What reviewers say

Delponte Plumbing & Heating

Delponte staff solve problems methodically, explain what they find, and leave no mess. Named technicians like Mason, Evan, Landon, Steve, and Derrick appear across reviews handling everything from spigot replacement to mystery leaks and boiler install, praised for patience and knowledge. A three-year customer calls them "professional, timely, fair, organized" and others note quick Monday-morning dispatch even after a holiday weekend. Monthly membership starts at $29.95; one reviewer remarked the emergency response on a heat wave holiday was "expensive but given the response... no one was complaining."

Service membership and proactive follow-up stand out. Charisse and Steve signed one customer into their HVAC maintenance program on the first call; Gabe, Dom, and Brian kept a boiler install "spotless throughout" and answered every question. Staff proactively fixed a secondary issue one household hadn't asked for, and another technician rang the doorbell because he'd been told the customer had questions. After-hours contacts get next-day 8 AM slots. The roster includes Mason Candler, Derrick Domina, Joel, Carson, and Landon, each cited for specific strengths.

SI Plumbing

Sam answers weekend and after-hours calls within hours and explains repair options clearly without surprise charges. His work spans emergency fixes, renovations, and heat systems, with thorough cleanup and follow-up that reviewers describe as honest and considerate throughout.

Every recent review rates him five stars. Customers consistently praise his same-day turnarounds, fair pricing held to quote, and willingness to go beyond the job scope. He serves Hartford, West Hartford, Avon, Bloomfield, Farmington, Glastonbury, New Britain, and Newington.

Which should you pick?

Pick Delponte Plumbing & Heating if

You want a company with bench depth so a leak or pipe job gets covered even if one tech is unavailable
The leak is intermittent or hard to trace and you want a team known for methodical diagnosis
You're open to a membership plan (from $29.95/month) for ongoing plumbing and HVAC coverage

Pick SI Plumbing if

You want the same known technician, Sam, handling the job start to finish
Firm, no-surprise pricing matters more to you than having a large backup team
Your property is in Sam's core coverage towns like West Hartford, Avon, Farmington, or Glastonbury

Verdict

Fit depends on whether you value team depth or a single trusted technician. Delponte Plumbing & Heating makes sense for leak detection jobs that might need a second set of eyes or off-hours coverage from a rotating crew, backed by a much larger review sample across 45+ years. SI Plumbing fits well if you want one plumber, Sam, who already knows the job and holds pricing to the quote, and your property sits in his core towns. Either way you're picking a highly rated outfit; the real decision is team backup versus single-tech consistency.
