Plumber vs. Builder: Who Handles What in Bathroom and Kitchen Repairs?
When repairing a burst pipe embedded inside a tiled wall or renovating a bathroom, homeowners often wonder who is responsible for chasing the wall, replacing pipework, waterproofing, and retiling. Clarifying trade boundaries prevents misunderstandings and budget disputes.
The Plumber's Core Scope of Work
A licensed plumber is exclusively responsible for the hydraulic, sanitary, and gas installations:
1. Locating hidden leaks using acoustic geophones and thermal cameras.
2. Cutting, fitting, soldering, and press-crimping supply pipes (copper, multilayer, PEX).
3. Installing and aligning drainage waste pipes and traps with correct gravitational slopes.
4. Mounting sanitary fixtures (toilets, basins, bidet valves, shower mixers).
5. Performing pressure tightness testing to guarantee zero leaks before walls are closed.
The Builder's (Mason/Tiler) Scope of Work
The builder or tiler handles structural masonry, surface finishes, and sealing:
1. Chasing wall channels (grooves) and breaking floor slabs for pipe passage.
2. Applying liquid waterproofing membranes under shower trays and wet room walls.
3. Backfilling chases with mortar and plastering walls flush.
4. Laying wall tiles, porcelain floor tiles, and applying waterproof silicone grouting.
How Hidden Leak Repairs Are Coordinated with Insurance
When repairing a pipe burst inside a wall, standard insurance coverage operates in three distinct phases: leak detection and pipe repair (plumber), drying and moisture remediation, and aesthetic restoration of masonry/tiles (builder/painter).
FAQ
Does a plumber repair the tiles after fixing an in-wall pipe burst?
Plumbers generally perform the opening of the chase and the pipe repair. Wall plastering and precision tile replacement are typically handled by a builder or your insurance restoration contractor.
Can I supply my own sanitary fixtures for the plumber to install?
Yes. Most plumbers will happily install taps, vanity units, and toilets supplied by the client, billing only for labor and connection fittings.
