Deck Stairs Repair and Replacement
Stairs take the most weather and the most wear of any part of a deck. When treads go soft or stringers start to rot at the bottom, we rebuild the stairs on a solid footing with treads, risers and handrails that match your deck.

How we approach deck stairs
The bottom of a stair is where water sits longest, so stringers often rot where they meet the ground or a concrete pad. Treads cup and split, nails pop, and handrails loosen. A stair that flexes or wobbles is one of the most common injury risks around a house.
We build new stairs on a concrete pad or footing so the stringers never touch soil, use pressure-treated stringers spaced for your tread material, and finish them in the same boards as the deck. Every stair gets a graspable handrail and guards where the code requires them, and riser lights if you want them.
Short stairs off a ground-level deck usually take a day or two. Long stairs from a second-story deck, especially with a landing, take longer and may need a permit along with the deck.
What the job includes
- Removal and haul-away of old stairs
- Concrete pad or footing at the base
- New pressure-treated stringers sized for the rise and run
- Treads and risers in wood, composite or PVC
- Code handrails and guards
- Optional riser and step lighting
