If you have a basement or crawlspace in Bellmore, there’s a good chance you’ve already experienced the stress of groundwater, flooding, or excess moisture. That’s exactly where a sump pump comes in. These systems are designed to remove water that collects in a sump basin, typically installed at the lowest point of your foundation. When heavy rains or high water tables push moisture into your home, the pump kicks on and moves the water safely away from your structure.
We often install sump pumps in homes that have previously flooded or in new builds where moisture is a known concern. Even if you haven’t had a flood yet, if you see standing water, damp walls, or signs of mold in your basement, a sump pump can offer the protection you need before damage begins. It’s a proactive investment in the long-term safety of your foundation and air quality.
The most common reason we’re called out for sump pump repair is because the system wasn’t maintained properly. Sump pumps are machines, and like anything mechanical, they wear out over time. Debris can clog the intake screen, the float switch can stick, or the pump motor itself can burn out.
Power outages are another major cause of failure. During big storms, the same event that causes water to rise can also knock out your electricity. Without a backup system, the sump pump becomes useless when you need it most.
Another issue we see is improper installation. If the basin isn’t sized correctly, or if the discharge line isn’t pitched and routed right, you’ll get poor performance and frequent problems. That’s why we always make sure our installations follow best practices and local codes.
There are several signs you can watch for that may indicate your sump pump needs attention. If your basement smells musty or you see small puddles forming near the walls, the pump might not be running properly. Strange noises, like grinding or clunking, often mean the motor is wearing out or a part is loose.
You should also check if your sump pump is cycling too often or not at all. If the unit turns on and off constantly, it might be overwhelmed or miswired. If it doesn’t turn on during rainstorms, there could be a problem with the float switch or electrical connection.
In any of these cases, don’t wait until the next storm to find out if your system is working. A fast inspection can prevent a lot of stress and expense.
If your sump pump fails during a storm, your first priority should be damage control. Try to redirect water with towels or a wet vac, and elevate anything that could be damaged. Then give us a call. We offer emergency service and can often replace or repair your pump quickly.
We also recommend battery backups, water alarms, and regular maintenance to reduce the chance of failure. Our team can walk you through all your options and keep your system working when it matters most.
We uphold the highest standards in the industry, using top-tier tools and techniques to get the job done right. With extensive knowledge and years of experience, we’re ready to handle any sewer or drain crisis, ensuring swift, professional service you can trust.

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 Mapes2025-10-07Trustindex 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 Kim2025-10-06Trustindex 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 K2025-09-12Trustindex 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 Levow2025-08-29Trustindex 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 Burriesci2025-08-25Trustindex 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,
