Frequently asked questions
Does New Hampshire require a GC license?
NH does not issue a state general-contractor license; towns handle permits. We pull and manage all required permits for your project.
Can you build smart-home features into a remodel?
Yes — pre-wiring during a remodel is the ideal, lowest-cost time to add automation.
How do you handle budgets?
We provide a detailed line-item proposal up front and track change orders transparently.
