How to Restore a Composite Door
Composite doors are made of 17 layers of laminated wood and a solid core. They are designed to keep you warm and safe. They are prone to damage from break-ins or other forces.
Common problems include cracks, misalignment of the door, and gaps around the frame. Fortunately, the majority of these issues are simple to repair!
Cracks
Composite doors are well-known for their durability. However, they may develop cracks or splits over time. They can be caused by general wear and tear or an impact that goes unnoticed or a change in temperature or humidity.
