Even the most skilled do it yourself home handyman requires the skills of a professional finish carpenter or trim carpenter on occasion. For instance, creating and installing custom cabinetry, custom oak trim, or fireplace mantle construction.

Staircase design and installation is another area often requiring the services of a skilled professional. Especially when a curved staircase or spiral staircase plan with custom staircase spindles is required. In that case, more than a carpenter is sometimes desired. A finish or master finish carpenter might be best, depending upon complexity of staircase design.
