We can take the most serious situations from water damage and control the billions upon billions of mold spores present.  Removing a wall like this takes more than HEPA filtered airscrubbers,   negative air pressure and HEPA vacuums.
Crawl spaces are often neglected.  Moisture is hard but not impossible to control.  We have creative solutions to this common problem.
What happens if your containment did not take the other side of the wall into consideration when you were designing your containment?  Technology and knowledge of building sciences play a big role.
Stachybotrys may not appear on any air samples.  It may not show through the paint.  But people still suffer.  Knowledge and experience doesn't come from a 3 day training course for certification.
Old building practices can lead to microbial growth.  The plumbing can be fine and problems will still come.  Inspection from all points is a must.  Sacrificing attention to detail can affect the outcome in a negative way.
Building materials That are porous and support microbial growth must be removed.  Biocides and sealers can not replace good remediation techniques.  Biocides and sealers are very limited in what they can accomplish.
Remediation is hard work.  The suits are hot and wearing respirators makes breathing difficult.  This environment creates opurtunities to make mistakes.  Quality control is essential in an harsh enviroment where technicians may overlook surfaces.
We have worked with intricate wood furniture, antiques  and other heirlooms.
Paintings can be especially difficult in moldly environments. While no one can honestly claim to disinfect or sanitize these types of items,  we can decontaminate many of them so they can be enjoyed in a better environment.
Containment has to be constructed in a way that can withstand abuse and stay erect.  Technicians have to pass through the air locks with tools,  waste materials and use it as a changing room for Personal Protection Equipment (PPE).
Containment design has to take cross contamination into consideration.
It is hard to decontaminate in a filthy environment.  We can build a temporary cleanroom for decontamination.
