When should siding or exterior cladding be replaced?

Signs of wear

• Split, warped or loose boards
• Rot or crumbling material
• Water stains or mould inside exterior walls
• More and more frequent repairs

Repair or replace?

Localized damage can often be repaired. When several walls are affected or water has reached the materials behind the siding, replacement also allows membranes and flashing to be redone.

To check

• Permits required by your municipality
• Colour or material rules in some areas
• The season for the work
