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.

Why Norwalk Homeowners Call Us for Leak Detection

When it comes to water leaks, guessing isn’t good enough. You need fast, accurate answers without tearing your house apart in the process. That’s exactly what we deliver.

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.
  • Licensed, Background-Checked Plumbers - You get trained pros you can trust in your home.
  • Non-Invasive Techniques - We locate leaks with precision, no unnecessary holes in your walls or floors.
  • Transparent Pricing - You’ll know the cost before we do the work. No hidden fees, ever.
  • Local Know-How - We know Norwalk’s plumbing systems and home styles, so we get in and out efficiently.

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.

DJ was great. He was very personable and knowledgeable. He explained everything that I needed done and gave me different options to choose from.

I called as I had an emergency leak in my bathroom. Water was leaking at a rapid rate and covering the bathroom floor. I was unable to cut off the water outside as the cutoff valve was too difficult for me to turn. I spoke with Sarah who was kind, compassionate and efficient. Anthony and another plumber came within 30 minutes and fixed the problem pronto. They also drained my hot water heater for me. They were polite, clean and efficient. They left no mess and were able to get the water cutoff working. It had calcified. They will be my plumbers for life!

Lynn Liverakos

Rick did a great job replacing all the old leaky pipes under my kitchen sink. He was very efficient and knowledgeable with a ton of background experience. He patiently explained the work to be done, and explained everything he did as he was working. So happy with the quality of the work and the level of customer service. I would absolutely recommend him to friends.

Bradley Marciniec

Great company that responds quickly! Our technician, Eric, was personable and professional. He had to dig to find our septic lid on a hot day and kept up his positive attitude. Pricing was fair and he worked quickly. We will recommend Benjamin Franklin Plumbing and Eric to all of our neighbors!

Shymia Arps

Great service by Gage. He explained what needed doing for the garbage disposal and got the job done. Price was okay. He even attempted to fix an issue with the shower tub leaking but I declined the estimate for now but will call back in the future for a fix on it. The scheduling is quick and easy with them. Thank you

Brian Ruffing

We found our hot water tank to be leaking and no hot water and we needed a replacement ASAP. Looked into a few companies in Medina and Benjamin Franklin seemed to have the best reviews and customer experience, so we gave them a call at noon on a Saturday. They were able to send out a tech, Mike P, same day and he came to our house at 5 pm. Explained Mike the situation of the tank and additionally a few other plumbing issues that we were experiencing. Mike was able to replace the hot water tank and haul out the old one in 3 hours, on the same evening! Would definitely recommend Mike P and Benjamin Franklin when you are in dire straits with a plumbing situation. Mike P also gave us some recommendations of other issues we have and general tips to keep our plumbing system and water tank cleaner and longer lasting. We will be reaching to BF and Mike for any future plumbing needs!!
