Recommended Customer Reviews

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.

Reliable and showed up on time. Did excellent work and performed additional inspections at my request to ensure my system was in good working order. No questions asked and no hesitations. The plumber, Sergio, was knowledgeable, efficient, and courteous. He answered every question and addressed all of my concerns. He was thorough and didn't suggest any unnecessary work, like other repairmen have done in the past. Truly excellent. These guys are going in my contact book for all my future plumbing needs!

Our upstairs bathroom drain was clogged. Our a/c unit drain was connected to that drain. Our charge was $605 to clear the drain. We don't believe that the drain was unusual. Our house is a typical Village Builder home in a neighborhood. We asked the office to review our bill. They indicated it was all in order. The drain was cleared, but the charge seems inordinately high.

I would not recommend Santhoff Plumbing Company for anything more than the simplest plumbing issue (replacing a fixture?). We used them for over 10 years for minor plumbing problems but when we had serious issues and really needed help, they were a huge disappointment and ultimately cost us a lot of extra money, time, frustration, loss of use of our sinks, showers and toilets, and water damage to our home.
I had them out recently for two different, serous issues and both times they failed to give a thorough diagnosis of the problem, did not explain to me that the problem was not fixed when they left (even though the invoice said "drain cleared"...it was not), AND, never followed up with an estimate for the repairs they said we needed. Frankly in retrospect, I think they were just lazy, didn't really want to do the hard work that would have been involved, and had no motiviation to do a good job for the customer.
When our problem occurred again, weeks after Santhoff had been out, we called another plumbing company and they spent 4 1/2 hours looking for where the problem was that was causing our toilet to back up. They pulled up the toilet and brought in all kinds of equiptment. In contradiction to the folks from Sanhoff, the new plumbers were very thourough and did not quit until they KNEW what was causing the problem. They showed us the camera images of the damaged pipes so that we also could feel confident that this was indeed where the problem was. I must mention that the pipe that was acutally the problem was not even the pipe that the guy from Santhoff said was the problem and so, IF they had ever gotten back to us with an estimate for the repair that they recommended, we would have completely wasted our money having that work done. I also know from my interactions with the person that answers the phones when there is a compliaint that we never would have gotten our money back for the wrong repair they would have made. They have a justification for everything and cover themselves so that they basically don't have to truly guarantee their work.
This company has lost out on one customer and a large amount of money that we paid for a very large repair, over $8,000. This should serve as a reminder to them that you should treat all customers well and give great service because, even though it may be a small repair today, you never know what they will need tomorrow. Very, very disappointing.

This is an old-fashioned company-they stand behind their work and all of their plumbers are professional and have a great skill set.
I can't imagine using another company. I feel like their pricing structure is very competitive, and there have been no service or billing problems.
They are not the biggest plumbing company in Houston, but one of the best.
I highly recommend Santoff.
