The Importance of Proper Stair Construction
Second story deck stairs face unique challenges compared to ground-level steps. They must support significant weight loads, withstand lateral forces from wind and use, and remain stable over years of exposure to the elements. Poor construction can lead to:
Dangerous bouncing or swaying during use
Premature deterioration and structural failure
Code violations and liability issues
Costly repairs or complete reconstruction
That's why we employ proven techniques and robust structural designs for every project.
Mid-Span Support: The Foundation of Stability
One of the most effective ways to eliminate bounce and ensure long-term stability is incorporating mid-span support into your staircase design. This technique involves adding support posts and beams at intermediate points along the stair run, rather than relying solely on the connections at the top and bottom.
Project Showcase: Second Story Deck in Cary
Our first featured project demonstrates the power of mid-span support on a 9-foot high second story deck. The staircase spans nearly 16 feet from top to bottom, and without proper reinforcement, would be prone to significant flex and bounce.
"It passed Cary’s inspection...Ty must have impressed the inspectors. He certainly impressed me.""

We do what we say we do. That's integrity.
Landing Systems: Breaking Up Long Runs
For very tall second story decks, a single straight run of stairs isn't always the best solution. Landing systems break up the climb, provide rest points, and dramatically improve structural stability.
Upcoming Projects
Plans are in the works to build a multi-tier landing system for a local non-profit in Raleigh, NC. Their fire escape requires a 23-ft run to be broken up into safe spans of stair runs for a safe and reliable exit path.
⬆️ Top Landing
- •4x4 foot platform at the 12-foot height mark
- •Independent post and beam support system
- •90-degree turn configuration for space efficiency
- •Integrated with deck railing system for seamless appearance
↔️ Middle Landing
- •4x4 foot rest platform at the 5-foot height mark
- •Straight-through configuration for high urgency situations
- •Separate footing system for load distribution
✓ Structural Benefits
Engineering Details That Matter
At Pegasus Decking, we don't cut corners on the details that ensure long-term performance:
📐 Stringer Design
- ✓We use 2x12 minimum for all second story applications
- ✓Stringers are spaced no more than 16 inches on center
- ✓All stringers connect to structural framing, never just decking
Connection Hardware
- ✓Galvanized or stainless steel hardware exclusively
- ✓Through-bolts at all major connections, not just lag screws
- ✓Engineered brackets rated for dynamic loads
Foundation Work
- ✓All support posts bear on concrete footings
- ✓Footings extend below frost line (48 inches in our region)
- ✓Proper drainage designed around all footer locations
Material Selection
- ✓Pressure-treated lumber rated for ground contact
- ✓Sealed and stained all exposed end grain
- ✓Composite or PVC options for tread material where requested
Common Mistakes We Fix
We're often called to repair or replace staircases built by less experienced contractors. Common issues we encounter include:
Inadequate Stringers
Using 2x10s or wider spacing than recommended
Poor Connections
Relying on nails or screws instead of proper brackets and bolts
No Mid-Span Support
Long runs with no intermediate reinforcement
Insufficient Footings
Shallow or undersized concrete footings
Improper Attachment
Stairs connected only to deck boards or rim joists
