Bath Resealing in Cannon Hill
Bath resealing across Cannon Hill and nearby, usually in one visit and guaranteed for a year.
- Black mould in the sealant
- Silicone smeared on tiles
- Leaks at the edges
DIY repairs versus a professional job
If you’ve already tried a DIY fix, that’s fine. We remove the old filler and start again, so it does not stop a professional repair. Just mention it when you send photos, as it can add time.
If you do try a kit, read the instructions carefully, and do not use it until it has fully cured. If it fails, we can still put it right.
Bath resealing at your home in Cannon Hill
Resealing is quick, but it transforms the look. Fresh joints make the whole room look cleaner, and they keep water out. If you are dealing with silicone coming away from the tiles and missing sealant behind the taps, we can help, whatever the material.
Peace of mind is built in: each job carries a one-year guarantee, and we explain what it covers before you book.

The process
The work is clean and fairly quiet, so you can carry on at home. Protection goes down first, then the job itself takes a couple of hours. At the end we talk you through the curing time and the aftercare.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- 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.
Getting ready for the visit
- Keep children and pets away from the room on the day

Is resealing worth it?
Sealing over old silicone is a false economy. It soon peels, and mould stays trapped behind it. A proper reseal removes the old first. There are no surprise 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.

Prices and what affects them
Every quote is fixed and free. What we look at:
- Previous DIY repairs that have to come out
- How much damage there is
- Unusual colours or finishes
- Access to the area
No two jobs are quite the same, so each one is priced on its own. What’s damaged, how badly and how easy it is to reach all play a part, and doing several things on one visit costs less than separate visits.
How to get a fixed quote
Phone photos are fine. Ensure they show:
- Details of any past repairs
- Any details about the material
- A picture taken from further back
- The postcode, so we can plan the visit
To get a price, send a couple of pictures using our quote form or ring us. We’ll tell you honestly whether it can be repaired.
What we’re called out for in Cannon Hill
Sealant doesn’t last forever. Each shower leaves moisture and soap behind, which mould feeds on, and the joint moves slightly every time the bath is filled.
Send us a picture if you notice any of these:
- Leaks at the edges
- Silicone coming away from the tiles
- Black spots in the silicone
- An untidy old seal
Comparing quotes
- A fixed quote, and whether VAT is included

Common questions in Cannon Hill
Can you price it without visiting?
In nearly every case. If photos do not show enough, we’ll ask for another angle.
Why does my sealant keep splitting?
The bath or tray is probably flexing. If it keeps happening, the support may need fixing.
Can I add another job to the visit?
Yes. Doing several items on one visit usually costs less than separate visits. Include pictures of each item.
Is it messy?
No. The work area is masked and covered, and we take our waste away with us.
Do you do work for letting agents?
Yes. We work for landlords, agents, builders and businesses as well as householders in Cannon Hill.
How long does a reseal take?
Most reseals take about two hours. Leave it to cure before use.
Why does my sealant keep going mouldy?
Damp is the cause. Ventilation and drying keep it clean longer.
How long does silicone take to cure?
You’ll get the curing time from us, usually around a day.
When a repair is not the answer
It helps to know what we cannot do too:
- Movement in the bath or tray
- Very wide gaps that need a trim
- Loose tiles, which need refixing first
Not sure? Send photos and we will give you a straight answer before you book.
Surfaces we repair
- Shower trays & enclosures
- Kitchen worktops & sinks
- Baths
- Wet rooms
- Basins & vanity units
What your bath or shower is made of matters
Baths
We fill the bath before sealing, so the joint is at its widest.
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.
Looking after it afterwards
Nothing complicated is needed, just a few sensible habits:
- Reseal when black spots won’t clean off
- Give the seal a regular clean
- Air the room after use
- Use the extractor fan
Avoid scraping the joints, and don’t stand bottles on the seal.
Damp below or loose tiles need checking quickly. It may be more than a reseal, and we will say if you need a builder or plumber.
