Demar began as a small, family-owned company, providing plumbing services to the NYC area. Through the Founder’s hard work and commitment to providing the highest level of quality, our reputation flourished. We have grown dramatically since then, and have expanded our specialties to include HVAC/mechanical, fire protection, backflow prevention, and inspection modalities. There are currently two major divisions in the company: Service (encompassing all aspects of installation, repair, and maintenance) and New Construction (minor/major alterations up to high-rise buildings).
