Voorhees, Marlton, Haddon Heights, and Berlin face winter moisture caused by soil expansion, frozen ground, and increased indoor humidity. If a basement isn’t waterproofed properly, moisture can enter through foundation walls, slab cracks, or unsealed window wells.
Subterra specializes in:
• Sump pump systems
• Interior French drains
• Foundation crack repair
• Egress window installation
• Mold-resistant insulation
• Full basement finishing
Waterproofing is best done before winter soil saturation peaks. Even finished basements can develop mold behind drywall within days if moisture intrudes. The EPA warns (https://www.epa.gov/mold) that basements are one of the highest-risk areas for toxic mold growth—and early prevention is the key.
If you’re planning to finish your basement in 2026, waterproofing should be your first step.
