New wishes or unexpected conditions can arise during renovation. Record their effect on cost and time before proceeding.
Compare the complete intervention
Separate investigation, necessary repairs and improved access. Identify uncertainties in concealed areas, with an agreed decision point after opening them.
Describe the change
State what differs from the agreed scope and why. Use a drawing or photograph where helpful.
Decide this before construction
Assess the cause first, then establish the repair extent. Record concealed work before applying finishes and keep agreed inspection points clear.
How to review the result
Check the repair and future access together. Ask which signs deserve attention at the next inspection and where the relevant documentation is stored.
