New wishes or unexpected conditions can arise during renovation. Record their effect on cost and time before proceeding.
Compare the complete intervention
Compare purchase and recurring maintenance costs. Ask about preparation, fixings and access; the material price per square metre alone gives insufficient guidance.
Describe the change
State what differs from the agreed scope and why. Use a drawing or photograph where helpful.
Decide this before construction
Select the material early enough to design edges and fixings around it. Review a sample in its intended location before placing the full order.
How to review the result
Assess variation against the agreed sample and product information. Distinguish natural differences from damage or an incorrectly executed junction.
