Project: Siding Professional Replacement Service

RH Renovation NYC completed a precision high-access exterior siding replacement and envelope restoration project featuring compromised siding removal, structural sheathing inspection, weather-resistive air/water barrier laydown, engineered high-wind panel installation, and custom trim flashing encapsulation for an elevated penthouse residence in The Bronx, NYC. Elevated structures such as penthouse residential levels face amplified environmental forces compared to standard ground-level cladding—including extreme wind-shear velocities, severe thermal expansion and contraction cycles, driving rain during seasonal nor’easters, and harsh direct UV radiation.

When legacy penthouse siding systems degrade, seam seals split, or mounting clips fail, wind-driven moisture penetrates behind the primary wall barrier. Trapped water quickly degrades underlying exterior sheathings, corrodes structural framing studs, stains interior finishes, and compromises the building’s overall insulation efficiency. Furthermore, executing high-elevation exterior renovations in dense urban environments requires rigorous site safety protocols to protect workers, building residents, and sidewalk pedestrian traffic. This project was engineered to execute a safe, seamless, and high-performance exterior wall transformation: dismantling damaged materials, re-establishing a tight weather-resistive envelope, and deploying premium, high-wind resistant siding engineered for long-term urban durability.

Comprehensive Scope of Work & Installation Methodology

To satisfy strict New York City Department of Buildings (DOB) code requirements and OSHA high-access safety mandates, our licensed and insured Bronx restoration crew executed a multi-phase technical installation protocol:

• High-Access Rigging & Demolition Safety Setup: Technicians established secure high-elevation staging, perimeter safety netting, and full-body harness tie-off systems. The legacy, deteriorated penthouse siding panels and corroded fasteners were systematically dismantled and lowered safely without risking debris fall onto lower-level structures or ground pathways.

• Substrate Inspection & Wall Sheathing Stabilization: Exposed exterior wall sheathings were thoroughly inspected for hidden moisture rot, delamination, or structural decay. Compromised substrate panels were replaced with structural CDX exterior-grade sheathing to create a flat, nail-tight fastening surface.

• Weather-Resistive Barrier & Flashing Tape Integration: The penthouse wall assembly was continuously wrapped with a high-performance, vapor-permeable weather-resistive barrier (WRB). All window/door perimeters, corners, and material transitions were sealed using heavy-duty flashing tape to prevent air infiltration and water intrusion.

• Precision Siding Panel Installation & Thermal Expansion Calibration: Premium heavy-gauge exterior siding panels were mounted using corrosion-resistant fasteners driven into structural wall studs. Panels were installed with precision-engineered overlapping tolerances to accommodate seasonal thermal expansion and contraction while providing exceptional wind-shear resistance against high-altitude gusts.

• Custom Corner Post, J-Channel & Trim Flashing Integration: Heavy-gauge aluminum drip caps and engineered vinyl trim accessories—including corner posts, J-channels, and soffit transitions—were fitted around penthouses, windows, and door frames to divert surface runoff cleanly away from critical wall intersections.

• Perimeter Polyurethane Sealing & Final Safety Audit: All trim interfaces, structural penetrations, and wall joints were sealed using UV-resistant, non-sag exterior polyurethane lap sealants. A multi-point quality control audit verified flush panel locking, wind-anchorage integrity, and complete weatherproofing before dismantling staging equipment.
