For the general contractor or flooring professional, stair remodeling has historically been a bottleneck. Replacing a carpeted staircase with hardwood usually meant “full demolition.” You had to rip out the carpet, pry up the rough plywood treads, pull nails from the stringers, and potentially damage the drywall skirtboards in the process. It was a dusty, labor-intensive, multi-day ordeal.
Enter the 8071 Retro-Fit System. This product line was engineered specifically to convert the “Stair Remodel” from a demolition nightmare into a high-margin finish carpentry job.
The 8071 Anatomy
The Retro-Fit tread differs from our standard new-construction tread in profile and application.
- Body Thickness: It is thinner (typically 5/8″ or 3/4″) to minimize the rise height variance.
- Drop Nose: The key feature is the front nosing, which drops down 1-1/2 inches. This creates a rabbet (groove) behind the nose designed to hook over and conceal the existing rough framing.
The Installation Efficiency
Instead of removing the rough stair structure, the 8071 system encapsulates it.
- Prep: Remove carpet and staples.
- The Cut: The only modification required is cutting the “nose” off the existing plywood tread to create a flush vertical riser face.
- Install: The 8071 Riser is glued over the old riser, and the 8071 Tread is glued and nailed over the old tread.
The Margin Analysis
Let’s look at the economics of a standard 15-tread flight.
Scenario A: Full Replacement (New Construction Treads)
- Demolition: 1 Day (Labor + Disposal fees).
- Framing Prep: 0.5 Days (Fixing stringers damaged during demo).
- Installation: 1.5 Days.
- Total Time: 3 Days.
Scenario B: Retro-Fit System
- Prep: 2 Hours (Carpet removal + Nosing cut).
- Installation: 6 Hours.
- Total Time: 1 Day.
By utilizing the Retro-Fit system, a contractor can complete a job that effectively looks identical to a full replacement in one-third of the time. This drastically reduces labor costs and increases the “turnover” rate of jobs. Furthermore, the disruption to the homeowner is minimal—the stairs remain usable throughout the process, and dust is significantly reduced.
Technical Considerations
While the system is efficient, precision is key.
- Adhesive is Critical: Because you are gluing wood to wood, you must use a high-grade construction adhesive (PL Premium or similar) to bridge any gaps between the old rough tread and the new Retro tread. A void between the two will cause a squeak.
- Rise Variance: Contractors must check the height of the first and last step. Adding 5/8″ to the treads usually keeps the stair within the 3/8″ variance allowed by code, but this should always be verified before installation begins.
For the savvy contractor, the Retro-Fit tread is not just a product; it is a business model that scales.
