New Orleans Siding Installation

The Louisiana Fortify Homes Program (LFHP) is administered by the Louisiana Department of Insurance (LDI). It offers grants of up to $10,000 toward FORTIFIED Roof installations on a lottery basis. Registration windows open periodically. The grant focuses on the roof, not siding directly, but the construction practices that earn FORTIFIED Roof apply to walls as well, and homeowners pursuing the broader FORTIFIED Wall or Gold designation can bundle siding work with the roof grant project.

Yes. FORTIFIED is a national IBHS standard, so FORTIFIED Wall and Gold are available anywhere. Louisiana has the only state-funded grant program currently focused on FORTIFIED Roof, but the Wall and Gold construction practices can be pursued by any LA homeowner. We can install to FORTIFIED Wall spec when the homeowner is pursuing the formal IBHS designation, including third-party verification coordination.

New Orleans is in a heavy Formosan and native termite zone. Untreated wood-substrate siding, trim, and fascia are at constant risk. Hardie fiber cement is termite-inedible. LP SmartSide carries SmartGuard zinc-borate treatment for termite resistance. Solid wood siding (cypress, cedar) is generally not the right call in NOLA regardless of finish, because the substrate itself is vulnerable.

Hurricane wind, hail, and wind-driven debris are typically named perils on Louisiana homeowners policies. Adjusters routinely miss hidden vinyl bruising, wind-creased fiber cement, and back-side water intrusion. We document slope-by-slope and panel-by-panel and supplement when initial estimates miss damage. Hurricane Ida claims experience extends directly to siding scope.

It depends on the condition, the protection status of the home, and the homeowner's priorities. We have a real conversation before bidding. For homes in protected districts with original cypress weatherboard partly salvageable, restoration with selective replacement may be the right call. For homes outside historic districts or with extensively damaged original siding, wholesale Hardie HZ10 replacement with matched profiles can preserve the architectural character while delivering modern durability.

NOLA RH runs 80-90% year-round. Vapor-permeable WRBs let the wall cavity dry. Over-caulking on exterior siding traps moisture and accelerates substrate damage. Hardie fiber cement is dimensionally stable across humidity cycles; LP SmartSide's SmartGuard provides moisture resistance; solid wood is not the right call.

For Lake Pontchartrain-adjacent and downriver areas with chronic salt exposure, yes. Standard galvanized fasteners corrode within years in salt air. Hot-dip galvanized is acceptable for moderate exposure; stainless steel for severe exposure. NOLA proper away from the lake has moderate exposure and hot-dip galvanized is typically adequate.

For a typical 2,500 square foot NOLA home with no major sheathing or termite damage, 5 to 10 working days. Historic restoration work and FORTIFIED Wall pursuits run longer. Hurricane-season weather windows can add scheduling unpredictability — we plan around tropical-system tracks.

For inner-NOLA homes outside chronic salt exposure, premium-grade vinyl (0.046 inches or thicker, ASTM D3679 / VSI-certified) can work for budget-driven projects on simpler homes. For hurricane-exposed homes and homes with FORTIFIED Wall pursuit, we steer toward fiber cement or engineered wood. Standard-grade vinyl is not appropriate for NOLA hurricane-exposed applications regardless of price.

No. HZ5 is the cold-climate formulation engineered for zones 1-5 (think St. Louis or Chicago). NOLA sits in HZ10 territory — hot, humid, hurricane-exposed zones 6-10. Installing HZ5 in NOLA would be a climate mismatch — the formulation is not engineered for sustained heat, humidity, and hurricane exposure.
