Siding
How to Choose a Siding Contractor in New Jersey
August 4, 2026 · 4 min read · Hammer Exteriors

The questions to ask, credentials to verify and red flags to avoid before you sign a contract.
Verify the Basics
Before anything else, confirm your contractor has:
- A New Jersey Home Improvement Contractor registration
- General liability and workers' compensation insurance
- Verifiable local reviews and references
- A written, itemized estimate and contract
Ask About Fiber Cement Experience
Ask how many Hardie projects they've completed, how they handle flashing and cut edges, and how they protect your landscaping during tear-off.
Red Flags
Be cautious of large cash-only deposits, high-pressure 'today only' pricing, or contractors who can't show past work.
Questions to Ask Every Contractor
Before signing, ask each contractor the same set of questions so you can compare answers side by side. A trustworthy company will answer clearly and put everything in writing.
- Are you licensed and insured in New Jersey?
- How long have you been installing fiber cement siding?
- Who will be on site, and who is my point of contact?
- What exactly is included in the price?
- What warranties cover the product and the workmanship?
Red Flags to Watch For
Be cautious of door-to-door storm chasers, high-pressure "today only" pricing, large cash deposits, and vague one-line quotes. Reviews, photos of real local projects, and manufacturer credentials tell you far more than a sales pitch.
Read customer reviews and look for patterns — how did the company handle communication, cleanup and any problems that came up?
Why Credentials Matter
Manufacturer certifications like GAF Certified Plus for roofing show a contractor has met standards for training, insurance and reputation. Combined with 20+ years of local experience, that's the kind of track record that protects your investment.
