Petr was responsive to my inquiry via Yelp and Jason, the plumber who came out was such a nice guy and he did a great job with swapping out and re-sealing the pit lid. The first sump pump that was installed unfortunately had an issue with the lighted plug but they came back out to replace it so it's all good now. I highly recommend Jason to anyone looking for a plumber - he's really one of the nicest plumbers I've met and he'd clearly and patiently answer any questions you may have. Their quote was also competitive. I'd definitely be calling them in the future for my plumbing needs! P.S. if you're unable to reach them at their phone/office number, try messaging them via Yelp. I didn't really have much luck when calling their number but they're always responsive via Yelp/text and would call you back as well.

The plumber arrived late for appointment. He did not seem very knowledgeable. He kept muttering to…read morehimself and also kept repeating everything he said to me. I had a leaky shower faucet. He looked at the leak and went to Association office of my condo building to request a water shut off to change a cartridge. He was told the shut off would have to be scheduled. He came back to remove cover to see if I had a shut off by the cartridge. I did not. Even though I did not have a shut off he decided to remove the cartridge anyway, but was unable to turn it. Then he said if he was able to remove the cartridge everything would get quite wet because the water wasn't able to be shut off. Then he said he didn't want to get wet and would not try to remove the cartridge. He told me that he would have to return in 3-5 days when the water shut off to my tier could be scheduled. Since he could not remove the cartridge he decided that it was on too tight. He told me I would have to soak rags in vinegar and wrap them around the cartridge and keep rags wet until he returned. He told me if I didn't do this that he might have to go into the wall in the hallway to get to the cartridge. I told them that he would have to get permission from the Association to do something so drastic. The Association told him no. Then before he left he told me to keep the bathroom door closed and leave the ceiling fan on until he returned in 3-5 days. He closed the door. I told him that I had the fan on but wasn't sure it was even working. He did not check the fan and closed the door. When he left, he left muddy boot prints from my bathroom all the way to my front door. When I responded to the ad on Yelp the price to come out was quoted as $69.99 to come out. When he replied to my email he changed the price and said it would be $39.99, but before he left he changed the price again to $69.99. I am a disabled senior citizen dealing with a stranger in my unit and was afraid to question him. I notified his company about the mess he made and they said they had no one to clean it up except him. I told them I did not want him coming back at all because I didn't trust him. I also talked to Association office and we decided he was not competent and that he should not return. I hired a different plumber to come and look at the faucet. They came and found the bathroom door closed and asked me why it was closed. I told them that Preferred Plumbing closed the door. When the door was opened my entire bathroom was dripping water - from the ceiling, down the walls, dripping from the light fixtures and my medicine cabinet. All of the knobs on both my medicine cabinet and my vanity were corroded from the dripping water. The paint was pealing off some of the walls and bubbling up on others. The stain on my medicine cabinet was also peeling off. The floor was so wet I had to put towels down so this plumber could have access to the leaky faucet. Even though I had told Grant that I didn't believe the fan was working, he never checked it before he closed the door. The light fixture was blinking off and on. The new plumber told me that the water probably got into the walls and may have shorted out the wires. Even the floor tiles were coming up. The bathroom door was so distorted from the excessive water it had absorbed it had to be forced to open it all the way. I have been back and forth with Preferred Plumbing explaining the discrepancy in the pricing and the amount of damages Grant caused by closing the door, but they decided that Grant was not at fault. They also refused to adjust the pricing even though I sent them a copy of the email that Grant sent to me quoting the price as $39.99. When the new plumber came he had no problems removing the cartridge even though I had been unable to apply the vinegar soaked rags that Grant insisted were necessary. I would not recomend Grant or Preferred Plumbing to anyone. They changed the pricing and caused a lot of damage to my bathroom. They accepted no responsibility for the price changes Grant made and refused to take responsibility for any of the damages that Grant caused by closing the bathroom door without checking to see if the fan was working even though I told Grant that I did not believe it was working.

Grant is a professional who operates his business with integrity and a strong customer focus. He…read morehas helped me with several issues over the years, ranging from a leaky faucet to replacing a garbage disposal unit that was at the end of it's life. He's always punctual, works to understand exactly what the problem is I am having, and suggests several options for me to choose from on how to fix the problem at a fair price. I would strongly recommend his services in the Lombard area. With the recent boom in Private Equity-owned combination HVAC, Plumbing, and Electrical companies in the area, you'll not find a better run locally owned plumber.
