How we scored Dube's General Contracting LLC
Our 75/100 reflects four weighted pillars. See the full method for exact weights.
- Customer reputation — 82/100. Aggregated star rating across Google, BBB and Facebook, weighted by review volume on a logarithmic curve — so a handful of perfect reviews can’t outweigh a long, consistent track record, and an established firm isn’t buried by a brand-new one.
- Manufacturer credentials — 98/100. The heart of a siding rating: manufacturer installer programs (James Hardie Elite Preferred, CertainTeed, the Vinyl Siding Institute, LP SmartSide, Mastic/Alside), plus state licensing and liability insurance. Certified crews install to spec and unlock the strongest material warranties.
- Workmanship & warranty — 39/100. Years installing exterior cladding, the breadth of materials a crew works in (fiber cement, vinyl, cedar, engineered wood), and the strength of the written workmanship warranty behind the labor.
- Service & local fit — 74/100. How rooted the company is in Southern New Hampshire, whether financing is offered, and how easy it is to reach, schedule and get a written estimate from.
