Proof
Documented savings, not vibes
$6,200 saved
“The teardown found exclusions in our slab quote we’d never have caught. We went back to the contractor with the list and got them priced before signing.”
$14,700 saved
“Told us straight that our budget didn’t survive contact with reality — then showed us where to pull it back before we’d committed to anything.”
$9,800 saved
“Having someone one phone call away who’s actually run building projects changed how the trades dealt with us. Worth it for the variations alone.”
