Basement Underpinning
& Finishing


Structural depth,
finished for living.


The smartest way to add square footage is to reclaim the space you already own. We turn dark cellars into warm, high-ceiling living spaces.

At Amista Homes, we treat basements as structural engineering first. Whether you need structural underpinning to achieve a full 9-foot ceiling height, complete foundation waterproofing, or a legal secondary suite to generate rental income, we execute every phase to a custom-build standard.

Full-service, footings to final clean


  • Structural underpinning & foundation benching
  • Interior/exterior French drains & sump pumps
  • Legal basement apartment egress windows
  • Sub-floor thermal insulation systems
  • Mechanical layout routing & HVAC setups

Yes. We dig and pour concrete in alternating 3-foot pins supervised by a structural engineer to keep the building stable.
