Commercial Junior Estimator

Wiehler Mechanical 's commercial department is growing, and we're adding a Junior Estimator to our estimating team. You'll learn the trade side of the business from the ground up, working directly with our Senior Estimator on plumbing bids for general contractors and owners.

This role has a clear path forward. Many estimators grow into senior estimating or project management, and we want to help you get there.

What You'll Do Reporting to the Senior Estimator, you'll own the take-off work that keeps our bids accurate and on time.

• Complete quantity take-offs for commercial plumbing projects in our estimating software (fixtures, piping, fittings, valves and equipment)
• Track bid deadlines, addenda and drawing revisions so nothing gets missed
• Send requests for quotes to suppliers and subtrades, and follow up so pricing arrives on time
• Review each quote against the full scope and flag gaps or exclusions to the Senior Estimator
• Keep project files organized and help maintain our material pricing and labour databases

What You Bring Must have

• 1+ year of plumbing or mechanical experience, in the field or the office
• Ability to read plumbing and mechanical drawings
• Comfort working in software and on the computer all day
• Strong attention to detail; you catch the missing valve before it costs us
• Clear, confident communication with suppliers and your team

Nice to have

• Mechanical engineering education
• Journeyperson plumber ticket, or a current indentured apprentice
• Experience with estimating or take-off software

What we offer

• $55,000–$65,000 per year
• Full-time, Monday to Friday, 40 hours per week
• Flexible start and finish times
• Office-based, with potential for hybrid work
• Health and Dental benefits, and a matching RRSP program
• One-on-one mentorship from a Senior Estimator
• A clear growth path into senior estimating or project management
• A place on a growing commercial team

The role is mostly office-based. Occasional site visits come later, with a hard hat, safety vest and steel-toed boots.
