They were efficient, knowledgeable and very reasonably priced. Would highly recommend and will call again for future plumbing projects.

Very professional reasonable priced would highly recommend courteous and on time knowledgeable

I could not recommend welter plumbing highly enough. One team came out yesterday to help with sewer issues and Ryan and Tony came out today to deal with some issues with a sink. Ryan and Tony are some of the kindest people I've met and thoroughly explained to me everything they were doing, and provided helpful tips on maintenance to prevent future issues. Pricing is reasonable and the service is absolutely exceptional. There's no plumber I trust more. read more

Welter has been unfailingly professional, whether they're fixing a drain or helping with the continued fallout from shoddy work by others on the basement plumbing. They're knowledgeable and respectful of the home every time they stop by. After an experience with self-styled sump pump repairmen who belong in small claims court, dealing with Welter has been a tremendous relief. I haven't found them to be condescending, rude or pushy at all. read more

Great company. Truly awesome. Another Plumber came out beforehand and told me they may have to break down the walls, and they came in and routed it out. Great company. God bless them. read more

I've been using Welter Plumbing for about 20-years and they never disappoint. I spoke with Dan Welter on the phone and explained my issue. He knew exactly what I was referring to. I was expecting some pipes needing replacement but he suggested it might be simpler than that. We scheduled an appointment for a few days later. Jesus and Tony arrived and reviewed the issue with me. They explained my options and what to expect. They were professional, polite, hard working, and nice guys. They fixed my issue quickly and made sure the repair was right before they left. I am happy to leave an updated review for them. read more

Came out last minute on a Saturday and fixed our leak quickly. Great honest guys who know what they're doing

Work was good and people are friendly. Price seemed high (over $500 to replace stems in 3 leaky faucets), but maybe that is what plumbers cost now. read more

My family has used Welter Plumbing since the 1970's. I have continued to use them when I started purchasing my homes. Trust and confidence are the two words that come to mind. They are on time and have a van full of supplies that I need and didn't know. read more

Extremely Knowledgeable and of the Highest Integrity. Rarely these days do you come across truly remarkable people in business who do the right thing for the customer, it is usually the opposite. When I talked to Dan last week, I was truly impressed. As a shade tree mechanic, I have fixed most things over the past 50 years. I had a leak in the shower that I tried to fix it and I could not stop the leak. I gave up and decided to call a professional to come fix it. After calling Welter Plumbing, Dan asked us to send a few photos of the problem. He called back a few minutes later and we talked briefly. He gave me fantastic advice over the phone. 15 minutes later, I fixed the leak. I am truly grateful for saving me hundreds of dollars on a service call and would highly encourage to reach out to Welter Plumbing for ALL your plumbing needs. read more

We had a leak in the ceiling of our basement bathroom. I called Dan at Welter plumbing who came out the same day to determine the issue. The next day Jesus and Tony arrived to find and fix the leak. Jesus identified and fixed the problem in less than one hour. Tony cleaned up the resulting mess. The area was spotless when they departed. What was a potentially awful experience was made easier by Welter. We have been customers for years and have never been displeased. I highly recommend Welter Plumbing. read more

Have used them quite a few times and have been very pleased. They are competent and great follow through. Each plumber has been a good communicator and did a thorough job each time. Use them with confidence. I used a few other plumbers and these folks are really the best. read more

Wish I know Welter plumbing earlier then we would not have to suffer the pipe freezing outside the garden and the nuisance of leaking j tubes under the sink. First, Dan is real good in assessing what we need to fix the problems. The crew arrived on time with all the first class materials and finished the job beautifully and professionally on time. Then they taught my hubby how to operate the valves and how to drain the pipe in winter to prevent frozen pipe in subzero temperature. The copper pipes are beautiful the valves are strong. The under the sink chrome j tubes is beautiful and they put an extra connection outside the wall then if it is clotted I can easier open it with my hand and take care of the blocked j tube without using toxic chemicals and equipments. Thank you very much for the job well done. You have an A team in your company. read more

