Pricing guide
Costs vary mainly with the chosen scope: a surface renewal is generally simpler than a full removal and rebuild, while localised substrate repairs add extra time and materials. Labour hours, callout charges and any need to remove and dispose of old finishes also influence the final price, and after-hours attendance usually increases cost.
Work scope selected
A surface-renewal job typically requires less time and waste handling than a full remove-and-replace with a new waterproofing build-up.
Substrate condition and repairs
Localised patching, screed re-profiling or timber replacement before membrane application increases labour and material needs.
Demolition and waste handling
Removing tiles and old membrane generates more debris and requires additional labour and waste allowances compared with simple surface prep.
Need for additional trades
Some repairs may need carpentry or concreting work, which typically requires coordination and can extend the project timeline.
Callout and labour timing
Quoted labour hours usually cover tradesman time only, and callouts or after-hours work generally affect the overall charge.
