(12) Is the floor at the doors cracked or loose, allowing the carpet to pull free of the strip or other fastenings?

(15) Is the padding on stairs flattened out too thin, or entirely worn away at the tread nosing?
(16) Are the fastening holes not deep enough, or the wood plugs defective, or of wrong type and size, or not properly spaced?
(17) Does the carpet require restretching because of improper installation, or is it tearing itself loose from the fastenings because of overstretching?
(18) If "Smoothedge" tackless strip has been used, has the proper "compression edge starting technique" been used, and are there enough strips used at all offsets, door jambs, sills, jobs, or other irregularities? Has the tackless strip been properly installed on stair treads and risers, as explained on pp. 141-145?
(19) Has the proper technique been used in capping the lowest step return in a stairway or landing? Are seams showing on treads or risers, or has the carpet been "bent" in the wrong direction, exposing the backing?
