Main Contractor Vs Managing Trades: Homeowner Guide

By John · 30 March 2026

Two Ways to Build

Main Contractor Vs Managing Trades: Homeowner Guide matters most when a homeowner is close to making a decision and does not want a vague quote, soft assumption, or missing line item to become an expensive problem later.

Option 1: Main Contractor

You hire one company. They manage everything.

Pros:

  • Single point of responsibility.
  • They coordinate all trades.
  • They fix problems.
  • Less stress for you.
  • Clearer warranty.

Cons:

  • 15-25% markup on all work.
  • Less control over who does what.
  • You're trusting their judgement.

Option 2: Self-Managing

You hire each trade separately: groundworker, bricklayer, roofer, electrician, plumber, plasterer, etc.

Pros:

  • Save the contractor markup.
  • Choose exactly who you want.
  • More control.

Cons:

  • YOU coordinate timing.
  • YOU fix problems between trades.
  • No single warranty.
  • Requires knowledge and time.
  • Trades may blame each other.

The Hidden Costs of Self-Managing

  • Your time (easily 10-20 hours/week).
  • Mistakes from poor coordination.
  • Trades not showing up when needed.
  • Disputes between trades.
  • No comeback if something goes wrong.

My Recommendation

For most homeowners: use a main contractor.

The markup is worth it for the reduced stress and clear accountability.

Self-manage only if you have:

  • Construction experience.
  • Significant time available.
  • Good trade contacts.
  • Tolerance for stress.
