Most Sick Building Cases Are Caused by Failed Remediation - Not the Original Damage.

Untrained or uninsured contractors - and especially handyman - often leave behind hidden moisture, microbial amplification, soot residues, and cross contaminations. When homeowners hire handymen or uncertified workers to "save money" they unintentionally create Sick Building Syndrome conditions that lead directly to litigation. These shortcuts are not consistent with industry standards (S500, S520, S700) and produce chronic exposure symptoms attorneys see every day.

 

I provide neutral, litigation grade forensic inspections, that document how improper remediation created the exposure, not the event itself.    

 

Why Sick Building Syndrome Happens - And Why it Matters in Litigation

​

Improper mitigation leaves behind

• hidden moisture

• microbial amplification

• soot and combustion residues

• HVAC contamination

• cross-contamination

• chronic exposure conditions

​​

These failures create the symptoms attorneys see in their clients

• headaches

• respiratory irritation 

• chronic cough

• sinus inflammation

• fatigue

• cognitive fog

• odor sensitivity

 

My role is to document how failed water, mold, fire and smoke remediation created the exposure, providing neutral, litigation-grade evidence that strengthens causation, liability, and damages.  

 

Real - World Forensic Insight Attorneys Rely On

​

• Reframed an attorney's entire case from a phone consultation by identifying water damage indicator, and mycotoxin indicators in the opposing party own lab results, forcing the opposing side to pay for the damages that they caused.

• Exposed S520 inconsistent from homeowner's photos, including improper sequencing and cross contamination - proving the remediation itself caused the exposure.  

• Identified contractor shortcuts and non-consistent with the standards, that strengthened causation, liability, and damages arguments.

• Explained how handyman "repairs" create SBS conditions, helping attorneys understand why uncertified work leads to chronic exposure and litigation.
