The attic had mold formation, was extremely cold in winter, and very hot in summer. Specialist Karim identified the causes as insufficient insulation, air leaks, and poor ventilation, leading to health risks and structural damage. We removed the old insulation, identified and sealed all sources of air leaks, and removed mold spores. Using high-quality ZypFoam sealant, we closed gaps to prevent air leakage and installed new TruSoft cellulose insulation, achieving a thermal value of R60. This resulted in significant reductions in heating and cooling costs, elimination of moisture build-up, and a mold-free, energy-efficient, and comfortable attic.
