Bath resealing in Coldharbour without replacing anything
A good reseal is all about preparation: old silicone removed, mould treated, the joint cleaned and dried. Then the fresh sealant goes on, as one neat, continuous bead. Typical jobs include black spots in the silicone and old sealant that looks dirty, in wet rooms, basins & vanity units and kitchen worktops & sinks.
You are covered for a year from the day of the repair. Just call us if there is a problem and we will sort it.

For landlords and businesses
Rental properties take more wear, and replacing items every time a tenant leaves is expensive. Repairing between tenants keeps the property presentable for less.
We are used to working with agents and managing companies. Send the address, photos and access details.
What your bath or shower is made of matters
Baths
Baths are resealed with water in them, to open the joint fully.
Shower trays
We put weight on a tray before sealing it, for the same reason.
Do you need bath resealing in Coldharbour?
Poor ventilation speeds things up: damp hangs around, and mould takes hold.
Customers usually contact us about:
- Gaps in the seal
- Damp near the bath
- Unsealed corners
- An untidy old seal
Comparing quotes
- How long the guarantee is and what it covers
- Whether cleaning and preparation are in the price
- What happens if they find more damage
- Is the price fixed, and does it include VAT?
How to care for the repair
Aftercare is simple:
- Ventilate the bathroom well
- Reseal when black spots will not clean off
- Keep bottles off the joints
- Clean the joints with a mild cleaner
Run the extractor fan, wipe the joints dry after use, and clean them regularly with a mild cleaner to slow mould growth.
Don’t wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.

Prices and what affects them
You will not pay by the hour. The price is based on:
- How many areas need work
- Access to the area
- The material and finish
- Doing more than one item at once
A repair usually costs much less than people expect, especially compared with replacing and refitting. Send photos and we’ll give you the exact figure.
Send pictures for a quote
A couple of clear pictures is all it takes. Try to include:
- Good light, ideally daylight, without flash glare
- A picture taken from further back
- The material, if you know it
- A clear, close picture of the problem area
For a price in Coldharbour, the easiest route is pictures: one close up, one from further back, plus your postcode. We reply with a fixed quote and our next available dates.
How it works
Arrival times are agreed in advance. Once we’re there, the work takes around two hours for most jobs. We leave the room clean and you’ll know when it can be used.
- We protect the area and mask the joint lines.
- 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.
- The bead is smoothed, the tape removed and the seal left to cure.
Preparing for the visit

- Plan for the room to be out of bounds to pets and children
- Clear the area around the damage
Ask for a price
For most jobs, pictures are all we need to give you a price. Tell us what happened and where you are, and we’ll send back a fixed quote and some dates.
Advice
Why reseal now?
Resealing is routine maintenance. Putting off a reseal can let water reach the walls and floor, which costs far more to put right. Rather than charging by the hour, we price the entire job up front. Damage, material and access decide it, and doing several items at once reduces it.

What we cannot put right
Some jobs aren’t right for a repair, for example:
- A bath or tray that moves, until its support is fixed
- Very wide gaps that need a trim
- Tiles that move, until they’re refixed
If in doubt, send pictures and we will say what we think before you book.
