How to sell to contractors in Rockville

This category covers general contractors, renovation firms, builders, excavators and concrete and framing companies. Projects are larger and longer, and the person you need is usually the owner or the estimator.

Who sells to contractors

  • Construction software (estimating, scheduling, takeoffs, project management)
  • Equipment rental and heavy-equipment dealers
  • Building-materials suppliers
  • Bonding, builder's risk and liability insurance
  • Accounting and job-costing firms
  • Subcontractor and trade recruiting

What keeps owners up at night

  • Cash flow between progress payments
  • Bidding accurately and winning the right jobs
  • Coordinating subs and keeping schedules
  • Labour shortages
When to reach themEarly morning, before site visits, or late afternoon. Winter is planning and bidding season in colder markets, which is a good time to sell software and services.
The angle that worksTalk about margin and schedule risk. "How much did your last job overrun?" opens more doors than "we save you time."
Reaching out in the USB2B cold email is governed by CAN-SPAM: honest headers and subject lines, a physical address and an opt-out you honor. Phone outreach has its own rules, especially for cell phones. Read our CAN-SPAM guide and cold-calling rules before you start.
