The Most Common Speccing Mistake
It shows up on project budgets as a single line item: Finish Carpentry — $X,000. No material spec. No profile details. No sequencing notes. Just a number and an assumption that someone will figure it out.
For rough carpentry, framing, or general millwork, that approach can work. For finish carpentry — the work that’s visible, that homeowners and building occupants interact with every day — it almost always creates problems. Missed tolerances, material substitutions that affect the aesthetic, sequencing conflicts with other trades, and change orders that eat the contingency budget.
Finish carpentry is a specialty trade. It specs like one.
What a Good Finish Carpentry Spec Looks Like
A solid spec for finish carpentry work addresses four things:
1. Material specification: Profile type (MDF, finger-jointed pine, solid hardwood), dimensions, paint-grade vs. stain-grade, manufacturer or supplier reference where relevant. Vague specs like “wood paneling” leave room for substitutions that affect cost, appearance, and longevity.
2. Profile and design details: For wainscoting, shaker panels, coffered ceilings, or custom millwork — include a drawing or reference photo. Panel dimensions, reveal depths, rail and stile widths. The more specific, the fewer surprises at install.
3. Tolerances: Finish carpentry tolerances are tighter than rough work. Out-of-plumb walls, unlevel floors, and uneven ceilings are normal — but they need to be accounted for in the scope. A good finish carpenter expects imperfect substrate and works with it. A bad spec assumes perfect conditions.
4. Sequencing: Finish carpentry is almost always one of the last trades in. But “last” needs to be defined relative to paint, flooring, and fixture installation. The sequence matters: flooring before baseboard, paint before paneling profiles (in most cases), electrical rough-in and drywall well before any trim work begins. If this isn’t addressed in the spec or pre-construction meeting, you’ll get conflicts at the finish stage when schedule pressure is highest.
What to Look for in a Finish Carpentry Sub-Trade
A few markers that separate strong finish carpentry subs from the rest:
- They ask for a design render or detailed scope upfront — not just a room measurement. If a sub quotes finish carpentry from square footage alone without asking about profile details, that’s a flag.
- They sequence themselves. Good finish carpenters know where they fit in the trade stack and communicate proactively if something upstream (drywall texture, floor flatness, paint schedule) is going to affect their work.
- Their portfolio shows consistent tolerances. Look for tight miters, consistent reveals, and clean caulk lines. These aren’t aesthetic preferences — they’re indicators of how the work was measured and executed.
- They’re familiar with Calgary’s build environment. New builds, infills, and renovations each have different substrate challenges. A sub who works primarily in one context may struggle in another.
How We Work With GCs
At Calgary Custom Concepts, the majority of our commercial and multi-unit work comes from GC and developer referrals. Here’s what that relationship looks like in practice:
- We review plans and scope early — pre-construction if possible — to flag sequencing issues before they become field problems.
- We provide detailed material and profile specs that can go into your project documentation.
- We coordinate directly with your site super on scheduling and substrate readiness.
- We work across Calgary and surrounding areas including Airdrie, Cochrane, Okotoks, and Chestermere.
If you’re a GC looking for a finish carpentry sub-trade for an upcoming project — residential, multi-unit, or commercial — reach out directly: build@calgarycustomconcepts.ca or view our commercial work at calcustom.ca/installs.
