"Ed and Jaime basically set us up in our new home! It would have been challenging to accommodate all the things Legacy did for us through another contractor. Their work is great but above all they are just solid reliable people you can trust. I appreciate Ed’s honesty and professionalism in ensuring all the moving pieces get done. I had the opportunity to hire few other contractors for separate needs and Legacy stood out in their commitment to do right by their customers and more importantly their own people as well. Overall just a great bunch of guys who love what they do and it shows in their performance."
