Project at a Glance
- Elevations: left and back
- Demo: removal and haul-off of old wood siding
- Wall repairs: selective re-sheathing, flashing updates at penetrations
- New cladding: Hardie Plank® lap siding and smooth trim
- Finish: factory-primed boards, site paint topcoat
Scope of Work — Removal, Re-Sheathing & CertaWrap®
We removed and hauled away the existing cladding and evaluated the framing. Several areas needed structural attention, so we re-sheathed exterior walls where the old sheathing was soft or out of plane. Once the wall lines were true, we prepared the home to receive James Hardie fiber-cement with integrated flashing at penetrations, window heads, and ledger areas.
Before installing the new boards, we wrapped the elevations with CertaWrap® house wrap to improve bulk-water management and air control. The system aligns with best practices for primed Hardie planks over house wrap in Kenner, helping the assembly dry properly after heavy rain. For step-by-step best practices around house wrap, flashing, and drainage, see Siding Guides — Installation & Performance and kick-out details at Kick-Out Flashing in Louisiana.
Materials & Profiles — Hardie Plank Cedarmill Lap + Smooth Trim
For cladding, we installed Hardie Cedarmill lap siding to deliver the natural look of woodgrain without the upkeep of real wood. The horizontal reveal matches surrounding elevations for a seamless street view. At the details, we furnished and installed Hardie smooth trim around windows and doors and at all outside corners. The clean trim lines frame the home and give a finished, carpenter-grade look.
