The answer to the cost of a stone walkway near you is that it can vary quite a bit depending on several factors. In general, a professionally installed stone walkway can range anywhere from $10 to $50 per square foot, with the average being around $20-$30 per square foot.
The exact cost will depend on the type of stone used (e.g. flagstone, pavers, or natural stone), the complexity of the design, the size and shape of the walkway, site preparation required, and your location. Higher-end materials and custom designs will be on the upper end of that range, while simpler walkways with more basic stones may be on the lower end.
