Reinstalling Recovered Goods With a Short Roll and a Bad Overlap Seam
A property manager is reinstalling about 1,150 square feet of three-year-old carpet that was lifted for slab moisture mitigation: 40-ounce cut pile, 12 feet wide, originally installed stretch-in over 3/8-inch pad with 2-inch tackless strip. New pad and new tackless are being installed. The recovered goods cover a family room 14 feet 6 inches by 22 feet, a hallway 4 by 30 feet, and three bedrooms 12 by 12 feet. The previous installer had made a 2-inch overlap seam down the middle of the family room and never taped it, and had cut the carpet about an inch short at a 12-foot sliding glass door. There is 150 square feet of matching attic stock from the original dye lot. The manager wants to know whether the carpet can be saved, where the seams should go, and whether the material is sufficient.
1. Where would you place the seam in the 14-foot-6-inch family room, and what do you do with the existing 2-inch overlap seam?

The overlap seam comes out. A 2-inch untaped overlap is a double thickness of backing under the pile; it will never flatten, it has crushed the backing, and it is a trip-and-wear point. Cut it out and re-cut a clean edge - typically you lose 2 to 4 inches per side to crushed backing, which means the 12-foot piece is effectively about 11 feet 10 inches wide when it goes back down.
Seam placement in the family room:
- The room is 14 feet 6 inches wide and the goods are 12 feet, so a fill piece is unavoidable. After trimming the damaged edge, the fill is roughly 2 feet 10 inches to 3 feet wide.
- Run the seam parallel to the room's long dimension, so foot traffic crosses it rather than running along it.
- Push the seam to the least visible side: away from the entry sight line, away from the window wall where raking light exposes every seam, and out of the main path between the door and the kitchen.
- Keep the fill on the wall side, not the center of the room.
- Run every drop in the same pile direction. A reversed drop will shade differently and read as a stripe, which is worse than a seam.
Check the length of each recovered drop before cutting anything. The 1-inch trim at the slider may have shortened a drop below the 22-foot room length, and that changes where the seam must go.
2. Describe the stretch sequence, tackless setting, and how you finish the sliding door and the interior doorways.

Tackless. Set 2-inch strip with the bevel toward the wall, nailed in a zigzag at roughly 6-inch intervals. Leave a gap from the wall equal to the carpet thickness plus about 1/4 to 3/8 inch, per the manufacturer. Trim the pad to the strip and staple it, then tape the pad seams; pad must never lap over the strip or the tacks will not hold.
Sequence:
- Square the room from the longest wall and snap lines before installing any strip.
- Rough-stretch the length with the power stretcher, tail block against a solid wall base plate with a load-spreading block.
- Final-stretch the length, holding gains on the strip as you go.
- Stretch the width, then re-stretch the length once more; a second pass recovers what the first direction gave back.
- Trim, tuck, and roll the seams.
Stretch to the manufacturer's specification, typically about 1% elongation - tight as a drum, no cupping, no ripples ahead of the stretcher head.
Sliding door. Do not nail tackless in front of the track, and do not drive fasteners into the door track or its weep holes. Use a Z-bar or flat metal trim under the track, or turn and tack at the jambs, so the carpet is held without binding the door. If the old carpet was cut an inch short there, plan a new cut where the trim will cover it.
Interior doorways. Use a Z-bar or a bound edge and transition strip at each cased opening. Do not tack into a removable threshold; it will need to come up again.
3. Using linear-footage math, determine whether the recovered carpet plus attic stock is enough, and explain how you would reduce waste.

Area math is not enough on 12-foot goods. Work in drops.
Naive plan (all cut from 12-foot width):
| Area | Drop | Linear feet |
|---|---|---|
| Family room | 12 ft x 22 ft 6 in | 22.5 |
| Family room fill | 3 ft x 22 ft 6 in | 22.5 |
| Hallway | 4 ft x 30 ft 6 in | 30.5 |
| Bedrooms (3) | 12 ft x 12 ft 6 in each | 37.5 |
| Total | 113 |
113 linear feet x 12 feet is about 1,356 square feet. You have roughly 1,150 square feet recovered (less, after trimming the overlap and the short slider edge) plus 150 square feet of attic stock, about 1,300 square feet gross. Under the naive plan the job is short.
Waste reduction: the hallway drop is 4 feet wide out of 12, leaving an 8-foot-wide by 30-foot-6-inch remainder. The family room fill needs 3 feet by 22 feet 6 inches, which fits inside that remainder. Cutting the fill from the hallway remainder removes one 22.5-foot drop and brings the total to about 90.5 linear feet, roughly 1,086 square feet - inside the available material.
Then shop the drops: check the pile direction on the remainder before cutting the fill, and reserve the attic stock for the family room so the most visible seam stays within the original dye lot. Order additional goods only if a recovered drop comes up short after trimming.
