George, I just want you to know how much we absolutely love our new deck and fence❤️ I only wish we had hired you back when we did the other half during COVID — what a difference your work makes! You, Tim, and Matt went above and beyond, especially working through that insane 40-degree heat 🥵🔥☀️. Your dedication, care, idea’s and craftsmanship did not go unnoticed. Your work exceeded our expectations. Thank you for being part of making our home feel safer, more beautiful, and closer to complet
