As a painting estimator, your responsibilities are to prepare detailed cost estimates that can be used to bid on residential and commercial painting jobs. Your duties include examining structures and buildings, understanding the techniques needed to paint different types of homes, and accounting for various elements of building construction that can make the painting more challenging. Painting estimators often collaborate with engineers and architects, review and validate cost estimates using technology, negotiate bids for subcontractors, provide information to site personnel and potential customers, and organize bid information for future reference. Estimators at large companies may focus entirely on this job, while estimators at small companies switch between this role and working as a painter.
