Lebanon, Hunterdon County
In-county HQ (Lebanon), 50+ years locally, BBB A+ since 2005, call first if you want gutters bundled with a roofing or siding job; less ideal if you want a gutter-only specialist. Credential verified against the state registry, date shown.
Belvidere, Warren County
Deepest genuine review base found in this category (115 reviews at 4.9 on Birdeye, 4.9 on HomeAdvisor) and explicit Hunterdon town coverage from an adjacent-county specialist, verify the exact license number directly given the source inconsistency. Credential verified against the state registry, date shown.
Pennington, Mercer County
Longest track record found (founded 1988) among firms with genuine Hunterdon coverage, from an adjacent county, good second call for pure gutter work, but ask for local references since online review volume is thin. Credential verified against the state registry, date shown.

Registry status comes straight from the state's verification system on the date shown, and you can rerun any number there yourself in about two minutes. Review scores are what the named platforms report and we have not audited them. BBB grades as of July 2026. "Based in" is the registered address city, which sometimes differs from where a company says it operates. An active registration is the floor, not an endorsement; the picks we'd call first are above.
Gutters are cheap until the water goes where it wants. Then they're a foundation problem. We checked what's checkable on every gutter contractor we could find serving the county. Every fact on this page names its source and the date we checked.
We pull credentials from the official registries ourselves and print the date next to every status, gutter installers in NJ fall under the Home Improvement Contractor (HIC) registration, administered by the NJ Division of Consumer Affairs. It's a registration rather than an exam-based trade license, it requires proof of at least $500,000 in general liability insurance and renews every two years; it does not test technical competency. Verify any contractor's HIC number for free at njconsumeraffairs.gov/hec/Pages/verification.aspx or newjersey.mylicense.com/verification.. Picks are editorial judgment on the checkable record: years in the trade, complaint patterns, review consistency, real presence in the county. When a pick has a weak spot, we print it. Here are the full rules.
Seamless aluminum gutters installed run roughly $8-16 per linear foot in New Jersey as of 2026; a typical single-family home with about 160 linear feet of gutter costs $1,400-3,200 total. Copper runs far higher, $25-40 per linear foot. Sources: R&E Roofing NJ gutter cost guide (2026) and Build-Folio NJ gutter installation cost calculator (2026).

Not a trade license in the way electricians or plumbers need one. NJ requires a Home Improvement Contractor (HIC) registration for any home improvement job over $500, which covers gutters. It's a registration, not an exam-based license, the contractor has to prove they carry at least $500,000 in liability insurance and renew every two years. You can check any contractor's HIC number for free at njconsumeraffairs.gov/hec.
Seamless aluminum gutters installed generally run about $8-16 per linear foot in New Jersey; a typical single-family home with roughly 160 feet of gutter runs $1,400-3,200 total, per NJ gutter-cost guides published in 2026 (R&E Roofing, Build-Folio). Copper is much pricier at $25-40 per linear foot. Ask each quote to break out price per linear foot plus downspouts separately so you can actually compare bids.
They cut how often you need to clean gutters but don't eliminate maintenance, pine needles, seed pods, and ice still get through most screen types, and guards make it harder to spot a leak starting underneath. It's a legitimate add-on, but it's also the highest-margin upsell in this trade, so get the exact guard brand and type named on the estimate as a separate line item rather than folded into one bundled 'package' price.
