Tools & Materials
In this video, This Old House landscape contractor Roger Cook shows how to rescue an old stone walkway.
1. Remove the old flagstones and set aside.
2. Lay out two garden hoses to represent the shape and position of the new 3-foot-wide walkway.
3. Use an edger to cut into the lawn along both hoses.
4. Move the hoses out of the way and use a shovel to excavate the walkway. Dig down at least 4 inches.
5. Install steel edging along each side of the excavated walkway. Hammer in steel stakes to hold the edging in place.
6. Install a 2×4 stretcher every 6 to 8 feet to hold edging at precisely 3 feet apart.
7. Line the bottom of the excavated walkway with landscape fabric.
8. Spread about 3 inches of pea stone over the landscape fabric. Remove the 2×4 stretchers.
9. Set a flagstone into the pea stone with a downward twisting motion. Then tap down the flagstone with a rubber mallet. Repeat to set the remaining flagstones.
