American Builder Hardwood Floor

American Builder Hardwood Floor sands, refinishes, installs and repairs floors out of Quincy. Its own site dates the business to 2003 and advertises more than 20 years; the BBB profile, which carries an A+ letter grade without accreditation, puts it at 26 years and names Andy Nguyen as the sole proprietor. The stated service area runs from Quincy and Dorchester out to Cambridge, Newton, Hingham and Braintree. One report sits against that. In March 2025 Universal Hub described an insurer suing three floor companies — American Builder Hardwood Floor, Next Goal Corp. and Alpha Floor Sanding — blaming them for a fire the suit says caused at least $3.8 million in damage. That is one side of a civil case as a news site reported it, not a finding against anyone. Raise it directly when you call: ask what the company's answer to that suit is, how it handles finishes and dust control in an occupied house, and for two recent references you can phone before the sanders come out.
