“So grateful for such a quick response! We were on vacation and discovered our sump pump had died while we were away. Fortunately, we had no flooding, but it was just a matter of time since it had been steadily raining. One call to Andersen Plumbing and Mario arrived promptly. He assessed the situation and proceeded to install a new pump very rapidly and efficiently. I highly recommend Andersen Plumbing and will continue to call them for future needs. Thanks Mario!”

“I was able to get an appointment next day, when the weather was -20 out and they were swamped with work. They came out, diagnosed my problem, main line was clogged, and were able to bring the appropriate tools and fix the problem. They even showed me the block and removal using their drain camera. It’s nice to know good work by good people was done right the first time and a reasonable price. They are my go to plumber since moving into North Aurora almost two years ago and I would highly recommend them.”

“I had an excellent experience with this company! I wanted to replace our old water heater. Steve was great, came to my house same day for an estimate and got me on the schedule. They were very friendly and professional. He discussed the different options with me and what would meet our needs and budget best. I would highly recommend them!”

“I highly recommend Andersen Plumbing & Heating for your next plumbing job. The owner, Chad, took time out of his Saturday to come inspect an emergency plumbing issue we had called him about that day at our home in Naperville. He was extremely knowledgeable and helped us clearly understand the issue we were facing and the work that would need to be done.

Chad and his team arrived first thing Monday morning to fix the problem (6′ excavation and main water line pipe replacement and replaced our main shut-off valve) and finished this job in about 4 hours for a fair price. JC, a member of Chad’s team, performed the interior labor and was very helpful in explaining how I could repair the drywall that needed to be removed. Chad and JC also removed the large tree limbs that had to be removed for the excavator (typically not included in this kind of work).

Andersen Plumbing & Heating went above and beyond with their service, professionalism, and quality of work. We will be calling them for all of our future plumbing and heating needs and I recommend that you do the same!”

“Andersen Plumbing and Heating is a class act. We had an emergency situation in which our basement flooded during a heavy storm in the middle of the night. The morning after, a restoration crew came to clean up. It was then realized that the water was still coming in from an unknown source. My husband, from out of town, called Andersen Plumbing and Heating to figure out the problem.

Mario was very responsive. He and Chad were at our house within 45 minutes. They found the source and the problem (tree roots had grown into the joints of our sewer line) and were able to resolve it promptly. They were both very professional and answered all of my questions. The cost of the work was reasonable as well. In a situation that many could have and would have taken advantage of and charged exorbitantly, Andersen Plumbing and Heating was professional, trustworthy and provided quality work. After the service, we received a personal handwritten thank you note from Chad, the owner, and his wife accompanied by a discount for future services. We will definitely be using them for our future plumbing and heating needs. Great experience!”

“A seemingly simple DIY replacement of a leaking wax seal turned sour when I found the cast iron flange badly corroded on one side. As we live on a slab, and this was likely the original, I had no idea how it was attached when I couldn’t see any sort of screws. That was when I started calling around to various emergency plumbers…on a Saturday. And this is the only toilet in the house, mind you.

When I talked with Steve, he said he would be able to help me out but had two other stops, so it might be a bit. I said that’s fine and he said he would call in a while. After only about 45 mins he called to let us know he was on his way and would be about 30 mins. After showing up and taking a look at the situation, he had to make a trip back to the shop for the right parts which, luckily, he had. After that, it was smooth sailing. Got everything installed, toilet back in place, and we were good to go!”