I had to use them for my mothers leaking shower. They were very accommodating to the time frame that we had because she lives in a condo and the association would only allow the water to be shut off for 2 hours. They arrived on time, were very nice and professional. The only down side was the price which was $350 for about 30 minutes of work. In fairness I've never had to hire a plumber before so this may be an average price for the services the rendered. I would definitely hire them again. read more

What can I say about Welter Plumbing other than they are the best! Dylan and Reco came out and were kind, courteous, knowledgeable and so helpful. They listened to my problems and concerns and made very quick work of the problem. Welter Plumbing are incredible read more

They are awesome!! I had to use them 3 times over the course of 7 years. As a first-time home owner, I had a minor plumbing issue. They were honest (said they didn't want me to pay $$) and patiently walked me through on the phone so I could do it myself. The second time, they came to my house. They were professional and fairly priced. The third time was when I was selling my home. The inspector's report asked for a missing valve per code. The buyer wanted credit. I called Welter Plumbing and Eric explained to me that the valve is not necessary in our house (given the type of plumbing system we have) and not a violation of code. He sent me a letter/documentation to provide to the buyer the same day. It's been so wonderful to have discovered Welter Plumbing. I hope they cover Glenview too. read more

On Saturday morning , suddenly we had no 2nd floor hot water in master bath. We called our usual plumbing company , Welter, and amazingly , within 15 minutes , Dan Welter came out , followed the piping and was able to diagnose the problem and solve it within minutes. We have used them for years and they are great.. reliable , honest , competent , and responsive. Great company and we highly recommend them ! read more

This is the second time I've used Welter Plumbing and I must say that they are the best. They're super quick, nice, clean, and affordable. If you need any work done, don't hesitate to call them. You won't regret it. read more

I just need to let any potential plumbing customer know that Welter Plumbing is the best and most conscientious company you will find in the North Chicago/North shore area. They absolutely stand behind their work, and the work is excellent. Replacing fixtures, rodding, drain clearing, they are fast and efficient, and charge fairly based on their hourly rate. You won't find better. read more

Highly recommended! We had a sewer problem where they came out and rodded from our toilet to clear a soft blockage. Both Johan and Tony were professional, respectful, and responsive to working on this job. Definitely will be using Welter Plumbing Inc. / North Coast Sewer & Drainage, Inc. in the future. Thanks again and shot out to Johan and Tony on an awesome job! read more

Welter plumbing replaced our 27 year old 75 gallon water heater, replaced the main shut off valve for the house water supply, and installed a new non-freeze exterior spigot including running new copper water supply lines for it. The whole experience was excellent. The cost estimate was cheaper than the 2 of their local competitors who also have a great reputation. Welter did a great job, and I will definitely work with them again. Dan Welter, the estimator, and Jesus, the on site plumber, were both great. High quality guys that you can trust. read more

We had kind of an emergency with the sudden onset of a plugged sewer line. Probably my fault for not taking care of regular maintenance but, regardless, I called and they were able to send someone within a half hour. The line hadn't been rodded for several years but they were able to get the line open and flowing. Not an easy job but done as quickly and efficiently as possible. Needless to say, I was expecting the worst when the bill was totaled but discovered it was reasonable, especially given the short notice on the job. read more

Excellent service, quick response, very helpful information and transparency of costs (and nice people). Highly recommend this company for excellence in every respect! A pipe slowly leaking water coming from the city (that was behind paneling) in my basement has been repaired; a new Chicago Faucets faucet replaced the leaking, unrepairable one at my laundry tubs; replacement of all piping under my kitchen double sinks (loose connections, had leaked in the past). Also, one sink strainer basket was found to be leaking. Welter came out another day with the part in the finish I needed. Well worth the cost and peace of mind knowing Welter has taken care of all my plumbing issues. read more

