Field notes · from the foreman’s log

We don’t have public reviews yet. Here’s what the crew wrote down instead.

CJ Contractors & Painting is rebuilding its public review presence in 2026. Until then, these are the foreman’s field notes — not invented customer quotes.

  1. F-NOTE / 012025-02-14

    Sand Lake garage demising wall

    Two-hour assembly. Crew flagged the existing top-plate gap before board went up — sealed and re-inspected. Sometimes the most important drywall decision happens before the first sheet hangs.

    — Foreman log
  2. F-NOTE / 022024-11-03

    Hillside primary suite

    Raking light off the south windows turned an ordinary Level-4 finish into a problem. Came back with skim, re-sanded under work lights, and re-inspected at 8 am sun. The seam disappears at every hour now.

    — QC pass
  3. F-NOTE / 032024-08-22

    Eagle River basement build-out

    Mechanical room shares a wall with the new bunk room. Spec called STC 35; we proposed STC 50 with resilient channel and mineral wool. Owner can’t hear the boiler kick anymore.
