Client Testimonials
Hear From Homeowners In Your Area
Watching our home transform through this addition was incredible. Legacy Construction communicated clearly, respected our space and vision, and delivered work that feels solid and intentional. You can tell they care about doing things the right way—and building work that lasts.
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.
We appreciated how collaborative Legacy Construction was throughout our project. They listened to our ideas, offered practical solutions, and kept everything on track. The finished work is beautiful and built to last.

Addition Building in Saco
You called a contractor who seemed serious and then never sent a written scope. Another quoted a number over the phone that was impossible to evaluate without any real assessment of the existing structure.
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
