Custom carpentry & interior remodeling in Martinsville, NJ
Martinsville is a quieter Somerset pocket near Bridgewater and Warren — single-family homes where families want better storage, updated baths, and rooms that finally work for how they live. ONYX brings owner-led carpentry and remodeling without the big-company runaround.
Carpentry & remodeling in Martinsville, NJ
Martinsville houses often need practical upgrades: a family room built-in that hides media clutter, a hall bath that still looks like 1995, or a partition wall that blocks natural light. ONYX scopes those jobs so cost and timeline stay honest from day one.
Our Design–Finish framework keeps even multi-trade projects organized — design and layout first, carpentry and construction second, then drywall, paint, and handover so you are not left coordinating punch lists alone.
Proximity from Warren means Martinsville clients get the same responsive site visits as our local Warren work. Rhett Mattson remains your single point of contact through completion.
