Norwalk may be home to landmarks like the Hargitt House Museum and the beautiful Norwalk Civic Center, but for homeowners here, it’s what’s happening inside the walls that often goes unnoticed…until there’s a problem. Hidden water leaks have a way of creeping in quietly and causing major headaches: warped floors, rising water bills, mysterious mold, or that dreaded musty smell you just can’t trace.

If you think something’s off but can’t quite put your finger on it, Benjamin Franklin Plumbing of Long Beach is here to help. We’ve worked in homes all across Norwalk, from charming older houses on Pioneer Blvd to newer builds near Bloomfield, and we know how to spot trouble before it turns costly. With expert tools and experienced technicians, we’ll find the source, fix it fast, and save you from chasing puddles or paying for damage that could’ve been prevented.

At Benjamin Franklin Plumbing of Long Beach, we bring the right mix of high-tech tools and hands-on experience to every Norwalk home we visit. Whether you’ve got a soft spot in your drywall, a spike in your water bill, or a gut feeling something just isn’t right, we’ll track it down and walk you through the fix.

Here’s why locals trust us:

  • Advanced Leak Detection Tools - From thermal imaging to acoustic sensors, we find leaks without the guesswork.

Leaks are stressful enough. Our job is to make everything after your call feel simple.

Signs You Might Have a Hidden Leak

Some leaks are loud and obvious, while others quietly cause damage behind the scenes until it’s too late. The tricky ones are often hidden behind walls, under floors, or beneath slabs, slowly wasting water and weakening your home over time.

Here are a few signs that a leak might be lurking out of sight:

  • Your water bill suddenly jumps but your usage hasn’t changed.
  • You hear water running even when everything’s turned off.
  • You notice musty odors or unexplained mold spots.
  • Walls, ceilings, or floors feel damp or are starting to warp or stain.
  • Warm spots on the floor might signal a hot water slab leak.
  • Cracks in your foundation or flooring that seem new or worsening.

If you’re seeing or sensing any of these signs, don’t ignore them. A small leak now can lead to thousands in damage later.

Our Leak Detection Process

Finding a leak shouldn’t feel like a demolition project and with us, it doesn’t. At Benjamin Franklin Plumbing of Long Beach, we use advanced, non-invasive technology to locate leaks with precision. No wild guesses, no tearing up floors just to “take a look.” Our process is designed to save you time, stress, and money, because knowing where the leak is matters just as much as fixing it.

Here’s how it works:

  1. Inspection & Listening - We start by asking the right questions and listening for common clues, including sounds, smells, and pressure drops.
  2. Moisture Mapping - Using moisture meters and thermal cameras, we detect abnormal heat or water patterns behind walls and under floors.
  3. Acoustic Leak Detection - Sensitive equipment helps us zero in on the exact spot where water is escaping, even through concrete.
  4. Clear Diagnosis & Repair Plan - Once we find it, we explain everything: what’s leaking, why it happened, and how we’ll fix it.

We believe in fixing problems at the root, not just patching them up. When we leave, your home will be dry, safe, and leak-free, just the way it should be.

Casey is a very polite young man. He did a great job. Only got a 4 star because we have more work to do. We will be in touch.

Nancy Neal

Jade came out on July 3rd because our water heater was leaking. Very professional and informative. We decided we wanted to replace the water heater and get a water softener installed. Sent a text to him Thursday night saying we changed our mind about the water softener. Jade arrived on Saturday and we told him we changed our mind again. No frustration from Jade. Just okay I got you. Even though he had to run back to the shop to get a softener. He was great during the whole installation and kept us up to date on the progress. Highly recommend Northern Ben Franklin, especially Jade.

Paige Hartmann

Chris was amazing coming out to Siesta Key at 6:30pm on July 4th to unclog a unit that I manage! He was thorough, professional and clean! Very happy with the result.

Kenneth Norwood

WOW! If there ever comes the time that you need professional plumbing repairs or plumbing service of any type, I would enthusiastically endorse Benjamin Franklin Plumbing. I have found plumbing issues are always emergencies, very seldom routine, and each and everytime I call Benjamin Franklin Plumbing and a live dispatch professional picks up my call, completes a triage of my issue and schedules right then a professional plumber to race to my home for repairs. They have super talented plumbers and Paul and Noah responded to this call for assistance and were fantastic. They figured out what my issue was, actually had the parts required on their truck to do the job and immediately went to work and repaired my issue! They cleaned up their work area and were very respectful to my wife! Please consider Benjamin Franklin Plumbers, especially Paul and Noah anytime you need this professional service. 5 star all across the job! Thank you!

Adam Geller

Had an emergency over a holiday weekend, and no other company was available or even answered their phone. From the first person I spoke to on the phone, everyone communicated very clearly and attempted to help me out. Steve M.came out and was outstanding. He quickly assessed the issue and then got me up and running again. Steve was smart, explained everything he was doing, and was also just an all around funny and nice guy!

Jason Wilford

Our water heater went up on July 3rd, and Patrick was out there that afternoon to assess and give us a game plan. He came out again the Saturday the 5th to install a new electric heater to replace the old propane one. Very helpful, courteous, answered some other questions we had, as we just moved in 6 weeks ago. Prompt, knowledgeable And didn't try to sell you anything you didn't need. I'd recommend Patrick and this company to my friends and family if they come across a similar situation.

Bill Sowell

On a recommendation from our builder, we started using Benjamin Franklin Plumbing and couldn’t be happier. Matt Thrift just replaced our 18-year old tankless hot water heater and was prompt, courteous and professional. They kept us informed throughout the entire process.
