Billy Calthcart, the plumber, worked tirelessly in fixing our ruptured gas line. When the city is involved in a damaged gas line, as was our case, there is a lot of red tape to go thorough in order to make sure the repairs meet whatever new regulations are in place. Billy made sure everything was done right. He dug a trench, replaced the gas pipe, found and corrected two leaks inside of the house, and replaced the shut off valves in our gas appliances. He did all of this in a professional and timely manner. I was impressed with his work ethic.
Description of Work: Billy Calthcart, the plumber, dug a long trench (18 inches deep), replaced the gas pipe, found and corrected two leaks inside of the house, and replaced the shut off valves in appliances.

Thank you for reviewing us on Angie's list. We appreciate all the positive feedback. Billy gets good reviews for the most part. He is an asset to the company and it sounds so good to hear people say that. He would not see this unless I sent it to him and I will. Again we are delighted you are a happy customer.

It was a waste of my time and money. The plumber refused to call the number and speak with the manufacturer tech support. He said the system worked fine and that my issue was related to low water pressure, even though it was well within the water heater specs. He made it very clear that he was only there to collect the service fee and that he had no desire to do actual work, he had an excuse for why everything worked the way it did. I had already contacted Rinnai (the manufacturer) and done a great deal of research and everything pointed to an issue with the unit, not with water pressure, etc... Finally, he said he would call and did so after he left. The extent of his call was to have the manufacturer customer service contact me. When they called, they simply asked what I needed and explained that I would still need a licensed professional call them. I contacted the home warranty company again, who sent out another contractor. The second company looked at a few things, attempted some basic troubleshooting and analysis (verified exactly what flowrates caused the unit to turn on and off, verified gas and water pressures/temps, etc...) and ultimately called the support line--5 minute later, they determined either a part or the whole unit needed replaced. Both companies were there for about 25 minutes, one spent the whole time arguing with me and trying to tell me it wasn't an issue and the other found a solution. I get these guys deal with people trying to tell them how to do their job all day long, but you still have to listen to your customer. IN this case, I'd done most of the legwork, they only needed to verify a few things. They were also supposed to come back out and never showed, they followed up at the very end of my appointment window (4 hours of missed work) saying they would call the manufacturer again.
Description of Work: Warranty service for my tankless water heater. It wouldn't activate at the right flowrate and the manufacturer required a plumber to call and perform some diagnosis/troubleshooting steps. I provided all of the information and asked that he called.

We are sorry you had a bad experience with our company. We would never want a customer feel like we were a waste of time and money. I am a little confused as to what happened this day so I will not defend or confirm anything except the way that you feel about us. Again very sorry our tech didn't take the time to listen in your opinion.

After telling me they were not going to address the soggy wall and completing the leak repair, they asked for a tip! They will end up making me pay another deductible to have someone else come fix the wall. I did not respond when the repair person asked for a tip.
Description of Work: J National was dispatched by my insurance company to fix a problem with a leak behind a soggy wall in my bathroom. They found the leak and repaired it, but chose to disregard the soggy wall. They told me to let it dry, put caulk in the holes, and paint over it.

Thank you for taking the time to review our company. I am a little confused as to the response that you would not hire us again based on the other statements you made about the response time and the honesty we gave you. I can see you not hiring us again for a/c but not for plumbing or electrical. Again thank you for the review and I hope you got a company better equipped to handle the problem you were having.

