About Keystone Hardscape & Design
From West Grove to All of Chester County
Alex founded Keystone Hardscape & Design Inc. in 2016 with a simple belief: outdoor spaces should be built right the first time. Growing up in southern Chester County, he saw too many contractors cutting corners — skipping proper base preparation, using subpar materials, and leaving homeowners with patios that cracked after the first winter.
Today, with over 8+ years in the building industry, Keystone has become Chester County's go-to hardscaping contractor. Alex still leads every crew, ensuring every project meets the same standard of excellence.
