Recommended Customer Reviews

Great service and reliable. Have had them out twice since I've been in my home and each time they were able to fix the issue in a timely manner

Great service. Reliable. Nice personnel. No bull. Knowledgeable. Highly likely to hire them again. May even sign up for their HVAC maintenance program. I really like it when local businesses are great businesses.

We had guests for the weekend. They told me Friday night at almost midnight that 2 drains were clogged. Lantz's team was out there by noon on Saturday, fixed both items and gave great advice on prevention. I love them!

My septic tank alarm sparked my call to Lantz's Within 12 hrs Brandon was dispatched after the office emailed me a pic and bio. I am happy that my 3 yr old pump was not the cause for the alarm. PVC pipes melted from the recent extreme heat. When the cap was lifted off the tank at 8 am boiling hot water was observed. Brandon replaced the pipes and had time to check on a few other small plumbing issues inside my house. Check out this companies Yearly Fee to Maintain all your home plumbing , HVAC , septic etc needs. Same day service for members !

Water heater stopped working. Not only did Lantz come out way after hours to fix it but also honored the warranty! I can't say enough about this company..ever time I have an issue they respond fast and are extremely fair. I will always use them and recommend them. Brandon the tech went way above to make sure it was fixed right... thank you

The quote process went smoothly; the guy (Mark Milner) that showed up was on time and very friendly. We received the quote within a couple days and we were very happy with it and so we planned to proceed with Lantz. However, we were told *multiple* times by the lady responsible for handling calls and scheduling that she needed to discuss with the guys to determine how many days required. We waited a week, then called her back, being told that she hadn't found time to talk with them about the days required (what?). OK, this happens 3 times(!); we call to see if she has dates yet, but somehow over 3-4 weeks, she has not found the time to schedule our project. Very disappointing as we had a great experience with everyone and the quote process except the gatekeeper on the other end of the phone line. We eventually went with Dennis from Gotcher Plumbing - I can't say enough good things about Gotcher - his quote was better the Lantz's, he was a great communicator, on time, and professional. I highly recommend Gotcher!

The skinny: Lantz employee tried to up sell us for $6K.
The novelette: Lantz employee showed up at our home in Lago Vista after both of our toilets were not evacuating. After taking off the top off, the person, actually a bad actor, said that it would be necessary to replace the grinder and electrical wall panel. He acted like someone/something died and the onrushing tsunami of waste was on the move up from below. He did scrape some grease from the walls of the container, did the same on the surface of the pump and cleaned the floats. Total grease ball taken was about 10 oz. Tested the current in the wall panel, said some numbers, declared that unit needed replacement when all that was necessary was to replace the small light bulb ($.59) on the panel face. Hosed everything down with water. When done quoted us $400 then reduced to $250.
Many homeowners are terrified of waste back up, jumping in a turd bucket with live electrical connections, finally to surface covered in toilet paper, coffee grounds, and anything else the homeowner could flush, shove, dump, and or permit to eliminate from their premises. How did Lantz come up with the $6,000.00 price? A bargain? A rip off? Astrological advice? I could buy my Italian sports car for that amount.
Take some ownership of your waste-it may come back to haunt you! Nothing but toilet paper-no Charmin either. Educate your self on the workings of your household, what has gone on with neighbor's waste systems-offer to buy a lunch for their testimonial, look up prices online. If you got the money, sure, have them do everything that they can get away with, but if you would like to evacuate from your wallet the $6K give it to Northlake so they can pave the parking lot!

Lantz's has a fantastic team of technicians and their customer service is amazing. We never have a problem getting an appointment and the technicians are always professional. We've worked with Lantz's team three different times and never had a bad experience. You've made a customer for life!

This company was referred to us by a very pleased client. We had a busted valve o a holding tank during the deep freeze of Feb 2021. He got to us ASAP and did a super job of getting our water back on. Reliable and Trustworthy. We will use him again when necessary. His price was reasonable and we appreciate how he took care of us. Thanks.

I highly recommend Lantz Lakeside Plumbing for your plumbing needs no matter how large or small the project is. Matthew arrived on time with a courtesy call prior to arrival. He was very professional, knowledgeable and friendly.
