What a Strong Proposal Should Include
- Itemized estimate: A clear siding installation estimate lists siding, trim, soffit, labor, and removal separately. Our siding planning guide shows what to compare.
- Certification check: Confirm you are hiring a James Hardie certified contractor, since proper installation protects your warranty. Ask for current proof of that certification.
- Warranty terms: Request the product warranty in writing before you compare prices. All Hardie fiber cement carries a transferable 30-year non-prorated substrate warranty.
- Price anchor: Use a market benchmark when weighing bids. Fiber cement siding averages about $21,500 across New England, per Cost vs. Value data.
- Review record: Read verified homeowner reviews before you choose a contractor. Coastal holds a 4.8-star Google rating built on 950-plus verified reviews.
