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.
