The Maryland Homeowner's Guide to James Hardie Fiber Cement Siding
What Hardie siding actually is, why it holds up in Anne Arundel County weather, the styles and colors available, and what to expect on installation day.
What is James Hardie siding?
James Hardie is the largest manufacturer of fiber cement siding in North America. Each plank is a blend of Portland cement, sand, cellulose fiber, and water — pressed, cured, and engineered to look like wood without any of the rot, warping, or insect damage that comes with it. For Maryland homes that swing from humid 95° summers to sub-freezing winters, that durability is the whole point.
Hardie's HardieZone system tailors product formulas to regional climate. Maryland falls into HZ5, the cold-and-wet zone, which means the boards we install in Crofton, Gambrills, and Severna Park are engineered for freeze-thaw cycles, wind-driven rain off the Chesapeake, and the temperature swings that crack lesser siding within a decade.
Five reasons Hardie outperforms vinyl
1. Fire resistance
Hardie board is non-combustible and certified as a noncombustible cladding. Vinyl melts at roughly 165°F — a backyard grill fire can warp a whole wall.
2. Storm and impact resistance
Rated to withstand winds up to 150 mph and shrug off hail and wind-blown debris that cracks vinyl panels. After a nor'easter, Hardie homes routinely come through untouched.
3. 30-year warranty
Hardie backs its planks with a 30-year non-prorated substrate warranty and a 15-year finish warranty on ColorPlus® Technology factory finishes.
4. Pest and rot proof
Termites, carpenter ants, and woodpeckers ignore fiber cement. There's no organic food for them, and moisture won't swell or rot the substrate.
5. Resale value
Remodeling Magazine's Cost vs. Value report consistently ranks fiber cement siding among the top exterior projects for return on investment — usually 75–88% recouped at sale.
6. The look of real wood
Deep wood-grain texture, true shadow lines, and crisp trim profiles. From the curb, most people can't tell HardiePlank from painted cedar.
The Hardie styles we install
HardiePlank® Lap Siding
The classic horizontal clapboard look. Available in Cedarmill (wood-grain) and Smooth textures. The most popular choice for Colonials and traditional Maryland homes.
HardieShingle® Siding
Cedar-shake appearance without the maintenance. Great for gable accents, dormers, and full Cape Cod or coastal-style elevations.
HardiePanel® Vertical Siding
Smooth or stucco-textured panels for modern farmhouse and contemporary designs. Pairs beautifully with batten strips for a board-and-batten accent wall.
HardieTrim® Boards
Matching trim for corners, windows, doors, and fascia. Replaces rot-prone wood trim so the whole exterior ages at the same rate.
ColorPlus® vs. primed-and-painted
Hardie offers two finishing paths. ColorPlus® Technology applies a multi-coat, baked-on factory finish in a controlled environment — far more uniform and UV-resistant than anything that can be sprayed on a jobsite. ColorPlus carries a 15-year finish warranty against fading, chipping, and cracking.
Primed boards ship ready for a field-applied 100% acrylic topcoat. That route lets you match an existing color or a custom HOA palette but typically needs repainting every 10–12 years. For most Crofton, Bowie, and Annapolis homeowners we recommend ColorPlus — the math works out cheaper over a 20-year horizon.
James Hardie pricing in Maryland
Installed pricing for a full Hardie re-side in Anne Arundel County typically runs $12 to $18 per square foot, all-in. A 2,200 sq ft two-story Colonial usually lands between $26,000 and $40,000 depending on trim detail, substrate condition, and how much wood rot turns up once the old siding is off.
Hardie costs roughly 30–50% more than mid-grade vinyl up front. The payoff is a 50+ year service life and a finish that still looks new in year 20. Most of our clients finance the project — see our financing options.
