The clause is written years before anyone reads it properly
Condition and make-good provisions are agreed at the start of a lease when neither party is thinking about the end of it. Five years later the tenant reads them as ordinary cleanliness and the landlord reads them as restoration, and both are working from the same sentence. A cleaning contractor cannot resolve that difference and should not pretend to. Both parties are reading in good faith and reaching opposite conclusions.
What a contractor can do is scope precisely what will be done, in language that maps to areas and surfaces rather than to adjectives. A quote that says the warehouse floor will be machine scrubbed, the racking wiped to a stated height, the office areas detailed and the amenities fully serviced gives both parties something concrete to compare against the lease. Specificity is the only thing that reliably shortens a handback discussion.
