How James Hardie fiber cement siding actually goes together

Every James Hardie fiber cement siding job is built in a specific order, and the layers you never see once the job is finished are what actually keep water out of the wall or roof. The diagram walks through it step by step.

How a Siding Wall Assembly Works

  1. Sheathing — the structural wall surface everything else attaches to
  2. Weather-resistive barrier — a wrapped membrane that stops bulk water while letting vapor escape
  3. Rainscreen gap — a drainage and drying space between the barrier and the siding
  4. Siding — the visible cladding, fastened over the furring strips
  5. Window flashing — tucked under the barrier above and lapped over the siding below, so water never gets behind it

About James Hardie fiber cement siding

Fiber cement is a mix of cement, sand and cellulose fiber pressed into planks, shingles and panels. It does not rot, insects do not eat it, it will not burn, and factory-applied finishes hold color far longer than site-painted wood. It is heavier and more exacting to install than vinyl, which is exactly why installation quality shows. The Back Cove home on this site was re-sided with a complete James Hardie package of wood-grain plank.

This page is part of our siding work, which lists typical price ranges and materials. Other related services: siding replacement, vinyl siding installation, cedar siding and shingles, roof replacement.

What the job involves

  • Walls are stripped, repaired and wrapped, with flashing at every opening and roof-to-wall joint.
  • Boards are cut with dust-controlled tools and fastened to the manufacturer's nailing schedule.
  • Required clearances are held above roofs, decks and grade so the ends never sit in water or snow.
  • Butt joints get flashing behind them, and cut ends are sealed or primed as the manufacturer specifies.
  • Trim, caulk lines and touch-up are finished so the pre-finished color stays uniform.

Signs it is time

  • You want the look of painted clapboard without the paint cycle
  • Wood siding keeps rotting at the bottom courses and around trim
  • The house sits in wind and salt exposure that punishes other materials
  • You want a non-combustible exterior

What affects the price

  • Product line and profile: lap plank, shingle, panel or board-and-batten
  • Pre-finished color versus site painting
  • Trim package and detailing
  • Tear-off, sheathing repair and house height
  • Number of windows, doors and corners to flash and trim

Every job is priced from a free on-site estimate, with a fixed-price written proposal before work starts.

James Hardie Fiber Cement Siding: Why It Holds Up Through a Maine Freeze-Thaw Cycle

Fiber cement is cement, sand, and cellulose fiber, cured under pressure and heat into a board that doesn't behave like wood or vinyl. It doesn't swell with humidity, doesn't contract sharply in the cold, and holds paint far longer than wood siding does. That dimensional stability is exactly what a Maine wall needs through a winter of freeze-thaw cycles and a summer of coastal humidity.

What Fiber Cement Is Made Of

Fiber cement board is manufactured, not milled — cement, ground sand, and cellulose fiber are mixed, formed into boards or shingles, then autoclaved (cured under heat and pressure) to reach its final strength. The result is a product that's rot-proof and won't feed termites or carpenter ants, two things Maine's older wood-sided housing stock deals with regularly.

Fiber Cement vs. Vinyl vs. Cedar in Freeze-Thaw

  • Fiber cement doesn't expand and contract the way vinyl does, so it doesn't need the same slip-joint clearances at trim and corners.
  • It doesn't absorb and release moisture the way cedar does, so it isn't prone to the cupping or splitting that can show up on wood siding after repeated freeze-thaw cycles.
  • It's heavier and more rigid than either alternative, which is part of why it needs to be blind-nailed (or face-nailed per the manufacturer's fastening schedule) into solid framing or sheathing rather than floated the way vinyl can be.

Installation Details That Matter

  • Factory edges are pre-sealed; any field cut exposes raw fiber cement that needs to be primed or sealed before it's installed, or it can wick moisture at that edge.
  • Manufacturer clearance requirements from grade, roofing, and decking keep the bottom edge of the siding from sitting in standing water or snow load.
  • Butt joints are caulked with a compatible sealant, not left to rely on the board alone to shed water at every seam.

    We hired Cardinal Exteriors to reside our house and install all new windows, and it was a terrific experience from start to finish! Bob was one of the very best contractors we've ever worked with (and we've worked with many over the years). He was extremely responsive, helpful, respectful of wishes and concerns, and never pressured us in any way.

    Bob @ Cardinal Exteriors replace 26 windows and resided our office building in Westbrook in 2025. Being in the construction business, we understand how proposals sometimes come with change orders and surprises if not outlined up front. Bob and his team finished our job on schedule and actually below budget.

    CARDINAL EXTERIORS re-shingled my roof. Bob Proved to be Knowledgeable and Trustworthy. He was responsive to my questions and took the time to explain the materials being used and the steps they were taking to weatherproof the roof of my home. The work crew was polite and they cleaned up the job site at the end of each work day.
