Ciardi Plumbing & Heating is a locally owned, fully licensed plumbing and heating company serving Chelmsford and the greater Merrimack Valley. With 20+ years of hands-on experience, owner Mike Ciardi handles every job personally — from boiler replacements and water heater installs to drain clogs and pipe repairs.
When you call Ciardi, you’re not getting a call center or a rotating crew of subcontractors. You’re getting a licensed Massachusetts plumber who takes pride in his work and stands behind every job.
From emergency boiler repairs to full pipe replacements, here’s what we handle.
Installation, repair, and maintenance of forced hot water boiler systems designed for efficiency, comfort, and long-term performance in both residential and commercial properties.

Traditional tank water heaters and tankless systems — we install, repair, and replace both. If you’re thinking about going tankless for better efficiency and endless hot water, we’ll walk you through the options honestly.

Slow drains, full clogs, and sewer line issues. We use drain camera inspections to find the problem before we fix it — so you’re not paying to guess. We also handle sewer line replacement when it’s needed.

Hidden leaks cause serious damage fast. Ciardi offers leak detection, slab leak repair, pipe repair, and full pipe replacement for both residential and commercial properties in Chelmsford and surrounding towns.

Dripping faucets, running toilets, cracked sinks, and shower plumbing — we handle all fixture repairs and replacements. Fast turnaround, clean work, and no mess left behind.

Proper gas piping is non-negotiable. Ciardi installs and inspects gas lines to code, and also handles outdoor hose bib repairs and replacements for seasonal prep.

There are plenty of plumbers to call. Here’s what makes the difference when you call Ciardi: you get the owner on the job, clear pricing before work starts, and workmanship that holds up.