Can't say enough about this team! We left a voice mail after hours and got a call the next morning at 6:40am. Thankfully they had a cancellation, arrived by 7:20 and we had a new pit pump and switch within an hour. Friendly, knowledgeable and so responsive. You guys always come through - thank you!! read more

Great job replacing the cartridge in my shower to rectify water temp change. Also ran to the store to get me a proper knob which was contributing to the problem. The other two companies I called were going to charge me extra to identify the type of faucet I had (because there was no inscription). The woman on the phone had me text a photo to one of the plumbers on staff. Total cost: $275. Smart company you can trust. Go with these folks. read more

Ladies don't call. Very condescending to women. We have used Welter for a number of projects in our home. They have typically done good work at a fair price. When I called to express concerns about work they were doing I was told I didn't know what I was talking about. I ended up hanging up because the gentleman was so rude. Doubt we'll use them until they realize women make up over 50% off the workforce and we pay the bills. read more

Frankly you need 6 stars for these folks. From the very helpful person on the phone to the service folks themselves. I couldn't have been happier. James was beyond what you could ask for, just the nicest person on top of taking care of our issue. Thank you for prompt (serviced next day) and excellent service. read more

My experience with Welter began with the fact that two people I work with independently recommended them. Next: When I called, I talked to a real human, as opposed to having to wander through a voicemail maze while being forced to listen to elevator music and enthusiastic ads. We had a long list of plumbing jobs--from ordinary tasks like slow drains to complicated ones like installing a Toto Washlet--that needed to be done. Ryan--who was a pleasure to work with--and an assistant (I'm bummed that I don't remember his name because he was great) got them all done and found a few issues we had forgotten about. They were friendly, explained everything, and answered questions. It has been a week since they've been here and there have been no unpleasant surprises. Everything works as it should. I will definitely be calling back the next time I need plumbing work done in my house. read more

I had a water heater situation. The one that I had went out. It was still under warranty, so all I had to do was take it out and bring it back to Home Depot. There in lies the problem. I have no idea what I am doing. So, I called around and the 1st plumber wanted nothing to do with it. He wanted $750 and said it would be a week. Then I got in touch with Dan at Welter (recommended). He explained the major cost was time. Bringing it back and dealing with HD was going to be a major pain. He quoted me about $500. Then he explained he could put in a new one for $975. The new one was much better than the piece of junk GE heater from HD. Fast forward to the replacement, and it was great. The guys were on time, cleaned up after themselves, and were in and out. Outstanding job by Welter. And, the $975 I was quoted on the phone - Exactly $975. Not a penny more. I did initially expect there to be some extra charges. Awesome place to do business with. I would most certainly advise to give them a call for any plumbing needs. read more

I have nothing but good things to say about the guys at Welter. They came out right away and diagnosed the problem. Even though they were unable to do all the work on the spot, they did do a temporary fix for me and set the appointment to come back. Another company was suggesting a very expensive solution, but Welter told me it was not necessary saving me thousands of dollars. read more

Love these guys. Basement backing up. They made an emergency call. Worked late. Then came back in the morning to put an external access point in. Pulled permits and everything. Good pricing. Cheaper than their quote. We had the roots grow back in 3 months. They came back and rodded the out at no cost. These guys are it from here on out. read more

I moved into a new house a month ago and the previous owners had advised it was good practice to have the main line rodded every 1-2 years. There is a big tree in the backyard with some deep roots so I called a few plumbers in the area for quotes. Weller plumbing had a very competitive rate and based on other reviews I gave them a shot. On the phone they quoted me the price for an hour and if it goes more it's $50 every 15 min which got me nervous hearing that. Jesus and Daniel, the techs, arrived on time the day scheduled and completed the job under an hour and even put a cover on my sump pit for next to nothing. I will definitely continue to use these guys for my future needs as I appreciate honesty and good work. They were very nice and did a good job within the price originally quoted...that's all you can ask from a plumber! read more

