Exterior Insulation

Exterior insulation transforms drafty Ontario brick homes into energy-efficient buildings while preserving interior space and architectural details—when properly integrated with moisture management systems. This approach places insulation outside the structure, keeping masonry warm and dry while eliminating thermal bridges that waste energy and cause condensation problems. Options include EIFS (synthetic stucco), mineral wool boards, or spray foam systems, each requiring careful detailing to prevent moisture entrapment that destroys brick and framing. Critical considerations include maintaining drainage planes, installing proper air barriers, and ensuring vapor permeability appropriate for existing wall assemblies. Improperly installed exterior insulation causes hidden rot, mold growth, and accelerated masonry deterioration from trapped moisture. Fix My Brick coordinates insulation upgrades with necessary masonry repairs, ensuring walls are sound before covering and drainage systems function properly. Professional installation following building science principles can reduce heating costs by 30-40% while preventing moisture problems that plague DIY attempts.
