Cornerstone Restoration is widely recognized for attention to detail, top notch quality and strong communication skills before and during the restoration process. Unqualified contractors jeopardize property and create costly mortar removals through lack of care, knowledge, experience and poor execution during the restoration process. Brick restoration is not like new construction or ‘renovation’, as the existing structure must be respected and understood as a unique state-of-being. Each project is approached with expert craftsmanship to create a beautiful, lasting restoration. We love what we do!
