First Fix Carpentry in Cornwall

First fix carpentry forms the structural backbone of any build, renovation, or extension project. At Kernowson Carpentry, we deliver precise, reliable first fix carpentry services across Cornwall, ensuring your project is set up correctly from the start.

What is First Fix Carpentry?

First fix carpentry refers to all structural timber work completed before plastering and finishing. This stage defines the layout, strength, and alignment of the building.

It typically includes:

  • Stud walls and internal framing
  • Roof structures and joists
  • Floor joists and subfloor construction
  • Door frames and structural openings

Getting this phase right is critical—errors here impact every trade that follows
