Wetherholt & Associates, Inc.

Wetherholt & Associates is a consulting firm that specializes in roofing, waterproofing and building enclosure problems, mostly for commercial, institutional and public-sector owners. Founded in 1984 to help resolve water intrusion issues in construction, the firm offers inspections, forensic analysis, design review, leak investigation, moisture surveys and specifications, and it also handles concrete consulting, wood decay investigations and interior condensation and ventilation problems.

The firm works as an independent advisor rather than a contractor, and its clients include several major school districts, manufacturing companies and municipal and state government departments. Its work sometimes leads to disputes, and it has also been retained as expert witnesses and expert mediators. The office is in Redmond, Washington, and the firm lists a phone number for new projects and employment inquiries.
