Most residential projects in Montgomery County range from $8,000 to $18,000 for a quality paver patio, $65,000 to $150,000 for an in-ground pool with surrounding hardscape, and $4,500 to $12,000 for a seasonal landscape installation. The biggest cost drivers in this county are soil preparation and drainage. Worsham series clay soil is common throughout the lower elevations of Whitpain, Worcester, and Horsham townships, and it requires additional gravel base depth and drainage aggregate before any hardscape goes down. Most Montgomery County townships also require permits for pools, fences over 6 feet, and structures over a certain footprint, adding $300 to $800 in permit fees. Your free consultation includes a site visit, soil observation, and a written scope with material options before any commitment.
