Frequently asked in New Hampshire
How do I evaluate a builder in New Hampshire?
Reference completed projects at your program size and quality level, walk two active job sites, confirm license and insurance, and review a full sample project file including budget history and change orders.
What contract type is best for a New Hampshire custom home?
Cost-plus with a guaranteed maximum price is the most common structure for well-defined custom work; fixed-price only works when drawings and specifications are fully resolved before signing.
What should the contract protect?
Scope, allowances, contingency ownership, change-order process, draw schedule, dispute resolution, warranty and closeout deliverables. Every allowance should reference a real specification, not a round number.
