Sound Familiar?

We've heard it before.

The contractor disappeared mid-project.

Deposit paid. Work started. Then — silence. Calls go unanswered and the site sits idle.

TrioTimber assigns a dedicated PM reachable daily by phone and text.

Phase 2 cost double what Phase 1 quoted.

Every "surprise" triggers a change order. The budget doubles before demo is done.

We deliver line-item fixed-price contracts. Any scope adjustment is put in writing and agreed before work continues.

The permits were "handled"—until the inspector arrived.

Unpermitted work fails inspection, triggering stop-work orders and costly remediation.

We pull every permit and attend every inspection — zero exceptions.

TrioTimber operates with a written contract, line-item budgets, and licensed project managers on every job.
