Damaged stairs, rotting frames, or unstable rails don’t fix themselves — but we do. At Alliance Deck Builders of Maryland, we handle repairs quickly and safely so you can get back to enjoying your space. Don’t wait for small problems to become big ones. Our crew is local, licensed, and ready to get the job done right.

Ledger board failures: Loose or improperly installed ledger boards are one of the most common causes of structural deck failure. We inspect and secure all connections to prevent collapse.
Rotted support posts: Moisture-damaged posts can weaken your entire structure. We replace rotted wood with pressure-treated materials built to last in Maryland’s humid climate.
Wobbly stairs and railings: Unstable stairs and loose handrails pose serious safety risks. Our team reinforces and reattaches these elements using code-compliant hardware.
Cracked or warped boards: Surface damage isn’t just cosmetic. Splitting and warping may signal deeper structural issues. We assess and replace affected boards with exact matches.
Weak or sinking footings: Shifting footings compromise the integrity of the entire deck. We relevel and reinforce foundations for long-term safety and support.
