Questions? You’re covered

What is the difference between outsourcing and hiring an in-house estimator?

Outsourcing removes the fixed cost of salaries, software licenses, and training. You pay per project instead, which works better for contractors with variable bid volume rather than a constant pipeline that justifies a full-time hire.

Turnaround depends on project size and scope, but most bid-stage estimates are delivered within a few business days. Tight deadlines can often be accommodated with advance notice.

Yes. Every project we take on is handled under strict confidentiality, and drawings or specifications are never shared outside our estimating team.

We are always ready to help you and answer your questions
