VERT / GREEN
Identify cladding, membrane, cavity, flashings and drainage exits before retrofit.
Rainscreen and wall drainage plane
Use cladding as the first line of defence while preserving a continuous path behind it to manage, drain and dry water that gets through.
JAUNE / YELLOW
A cavity bridged by mortar/debris, blocked weeps or discontinuous flashing turns a drained system into a water trap.
ROUGE / RED
Active leakage, discontinuous membrane/flashing or decay behind cladding: open enough to repair the water path, not just recaulk the face.

Special check related to this project
V14
Systems to check before closing the work
V14 connects envelope, air, fire, structure, water and code instead of treating each project in isolation.
V15
Remaining system checks not to miss
V15 covers issues that can block a project, cause a loss or become expensive once concealed.
V16
Advanced diagnostics to cross-check
V16 connects water, soil, climate, safety, materials and seasonal use to existing projects.
V17
Specialized systems to cross-check
V17 completes gas, soil, water, fire, climate and structural interfaces.
V18
Specialized diagnostics to verify
V18 connects systems that become costly or regulated when a primary project triggers them.
V19
Edge systems to integrate into the project
V19 covers interfaces that become important when multiple home systems interact.
Building interfaces to diagnose before enclosure or replacement
These tools connect structure, water, air, frost, wind and mechanical systems so repairs do not hide the cause.
V28
Finish and service details to verify
V28 connects small details that become costly once finishes are closed.
V47
V47 interfaces not to miss
These details are small on a drawing but can control water, structure or durability.
