The Addition Builder Scarborough Homeowners Call When the Addition Has to Be Done Right the First Time

After 30-plus years and 250-plus projects in Southern Maine, the pattern is clear: additions built without a full written scope before the first wall opens become the projects that drag on. We write the scope first.

What We Bring to Every Addition Build

  • We build exactly what we planned and agreed on
  • We never leave a project unfinished or incomplete

Five black stars.

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 Scarborough

Your Home Cannot Keep Up With Your Life You know what the home needs to become.

Addition builder Scarborough ME Legacy Construction
You have a home along Route 1 and the addition has been on the plan for over a year. The layout no longer fits how your household runs. Every fall you revisit the plan and every spring another season goes by without a build start or a date on the calendar.

You called a contractor who walked through and went quiet. Another gave a number over the phone with no plan behind it and no follow-up that arrived with any written detail about what the addition would actually involve.

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.
