Spray-Foam Insulation
Closed-cell polyurethane spray foam creates durable air barriers with R-value 6 per inch. Our Demilec HeatLok Soya solution insulates complex structures while meeting Canadian environmental standards. Ideal for new constructions, attics, and steel buildings, this eco-friendly option prevents air leakage and moisture penetration while improving energy efficiency.
Blown-In Cellulose
High-density fire-retardant cellulose provides superior thermal performance for residential and commercial spaces. Weathershield brand material maintains R-value over time without compaction. Particularly effective in attics and older homes with unique finishes, this 87% recycled-content solution resists mold, vermin, and ice damming while offering acoustic benefits.
Seamless Gutters
Custom aluminum gutter systems prevent water damage to foundations and exteriors. Our on-site fabrication ensures precise fitting for residential, commercial, and cottage properties. Designed to control water flow and protect against erosion, these durable systems maintain structural integrity while preventing staining and basement cracking through effective moisture management.
