Fiber Cement Siding Installation in Lincoln: What Quality Looks Like
James Hardie's substrate warranty is 30 years. The catch: the warranty is contingent on installation per Hardie's published instructions. We've seen Lincoln Hardie jobs that voided the warranty on day one — and the homeowner had no idea. Here's what a quality fiber cement install actually looks like, and what corners the cheap bids cut.
Before tear-off: the substrate decision
A real Hardie install starts with full tear-off down to the sheathing. "Re-siding over existing siding" is not a Hardie-approved install — and even where Hardie permits it, doing so means you can't inspect the substrate, can't replace the wrap, and can't renew the window flashing. We never recommend it.
What to check at tear-off
- OSB or plywood sheathing condition — replace any rotted sections with proper-thickness lumber.
- Window and door flashing — almost always undersized or missing on pre-1995 Lincoln homes.
- Existing house wrap — almost always failed or improperly lapped on older homes.
House wrap: do it once, do it right
New 6 mil house wrap with proper laps (top course over bottom course, like shingles), shingled into window flashing, and taped at all seams with appropriate tape. Mechanically fastened with cap nails or staples per wrap manufacturer spec.
Cheap Lincoln Hardie bids often skip wrap renewal or do it with cheap product and zero tape. That single shortcut is where most underperforming Hardie jobs trace their leaks back to.
Window flashing: the real quality test
Walk past any active Hardie install in Lincoln. If you can see proper window flashing — full sill flashing pan, butyl tape on the jambs, head flashing tucked under the wrap — that's a quality install. If the windows just have caulk around them, that crew is cutting corners.
Hardie publishes specific best-practice flashing assemblies. We follow them on every install.
Kick-out flashing
Where a roof terminates against a sidewall, kick-out flashing is required. Without it, water rolls off the roof and dumps directly behind the siding into the wall cavity. Most Lincoln homes built before 2000 do not have kick-out flashing. Most cheap Hardie bids don't add it. We always do.
Clearances: not optional
Hardie publishes minimum clearances:
- From grade: 6 inches
- From decks, paths, and driveways: 2 inches
- From roofing: 1–2 inches depending on roof type
Skipping these clearances voids the warranty. We see violations on roughly half the Hardie jobs we inspect from other contractors — usually planks installed all the way down to the deck or grade. If a Lincoln Hardie job doesn't show clear gaps at all the right places, it's not a Hardie-approved install.
Fasteners: spacing and depth
Hardie planks need to be face-nailed or blind-nailed at specified spacing — typically 16" on center for blind-nail and 24" for face-nail. Fastener heads must be flush, not over-driven. Over-driven nails crack the plank under the head and are the most common warranty issue.
A proper install crew uses pneumatic nailers calibrated for fiber cement, not standard framing nailers cranked up. Worth asking the crew about.
Trim, joints, and butt-joint detail
Hardie plank butt-joints should be either staggered (offset by at least 24") or aligned on a stud with proper joint flashing behind them. Caulked butt-joints are not a Hardie-approved detail — they look fine for a season and then crack open. Z-flashing or factory butt-joint flashing is the right way.
Caulk and paint touch-up
Final detail is exterior-grade urethane or Hardie-approved sealant on trim joints (not panel butt-joints), and color-matched paint touch-up on cut edges of pre-finished ColorPlus® planks.
Warranty registration
The Hardie 30-year substrate warranty needs to be registered. Most Lincoln homeowners don't know this and never check. We register it for you and provide the registration confirmation in your project closeout package.
What to ask a Lincoln Hardie installer
- Are you a Hardie Preferred Contractor or higher tier? (Ask for the certificate.)
- Will my install include full house wrap renewal?
- How will you handle window and door flashing?
- Will you install kick-out flashing where missing?
- How will butt-joints be detailed?
- Will you register my Hardie warranty?
If the installer can't answer all six clearly, get a second bid. The cost difference between a cheap Hardie install and a quality one is usually 10–15% — and it's the difference between a 30-year warranty and a wall that fails in 8 years.