Our kitchen drain pipe behind a wall cracked and leaked into our basement. On 6/22 Jesus and Johnny came, they had to pull the dishwasher away from the wall, cut into the wall and cut out the broken pipe. The new pipe was installed in 2 hours, afterwards the guys cleaned and vacuumed the work area. The guys were knowledgeable and friendly. We are happy with Welter's service and price point. We've been using Welter for over 25 years. read more

Eric and Victor were here today and we can't even begin to say how happy we are . We actually had two other plumbers out in the past 6 months and Eric is the one who did things correctly and solved all our problems and made complete sense . He told us things and found things for us that the other two companies didn't even think about. These guys are definitely our new plumbers from now on and we are just thrilled .The price was awesome too. Our neighbors recommended them to us and others in our neighborhood are using them and it's clear why . We purchased this new home in November and we had so many plumbing issues and concerns . Eric and Victor did camera work and actually got out to the main line, inspected and worked on our catch basin, found where kitchen piping leads , implemented ideas about how to make sure certain piping was what they thought it was , inspected our ejector pit , gave us advice on bathroom issues we were having , FOUND our flood conTrol system that nobody else cared enough to find nor could find , went down into it , explained our old system to us and recommended what type of electrical we needed to make sure our pumps stay working and told us how to maintain our systems , told us about the different systems our neighbors have and why they are the way they are , I could go on and on . But suffice to stop here and say I cant tell you how relieved we are to finally on our 3rd try find this company and these men. They also are very kind and caring and love what they do. It was obvious . Epic crew and company ! Thank you Eric and Victor. read more

I have used Welter several times in the last 20 years - each service call they were prompt and efficient - and leave the space cleaner than it was before they arrived. This time, they got to my house w/in 5 hours of my call and were able to give me a small time frame during which they'd arrive which made it easier to work around our schedules. Their prices are always fair, as well... read more

I called Welter plumbing to set up an appointment for them to come out and give me an estimate on a backup battery powered sump pump replacement. Given the current system's age, 10+ years, I wasn't sure if it would be prudent to have it repaired or if I should have it replaced. Once the plumber learned that my current backup was a high quality system, trusty warns, he encouraged me to contact the company to see it if it was under warranty and, therefore, worth repairing & keeping. After a few minor adjustments I found out my old system was still good and no replacement was needed. Because of Welter plumbing's counsel I was able to have an operational backup sump pump without it costing me a dollar. When I was considering buying a replacement backup sump pump, from an online supply house, they gave me sound professional advice on which model to purchase from the zoeller company. This is a good,honest business that will assist you even when they don't stand to profit by doing so. I will highly recommend this genuine company to my friends and neighbors when they are in need of plumbing services. #RockStar read more

That charge of 425 dollars was a bill for two service calls. The first call was for a blocked sewage pipe for 125 dollars and took about an hour. The second charge of 300 dollars was a re-routing of a toilet drain that took close to 3 hours. I still feel that my charge of 325 dollars was too high to replace a shut off valve that took just over one hour. read more

I've been using Welter plumbing since 2006, and they've given me great service. Dan and his associates are nice, professional, and seem to do a good job. I have them come to do annual inspections of our sump pump, backups, and flood control system. I have also had them do occasional sewer rodding, install a backup sump pump, and unclog the occasional sink/drain. read more

Outstanding plumbing service! These guys are true professionals. They rodded the sewer pipes in a half hour and did great work. I will definitely be calling Welter Plumbing again! read more

This company quoted us an extremely large amount for work that they said needed to be done to our new home. Thankfully, we got a second opinion and were told this work was unnecessary. Though we did not end up using Welter Plumbing, they STILL sent us a very LARGE bill for coming out to our home. Before their arrival, they never indicated we would be charged for a quote. Though I believe some charge for their time is fair, the bill amount for just looking at our plumbing was ridiculous. read more
