The quality and usefulness of any inspection depends upon the knowledge and experience of the person who conducts the inspection.

While Texas has established some minimum standards for home inspections, the building inspection industry is still largely unregulated. The extent and quality of the home inspection, report, and follow-up assistance vary significantly. So do the expertise and credentials of the inspectors.

Criterium-Williams Engineers exceeds the minimum state requirements. As part of the Criterium-Engineers network, we have access to over 120 licensed professional engineers with decades of specialized experence in building structural, mechanical and electrical systems.

All of Criterium-Williams Engineers' inspections are performed by licensed Professional Engineers (P.E.).

The P.E. license is awarded by each state and is your assurance that the engineer is knowledgeable, ethical, and accountable. Accountability is a true measure of commitment to one's profession and clients.
