Gentilly 70122, LA
In Gentilly 70122, one hard rain off the lakefront and a weak exterior shows fast—swollen trim, peeling paint, and moisture sneaking behind old lap boards. New Orleans Pinnacle Siding Contractors installs James Hardie® fiber cement siding to help Gentilly homes stay tighter, drier, and better protected through hurricane season.
Gentilly 70122 sits close to Lake Pontchartrain, and neighborhoods like Gentilly Terrace and Pontchartrain Park see wind-driven rain, high humidity, and intense UV that can punish older wood siding and builder-grade panels. Our James Hardie Board siding installation in Gentilly focuses on moisture management first—because in New Orleans, the real damage often starts behind the wall. New Orleans Pinnacle Siding Contractors evaluates wall assembly conditions (sheathing integrity, existing housewrap, and window/door interfaces) before any fiber cement goes up.
For every HardiePlank® lap siding install and HardieShingle® or HardiePanel® application, we follow James Hardie Best Practices and align to ICC-ES evaluation guidance for fiber cement cladding. We layout courses with a story pole, maintain straight reveals, and install over a properly integrated WRB (Tyvek® HomeWrap® or equivalent) with flashing tape like Grace Vycor®. To handle Gentilly’s frequent gusts, we use corrosion-resistant fasteners (hot-dip galvanized or stainless steel where appropriate), hit studs consistently, and use coil stock and a metal brake for crisp drip caps, head flashing, and kick-out flashing at roof-to-wall transitions.
Cutting and fastening are done the right way for fiber cement: score-and-snap where possible, or a Makita® fiber-cement saw with a dust-reducing blade and HEPA extraction to control silica dust in line with OSHA standards. Joints are treated with manufacturer-approved methods—proper caulking at trim interfaces, flashing behind butt joints, and James Hardie ColorPlus® touch-up procedures when specified. We also protect vulnerable details—band boards, soffit intersections, and penetrations—using PVC trim or primed HardieTrim®, back-priming where required, and sealing end cuts to reduce moisture absorption.
Gentilly homeowners choose Hardie for results they can see: tighter wall lines, fewer paint failures, and a more “solid” exterior feel compared to aging wood or patchwork repairs. We help select profiles and colors that match local architecture—from the mid-century lines common near UNO and Dillard University to classic New Orleans porch details in Gentilly Terrace—while building to the performance expectations of James Hardie’s product warranty and our workmanship guarantee. The outcome is a cleaner façade, better resistance to rot and termites, and a siding system engineered for New Orleans weather cycles.
A homeowner in Gentilly Terrace (70122) near Mirabeau Avenue called us after noticing bubbling paint and soft spots along the lower courses of their original wood lap siding, especially on the north-facing wall that stays damp after storms coming off Lake Pontchartrain. They had recently repaired a small roof leak, but the siding still showed staining around window heads and a musty smell near an exterior outlet. New Orleans Pinnacle Siding Contractors scheduled an on-site assessment and found failed caulk lines, inadequate head flashing above two windows, and moisture intrusion behind the siding at several butt joints. We recommended a full James Hardie Board siding installation using HardiePlank® lap siding with HardieTrim® around windows and doors. The scope included removing the existing cladding, replacing any compromised sheathing, installing a continuous WRB, and integrating flashing tape (Grace Vycor®) with properly formed aluminum head flashings and kick-out flashing where the roofline met the wall. Our crew established a level baseline, used a story pole to maintain consistent reveals, and fastened planks to studs with corrosion-resistant ring-shank nails per manufacturer requirements. Cuts were made with a Makita® fiber-cement saw and dust extraction, then end cuts were sealed as specified. We finished with ColorPlus® factory-finished boards for a low-maintenance exterior and ensured all penetrations (hose bib, electrical, and vents) were flashed and sealed to prevent future water paths. After installation, the homeowner immediately noticed a cleaner, straighter façade and improved comfort near the previously damp wall. Most importantly, the new flashing and WRB integration stopped recurring moisture issues around the windows—critical for Gentilly homes that take repeated wind-driven rain during summer squalls and hurricane season.
