Finish Carpentry Cost in Metro Detroit (2026)

Material grade is the first lever: paint-grade MDF and poplar cost less and install faster than stain-grade oak, maple, or walnut, where every joint shows and nothing can be caulked. Complexity is the second — plain base and casing go quickly, while coffered ceilings, panel walls, curved work, and built-ins with face frames take real time. The wildcard is the house itself. Plaster walls that bow, floors that slope, and corners that are 88 degrees instead of 90 all mean more scribing, and scribing is hours.

• Crown molding (one room): roughly $700–$1,800 installed depending on profile and ceiling height
• Window/door casing: often $90–$250 per opening
• Fireplace mantel & surround: $900–$3,500+ by material and detail
• Custom built-ins: commonly $1,500–$6,000+ per wall

Stain-grade versions of any of these sit at the higher end because the joinery has to be flawless.

Ask the carpenter to spell out the material grade, the profiles, and whether finishing (paint or stain) is included or handled separately — many finish carpenters install bare and leave painting to a painter. A clear scope that names species and reveals protects you from the vague hourly estimate that balloons once the work starts. When we match you with a carpenter, you get an itemized number you can actually compare against another bid.
