• Interpret drawings, specs, and site conditions to determine labour, materials, and equipment requirements
• Identify risks such as access, shutdowns, tie-ins, and unknown conditions
• Work with office team to issue quotes through CRM (Jobber or similar)
• Assist in improving pricing accuracy, margins, and close rates

What We’re Looking For
• 3+ years experience in plumbing and/or mechanical estimating
• Strong understanding of:

Compensation

• Performance-based incentives tied to closed work and profitability
• Flexible schedule (ideal for experienced estimators or semi-retired professionals)

Why Join Us
• Growing Plumbing & HVAC company expanding into commercial mechanical services
• Opportunity to work on both service and project-based estimating
• Direct involvement in building systems, pricing structure, and workflows
• Strong pipeline of property management and commercial clients
