About Cornerstone Master Builders
Cornerstone Masterbuilders LLC was formed in New York on May 31, 2026, filed personally by the owner or officer as the registered agent. The company is in the home improvement and remodeling category, a family-run business with over 22 years of experience, according to its website. It appears to be a local contractor serving a New Jersey area, based on the identity match reasoning. No annual report or EIN on file yet. We estimate revenue between $100K and $1M, with 1-5 core employees, and a brick-and-mortar footprint typical of a local contractor. The domain was registered on June 4, 2024, 726 days before the filing, suggesting the business was planned well in advance. The website is modern, built on WordPress, with HTTPS and structured data, though the copyright dates to 2016. The domain was registered through Dynadot. Notably, the owner filed personally rather than through a formation service, and the domain was registered over two years before the LLC was formed, indicating a pre-existing operation or long planning.
