Recommended Customer Reviews

We have called on Custom Plumbing for several repairs in our home over the past few years. They respond very quickly, take care of our needs in a courteous and professional manner, and take care of business! We have never had to call them back because of a problem after a repair! Their serviceman Mike was in our home this morning, was respectful of our property and fixed a problem under our kitchen sink that has plagued us for a very long time! We highly recommend Custom Plumbing for your plumbing needs!

Good installation and knowledge, but am rating Texas Best Plumbing as the worst company for communciations with the customs and NO CLEANUP after the job. They came back a second time and failed to cleanup all of the cutting, tubing, fittings. I waited an hour for them to finish only to discover the 6 workmen had left the house without telling me.
I had to clean up after them in the shower stall, bathtub, and outside.
I think their knowledge about repiping is superior, but the worst company in communications. I paid a premium price for this only to find I have second thoughts about referring them to anyone else lest I would not put anyone else through the mess.

I've used this company a couple of times. They always respond fairly fast and get the work done fast and good also. I will be using them again when needed.

They talk about their "integrity" yet when following up on a shower wall leak a short while following their tub-to-shower drain repairs last year in May, they still charged me $295 just to come and look, totally misdiagnosed the cause of the leak saying it was from a nail or a screw through the sheet rock which made a hole in the Pex pipe and refused to make good on any reimbursement when I had another company repair the leak which turned out to be on the outside wall side of the shower, at one-third of what Custom Plumbing was going to charge me. I even sent Custom a photo showing the leak and they STILL came back to me saying it was from a nail/screw!!!! Impossible deduction with photographic proof showing just that!!!

Just a caution to anyone using their services. Their hourly labor rate apparently is $600. We recently called them out to our house in Georgetown, Tx as they were listed by our builder as the company we should use with our hot water heater still under warranty. They sent two plumbers to the house and decided the gas control value needed to be replaced. There was no charge for the value as the heater was still under warranty. They left and returned to the house within the hour and replaced the valve, (one plumber worked, one just watched). The replacement took about 20 minutes. After they left, the hot water would not turn on, so had to have them come back out because they forgot to turn the water back on and needed to reconnect one of the pipes that they had previously disconnected. Spouse paid the invoice and after realizing the full charge was for labor, I called and talked to one of their reps the following day about the hourly rate, (which he felt was excessive). He spoke to the owner and the rate stands. Final bill was $625.
I kind of feel that if we weren't seniors, this would not have happened. Very disappointing experience, so be careful with this company.

I am a maintenance man and referred this company to my customer to do a job that I couldn't do. Mike their plumber not only completed the job in quick order, he also noticed a problem with their water softener and instructed them on the correct operation of the softener. The customer is very happy with the service and so am I. The price also was very reasonable as well.

I had a leaking faucet on my Jacuzzi tub and they fixed it and two months later it started leaking again. I called and they told me they would not repair it without charging me again. I had to contact another company and they fixed it with no issue. These guys really don't know what they are doing. I thought I would save some money but you definitely get what you pay for BEWARE.
Do not call themes

Watched company vehicle m-5877 drive through a stop sign and crosswalk while pedestrians were crossing. Passenger in vehicle when confronted attempted to fight person in a public parking lot, and when person wouldn't engage started yelling at them from company truck.

I am so thankful for the great and thorough job the guys did! I had a gas leak in 3 areas 2 at the stove and one at the water heater and they were able to take care of all 3 with no problems and very quickly. Communication was great!

I am a property owner who lives out of town. Custom Plumbing did all the initial work for the entire property when the two houses were moved onto the lot in 2009. The work was excellent. In April of 2019, the charge to flush two tankless water heaters at this same property was $360 -flat rate of $180 per unit regardless of having two units at one address. Two years later in April 2021, the rate for two units is $500 before a discount for having two units at one address. The end charge was $435 plus tax, over 20% increase in two years even after the discount. My complaint: no discount two years ago (i.e overcharged) and overpriced two years later.
