Rose Bernard

Red Bank, NJ

We had a plumbing emergency and found Mr. Rooter while frantically searching for a 24-hour plumber. We feel like we hit a gold mine. Not only did we get a timely response. Everyone at Mr. Rooter was friendly, professional, competent and went above and beyond. Our plumber, Phil, was extremely helpful and gave us tips we could use moving firwars. Not to mention, the cost was extremely reasonable.

Joseph Chis

Hillsborough, NJ

Had sewer water backup in toilet and tub. Received callback as promised and arrived early. The tech determined we needed the main line to be cleared. He quickly located the opening and had us cleared in minutes. Very happy with the service. I was not prepared for the fee but it was an emergency.

Christopher Cox

Little Silver Township

Plumber, Phil, came out on short notice on a Saturday night and fixed our issue quickly, professionally and courteously. I contacted a different, well known plumbing company right before Mr. Rooter. The receptionist was rude and they didn’t call me back to say they couldn’t make it until after Phil left! The Mr. Rooter receptionist was very nice and they called me back quickly. I’m glad they did.

I just wanted to say James did a great job at my house. Excellent service, professional and very nice. Thank you so much for helping me with my plumbing problem. Did wonderful job.

Rachel Turunen

Jackson Township

I was very happy that I went with Mr. Rooter’s. The service was very quick and up front. Jessie James was very helpful answering my questions and replacing my hot water heater. He was pleasurable to do business with. If another problem arises in my home, I will be using this company again.

William Holden

Brick Township, NJ

A thorough, professional, pleasant experience. I had a back-up in the 50 year-old pipes of my new home. I called Mr. Rooter to have them locate the blockage, snake the line, and then use their video snake to get a visual of the integrity of the pipes. I’m glad that I called and will use them again for future needs.

You get what you pay for. Edwin Robles of Central NJ educated me as a 1st time homebuyer on why and what he was repairing, prevention, PROMPT,(on a sunday at that!) clean, knowledgeable, super professional but DOWN TO EARTH and at a REASONABLE PRICE! Sewer pipes unclogged and main water line fixed. I was no longer crying once job was thoroughly executed. After all $#@* $tinks but somebody has to do it and I HIGHLY recommend him and this company for a job well done. THANK YOU VERY MUCH!!

Margie Rafferty-Criscione

Ocean Township

Absolutely lovely office staff! I always knew when the repair person was coming. Lorenzo our repair guy was awesome, I really don't think there is anything he can't do. He looks young, but don't let that fool you! So happy all the repairs are behind us. We really just did a one-stop shopping and decided to have everything we've put off fixed because it was such a tremendous experience!

Signs Of A Main Water Line Leak

  • Water bill increase

Your water bill should be in the same range as previous months' bills. If you're getting higher water bills and there's no increase in water usage in your home or a price hike at your water company, your main water line could be leaking. Call a nearby plumbing service to inspect your main water line and determine its condition. Professional plumbers run specialized cameras through the water line to locate the source of the leak for accurate water leak repair.

  • Discolored water

Have you opened a tap and you're getting discolored water? There's a good chance the main water line is broken and dirt is finding its way into the water. A major water line break can allow dirt, debris, and other contaminants to enter your water supply. Tap water should be clear and colorless. Any form of discoloration often points to an issue that needs to be resolved. Discolored water can also be caused by corroded pipes and water quality issues on the supplier's side. If your pipes are old, call in a plumbing repair service to inspect your plumbing and suggest whether you'll need whole-house repiping. You can also check with your neighbors to see if they are experiencing the same issue.

  • Puddles in the street

Have you noticed bubbling water in the street where the main water line enters your home, yet it hasn't rained in the recent past? This is a sign of a potential main water line leak. When the water line bursts underground, the escaping water will first saturate the surrounding soil next to the burst pipe, and it will eventually reach the surface. If the burst pipe remains unrepaired, the puddle will continue to grow and cause sinkholes. By the time you notice puddles of water on the street, the pipe has probably been leaking for a long time. That's why we recommend taking fast action to prevent further water waste and potential contamination.

  • Foundational problems

A main water line leak that has been going on for a long time can lead to cracks in the home foundation. The escaping water can erode the soil around your foundation and weaken the concrete, causing cracks or spalling of the foundation. If you've noticed cracks in your home's foundation, call Mr. Rooter Plumbing for leak detection and water leak repair. Water leaks occurring undeeath your home's foundation are difficult to detect because the pipes are out of sight, and accessing them can be a cumbersome task. Professional plumbers use advanced tools and trenchless techniques to access the pipes and make repairs without digging up your property.
