We spoke with several contractors before choosing Legacy Construction and are glad we did. Their communication was excellent, and they handled every detail of our project with care. They take pride in their work, and it shows in the final product.

It’s hard to find a trustworthy contractor these days, let alone one that cares about the all the details that can easily get lost in the grand scheme of the project. Legacy Construction threaded that needle, and many others, expertly. Looking forward to the next time we can work together.

Addition Building in Kennebunk

Your Home Has Run Out of Room You know exactly what the home needs.

Addition builder Kennebunk ME Legacy Construction
You have a home near Summer Street in Kennebunk that you have invested in and have no intention of leaving. The layout that worked five years ago does not work today. The addition you planned keeps slipping and another year passes without a build date.

You called a builder who came through and never followed up with a written scope. Another gave a price without any plan and could not explain how the new space would actually connect to what is already there.

Every month without more space costs your household:
  • We show up when we say we will, every single time

  • We build exactly what we planned and agreed on


  • Your property value stays lower than it should without the added square footage
  • The addition you put off this year will cost more to build next year


  • Every season you wait is a season your family goes without the space it needs

Stop putting the addition off. Call (207) 544-4607 for a free estimate today.
