Matthew Marentic

Estimator @ Mattamy Homes

About

I’m an Estimator with experience in low-rise residential construction, currently working at Mattamy Homes. I specialize in preparing detailed cost estimates, quantity takeoffs, and project budgets aligned with current market conditions. Through my work, I’ve supported multiple high-volume subdivisions, including projects exceeding 400 units and $100M in value. I enjoy working closely with subcontractors, site teams, and internal departments to ensure estimates are accurate, competitive, and practical from both a cost and constructability perspective. I’m particularly interested in improving estimating accuracy through data, standardization (CSI MasterFormat), and value engineering. Always looking to learn, take on more responsibility, and contribute to efficient project delivery.
