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 Windham

Your Home Cannot Keep Pace With Your Family You know what the home needs to become.

Addition builder Windham ME Legacy Construction
You have been watching new builds go up along Roosevelt Trail knowing your own home needs the addition you have been planning for over a year. The layout that worked when you moved in does not work now. Another season passes and the footprint has not changed.

You called a builder who came by, seemed interested, and then went completely silent without sending a written scope or any kind of follow-up after the initial walkthrough ended.

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.
