James Hardie Siding Replacement in Kenner, LA
Southern Home Improvement Center completed a targeted James Hardie® siding replacement on the left and rear elevations of a single-family home in Kenner, Louisiana. The project replaced deteriorated wood cladding, corrected selected wall-sheathing problems, installed CertaWrap® weather-resistive barrier, added Hardie® Plank Cedarmill lap siding and smooth fiber-cement trim, and finished the new work with Sherwin-Williams Latte SW 6108 exterior paint.
This page is a project case study, not a generic product overview. It shows why partial-elevation replacement can be appropriate, what must be inspected after old wood siding is removed, how trim and wall transitions affect the finished result, and which details Kenner homeowners should compare when requesting a fiber-cement siding proposal.
Old wood siding replaced with a complete fiber-cement wall finish
The visible siding was only one part of the work. Once the failing wood boards were removed, the affected elevations could be reviewed for sheathing condition, wall alignment, opening details, penetrations, and the transitions where new siding and trim would meet the existing home.
Why the siding was replaced on only two elevations
Partial-elevation siding replacement can be practical when damage is concentrated on specific walls and the remaining cladding is still serviceable. On this Kenner home, the left and rear elevations showed conditions that justified removal and replacement: wood boards had cupped, split, and absorbed moisture.
Visible wood deterioration
Cupping, splitting, open joints, softened boards, and repeated paint failure can indicate that wood cladding is no longer protecting the wall consistently.
Concentrated weather exposure
Rear and side walls can receive stronger wind-driven rain, reduced drying, roof runoff, splashback, or vegetation contact.
Need to inspect concealed conditions
Removing the cladding allows visible review of sheathing, wall lines, penetrations, opening details, and previous repairs.
Controlled project scope
When other walls remain serviceable, replacing the affected elevations can solve the active problem without automatically expanding the project.
The decision depends on the condition of the remaining siding, profile and finish compatibility, corners, flashing, trim, wall continuity, and whether deterioration extends beyond the visible area.
What SHIC completed on the Kenner home
Old wood cladding and debris
- Removed the existing wood siding from the included elevations
- Hauled away project debris
- Exposed the wall surface for visible review
- Identified areas requiring additional preparation
Selective re-sheathing and CertaWrap
- Replaced selected soft or unsuitable sheathing
- Improved the wall plane before new cladding
- Installed CertaWrap over the prepared elevations
- Coordinated openings and penetrations with the new finish
Hardie Plank Cedarmill lap siding
- Installed factory-primed horizontal fiber-cement siding
- Used Cedarmill texture for a traditional wood-grain appearance
- Maintained consistent courses and reveal
- Finished transitions to remaining exterior materials
Smooth trim, sealant, and paint
- Installed smooth fiber-cement trim at included corners and openings
- Completed compatible sealant details where required
- Applied the specified exterior coating system
- Finished the work in Sherwin-Williams Latte SW 6108
What removal revealed about the wall
A siding estimate made from the ground cannot confirm every concealed condition. Old boards may hide soft sheathing, uneven wall planes, previous patching, missing water-control details, damaged trim, or deterioration around penetrations. This project included selective re-sheathing where the exposed wall required correction.
CertaWrap and the water-control layer
The fiber-cement boards are the visible exterior finish, but they are not the only water-control component. The prepared elevations on this home received CertaWrap before the new siding and trim were installed.
The weather-resistive barrier must connect with the rest of the wall
- Openings and penetrations must integrate with compatible flashing
- Layers should direct incidental water downward and outward
- Roof-to-wall intersections and kick-out locations require special attention
- Existing materials must be evaluated where the new work stops
- Installation should follow current product instructions and code
House wrap is not a stand-alone leak repair
A weather-resistive barrier must be part of a coordinated wall assembly. Incorrect window flashing, roof-to-wall drainage, penetrations, trim joints, or transitions can still allow water to reach the wall.
Hardie Plank Cedarmill siding and smooth trim
The new wall finish combines a wood-grain lap texture with smoother trim details. That contrast keeps the main elevations traditional while giving corners, windows, doors, and other framed areas a cleaner edge.
Cedarmill lap siding
Cedarmill has an embossed wood-grain texture and horizontal lap profile. Course layout, reveal, joints, clearances, and fastening must follow the instructions for the exact product and climate zone.
Smooth fiber-cement trim
Trim width, thickness, joints, fastening, flashing relationship, and transitions should be listed in the proposal rather than described only as “trim included.”
