Before
and after
Story of one deck:
What started as a weathered, splintered eyesore became one of our proudest transformations. The original deck was uneven, unsafe, and barely usable. After listening to the homeowner’s vision, we designed a modern, low-maintenance composite deck with sleek railings and built-in lighting.
The result? A beautiful, functional outdoor space ready for summer BBQs and quiet mornings with coffee. It’s not just a new deck — it’s a whole new way to enjoy home.
