About This Market

UPDATED APR 2026

Dover's general contracting market runs hot with steady residential renovation demand driven by the town's proximity to Portsmouth and strong local economy. You've got 383 licensed establishments statewide competing for work, but Dover's growing population and aging housing stock keeps projects flowing. Kitchen and bath remodels dominate, followed by additions as families expand rather than relocate. Coastal influence drives up material costs, and skilled labor shortage pushes wages higher than inland markets.

To work Dover, get your state license locked down first - that business and law exam trips up plenty of contractors. Bond requirements mean you need solid financials upfront. Local building department moves efficiently but stick to their inspection schedule or face delays. Spring brings the rush as homeowners emerge from winter planning mode. Build relationships with local suppliers early - delivery schedules get tight during peak season. Weather kills outdoor work November through March, so plan interior projects for winter months.
