Evaluating the History of a Leaning Garage
Here are a couple tips for evaluating the history of a leaning garage.
Sometimes a four foot level is helpful in measuring the lean of a garage. Other times the lean is so obvious, no measurement is needed.
A close visual examination of the joints and separations between the corner trim boards and the siding will provide evidence for determining the history of the leaning. Unbroken paint spanning across the joint or rounded, painted edges at the separation indicate that the lean was present at the time of the last painting.
On the interior an examination of the plumb of the garage door track relative to the plumb of the door jamb will also provide evidence for determining the history of the leaning. A difference in the pitch or lean between the two evidences the amount of leaning that was present in the front wall of the garage when the door track was installed.
On the other hand, sharp-edged cracking and relatively clean fracture surfaces in the cracking or the separations in the trim indicate that the lean has progressed farther relatively recently.
