Siding replacement in Ontario is as much about moisture management as aesthetics. The weather-resistant barrier (WRB/house wrap) behind the cladding is where most failures originate — a ventilated rain screen cavity (min 3/8") is best practice for all siding types.
Material options and GTA pricing (2026):
Vinyl siding: $6-$12/sq ft installed (standard); $10-$18 for insulated vinyl. Full house 1,500-1,800 sq ft: $12,000-$25,000. Low maintenance, no painting.
Fibre cement (Hardie Board): $14-$22/sq ft installed. Full house: $22,000-$40,000. Superior fire resistance and paint retention. All field cuts must be primed before installation.
Brick veneer: $30-$50/sq ft. Heritage-appropriate, highest durability. Requires proper weep screed and flashing at base.
Manufactured stone veneer: $20-$40/sq ft. Attractive but moisture-sensitive — flashing and weep screed installation is critical.
Key installation detail: House wrap must be lapped shingle-fashion bottom to top, taped at all seams, and integrated with window and door flashings. This step is where budget contractors cut corners.
