IMPORTANT: If basement lowering is not done correctly, the basement excavation could damage or undermine the foundation and lead to from minor drywall damage to a collapse of your home. Therefore, a basement dig out must be done by a professional basement foundation contractor who is knowledgeable, licensed, equipped and experienced.