J National has never claimed any responsibility in this matter: I live in a three floor townhouse. The water heater is in the ceiling of the third floor. When J National turned on the water it took the technician to get to the second floor from the front of the property where the water turn off values are, before concern of the water was addressed, then the technician ran down and out the house to turn off the water. The sprinkler water line, which was broken and fully exposed, is a pressurized line which was pumping out water 40 gallons per minute (per code), and was coming out of the ceiling like a water fall for minutes after the water was finally turned off. The water flooded the third floor rooms, warped the ceiling in both rooms on that floor, it then worked its way through the carpet and floor boards to damage the ceiling in two additional rooms on the second floor. J Nation would not remove the soaked padding under the carpet, would not dry out the wood floor boards that were soaked from the damage. The damage was so extensive that J National stated that they had lost so much money on the project so far that they were not going to do anything more to fix the problem than they had done which amounted to getting the carpet dry (even thought the padding and the flooring was still wet), and take out a small area of sheet rock. They planned on using sealing primer on the remaining area to hide the stain damage then paint over it to avoid fixing the problem correctly. Joel, their supervisor during conversations about fixing the damage properly, threatened me by telling me how he could file complaints with the city stating that it was my error and through technical conversations with the city inspector make sure I was fined and sited. At this point I stopped calling J National and moved the claim onto my insurance company. The following are points to note in this damage: J National was at my house the first day for over 6 hoursJ National did not step on the pipe as noted but set the water heater on the pipe and crushed the PVC as noted by the technician, J National was at my house two additional times but never did any more repairs only ?inspections?. J National did minor damage repair on the first day but would not do the full damage repair to fix the damage their technician incurred to avoid future mold and mildew damage. J National used threats and intimidation to avoid fixing the problem correctly and ?avoid spending any more money on a financially losing project? ? their words. Everything that J National did do was recorded in my claim on file with my insurance company. The restoration company hired still had to do an additional $2,500 worth of repairs to fix the overall problem. I have contacted the City of Addison to confirm that the pipes in the attic were approved during the inspection phase of the construction and have the signed off approved permit application by the city. (J National stated that the work was done incorrectly when the house was built and was a city issue not their issue). J National has done everything they can do to not fix the problem and only touch up area?s to avoid any cost to them. J National did provide their insurance company but all claims were denied as J National claims no responsibility for the damages.
Description of Work: My water heater had begun to collect water in the collection pan, nothing serious, probably less than a glass but to avoid a major problem my warranty company subcontracted to J National for replacement of the water heater. Plumber came in, replaced the water heater and in the process crushed a main water line to my sprinkler system and when they finished the job and turned on the water it flooded the third floor of my house and parts of my second floor before the water was cut back off and the run off stopped. Plumber (subcontracted by One Guard - don't use them either) had a company come in and suck up the water and remove the wet insulation but did nothing more to fix the damages. Did not replace padding under the carpet, did not fix/replace damage dry wall, damaged crown molding, damages in other parts of the house from the water run off though the baseboards and duct system. I finally had to turn the claim over to my personal insurance company (I had to pay the deductible and increased insurance rates going forward due to the incident).

Was assigned this provider under my home warranty, so it was not our decision. They could not unclog it through the inside, so they needed to go through the roof. A second crew was dispatched for that phase, and when they showed up, they had very little instructions other than to make sure to collect the payment up front. While the problem was fixed to satisfaction, the process to define the solution felt sneaky, with a very aggressive tone. Also, they left quite a mess for us to clean up in the bathroom. I would never use them again.
Description of Work: Repaired a clogged sink due to accumulated gunk from A/C.

Dear Member, As you stated the problem was taken care of and we never heard anything about you not being a satisfied customer. I would not like to think that you would never give us another chance without at least giving us a chance to correct a problem. This is a good company that builds things to last, we put the team first and we serve people. I am sorry if your experience was not a pleasant one however we didn't know you felt that way.

There was some question early on about paying a higher service fee because we were a ways from their office but the Home Warranty company told them they would take care of any add-on fees and I didn't need to worry about those so they agreed to come out. They were here within 3-4 hours of making contact with them. They replaced the line from the attic to the refrigerator as we thought that was where the leak was. After Louis did that, we hooked up the refrigerator and realized that there was a leak coming from under the refrigerator. He called the home warranty company and told them. I thought someone would be upset they replaced the wall line since the leak was somewhere else but no one seemed concerned. The nice thing was the Home Warranty company called me a few minutes later and offered to send a refrigerator repairman out which was nice and saved me some time making a call and waiting on hold to talk to someone. Louis raised a concern as to whether the home warranty company should cover the repair. He thought it wasn't plumbed correctly but the home warranty company said they cover it. I was a little nervous when he did that but it worked out and he seemed very good after that. He gave me an estimate of $385 to replace the Pex line with copper but since I had recently paid someone to replumb the house with copper, I decided to ask them to come out and do it and they have agreed to do so.
Description of Work: I spent $59 on a service fee. We had a leak around our refrigerator and thought it was the plumbing line going to it.
