What drives the price
- Material grade
- Fiber cement and cedar cost roughly 2× budget vinyl per square foot.
- Home size & stories
- More wall area and a second/third story (staging) raise both material and labor.
- Tear-off & disposal
- Removing old siding typically adds $1–3 / sq ft; layering over is rarely advisable.
- Trim, corners & details
- Window wraps, soffit/fascia, fancy gables and stone accents add labor.
- House wrap & insulation
- Moisture barrier and added insulation run roughly $0.50–1.50 / sq ft.
- Crew & certification
- Manufacturer-certified installers (e.g. James Hardie Elite Preferred) cost more but unlock the strongest warranties.
Common questions
How much does it cost to side a house in New Hampshire?
For a typical ~2,000 sq ft Southern NH home (roughly 1,500 sq ft of siding), budget about $7,000–$16,000 for vinyl and $14,000–$28,000 for James Hardie fiber cement, installed. Tear-off, trim work and added insulation move you up within (or above) those ranges.
Is James Hardie worth the extra cost over vinyl?
For many NH homeowners, yes: fiber cement resists rot, pests and fire, holds paint for years, and carries a 30-year non-prorated material warranty. The catch is installation — get it from a James Hardie–certified crew, since the warranty depends on correct fastening and clearances.
How much of a siding quote is labor?
Roughly 40–50% of a re-side is labor. That’s why crew experience and certification matter so much — the material is only as good as the install.
Should old siding be removed first?
Almost always. A proper tear-off lets the crew inspect and repair the sheathing, add a fresh moisture barrier, and avoid trapping problems behind new siding. It adds cost but protects the investment.
