FAQ
Do new builds need plumbing and wiring replacement?
Generally not — new build plumbing and wiring meet current standards with developer warranty. However, test all water and electrical points during inspection and request free rectification within the warranty period if issues are found.
Where do secondhand flat renovations most commonly go over budget?
The most common overruns come from hidden problems discovered after demolition — such as internal wall leaks, ceiling concrete spalling, and rusted old iron pipes. Reserve 15-20% of the budget as contingency for unexpected issues.
