Shower Resealing and Silicone Replacement
Cutting out failed, mouldy or peeling silicone around showers, baths and screens and resealing them properly, across Essex, Kent and East London.
Why silicone fails
Sealant is a maintenance item, not a lifetime one. Movement between the tray and the wall, harsh cleaning products and constant moisture all break the bond over time, and once water gets behind the bead, mould grows in the gap where cleaning cannot reach it.
Black mould that returns within days of scrubbing is almost always mould behind the silicone rather than on it. At that point no cleaner will fix it; the sealant has to come out and be replaced.
How we reseal a shower
The old silicone is cut out completely, including the parts hidden at the corners and behind the screen frame. The joint is then cleaned and dried properly, because new sealant will not bond to a damp or soapy surface, and only then is the new sanitary-grade silicone applied and tooled to a smooth, concave bead.
The shower then needs to stay dry while the sealant cures, typically overnight, and we will tell you exactly how long before you book. Rushing this stage is why so many resealing jobs fail within months.
More than the tray edge
A proper reseal covers every joint that keeps water in the showering area: the tray or bath edge, the vertical corners of the tiling, around the screen frame and along any panels. Doing one bead and leaving the others is a false economy, because the joint you skip is the one that leaks next.
Where tiles meet the bath, our bathroom fitting team handles resealing as part of wider work, and for full enclosure refits see shower installation.
When resealing is not enough
If water has been getting behind the sealant for a long time, the damage can run deeper: swollen plasterboard, loose tiles or staining on the ceiling below. We will always tell you honestly if the joint is a symptom rather than the whole problem.
Our guide to leaking shower causes and fixes helps you judge whether a leak is a sealing issue or something behind the wall before you book.
Booking a reseal
Resealing is a small, contained job and we group it sensibly with other work where that helps. Quotes are free and in writing, and the work carries our 1-year workmanship warranty. Call 01268 206409 or send a photograph of the joint through the quote form and we will confirm what is needed.
Keeping new sealant looking good
Once a shower has been resealed, a little care keeps it white for longer. Wiping the joint dry after use, ventilating the room and avoiding abrasive cleaners all slow the return of mould, and a quick squeegee of the screen takes seconds.
Even with good care, sealant in a daily-use shower is a wear item that will need refreshing again eventually. The difference is that a well prepared joint lasts years rather than months, and refreshing it stays a small job.
Frequently asked questions
Can you remove mould from silicone without replacing it?
Surface mould can be cleaned, but mould that keeps returning is growing behind the sealant. The lasting fix is to cut the old silicone out and reseal.
How long before I can use the shower after resealing?
The new sealant needs to cure fully, typically overnight. We confirm the exact time when booking so you can plan around it.
Do you reseal baths as well as showers?
Yes. Bath edges, basins, screens and tiled corners are all part of the same service.
Why did my last reseal fail so quickly?
Usually because the old sealant was not fully removed or the joint was not dry when the new bead went on. Preparation is most of the job.
