We are a small LLC company that manufactures steel buildings. We have written contracts for our buildings sales. We manufactured and installed a 30’x44’ building in Derry NH for a customer and it has been completed for a around 3 months now. The customer does not want to pay the balance on the building to us. The building was completed and signed off on the invoice by the customer and the building also passed inspection. The customer just refuses to pay the balance. We need to get our balance in full. How do we proceed with a lien on his home? Thank you
