You are at the finish line. The drywall is up, the custom millwork is installed, and the high-end finishes are finally in place. For General Contractors and Property Developers in Vancouver, this is the most critical window: the gap between a “finished” construction site and a livable space ready for anoccupancy permit. The final clean is the bridge to that permit. However, many project managers treat cleaning as an afterthought, often hiring the lowest bidder, the “trunk slammers” who show up with a bucket and a household vacuum rather than a professional commercial cleaning crew. A poor cleaning job is more than just a nuisance; it is a financial and legal liability. It can lead to failed inspections, permanent damage to expensive finishes (like scratched tempered glass), and the lingering presence of hazardous silica dust. To protect your investment, you must know how to spot an unqualified vendor.
