Modern (18 year old) house, door has been strained too far open by big dog! The frame at the point of the topmost hinge of 3 has split over a length of about 6 inches equidistant top and bottom of the hinge. the crack then peters out back into unsplit timber. What's the best way to make a permanent repair? I was thinking of removing the door and hinges from the frame, slightly opening the gap up by inserting a slim chisel blade or similar, injecting a good epoxy adhesive and letting the crack spring back relaxed again. Good enough, or something better?
