SG Contracting, LLC

SG Contracting is a family-owned Waltham general contractor that says it's been in business since 2001, taking on remodeling, additions, decks, and other construction work. Houzz shows three portfolio projects under the company's name and lists a Massachusetts construction supervisor license, CSL-114317, for the business. Both public reviews on file are from 2025, and both come from subcontractors rather than homeowners: an electrical contractor (July 2025) says SG Contracting hired the company and never paid the invoice, adding that another reviewer described the same thing happening to them; a finish carpenter (May 2025) says Jon stopped picking up the phone after finishing the work, still owed money. The state's home improvement contractor registry lists SG Contracting's license, number 203160, as expired. Given the payment complaints, confirm the license is current and get a signed contract with a clear payment schedule and lien protection before any work begins — and ask directly how subcontractors on the job are being paid.
