Most residential basements (24x40 typical) excavate in 1-3 days depending on depth, soil, and access. Wet conditions or rock add time. We coordinate with your builder's footing schedule so the hole isn't sitting open.

Both. We have ongoing relationships with several CNY custom home builders and act as their go-to excavation sub. Homeowners hiring direct also welcome.

Disclosed up front if site conditions suggest it. Light rock breaks with the bucket. Hard ledge needs a hydraulic hammer or blasting sub. We quote the rock-handling rate separately so you know exactly what triggers it.

We prep the subgrade for foundation drain installation and place the stone bed. The drain pipe and waterproofing is typically the foundation sub's scope. We coordinate.

Yes. Tight-access mini excavators when needed. Tree protection, ground mats over existing turf, sequenced material staging. Common on additions to existing finished homes.
