Recommended Customer Reviews

I would not recommend this company. They quote you a $49 charge to come to your house. However, when they get there, they will charge you $165 per hour to diagnose where the leak is. Then, they will charge you another fee to fix the leak. In my situation, the charge to fix the problem was $650. A total of $864. I ended up paying the $49 + $165 for them to diagnose that there was a leak. I then found another company to fix the leak for $180.

Patrick did an excellent on replacing the toilet in my daughter's condo. I was impressed with his thoroughness and professionalism. He arrived for the work on time and kept me informed throughout the job. I will ask for his services again if I need plumbing work done in the future.

Santhoff Plumbing rescued our HOA from the woes of Charlie's Plumbing. When you call Santhoff, you can expect the repair to be done right the first time. They treat us as if they were condo owners at our complex too, and they always respond quickly. If you want your plumbing issues resolved the first time by experts in the plumbing industry, then call Santhoff. Don't waste your time with other plumbers in Houston. Santhoff is the best!

An extremely dishonest company. Initially called to ask what it would cost to diagnose an issue with our water heater and was told it was $49. Upon arrival, the service tech said it was $150 min to call the manufacturer plus parts. Tried really hard to sell their lack of service and complexity of the tankless water heater without even looking at the setup or the manufacturer. Spoke to the service dispatch person after discussing what had happened and the person who originally answered the phone only disclosed the $49 service fee but not the $150 to do any actual work. Hard to imagine that's standing behind their work and being an honest company when there wasn't disclosure of the costs.
Similar feedback to other reviews about a bait and switch type approach. Please consider using other vendors if possible.

Santhoff replaced a water heater for us last year. So, when our bathroom pedestal sink developed restricted water flow issues, we called Santhoff to find and fix the problem. Jose arrived on-time and without complaining about having to wrestle with a pedestal sink, found a clogged "water saver" part and solved our problem. He secured the wobbly bowl to the wall and pointed out a old-style flex hose at the adjacent toilet that should be replaced (I will do this). Jose was prompt, courteous, skilled and cleaned up upon finished. I will continue to use Santhoff in the future.

Manuel Andrade came to our home at the scheduled time and quickly analyzed a variety of issues and presented options for solving each issue in a cost effective manner. We would definitely call on Santhoff and Mr. Andrade again.

Fair and thorough. Had issues with main sewer line at my rental property. They took care of it.

Extremely pleased with our experience with Santhoff Plumbing. Mike arrived early, got the job done quickly and was super friendly as well. Highly recommended!

Cannot recommend Santhoff Plumbing Company highly enough. James came out late evening yesterday after heavy winds had blown out the burner flame. I could not get the pilot igniter to kick in. With kids in the house did not want to go through a second day without hot water. James took his time methodically diagnosing the issue and educating me on troubleshooting as he worked. He stayed until the job was done all the time with a wonderful smile. James, you sir, are a thorough gentleman and you came through WHEN my family needed you. Thank you.

Excellent service and fair price, thank you so much. Sergio did a great job. Will use your company and tell others to do the same. Highly recommend.
