Record the water pattern without trying to prove the cause
Tell the assessor where water or damp appears, when it was first noticed and whether it follows shower use or also occurs at other times. Include previous resealing, regrouting or plumbing repairs. A dated description is useful even if you have no photos. Do not run water deliberately to recreate damage or remove tiles to look for the leak.
A failed visible joint may need replacement, but its appearance alone cannot locate every path that water takes. Damp in the room next door, loose tiles or continued leakage after previous surface work widens the assessment. Plumbing, the supporting surface and the waterproofing system may need separate consideration. Keep water away from electrical risks and arrange appropriate help where safety is affected.
Compare a surface repair with a wider wet-area scope
A resealing proposal concerns the specified surface joints. Regrouting concerns the tile joints. Neither label alone means that concealed waterproofing has been inspected or replaced. Ask what finding supports the proposed repair and what remains uncertain. If investigation identifies a deeper defect, repeated surface work may delay the repair that is actually needed.
A wider wet-area proposal may involve removal, substrate assessment, waterproofing, tiling and finishing, with dependencies between stages. The written scope should explain the boundaries, any separate plumbing work and how newly exposed damage will be quoted and approved. Confirm when the area can be used again with the attending team; do not assume it is ready because the surface looks dry. Product requirements and the actual repair determine the return-to-use instructions.
Split shower silicone and surface joints
Silicone is commonly used at movement joints and changes of plane in a tiled wet area. A split or deteriorated joint may need surface resealing, but its appearance does not establish the condition of the system behind the tiles. Describe staining, gaps and whether the shower leaks during use. We assess the source of a leak before recommending surface resealing or further wet-area repairs.
Missing tile grout and loose tiles
Grout fills joints between tiles, while the underlying waterproofing is a separate part of the construction. Missing grout, loose tiles or recurring cracking may need more investigation than refilling visible gaps. Note whether tiles have moved and whether damp appears outside the shower. Tell us about previous regrouting or resealing and whether it changed the symptoms. Movement and backing condition affect the appropriate work.
Failed shower waterproofing and adjoining-room damp
Water appearing in a bedroom or below a tiled balcony may come from several sources. Plumbing, drainage, surface joints and the underlying wet-area system should be considered during assessment. Where deeper failure is identified, investigation and repairs may involve tile removal, substrate work, waterproofing and retiling. Those are distinct from surface maintenance and need an agreed scope; the visible stain alone cannot determine the complete repair.
What to ask before accepting a shower repair quote
Explain where water appears, when it happens and which repairs have already been attempted. Ask what has been assessed, what remains unknown and which surface or underlying work is included. Confirm how additional damage will be reported and approved. For apartments, include affected neighbouring areas and access arrangements. Avoid treating a maintenance quote as proof that every concealed component is sound.
Common Repair Questions
What is the difference between grout and silicone?
Grout and silicone serve different joint requirements in a tiled finish. Neither is a substitute for assessing the waterproofing beneath the tiles. The appropriate material and repair depend on the joint and condition.
How is resealing different from waterproofing a shower?
Resealing addresses specified surface joints. Waterproofing repairs address the underlying wet-area system and may involve removing and reinstating finishes. The required work follows assessment of the leak.
Why does a shower still leak after new silicone?
The leak may involve another joint, plumbing, movement or the underlying waterproofing. Report what was resealed and where damp persists. Repeating the same surface treatment without assessment may leave the cause unresolved.
Split Shower Silicone & Missing Tile Grout
Can replacing shower silicone fix every shower leak?
No. Replacing silicone only addresses the surface joint included in the work. A leaking shower may also have failed waterproofing, plumbing faults or movement beneath the tiles. We assess the symptoms before quoting resealing, regrouting or further investigation.
Can you assess black silicone around the shower base?
Yes. Explain whether there is staining only, split joints, loose tiles or damp in an adjoining room. We check the joint condition and signs of water entry before agreeing the surface repair. If moisture points to a deeper problem, we discuss the further investigation and repairs needed.
Cracked Floor Tiles & Loose Tile Repairs
Can just one cracked floor tile be replaced?
A local replacement may be possible where a suitable tile is available and the surrounding floor is sound. We check why it cracked and the supporting surface before quoting. Recurring cracks, movement or moisture should be investigated instead of repeatedly replacing a tile.
Can you assess a loose splashback tile behind the sink?
Yes. Tell us whether the tile has moved, grout is missing or the wall is damp. We inspect the tile and backing before agreeing a local repair. Leaking plumbing or damaged backing must be considered separately from the visible tile finish.
Failed Shower Waterproofing & Balcony Leak Assessment
When does a shower repair need tiles removed and waterproofing redone?
Tile removal and waterproofing repairs may be needed where assessment identifies failure beneath the surface. New silicone cannot establish that the underlying membrane is sound. We confirm the investigation, repair sequence and scope before quoting the work.
Can you assess a shower leaking into the adjoining bedroom?
Yes. Describe where damp appears, when it occurs and whether previous resealing helped. The assessment considers plumbing, joints and the tiled wet-area system. Surface resealing, waterproofing and retiling are distinct works; the cause should be established before choosing the repair.

What to take from this guide
Silicone seals specified surface joints, grout fills tile joints and waterproofing concerns the wider wet-area system. Continued leaking after a reseal requires reassessment before further surface work. Record the water pattern and earlier work, then agree whether the investigation concerns joints, plumbing or deeper construction. The FAQ questions compare those possibilities; the waterproofing service explains the wider assessment scope. Follow the assessed repair and return-to-use instructions before using the area again.
