Flush Plumbing & Heating is the kind of Chelmsford-area shop people call when a plumbing or heating problem cannot wait. The company says it is family-owned, has 12 years in business, serves Essex, Middlesex and Norfolk counties plus parts of New Hampshire, and handles residential and commercial work. Its Massachusetts plumber license 9631063-PL-C is registry-verified active.
The written customer history is unusually consistent: 70 Google ratings average five stars, with recent reviews describing shower and tub fixture replacement, tankless water-heater work, boiler installation, furnace repairs, emergency pipe work and heating-system service. Reviewers repeatedly mention prompt responses, clear explanations, tidy finishes and fair pricing. One February 2026 review describes a furnace diagnosed from a video, visited within 90 minutes and repaired within an hour; another recounts a same-day response to a heating emergency.
The service mix is broad but coherent: plumbing repairs, drains, fixtures, water heaters, sewer and sump-pump work, plus heating-system installation, repair, maintenance, ductwork, thermostats, zoning and emergency service. The company also advertises bathroom and kitchen remodeling plumbing, free estimates within 20 miles of Chelmsford, and 24/7 emergency coverage.
They look like a strong call for homeowners who want one contractor for recurring plumbing and HVAC needs, especially urgent repairs and water-heating or boiler work. Before booking, confirm the exact scope, warranty terms and estimate; the license is verified active, while the website’s “Fully Licensed” wording is self-reported.
