I dont know why anyone would rate less than 5 stars. Dermis has helped me on multiple occasions, including helping my elderly father, and my Mother-in-law. Pricing has always been fair. The work done well, quickly and with quality. Integrity is what comes to mind with Demmis. read more

We love this company! 4 years ago when we first moved to Lemont our water heaters went out. Demmis came right away and was able to replace them. Then shortly after our garbage disposal went out (the house has been a lemon) and they came right away and fixed that. Then our pipes clogged and again they came to the rescue. Now yesterday, Nicor decided to change out our meter and not tell us, and when they did this they didn't turn the gas back on. When we called Nicor they said we need to find a certified plumber to come out and turn it on. Demmis was there right away and got our gas back on. They have customers for life with us! Thank you so much for always being responsive and helpful! read more

Fantastic! Kitchen drain was backed up, we called and he was out in 20 minutes. Fixed the issue and even tightened a loose drain. Very professional and a very nice guy! Very reasonable as well. read more

I sent an email for a quote to have a faucet installed that I supplied and told them there was an ice line to deal with as well. They gave me a quote of 250$. I agreed and set up an appointment. My wife was home for it and I was at work when I get the call from my wife to talk to the plumber. He tells me it going to be 200$ more because he has to install a new valve because of the ice line. I told him no way that's way too much and he actually told me he has to shut off the water which takes 30 seconds. I argued the price down from 200 to 125$ because I just wanted it done. Do not use this company! read more

Dan, the person that I just talked to is so rude, arrogant and condescending. I noticed the attitude during my first call. After talking to my wife, we decided to give them a call back and confirm a schedule. During the second call, I tried to follow up and confirm about the schedule, cost, warranties, and some safety assurances and property protection. Instead of getting the confirmations, Dan asked me if I want the installation done or not. I asked for the owner, and he told me that he is the owner. I got Demmis Plumbing number from St. Scholastica's parish newsletter, as I am a parishioner. Parishioners - this plumbing company is not good. Arrogant and rude!! read more

I had a drain in the basement that started to leak. I called late in the day and scheduled a plumber early the next morning. He arrived on time, looked the problem over and explained what he needed to do. He then went to get parts (had some difficulty as local places didn't have what he needed, so he went further to get them), came back and did a super repair. The plumber was friendly and helpful about making sure that things were done right, even cleaned up after himself and the price was reasonable. I would call them again for help anytime! read more

Rude, brusque, seems pissed off that he's there and being PAID to do a job. I think the man is a bully. He charged me $1,090 to install an ejector pump. I think I may have been ripped off. I'll never hire him again. read more

Anyone who has dignity plz avoid this plumber or else you would be humiliated before your friends and family as this plumber talks in a very condescending manner. This plumber badly needs a lesson in manners. He charges arms and legs for his services . Work is highly unreliable . read more

if I could give zero stars I would. The woman who answers the phone is rude and condescending and seems uneducated. couldn't work a slurpie machine at 7-11. The plumber had to come twice to fix the problem, that's how he makes his money. if you want to be talked down to and ripped off, Demmis plumbing is right up your alley. read more

Hot water heater went out early in the morning. If anyone knows Chicago winters you know you can't be without hot water. Made a phone call to Demmis Plumbing and Sam was able to quote me a price immediately without having to get back to me. Not only that, but she got someone out same day within an hour or so. To top it off, the plumber was completely professional, replaced the old with the new very quickly and efficiently. He couldn't have been working for more than 45-60 minutes if that. Extremely impressed with overall service from beginning to end! Thank you! read more

Had one of those annoying little problems on a Saturday. Called in the morning, out the same afternoon! Throughout, Dan kept me up to date on his arrival, finished the work fast, and was on the spot with the quote he gave me on the phone. I'll definitely keep these guys handy on my contact list! Also, he showed up with a mask so great job being careful with your customers! Excellent customer service! read more

They did have masks on when they came. They were fast and efficient and very nice. I was very pleased with everything they repaired for me. Thank you. I would recommend this company read more

I had fantastic and fast service, quick to fix my leak, and a great job, will use Demmis Plumbing again .

I had Alex and his son here today to install a water softener. Fast and efficient work. He took time out of his scheduled work to fit me in, which I appreciate. They removed the old unit and placed it for trash pick-up and notable cleanup. They have earned my recommendation. read more

I found Demmis Plumbing through an add in my church bulletin. I called to schedule to get my kitchen sink unclogged (likely due to grease buildup). The woman I spoke with was very helpful and polite. I asked for an appointment on Tuesday, but had to switch it to this afternoon due to a work conflict. I asked if I could meet Alex at 5pm and told her that I thought that this would be a pipe replacement and that it might be a 2-4hr job. She didn't seem phased, and we scheduled the appointment, even though I thought we would need to do the work on another day. I was on time exactly at 5pm. The plumber was waiting. I told him that because the house is old (1954) I thought that the original drain pipe was likely corroded and blocking the flow with rust. I wanted to have the drain pipe replaced. He recommended rodding the pipe, but I thought that was a short-term fix and that I'd be doing this every year or two and thought that a new pipe was needed. I asked about the potential for a grease trap, and he said that is usually only for a commercial kitchen, and he thought he cost would be very high. He said ok decide: replace the pipe $460, or power auger $160. I asked for 2 minutes to text my wife when the last rodding was done. I suspected that it was less than 2 years. He would not wait. He said, decide now, or I'm leaving. So he left. I cannot comment on his workmanship, but I would not recommend him for his attitude. I left work early to meet him, and the problem is not solved. read more

I had a problem with my ejector pump. It took Demmis Plumbing three visits to properly diagnose and fix my problem. While sometimes it may take more than one visit to fix a plumbing problem, I thought three times was excessive. I had flooding twice in my crawl space after he came to fix the issue after the first and second attempted repairs. The problem finally seems to be fixed but since it took 3 visits on three separate days, I am giving Demmis Plumbing 2 stars. I do not recommend Demmis Plumbing. read more

I contacted them because his name was on a sticker on the current sump pump and water heater at my mother's older home. Woman who I spoke to when scheduling was great...promised he would call prior to arrival (asked for this because elderly bedridden mother in living room). He did not. When he arrived, had an attitude immediately just because I asked who he was and if he was owner or assistant. Would not introduce himself and seemed to be irritated that I hadn't let him in yet. His truck did not have any signage on it, that's why I asked. He had been to the house before for the same repair apparently a year ago. He ran some kind of blower through the kitchen sink pipes, so that the sump pump would stop sending water from laundry and sump pump through both kitchen sink drains. This did nothing to stop the problem. Also had slow flushing on a toilet that he looked at and attempted to "fix" but eventually, even though he admitted it was slow and looked clogged, said nothing was wrong. He stuck a wire hanger through the little water holes in toilet bowl and used some kind of plunger or auger but again said nothing was wrong. He charged me a lot of money for his time, and did not fix a thing. Yes, our pipes are old and there's a mix of old and new pipes in the basement, but everything was when he still not working right when he gave me the bill and he knew it. Water was coming up through the kitchen sink just as it was before. Yet he charged me...definitely do not recommend for poor attitude and quality of work. read more
