Renovation does not mean demolishing everything. Fixtures, finishes and non-load-bearing partitions can be removed selectively. Retained areas, access and dust control are defined beforehand. Any work on a load-bearing element requires a specific assessment by a structural specialist.
To strip out a kitchen, bathroom or apartment, distinguish fixtures, finishes and their substrates. A partition has a different role from a load-bearing wall. Items to salvage and rooms still in use must be included in the scope.
Points to clarify for your quote
Describe the work room by room and identify doors, stairs or fixtures to keep. Separate removal of finishes, removal of substrates and new installations. Discuss storage of salvaged items and the waste route through shared areas before work. For an apartment, provide the co-ownership’s access rules and the protection expected in communal spaces.