Configuration-specific fastening
Fastener type, placement, spacing, substrate penetration, blind or face nailing, and high-wind requirements must match the exact assembly and applicable code.
Clearances and flashing
Required separation from roofs, grade, steps, hardscape, decks, gutters, and other horizontal surfaces helps the wall drain and dry.
HardieZone HZ10 and the Louisiana climate
James Hardie identifies HZ10® as the product line engineered for southern conditions that can include strong sun, humid heat, heavy rain, salty coastal air, and hurricane-force winds. For a Kenner project, the proposal should identify the exact siding and trim products and confirm that the applicable installation documents and wind requirements are being used.
Heat and ultraviolet exposure
Product selection, coating quality, color, wall design, and maintenance all affect long-term appearance.
Humidity and repeated wetting
The complete wall still requires clearances, flashing, drainage, finished edges, and maintained joints.
Wind-driven rain
Lap siding helps shed water, but performance depends on the complete assembly behind and around the boards.
High-wind attachment
Fastening depends on the exact product, substrate, building height, wall zone, exposure, design pressure, and applicable requirements.
Performance depends on product selection, wall substrate, fastening, flashing, trim, openings, roof-to-wall details, and installation in accordance with current requirements.
Latte SW 6108 exterior finish
The factory-primed siding and trim were site-painted in Sherwin-Williams Latte SW 6108. The warm neutral works with the existing white window frames, soffit, downspout, and other light exterior details.
Warm neutral appearance
Latte creates a softer transition between the new wall surfaces and the existing light trim.
Preparation still matters
Surface preparation, dry conditions, compatible coatings, cut-edge treatment, application rate, and cure time affect the completed finish.
Keep the paint information
Retain the manufacturer, product line, sheen, color code, and project documentation for future touch-ups or repainting.
Installation details homeowners should compare
A proposal that lists only “remove wood siding and install Hardie” does not define enough of the work.
Included elevations
Identify every wall, gable, return, porch section, chimney surface, and area included or excluded.
Removal and disposal
State which siding, trim, sheathing, wrap, fixtures, shutters, vents, and related materials will be removed.
Sheathing allowances
Define whether the quote includes no sheathing, a limited allowance, unit pricing, or specified replacement.
Weather barrier
Name the barrier and describe seams, transitions, openings, penetrations, and integration with the remaining wall.
Siding and trim products
List brand, line, texture, width, reveal, trim profile, thickness, finish type, and color.
Flashing and clearances
Define opening heads, roof-to-wall locations, decks, slabs, grade, fixtures, and other transitions.
Painting and sealant
Identify coating manufacturer, coats, color, caulk locations, cut-edge treatment, and exclusions.
Concealed damage
Explain how photographs, change orders, unit prices, approvals, and schedule changes will be handled.
What changed after the siding replacement
Hardie siding cost factors for a Kenner home
This project page does not publish a blanket square-foot price because cost is driven by more than the visible siding area. A smaller two-wall project with extensive sheathing and trim repairs can cost more per square foot than a larger straightforward wall.
Total siding area
Wall measurements, gables, returns, waste, layout, access, and separate work areas affect material and labor.
Demolition conditions
Existing materials, layers, fasteners, debris volume, access, and applicable lead-safe requirements affect removal.
Sheathing and framing repairs
Soft sheathing, previous leaks, irregular walls, damaged framing, and concealed repairs can change the project.
Openings and trim
Windows, doors, corners, vents, fixtures, pipes, meters, and roof-to-wall intersections add detail work.
Product and finish choices
Plank width, texture, trim size, factory finish or site paint, colors, coating system, and accessories affect pricing.
Height and access
Upper stories, tight property lines, landscaping, fences, patios, utilities, and staging limitations affect labor.
Cleaning and maintenance after installation
James Hardie recommends periodic cleaning with a low-pressure garden hose and a soft nonmetal brush. High-pressure washing can damage the painted surface or force water into joints and openings.
Use low pressure
Remove dirt, pollen, and ordinary buildup with gentle rinsing and a soft brush as needed.
Review transitions
Look for open sealant joints, impact damage, paint deterioration, loose accessories, or vegetation contact.
Keep clearances open
Avoid building soil, mulch, hardscape, stored materials, or vines against the lower siding edge.
Retain project records
Keep product information, paint specification, photographs, proposal, warranty documents, and care instructions together.
