If you know what to watch for, you can stop a leak before it causes thousands in damage. The most common early warning signs include unexplained spikes in your water bill, the sound of running water when no fixtures are on, low water pressure, moldy smells, damp drywall, and even unusually lush patches of grass in the yard. If you see any of these indicators, especially near fixtures like your wall hydrant or hose bib, it’s time to act quickly.
We also get a lot of calls from customers who notice water pooling near their outside faucet or sillcock, especially in spring. That can signal a split pipe behind the wall caused by winter freezing. These types of leaks are easy to miss at first, but if ignored, they can soak insulation, rot wood framing, and even flood the basement.
One of the biggest mistakes you can make is waiting too long to address a small leak. A pinhole leak under a sink or behind drywall might seem harmless at first, but over time it creates the perfect conditions for mold growth and structural rot. In extreme cases, slow leaks under the slab or inside the wall can damage flooring, ceilings, and even the home’s foundation.
It’s not just about the visible water. A persistent leak wastes gallons per day and forces your water heater and pressure systems to work overtime. That adds wear and tear across your entire plumbing system. We’ve seen it time and again. A $250 repair turns into a multi-thousand-dollar remediation job when someone delays.
Our leak detection process uses the best diagnostic tools available, paired with years of hands-on plumbing experience. Depending on the situation, we may use acoustic listening devices to pinpoint pipe noise, thermal imaging to detect temperature changes caused by escaping water, or video inspection cameras to see inside the pipes directly. For slab leaks or buried lines, we also offer pressure testing and tracer gas detection to isolate the problem without tearing up the entire floor or yard.
When a leak is behind your wall hydrant or hose bib, we carefully open up just the area we need, using moisture sensors and our inspection cameras to guide the process. That means faster diagnosis, smaller repairs, and less mess.
The most common leaks we deal with are behind toilets, under kitchen sinks, inside walls where hose bibs or sillcocks penetrate, and in the main service lines coming into the house. Each type requires a different approach. For example, a leaky outside faucet could be as simple as a worn washer or as serious as a cracked pipe behind brick or siding.
If it’s a leaking supply line, we’ll replace the damaged section with updated piping and secure fittings. For drainage issues, we may re-seal joints or replace traps. And if the leak is inside your wall or foundation, we make sure the repair is thorough and the surrounding materials are dried and safe before we close things back up.
The best way to avoid future leaks is to be proactive. We recommend annual inspections of all exposed plumbing, especially around older hose bibs, wall hydrants, and sillcocks. We can also install frost-proof outside faucets that are designed to protect against freeze damage. Inside the home, replacing worn supply lines, shutoff valves, and corroded fittings can head off issues before they begin.
If you’re noticing water where it shouldn’t be, or just want peace of mind, World Class Sewer and Drain is ready to help. Leak detection is one of our specialties, and we’ll make sure you’re not caught off guard by hidden damage.

They were immensely professional, timely, and knowledgeable. Upon arriving to our flooded basement- they immediately took charge and expertly navigated the situation/identified the cause. Communicating with them about times, $$$ and planning was efficient and effortless. We will absolutely never seek out any other company for our plumbing needs. Thanks guys!!!Posted on Bruce MapesTrustindex verifies that the original source of the review is Google. I had a bad backup of my kitchen and bathroom sink. I called Mike at World Class and he responded within hours and kept me informed when he was delayed at the prior job. It was a very difficult blockage due to my old galvanized pipes and a T-joint that joined the two. Mike spent almost 2 hours trying to get it unclogged. Most people would have given up, but he persisted and got it cleared. He lived-up to his “world-Class” name. Thanks Mike, I will be calling you again, and recommending you to anyone who asks.Posted on Joy KimTrustindex verifies that the original source of the review is Google.

Had a major issue with a clogged septic which created backflow and a mess into my basement. Mike and the team came within an hour and fixed everything. Amazing team, and explanation of what happened and what needed to be done to properly to prevent. I would recommend 100% and definitely utilize again as they were honest, reliable and professional.Posted on David KTrustindex verifies that the original source of the review is Google. I had a major issue in my basement with how the plumbing was set up. The previous owner had set up a horrible system. I had three other plumbers look at the issue and all of them misdiagnosed the issue. Mike and Mike recognized it right away and did fantastic work fixing it. Recently, they cleaned out a blockage in my septic tank pipe and replaced a toilet. Throughout the process they walked me through each step of what they were doing. When identifying issues they provided multiple solutions and recommendations. They are extremely professional, always respond quickly, and provide fantastic quality work. I can't recommend them enough.Posted on Richard LevowTrustindex verifies that the original source of the review is Google. On April 19th, 2025 the downstairs toilet in our home overflowed. As a result, the den level and basement required full remediation. This included removing all of the paneling in the den as well as sheetrock in the bathroom and basement. Once the carpeting was removed, we discovered that the floor tile was asbestos which required an additional protocol for removal. Fast forward to August 1st. The space was now roughly 70% done. The downstairs toilet was still not replaced. Someone flushed the upstairs toilet and water came gushing out of the toilet flange downstairs flooding the bathroom, part of the basement and part of the den. That required 4 days worth of work to be ripped out. In addition, I now had another claim with another deductible. As soon as this happened, I called World Class. Mike and Mike came out in the late afternoon and snaked the line from the outside of the house. They strongly recommended that I have them come back and inspect the sewer line with their camera. Mike returned the next week and we discovered that the sewer line to the main was separated. He explained to me that the situation that I had could be repaired with a high tech machine that they use for this type of problem. The machine coats the pipe with an epoxy resin which is more durable than the current pipe material. He assured me that it would resolve the issue. Mike, Mike, Hector and Gio came out that Friday and worked on the sewer line. They were at the house for roughly 10 hours. They worked in a highly professional manner and explained to me what they were doing as they proceeded. Needless to say having your house flood out twice is very stressful. Mike and Mike were excellent at calming my nerves. I highly recommend them should you ever have sewer or plumbing issues.Posted on Annamarie BurriesciTrustindex verifies that the original source of the review is Google. I had World Class Sewer & Drain come to my home in Oceanside, NY to install a new toilet and I couldn’t be happier with the service. The technician showed up on time, was professional, and made the whole process quick and stress-free. The installation was done perfectly and they left the bathroom spotless when they were finished. It’s rare to find a company that takes so much pride in their work and truly cares about their customers. If you need any plumbing work done — big or small — I highly recommend World Class Sewer & Drain. Absolutely five-star service!Posted on Google rating score: 5.0 of 5,
