What procedure should be used to install a flagstone patio?

• A. Start in the middle and work toward edges
• B. Start at the edges and work toward the middle
• C. Start at one end and work towards other end
• D. Start at the high point and work toward the low point

Answer: (B)

Placing flagstone from the outer edges inward is about controlling the patio’s boundary and maintaining true, even edges. When you start at the edges, you establish a solid, square outline first, which makes it much easier to fit the interior stones to that boundary. This approach helps you keep consistent joints and avoid gaps or irregular borders as you work toward the center.

Starting in the middle risks misaligning the outer edges because you have to squeeze or trim pieces to fit the boundary later, which can lead to wobbly edges or uneven margins. The idea of starting at the high point versus the low point isn’t about the order of placing stones; it’s more about achieving the correct slope for drainage. Similarly, moving from one end to the other can work, but it offers less control over the outer boundary, which is why beginning at the edges is preferred.
