Shower screen leaks and resealing assessment
A local screen-perimeter repair may be suitable if assessment identifies an accessible failed joint as the water path. Tell us whether water first appears at the screen base, beside the door or outside a tiled corner. The screen arrangement and its drainage details need consideration before deciding which joints should be sealed. Adding silicone wherever water is visible can miss the actual entry point.
Old silicone removal before joint resealing
We check the joint and bonding surfaces, then identify the failed material to remove and the preparation needed for the replacement sealant. Our scope lists the shower-screen edges or tiled junctions being repaired and the surrounding surfaces to retain. Loose grout, damaged tiles or movement may change the work needed.
Silicone repair and concealed membrane failure
Silicone is a joint sealant; it does not replace the membrane beneath tiled finishes. If moisture continues beyond the shower or returns after a surface repair, use the leaking shower assessment service to review the cause. The repair options guide explains when grout, sealant or broader waterproofing work may be relevant. Describe the affected joints before choosing a repair.
Shower grout and silicone repair suitability
We check missing grout between tiles, split silicone at changes of plane, screen junctions and signs of tile movement. Old silicone, residue and damp joint surfaces affect preparation and the bond of the replacement sealant.
Grout fills tile joints; flexible sealant serves movement joints. Neither treatment repairs a concealed membrane failure or a plumbing leak. Persistent moisture after a previous surface repair needs reassessment before more grout or silicone is applied.
Grout and silicone repair scope
Our quote identifies the joints, grout removal depth, preparation and replacement materials. We check tiles and the substrate and include the repairs needed to prepare a sound base for regrouting. We protect neighbouring finishes, remove loose residue, prepare the joint profile and explain cleaning and curing requirements for the renewed surface.
- Inspection of grout, silicone, screen edges and other accessible shower junctions.
- Removal of failed sealant or grout from the defined repair area.
- New grout, silicone and agreed finishing work, or a clear recommendation when broader waterproofing is required.
Shower joint preparation, curing and reuse
- Identify the worn grout or silicone joints and describe any leak that continued after earlier repairs.
- Agree removal of old silicone or deteriorated grout, cleaning and drying before the selected repair.
- Keep the shower out of use for the specified preparation and curing periods, then follow the written handover instructions.
For tiled floors outside the shower, use our tile regrouting service. For material choices, compare epoxy and cement-based grout; outdoor balcony joints belong with the balcony repair scope.

Shower silicone replacement and regrouting have different jobs
Use this service for suitable exposed silicone joints or grout between sound tiles. The agreed work identifies the joints, old material removal, preparation, replacement product and shower curing period.
Renewing failed flexible shower sealant
Flexible corners and screen-perimeter joints need a compatible sealant and suitable joint preparation. We define the joints being renewed and explain the drying and curing instructions for those materials.
Renewing grout between tiles
Our team renews worn grout and checks nearby seals and tiled junctions at the same time. Where the leak involves the membrane beneath the tiles, we plan the access, preparation, waterproofing and reinstatement needed, so the repair addresses the affected construction as well as the visible finish. For recurring moisture, use leak assessment before another surface repair to review the source and repair plan.
Tell us which joints have split or opened and whether there is water beyond the shower. We confirm suitability and shower downtime before agreeing the work.

Grout, sealant and bond breakers are not interchangeable
Grout fills appropriate fixed tile joints. Flexible sealants and bond breakers form part of specified movement-joint or membrane details; they are not substitutes for grout across a tiled floor. Product compatibility and the condition found on site determine the choice. See tile regrouting and epoxy grout options for tiled areas beyond the shower, or the Sika waterproofing guidance for the role of bond breakers.
