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.

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.

Bailey Kincaid

Jarod was very kind and professional, turns out my gas wasn't on and thats why my water heater wasn't working, which we figured out after he got here. The fee for just coming out here was quite steep, which might be something for the company to consider changing but otherwise good experience.

Leah Dittmer

Stacy Farina

We were so satisfied with the service that we signed up for the membership plan, and it has been totally worth it! Our water heater failed last night, and they came out first thing this morning to take care of it. Excellent service, very professional, prompt, and transparent about the (pretty reasonable) pricing.

Kenneth Freedman

This is my new plumbing professional after waiting 4 days for my regular plumber. I called them Friday afternoon around 12 to see if they could help with my tankless water heater issue. They showed up around 3:30 and had a replacement unit installed by 6 pm. Extremely reasonable and courteous employees. My unit was under MFG warranty which they processed for me even though it was not purchased from them. I was so pleased I added their maintenance plan too for future service issues. We need to support this professional service company.
