The door that latched in May needs a shoulder by August
Expansive clay under this metro shrinks through a dry summer and takes water back after rain, and a door is where a homeowner first notices the ground moving.
The complaint arrives on schedule every year. A front door that closed easily in the spring wants a shoulder by late summer, or a patio slider drags at one end of its track and runs perfectly at the other.
A new door will not hold a slab still. What a good installation can do is tolerate the movement: an adjustable hinge system, a frame set with room to be shimmed again, a threshold that can be brought back into line without pulling the unit out.
Film the adjustment rather than the sale. Two minutes of a hinge being brought back into alignment in the second year answers the fear a North Texas homeowner already has, which no product feature does.
Show the tells too, because people can check them without you. A reveal that tapers toward the top of the jamb, a strike plate worn on one edge only, a slider that binds at one end of its travel and nowhere else.
Name the season you are looking at it in. The same door measured in February and in late August is two different doors, and a company that says so out loud gets believed about everything else it says.
