What Southern Maine Homeowners Say

What Legacy Construction Builds Across Southern Maine

Legacy Construction Service Area

Still Planning That Custom Home? You've pictured it for years.

Gray kitchen cabinets and appliances; beige countertops and floor.
Navy blue kitchen with white countertops and island, wooden floors, and woven pendant lights.

You drive through neighborhoods across Southern Maine watching new homes go up and additions take shape while your own plans stay in a folder. The custom home you sketched out last year is still just an idea. The 1,500 sq. ft. addition you need before next winter keeps slipping.

You called around already. One contractor never called back. Another gave a vague number and disappeared after the site visit.

Every season you wait is costing you more:
  • We show up when we say we will, every single time.

  • We build exactly what we planned and agreed on, with honest timelines.


  • Your property value stays flat while neighbors around you build.
  • You spend another season working around a home that doesn't fit


  • The project you want next year will cost more than it does today
