Deck Building & Carpentry
From ground-up deck construction to precision trim work inside your home, we bring structural know-how and a craftsman's eye to every carpentry project. Built to last through Maryland's four seasons.

Outdoor Living Spaces and Interior Woodwork You Can Count On
A well-built deck extends your living space into the backyard and adds real value to your home. But Maryland's humid summers, cold winters, and heavy rain mean that deck materials and construction methods matter. Leo General Contracting builds decks designed for the Montgomery County climate — properly graded, sealed, and fastened to stand up to years of weather without warping, splitting, or rot.
Inside the home, our finish carpentry services handle the woodwork details that elevate a room: crown molding, baseboards, window and door casings, wainscoting, and custom built-in shelving. Whether you're adding a new composite deck to your Potomac home or installing new trim throughout your Rockville rancher, we measure twice, cut precisely, and finish cleanly.

Carpentry Built for Maryland Weather
Weather-Resistant Materials
We use pressure-treated lumber, composite decking, and marine-grade fasteners selected specifically for Maryland's humid climate and freeze-thaw cycles.
Structural Integrity
Every deck we build meets or exceeds Montgomery County building codes. Proper footings, ledger board connections, and joist spacing are non-negotiable.
Custom Fit & Finish
Trim work and built-ins are cut to fit your specific spaces — not off-the-shelf approximations. Tight miters, flush joints, and smooth finishes on every piece.
