Inquire about how they plan for edges, steps, borders, and transitions to existing surfaces.

Make sure the quote addresses curing time buffers, weather considerations, and any extra steps for uneven yards or existing slabs. A clear estimate helps prevent surprise change orders and ensures you get the finish you planned.
