"I had a plumbing issue that I thought would turn into a major headache, but Mahon Plumbing made the whole process smooth and stress-free. They arrived on time, quickly diagnosed the problem, and had it fixed before I could even make a second cup of coffee. They were professional, knowledgeable, and even gave me a few tips to avoid future issues. The pricing was fair, and there were no surprises on the bill—just great service from start to finish. If you need a plumber who knows what they’re doing and won’t leave you with a mess, I highly recommend Mahon Plumbing. I’ll definitely call them again for any future plumbing needs!"

"I hired a plumber through HomeAdvisor using prepay but I would not recommend this service. The contractor left a leaky pipe that caused water coming up through carpet. I had to purchase a wet vacuum to dry out the carpet. I had to contact HomeAdvisor again and hired Dave the Plumber, LLC who had to redo the installation done previously. Dave the Plumber replaced all the piping and outside spigot because of a water leak the previous contractor left. Thank you Dave the Plumber for being a professional and a job well done."

"Toilet was backup and when flushing the water would come up higher and higher without going down. Dun Rite Drain Cleaning was the first to contact me. Sterling listen to what I stated the problem was, gave me a quote and inform me he could be at my home within an hour. Sterling was so professional, knowledgeable & friendly. Took care of me and made sure everything was good before leaving. I would highly recommend this company!"

"I've had to use them for a few things in the past couple months. The office staff and techs are always friendly. I recently had a larger section of pipes replaced. Two small drips had developed overnight in their work. I called them the next morning, and they got the tech back out that afternoon to fix it. They've been very responsive, and they make sure the job is done right!"

"Woke up this morning to my hvac leaking and contacted Markool. I have never used them before and was in a pinch. They fit me right in this morning and were out at my house within 2 hours. The tech stepped in the door and placed covers for his shoes so he did not track in any dirt which was impressive! The tech was very professional and super friendly. Problem was diagnosed and FIXED within an hour. The price was extremely reasonable to the point I was shocked in a good way (expecting a higher price). Anyways, I will most certainly be a returning customer. Thank you Markool Heating Cooling Plumbing."

"The technician arrived about 30 minutes late without calling to tell me; looked at the toilets and identified the problem fairly quickly. He was knowledgeable and considerate. The cost was a bit on the high side, but I never saw a plumbing problem that isn't resoved without a hefty fee! I recommend them again, though."

Toilets FAQs, answered by experts

The average cost to replace a toilet seal ring is around $50 to $200 if you hire a pro to do the job. If you do it yourself, you’ll only need to pay for the supplies. Wax rings alone cost anywhere from $5 to $25 at hardware stores and can save you a lot of money compared to having a professional installation. At the same time, a licensed plumber knows how to properly install your new wax ring to prevent premature issues down the line.

Replacing a toilet typically takes two to four hours. Several factors can impact this timeline, including the condition of the old toilet, flange, flooring, and pipes. If a professional discovers issues like a cracked flange, damaged flooring, leaky pipes, or a broken wax ring, the installation will take longer. Additionally, some toilets, such as wall-mounted or in-wall-tank models, are more complex to install and may require cutting into and repairing drywall, which adds to the project time. Given the weight of toilets and the importance of proper placement, it is often best to hire a professional for the job.

If you know the job is going to be extensive (and you don’t like surprises), hiring a Roto-Rooter specialist may make sense for you. You’ll know how much you’re going to pay right away.

That said, hiring the best plumber isn’t solely about price. If you've worked with a plumber you trust before or have a list of plumbing services you need tackled at your home, working with a plumber might be a better choice for you.

The main cause of bathroom leaks is seals and connectors that loosen or deteriorate over time, causing leaks to develop. It's important to stay on top of your bathroom materials, as toilets, showers, and sinks all have different lifespans. Toilets and faucets last between 10 and 15 years on average with regular maintenance, but different parts may have shorter lifespans than others.

To drain a broken toilet, place towels or plastic sheeting around the base in case of splashing or overflowing. Next, shut off the toilet’s water supply, usually via a valve on the wall behind the toilet. Begin flushing the handle to remove as much water as possible from the tank and the bowl. Don’t flush the toilet if it’s clogged, though. From there, use a large sponge to soak up any remaining water and wring it over a bucket.
