New wishes or unexpected conditions can arise during renovation. Record their effect on cost and time before proceeding.
Compare the complete intervention
Include internal making good and possible sill adjustments with facade work. Compare options using the complete work package around the opening.
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 existing detail before selecting products. Then coordinate insulation, ventilation and visible finishes so one improvement does not create an unexamined consequence elsewhere.
How to review the result
Compare the completed window arrangement with the approved drawing. Then check operation and adjoining internal finishes, including areas not visible in the elevation.
