At GDSI, we’re focused delivering high-quality results with end-to-end services. Quality control is more effectively managed and services are delivered more efficiently with our certified, in-house team.


While prohibited in new construction since 1978, contractors were allowed to exhaust their inventories of asbestos and, therefore, the substance can still be found in structures built as late as 1986. GDSI’s team will manage the abatement (removal) or remediation (safe encapsulation) of asbestos in your structure to exceed industry safety standards.


Lead-based paints can potentially create unhealthy environments in your structure.  The GDSI team manages this abatement process professionally, safely and efficiently.



Our Pacific Northwest climate provides wonderful living for us, but also ideal conditions for mold to grow. Left unattended, mold can potentially create toxic and unhealthy indoor environments. GDSI’s expert team will identify and remove mold, keeping your structure safe and healthy.
