry the seal after bathing
Run the extractor fan, wipe the joints dry after use, and clean them regularly with a mild cleaner to slow mould growth.
Mouldy sealant is more than a cosmetic problem; it shows moisture is getting in. Resealing early keeps water out of the walls and floor.
How it works
On the day, we arrive at the time we’ve agreed, cover the area with dust sheets and masking, and set to work. Expect it to take around two hours. We clean up when we are done and tell you when it’s ready to use.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- Any mould is treated and the joint dried.
- The bath is filled with water, or weight put on the tray.
- We apply fresh mould-resistant silicone and tool a neat bead.
Preparing for the visit
- Tell us about any previous repairs or coatings
- Keep a parking space free if you can
- Keep children and pets away from the room on the day

What your bath or shower is made of matters
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.
Can I fix it myself?
DIY kits are sold for most surfaces, and they can make a small mark look better. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.
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.
Why it’s worth resealing in Colnbrook
A reseal is one of the cheapest bathroom jobs there is, and it protects everything around the bath. Leaving failed sealant can let water cause damage that costs far more to fix. We don’t add extras on the day. The price we quote from your photos is the price you pay, and if the damage turns out to be different, we discuss it before starting.
