Working around an existing yard
Fences, gates, gardens, AC condensers, decks and sheds affect both the final layout and how the work can be built. A narrow gate may limit equipment size; a fence that must remain changes removal routes; an AC unit needs operating and service clearance. The access route should be discussed early, including how excavated material leaves and how concrete reaches the formed area.
Future structures
A planned hot tub, pergola, outdoor kitchen or shed should be identified before the patio is formed. Its footprint, loading, posts, utilities and service access may require coordination beyond an ordinary seating surface. Manufacturer information and applicable permit requirements should be checked for the actual installation.
Finish options and replacement
Broom, exposed aggregate and stamped finishes each change texture and maintenance. Samples help with appearance, but layout and drainage decisions should already be settled. For an existing patio, movement between slabs, water held near the house and widespread surface breakdown are more informative than one crack alone. Removal exposes the material below and creates an opportunity to correct the surface profile rather than covering the symptom.
