5 Best Home Inspection Companies in Singapore (2026)

A1 Defects Inspection runs BTO and private-property defect inspections across Singapore, sending teams of multiple inspectors to complete a full unit check in roughly an hour, then following through developer rectification and a second walk-through. Reviewers describe crews of three or four inspectors working simultaneously, explaining each defect on the spot and recording video documentation for the homeowner's reference. Its review count, 2,925, dwarfs every other business on this list, spanning BTO projects named directly by reviewers, Bishan Ridges, UrbanVille, Clementi Peaks, and more. It has no published site text summarising credentials, but the sheer volume and consistency of five-star reviews across many different projects is itself the strongest signal here.

SG DefectScan runs Defect Liability Period inspections, pre- and post-renovation checks, and tenancy inspections for HDB, condo, and landed properties, and its own site claims BCA CONQUAS certification along with coverage on Channel NewsAsia, Channel 5, and The Straits Times. Reviewers name specific inspectors, including Mr Raja, Mr Bashir, and Mr BK, for catching defects a first-time buyer would otherwise miss, down to bubbles in a window glass panel. One detailed review from a first-time HDB owner describes the company essentially acting as a personal assistant, liaising directly with the Building Service Centre on the homeowner's behalf. It positions itself explicitly around certification and media credibility rather than pure volume.

Advance Inspection specialises in architectural inspections, data line inspections, and window inspections, alongside its core property defects inspection and IAQ and formaldehyde testing services, following BCA Singapore guidelines. Reviewers overwhelmingly credit one inspector by name, Ben Lee, for catching defects other first-time buyers say they would have completely missed, often described as effectively a one-person operation handling the inspection personally rather than delegating it. Multiple reviews across different BTO projects, Lumina Grand and McNair Heights among them, describe the same pattern: fast, detailed defect reports delivered the same day or within twelve hours. The consistency of a single named inspector across almost every review is unusual on this list and appears to be a deliberate part of the company's model.

W&W Inspection is a BCA CONQUAS-certified home defect inspection provider whose own site cites over 3,000 inspections and nine years of combined building, structural, and M&E engineering experience across its team. Reviewers name inspector Richard almost exclusively, describing him as identifying dozens of defects per unit, in one case 52 on a first check, and personally liaising with contractors and the Building Service Centre through to rectification. One detailed review describes a three-trip package combining the first two visits into one to save the homeowner time, with all defects rectified inside twelve working days. The company also runs a referral cashback programme, mentioned directly by more than one reviewer as a reason they returned or referred others.

Absolute Inspection describes itself as Singapore's first RICS-certified defects inspection firm, established in 2015, which it says allows recognition across formal dispute resolution platforms including the Small Claims Tribunal and State Court. Reviewers describe a structured three-appointment process, first inspection, a joint inspection with the Building Service Centre, and a final rectification check, with different named inspectors, Fabien, Lucas, Gavin, and Steve, handling different stages. One detailed critical review from a customer whose inspection was a gift from a property agent describes the company missing marble gap defects near a ceiling that required later intervention, a claim the company responded to directly and asked to verify against its records. Most reviews describe a thorough, methodical process, with the one detailed negative review standing out as an exception rather than a pattern.
