Basement Cleaned in Place in Ridgefield, 2,100 Square Feet and Nothing Torn Out

The most useful thing about this Ridgefield project is what is missing from the invoice. There is no drywall removal line. No insulation tear out. No disposal of building materials beyond a single debris haul. On a job that ran $6,292.42 across an entire basement, nothing structural was removed. It was all cleaned in place. That is worth understanding, because the reflex assumption about mould work is that it means demolition, and a homeowner who expects demolition often ends up buying it whether the condition called for it or not. What the condition called for here was surface cleaning at scale.

The same 2,100 square feet appears three times in the scope, and the repetition is the method rather than a billing quirk. First, HEPA vacuuming in detail across 2,100 square feet, which lifts loose material off the wood into a sealed filter. Second, 2,100 square feet of stud wall cleaned heavy, which is a hand process on vertical framing. Third, 2,100 square feet of joist system cleaned, which is the overhead work and the slowest part of any basement, because a joist system is not a flat plane.

It is a repeating set of three sided bays with wiring, pipe and duct running through them, and cleaning it properly means working every bay rather than passing a vacuum along the underside. Vacuum, then walls, then ceiling structure, over the same footprint each time. Containment was modest at 110 square feet with two zipper doors, because the work zone was the basement itself rather than a room inside a finished house. Four 24 hour negative air periods ran across the job with 25 linear feet of lay flat ducting carrying scrubber exhaust out of the space, which matters more when nothing is being removed.

In a demolition job much of the contamination leaves in bags. In a cleaning job all of it becomes airborne at the moment of cleaning and the only route out is the filter. Contents were manipulated rather than discarded, in line with the instruction, which asked for the joist system and some contents to be cleaned. The crew notes read exactly as the work sounds: start cleaning joist system, continue cleaning joist system, continue cleaning. Three days of the same patient work across the same 2,100 square feet. What was not part of this project should be stated plainly. No antimicrobial coating and no encapsulation were sold or applied.

No testing, air sampling or clearance testing was performed. The basement was cleaned and handed back unfinished, exactly as it was found minus what came off it.
